GM Authority has received a growing number of emails and messages from General Motors pickup truck and SUV owners experiencing valve lifter problems.
Some of these owners are stating that their vehicle has been at the dealership for several weeks while waiting on repairs. The valve lifter issues seem to concern the naturally aspirated 5.3L V8 L84 gasoline engine and the naturally aspirated 6.2L V8 L87 gasoline engines, which can be found in 2019-and-later model year Chevy Silverado 1500 and GMC Sierra 1500 pickups, as well as 2021-model-year full-size GM SUVs, including the Cadillac Escalade, Chevy Suburban, Chevy Tahoe, and GMC Yukon.
To note, the naturally aspirated 5.3L V8 L84 is rated at 355 horsepower at 5,600 rpm and 383 pound-feet of torque at 4,100 rpm, while the naturally aspirated 6.2 V8 L87 gasoline engine is rated at 420 horsepower at 5,600 rpm and 460 pound-feet of torque at 4,100 rpm.
Repairs for the V8 engine valve lifter issues are currently being performed under warranty.
The uptick in complaints from GM Authority readers regarding valve lifter issues follows a service bulletin issued in September of 2020 addressing valve spring issues in newer 6.2L V8 engines, including the L87, LT1, LT2, and LT4. The service bulletin states that certain GM V8 engines may produce a service engine light, along with a misfire and peculiar engine noise, which is the result of faulty valve springs. The bulletin instructs technicians to check for a broken valve spring and, if necessary, perform a cylinder leakage test. For other GM V8 engines, including the L82, L84, and L8T, technicians are instructed to replace the affected valve spring, and if there is a cylinder leak, perform further inspection to determine the extent of the engine damage.
A report from GM TechLink also indicates that GM pickups and SUVs equipped with either the L84 or L87 could experience a “misfire condition with a bent pushrod that leads to a collapsed lifter or the lifter comes apart.”
GM Authority will follow this story closely and report back any further updates as we receive them.

I have a friend who is tech at a big GM dealership and he told me about this last week. He state it is a supplier issue and they were told GM is working with the supplier and trying to figure out when the parts were made so they get them fixed asap on more vehicles. He said the lifters/springs are cracking from a manufacturing defect if there is no damage to engine he said they replace all of the springs/lifters on the side that is has the problem. Anything being built now should be fine.
Do you know who the supplier is and manufacturer location?
I believe it’s the former Delphi Technologies in Mexico, now part of BorgWarner.
Thanks for the info Sam. I really wonder if GM and the other manufactures are really better off outsourcing this stuff to 3rd world countries. At least its not China.
Stuffs been made in Mexico decades and from what I experienced it’s extremely well made the country is third largest auto exporter in the world. My 01 Silverado from factory with 350 thousand miles has made in Mexico parts that have yet to be replaced.
What about the transmissions the 6 speeds go out around 120,000 I know personally 6 friends including me that had to replace transmissions the years 2014 to 2016
I find it hard to believe that this is simply a part defect due to material or poor supplier quality control that was recently discovered in a limited production series and all is well now. This problem has been reported in large numbers on engines manufactured in 2019 all the way to 2022. GM is just now discovering this as a supplier issue? And now everything is fine? I think a certain number of pushrod issues in certain manufacturing lots were caused by faulty parts but the vast majority of the lifter failures were outside of this limited batch. And the fact that no one in GM is openly addressing this issue speaks volumes. I guarantee you that we will continue to see engine failures in very recently manufactured and sold trucks and SUV’s. Stay tuned.
Mine is a 2014 Silverado with the ecotec 5.3L V8. Last summer I had to have all the lifter replaced due to one collapsed lifter and two weeks ago it bent a valve on the opposite bank from the lifter issue last year. 152,000 miles on the truck.
I have a 2021 GMC 5.3L with 15k. Just got it back with one side having all lifters replaced. Hope the other side doesn’t go bad. I cannot understand why they would not do both sides when the engine is already torn down.
My 2021 GMC AT4 with the 6.2 failed completely on one side. The dealership was instructed to repair only the faulty side, as indicated by the service writer. I strongly objected and made note of it in the transaction and in the review. That was at about 11,000 miles. I am now at 28K and starting to hear noises just like the ones at the first failure. Took it to the dealer who indicated they did not have a technician available to inspect and recommend for a couple of weeks. He assigned me an appointment for June 2. I am inclined not to accept a repair of just the failed side this time, only to see another failure due to floating debris. This is not acceptable. There are rumors on several sites stating that GM is offering 6 year/100,000 mile extended warranties for vehicles affected by this debacle. Anyone know if this is accurate? Anyone a part of a class action? What are you hearing.
Following, I have a 2021 at4 GMC and had the same problem, would only change one side. Happened at 15k miles. Would love to see a class action where the very least GM would supply a 100k mile warranty…
Yes I got my local dealer to do both sides when one failed on my 2021 Denali with only 8039 miles back in January and then followed up on the CCL ( component coverage letter) extending engine warranty 100k miles and 6 years.
I have a 2021 AT4 5.3L . At 23k it had 2 bad lifters and a bent push rod. that is all they replaced. Now at 25k it is in the shop again with more bad lifters. I repeatedly asked why not replace them all. Was told it is GM’s policy to only replace the bad parts.
I ran out of warranty at 60000 miles. I am paying for repairs, anyone with solutions?
2020 Escalade went bad on 1 bank at 76K 3K out of warranty costly repair GM covered part of it, took 2 weeks to get all the parts. 30 days after the same issue, the dealer had to replace it again this time they paid for it. 2 years unlimited warranty. At this point, Im questioning myself if I want to keep this money sucker it is not a reliable SUV.
Concur,, 2018 6.2 Denali higher mileage well cared for and all synthetic oil etc Now awaiting manifold, and lifters as loud click and apparently bent push rod
How long did you have to wait on parts? Any more issues after it was fixed (assuming it was fixed)? I’m currently waiting on same parts with no ETA…..
Did the dealership charge or covered?
2019 my ass!!! MY 2015 Yukon Denali broke a valve spring at 30K miles! I was anal about OIL changes and maintenance. Both banks got new springs, couple Pushrods replaced, under OE Warranty. Thank God.
Happened again at 58K and I thankfully bought the Bumper to Bumper Extended Warranty ( for $3K /36K miles/ 3 years) from GM Dealer….BEWARE “Car Shield” jokers !! Total SCAM!! Friend was burned!!)
I am getting rid of ANY V- 8 GM engine . Going Jeep Grand Cherokee. Tired of breaking down at nite w almost Zero engine power and waiting for flatbed tow! GM doesnt care. A total RECALL is needed. I had to supply ALL SERVICE Records for the Warranty people, Thankfully I had ( Some were Non Dealer Oil changes!!). $ 5500. each time!!
So I dump the Yukon or pay $1000 a year for Extended Warranty and wait 3 weeks for repairs each time. BYE BYE GM….
Too bad as I love the trucuk….. $5500
I just purchased a 22 GMC AT4 My truck was just put into the shop with lifter failure at 3000 miles with no check engine light that never came on. I was the one that Notice the ticking from the motor . The dealer would not accept That it was a Lifter issue until they diagnose vehicle and it came back as a bank 2 lifter failure. They only want to replace the one lifter how can I go about getting all lifters replaced on both banks
On mine, they replaced the one bank of lifters, with 3k they should replace both. I am now getting a check engine light again with 18k. What trash! Mine is a 2021
Robert.
This makes even more nervous. I have a 2020 silverado with a new engine at 10k. I was going to buy a new one because I figured that the problem was taken care of. Now I’m thinking of switching to the Ram. I’m really a chevy fan, but GM is making this difficult for me. I wish all of us the best. GM needs to do the right thing and take car of their customers.
Sincerely a customer with a new engine with only 6k on it.
Well Ram has had their fair share of lifter/camshaft issues too. But I don’t think to the same degree has GM V8s have had. I think the source of their troubles the same in using variable displacement technologies which play hell with the lifters. Amazing that the Big 3 all used to make V8 engines using flat tappet cams that would run for years without issues.
To save $$ at our safety/inconvenience peril! My friends 2023 V-6 Caddy XT-5 No more GM for me!
Ram is having the same lifter issues as gm. ford is having all kinds of problems, what are we going to buy? i have been looking and researching for over a year and i cannot find anything worth while to buy that is american named, because nothing is american made. Maybe put together in the u.s. but not made here. Anyone with any thoughts, please let me know because i am almost buying a toyota and calling it a day!
What is the build date on your VIN sticker and did your truck have the chip for DFM? Thanks
Agreed, i bought a used GMC Sierra 1500 5.3L with 105,000 miles within a week of the purchase I had to get the transmission replaced with a reman. Then front upper ball joint, not been waiting on a motor I ordered from O’Reilly’s for almost 4 months…. (already paid in full when order was placed) because of a failed or collapsed Lifter on Cylinder 6. It’s still drives but it’s getting really bad and just blowing smoke that Cylinder 6 won’t burn.
Careful, if 6 is missing firing and lifter is bad, its possible for it to get worse, bend the push rod and and wipe out the cam.
Yeah kind of waiting on that to happen. They should still be fine with the core refund though I’m supposed to get back from the block regardless. Sure was hoping to get this motor first. Ordered the exact same motor, bought the OBD2 delete kit, then about a month ago finally got a call from O’Reilly’s Stadium they found somebody that finally has an engine they’re about to get started on it but it’s going to cost another $2,100. This is not including the $4,995 I paid when I made the order. Then Wednesday I get a call apparently everybody is waiting on cam bearings so they’re at a stop.
Yes suppose to.be ordered or produced in Indonesia
I have 3000 miles on my Z71 and it’s starting to develop a tick sound from the engine
gm should have to buy back every single pos they sold with bad lifters
Same here but at 5k on my z31. No misfires but a significant tick on front driver side 5.3
I’m dumping mine. I have extended Warranty…$3K for 3 years/24k miles.( That’s allI needed)
But I can’t handle getting stuck w family at 2AM in a Blue City!!
Bye bye G.M. ASAP

The problem I had with my 5.3 L V8 was bad lifters. My dealer rebuilt one bank of cylinders after the compression issues and ticking started. After doing some research, it appears the issue is the DFM causing cylinders to shutdown and lose oil pressure. When you hit the gas, the DFM activates the cylinders, and now there’s no oil, so the lifters or rods bends and eventually break. The tech said it happens much more often than it should.
The simple fix is to get a Range Disabler. It plugs into your port and disabled the AFM/DFM so your engine runs on all 8 cylinders all the time. There’s a slight decrease in gas mileage, but your engine will never have that issue again. It does not flash the system, so it won’t void your warranty. The only thing you need to do is unplug it when you bring it in for any kind of service. For $200, it’s worth every penny.
I have seen some recent posts about the lifter/push rod failure issues by owners with only 3K -8K miles or so in both the 5.3L and the 6.3L engines. So this indicates that the problem is a design issue and not limited to a batch of bad parts/supplier issue that plagued a certain models (and covered under a service bulletin a year or so ago) and continues in the 2022 models as well and will be the case in the 2023 models. Is my thinking correct or was this indeed limited to 2019-2021 engines? Anyone having this issue with 2022 model 5.3L and 6.2L engines?
KSM, the service bulletin that told dealers to change the lifters before the customer bought them was for trucks built 9/2020 to 3/2021. I thought I was safe with a build date of 8/2021, 5 months later. I read all comments on this article and the service bulletin article telling dealers to fix the engines before selling the trucks. One person had lifter failure with a 7/2021 build date and another person with 9/2021 build date. I’m right in the middle. The biggest indicator my truck will have problems is another person had lifter failure on their 2022 model year. I replied to them asking their build date, but didn’t hear back. So yeah, someone is having a problem with 2022 model year.
Thanks. Thats too bad – I think I will skip the Tahoe for my next SUV. I was hoping that they would somehow fit the new diesel engine (higher torque and HP) in the 2023 Z71 but thats not to be. I will shop other brands. Good luck.
KSM, you’re welcome. Yeah it’s crazy GM can’t get this right already. Several comments come from people saying they had lifter failure due to DOD parts in trucks from 10 years ago or however long ago DOD started. It’s been a decade or so long problem. You could still get that Tahoe and do what I’m doing, a DOD delete. It requires the rad, intake and heads to be removed to replace the DOD parts. A crazy amount of work considering it’s a new engine, but afterward, it will be a 250,000 mile engine. The DOD cam has to be replaced too, so you can put a performance cam in if you want. I’m doing other upgrades like getting rid of the needle bearing trunnions too. Check out DOD kits from Texas Speed and look on youtube. There are lots of people doing this, most after failure. If you stay with GM, the HD 6.6 8LT doesn’t have DOD/DFM, but you can’t get it in a SUV. Neither does the 4.3 LV1, but it’s a V6 and was only offered in the vans. The 4.3 LV3 is also a V6, (used in trucks) but it DOES have DOD, so stay away from that. The 4.3 was dropped from the truck line for 2022 anyway and not sure if it was ever offered in SUVs. I hope this gives you some more ideas!
Thanks again Dan for the detailed info. You are right – THIS IS NUTS to buy a $70K SUV and then have to do major open heart surgery on it. I have been away from GM products for well over 30 years but was seriously considering GM and had placed an order before this issue came to light. This coupled with everyday GM cancelling this option, then that option on my order, I decided that the GM solution was not for me. I know every maker has had and will have issues, but this is just plain un acceptable right out of the gate.
Trade that truck for a Mopar! ALL THE 5.3 and 6.2 engines will FAIL! A neighbor had the ENGINE FAIL ON THE TEST DRIVE!!!! 2022, 6.2 L.
Yes no eng /brand is perfect but GM leaves you stranded w NO RENTAL and only does half ass repair job. ( Not both sides umless it fails w less than 5k on truck!) and even AFTER the failure…it will happen again because they use SAME PARTS and same design flaw remains! ONLY possible savior is the new tech gadget ( AFM DISABLER) sold on Ebay/Amazon. I paid $115.
My 2015 w 74K miles is humming beautifullt now ( I got BOTH heads rebuilt because I bought an Extended Warraty years ago and they do NOT want to see me again!! I will sell back to GM BEFORE the Warranty runs out (2 years, unlimited miles). Cant even buy a Blazer V-6 because they put the damned Cyl Deactivation in that engine too!!! (6-4 cyl as needed).
Praying the AFM DISABLER I bought on Ebay saves me. If it begins to, or fails 1 more time……. It may get stolen……and Dodge here I come!~!
I have a 2022 Yukon SLT, 5.3L. Bought it 12/26/21. Just brought into shop with bad lifter on cylinder #8. 7321 miles. Dealer says they are changing both sides. i feel this truck is tainted and thinking about trading it in. But from what I am reading this same issue may still be present with the 2023’s. Ughhhh!!
I feel your pain and hope that once fixed this issue becomes a distant memory – but at least you are getting both sides fixed. Many are not, leaving a possible ticking time bomb so to speak. I was in the market for the 6.2L (towing needs) and still cant get anyone (including folks who work in the service dept.) to tell me what if anything GM has done to solve this issue (other than fix em when they fail). So I have placed an order for the Duramax 3.0L Diesel. I know fuel prices right now are sky high (especially Diesel even compared to premium gas) but based on my average number of miles per year it is still the better alternative and I feel more confident in that powertrain – I least I know exactly what GM did to fix the long/no crank issue with the diesel but have no idea if anything has changed on the lifter/pushrod issue with 5.3 & 6.2L. With so few miles on yours, it maybe a good time to make that trade.
Thanks for the feedback. The dealership called yesterday evening(Wed) and said my truck was already done which shocked and also made me feel better. I was just there Monday morning grabbing some stuff out of the truck(2 days ago) and the service manager said they were waitiing on parts the truck wouldn’t be done until later next week. I don’t know much about cars and lifters…etc but can this be fixed that fast?
I also just received a call from GM in regards to lemoning my truck and they said someone from the California division will be contacting me. At least I feel GM is being attentive to this situation.
Hi Benson
GM replaced the motor in my 2020 Silverado 6.2 at 10k. The new engine now has almost 10k on it and so far everything is working great. The one thing I did differently is always drive in sport mode. I’m not sure if this is the answer but so far so good.
Good luck my GM friend

Yes. I bought a 2022 gmc sierra. 5.3 v8. It had 7 k miles used. I had it for two days and the lifter went out and event push rod. Got it back and drove it for 3k more miles. And another lifter went out. It currently sits at 11k miles and 2 failed lifters and bent rods.
Ace, what is the build date on the door jamb sticker?
TRADE IT IN!!!! IT WILL FAIL TOTALLY AT 2AM ONE NITE….IN RAIN!.UNRELIABLE. 100%
There is way too much sales hype concerning a Range Disabler.
Defective lifter springs and defective lifter spring clip pins are the root causes of this problem.
I may sound arrogant but I refuse to purchase an aftermarket to circumvent what is clearly GM’s responsibility to begin with.
I have read 100’s of posts on this forum and some of them are really heartbreaking, and I’m sure many of them are truthful and valid. But some also are invalid because of just plain warranty oversights or omission of facts or circumstances.
I bought a 2021 Silverado new with the 5.3L now with 5800 mi. and I can hardly sleep at night for wondering when the engine is going out.
But, when it does happen, I will deal with it legally and get the repairs made to my satisfaction or be the squeaky wheel til it is.
Unfortunately, GM is one of those “too big to fail” entities and since the recovery from Covid supply chain shortages and resulting inflation, GM is making huge windfall profits. They will work through this issue based on statistical data and financial impact priority until warranty claims are virtually nonexistent.
That being said, all of us that think or know we have valid complaints should do just that. COMPLAIN !
First have a written list of what you expect for satisfaction.
1. Complain to the dealerships.
2. File with the class action suit.
3. Call the GM Customer Service number frequently.
4. If you do not receive satisfaction, Talk With an Atty. to learn what your options are.
I have a 2018 Silverado LT Z71. At 60K miles I got a flashing check engine light and a traction control symbol on the dash. The engine seemed to go into limp mode and was running very ruff. When I slowed down, it would down shift very hard.
Put an analyzer on it and it stated I had misfire on # 7 cylinder. The dealer replaced the lifters on both sides and installed a new manifold that I had to wait a month for. Everything seemed to be working well afterwards and I had no problem thinking that it wouldn’t happen again for another 60K miles. Two weeks later, the very same thing happened again. I did hear lifter noise just before it happened also. I told the dealer that I checked this problem out on line and there are thousands of owners with the exact same problem. When I told them the 5.3 was a piece of crap, they 100% agreed with me. They stated that the parts that they are receiving are not any better than the parts they are removing. This will be a NEVER ending problem and needs to go into a class action court case. I tried to trade my Silverado for a Toyota after the first break down but could not get a fair offer from anyone. Other than the engine, I loved the truck and will immediately trade it off after I get it back again.
Robert, I sincerely sympathize with you and I wish I had the means to help you and all the jilted GM owners who have suffered the same problem. Unfortunately, it seems to me that GM , the legal system and our government have a close relationship that Does not see a problem as long as GM Continues to make repairs to the vehicles until the warranty expires. I see so much venting of frustrations on this forum That I have to wonder if this forum works in favor of GM also. JMHO.
“Sorry Charlie”. Had it recently in my 2015 Yukon Denali (74K) and know a guy had engine crap a Lifter ON THE TEST DRIVE on a 2022!! Lol. A neighbors 2023 , V-6 Caddy XT-5 has a DOD engine too! ( V-6 to V-4) Insane!! But you’ll appreciate that extra 1-2 MPG as you sit broken down at 2AM on side of road in 20°F ! We were there!!! Bye bye GM
If that guy that went on the test drive was a youtuber with millions of followers and released that video, that would be extremely helpful in ending this problem. Would be great to show the mileage on the test drive vehicle and some comments from the salesmen and service manager.
John, sounds great, that was my plan too. The problem will still happen though based on my reading of over 600 comments, including the 445 on this article. My 2021 5.3 had 5 miles when I took the engine out. I won’t let GM touch it, free or not $. They will just put in more bad lifters and it will fail again. Do a DOD delete kit from a good company like Texas Speed and while you’re at it you can put a performance cam in. You have to change the cam anyway. You’ll have no oil psi if you leave the DOD cam in.
Dan,
Mine happened at 5,300 miles. I got the Disabler right after I picked up the vehicle from the dealer from the service. In theory, it should work since oil flow seems to be the main issue. Truthfully, I didn’t wait around to find out for long. I traded the Sierra in about a month later for more than sticker and got a 2021 Acadia instead. 27K later, and no regrets.
John, that was smart to disable right away and smart to get rid of it and wow, more than sticker, nice. That’s what the used car market was like for a bit. My truck didn’t even have the semiconductor chip to allow DFM to work, I thought I wouldn’t even have to disable it, thought I was totally in the clear. After reading several comments about it still failing with it disabled, I realized I could still have problems because I knew that even if the trucks didn’t have the chips… they still had the same engine internals.
Brothers All……I’m hearing that event he V-6 Chevys, GMC. Caddy’s have a damn DOD engine ( V-6 goes to V-4). Beware!!!!
If they’re going to do that, they should just get rid of the V6 and go I4. I’ve only looked into two V6s and the LV3 (1500 truck) has it, but LV1 (van) does not.
Referring to Mexico in this context as 3rd world country is borderline racist and seriously insulting. They are just like USA a developing country. No I am not Mexican
On the outsourcing in cheaper labour, it is a direct result of capitalism. Are we ready to pay more and have our companies make less profit? If not….can t complain….
Most of my Mexico built trucks have been better than my US build ones. And that holds true for GM and Ram.
Your sensitivity makes me vomit, Mexico is a third world country for many reasons, it’s a fact.
Large companies love having their products made by people that will work for $5.00 an hour, but still make us pay top dollar when they sell their items here, in the states, pocketing huge profits.
Residents of third world countries settle for peanuts because they are accustomed to having nothing.
Because that’s how people live in a Third world countries.
So is Detroit a 3rd world country.
I have an 07′ Gmc Sierra WT. 323k miles. Did have lifter problems at 177k. Good run? Opted for new crate engine. Haven’t had any issues with engine. Will need truck in future. Don’t want lifter issues or any other issues associated with any new truck. I suppose they all have some kind of issue. Just remember this folks. The consumer is always in control of one’s wallet! As much as I have enjoyed my Sierra, I only have one thing to say to GM. Get it together before you are just a memory.
My 2019 sierra Denali lifters just went out at 64,000 miles they are refusing to pay $5000 out of my pocket I’m going for an F2 50 super duty!
FAIR SPEECH MORON WOKE , PULL YOUR HEAD OUT AND GET SOME AIR ………
Sorry but even though Mexico is developing country it is still considered 3rd world and probably will always be as long as the drug cartels continue to run it, race has nothing to do with it, as far as the USA is concerned, it has a modern fully developed economy.
racist??? really?? mexico is, was and will always be a THIRD WORLD COUNTRY… you are whats wrong with this world, reach down, pull and pull your panties out of your ass and get on with your life Karen….
They are not like the USA and if it was so great there than why are they all trying to come here you’re right it’s great there return to your home country! And if I buy a Chevy which I own I want it to be be made in the USA I’d rather pay a little bit more than have some Third World country making parts for my American Truck !
Hello from my experience I would rather have a truck made in Mexico than a pos chevy. They don’t last 5000 miles. My 2020 chevy left us broke down. Toyota will run forever
Tell me you voted for Joe Biden without telling me you voted for Joe Biden
Mexico is a third-world country and I’ve heard this all 65 years of my life. Before you go into cheap labor look at all the slave labor stuff you by from China and how sorry Biden wants to drop all tax tariffs to reward them for infecting the world with a virus by silence. Get off you racist everything cry baby lazy @ss Mr. or Ms. Fair Speech. You are entitled to your view but a whole lot more people are entitled to their despite our riots and destruction and stalking supreme court judges. The democratic socialist party is evil in so many ways and racism is their big excuse along with Putin-made gas and inflation. Were not idiot, but you might re-evaluate your name-calling self. You are the racist.
I was posting but have been following since. I have a 6.2 2021 Silverado. Lifters went at 7700 miles. Y’all need to know, your dealer controls most of this replacement and warranty whether they tell you that or not. My dealer got both sides replaced for me and gm covered it. As for the CCL warranty I went to gm first as my dealer instructed me too. Long story short gm came back and said dealer needed to fill out request. Went back to the dealer. The shop manager went to gm. Next day I get a call from gm customer service saying they won’t give it to me. Following day I get an email with the dealer CC in saying I got it. All because the dealer went to them. Don’t take no for an answer on either. Fight like hell and you’ll get both. The Dealer influences this regardless of what they say. They always start with lip service. Y’all know that.
Jim.
A similar thing happened with my 2020 chevy 6.2. GM said they would only replace one side. To make along story short. GM agree to replace both sides then to finally realize engine replacement was needed with only 10k. I let GM know that I was disappointed. GM offered to a payment as long as my payments were current. My truck runs great with new 6.2. However they never made a payment even though they offered. The dealership had my truck for 3 months.
Still disappointed with GM
Of course it’s from Mexico.
What did Scotty Kilmer say about Mexico quality?
Most of what Scotty Kilmer says is total BS!
Scotty Kilmer is a real Jamoke.
Only to the Ignorant, stubborn, fan boy cultist, or mentally fragile.
The truth hurts your fragile American ego.
Now enjoy having your wallet bleed in agony.
Actually what Scotty Kilmer says is the cold hard facts.
Just mentally fragile fanboys like you can’t handle hearing it.
Enjoy having your wallet bleed in agony. Maybe with enough pain you can join the ranks of the homeless & financially ruined. Stubborn stupidity has a price.
I have a 2021 Tahoe that’s been in the shop twice this year for failed lifters. 6,000 miles two lifters failed. Out of service 3 weeks. Only replaced the two failed lifters, wanted all replaced, Chevy would not do. Tahoe is back in shop now, two more lifters failed other side of engine, they only want to repair that side of engine and don’t want to replace the other lifters on opposite side of engine. I am arguing there are still two cylinders on the original repaired side of engine that have the faulty design and they all need to be replaced. It is like dealing with a bunch of children, all I want is a dependable vehicle, this is the most undependable vehicle and the worst customer service I have ever had. Looking at Toyota now, I really want to continue to buy American but I’m tired of this.
I have stayed away from GM products for 3 decades. Never regretted my decision. I must have had a brain twitch because I placed an order for a 2022 Z71 6.2L. Every few weeks its been one thing or another with feature/option availability. This week my salesman told me that GM is now going to pull the plug on the power sliding console. I was really getting cold feet reading all these issues and seeing consumer reports owner survey result rating of 1 out of 5 for these product reliability. I used this latest option availability issue to cancel my order and start my deposit refund process. Why would anyone spend over $70K for products that are so questionable? I very happily stayed away for 30 years and will continue to stay NO to GM.
My 2021 Silverado is in the dealership now with broken lifter and bent push rod, Week and a half. It has 8990 miles on it, this is a first in all the Slverado’s I’ve owned.
My understanding is GM is working with there supplier to try and figure out when the faulty lifters were produced.
This is a reason I lease a new one every three years, it’s under warranty. I’m not happy but what ya gonna do? If it happens again I’ll be changing to another manufacturer.
The dealer furnished me a a loaner truck, but it reeks of cigarette smell, I’ve ionized it 3 times, a little better.
My 2013 well maintained 5.3 just blew up at 102k and engine replacement was 8k dollars. Mechanic said this is to small of an engine for heavy trucks. Went to Hemi even with there 2% of lifter cam failure at 100k. Everything they make out of the US is junk
My 2020 Silverado Trail Boss just failed at 18k due to the lifters. It’s the 5.3 engine. I can’t wait to get it back though because it is an awesome truck and all things that are massed produced have some issues. I will always go Chevrolet !!
On October 18th GM issued their Component Coverage Letter valid for my 2021 5.3L Trail Boss which recently experienced a collapsed lifter and was repaired by my local Maine Chevy dealer. This letter covers a long list of engine components including all lubricated parts, block, heads, manifolds, mounts, etc. as well as modules, injection and water pumps, throttle body and the pressurized fuel system. It’s a six year / 100K miles extended warranty from my recent date of repair. This Component Letter is transferrable to any subsequent owner.
If you have experienced this lifter collapse problem you should go back to your GM dealer and request the CCL. You may have to fight like hell, but it’s worth it. I hope your GM dealer will go to bat for you the way mine has done for me.
General Motors knew about this all along and now we’re are a static we purchased a 2021 GMC AT4 and 6 months later we had to take it to the shop and load and behold it was the lifters? We were told they had no parts the $70,000 truck is outside for a month now. Had not heard anything from dealership my husband went to check on truck at dealership was informed that they received parts. Let’s see how much longer and how long it’s going to work without breaking down again? Is this the time to look into the Limon law? Trade the truck?
Thats fine if you drive your truck less than 100K miles. If you drive them longer, then good luck to you.. I have been driving Toyota’s with zero issues for well over 200K miles each. Sleep well!
I think it’s bad that you pay that much for a vehicle and before the first oil change that the dealer has to go in the motor for repair.
Fixing one side then down the road the other side goes out, they need to replace both sides with regular valves and lifers and get rid of the eco afm system that’s the problem.

2021 Cadillac Escalade the worst Cadillac ever made in my suv They replaced second engine
Guys whatever you do do not get this car because lemon law it will start after the fifth time problem now my third times they going to replace the engine again
My 2021 Escalade is in the shop for the 2nd time with lifter issues. I’m ready to get rid of it.
Should of bought a Lexus or Mercedes.
I have a 2021 Tahoe High Country that I brought in November 2020. It’s in the shop within the valve spring issue. 8323 miles on it.
My 2021 “Covid” Silverado High Country just suffered the lifter failure at 11,000 miles… Just dropped it off at the dealer last night and they just reported Lifter Issues to me….Only on the second Oil Change Full Synthetic and need to open the engine up….. 3GCUYHED3MG207729
21 gmc sierra 1500 at4, I had lifter failure at 1890 miles in February, this was when they only replaced the bank on side of the failure. Literally today 14,410 miles I heard a pop and a bang… Drove straight to the dealer… Same bank that was “fixed” failed.
Joe,
Is Chevy offering any money back due to the lifter issue? I know I was without my truck for a few weeks and they only replaced one side not both and it stated they should under 8,000 k miles.
Now I am having a paint issue with brown spots appearing on my White truck and it’s under the clear coat. Maybe break grease they used I am not sure and they can’t seem to determine. This is going to take around 3 weeks to repair since they are backed up. I wish they would just buy it back and I could get a new one.
When I inquired on this all I was given was an extension on my drive train warranty which in the end won’t help because I lease. The truck will be going back at the end of the lease and I will be done with Chevy’s.
My 2021 just went in for lifters and they were telling me they would only change 1 bank. The new motors have tighter clearences and are balanced motors. That’s how they get such high horsepower out of the new motors. When you replace 1 bank and not the other it isn’t a matter of if, but when the other bank is going to fail if not grenade the motor.
2021 Tahoe started noticing a issue at 600ish miles…. took it to the shop yesterday 1300 miles and bad lifters. I’ve only had it 3 weeks
I wasn’t aware of this issue till after my sons truck went into a garage to be fixed & now is costing me money to be done! Is GM going to reimburse people that can’t wait for a recall to have this fixed?
I have a 2014 that has the same motor and it sounds like the same problem I’m having
Unfortunately it’s the exact same problem and it goes back further than that.
Goes back to about 2002 and it’s effecting quite a few cars and trucks.
They excluded 6.0 in pontiacs
Prior to paying over $5k to get my 2017 Yukon XL engine repaired I specifically brought up this issue and asked if it were a parts thing, and they told me NO, its a manufacturing defect. And their resolution is to provide extended warranties. The new parts are subject tot he same problems….WTF?? So i sold my 2021 Tahie that i had just bought for roughly the same thing i bought it for 20,000 miles ago, and then once the enigne was repaired, i traded it in for a Ford Expedition Stealth edition which drives like a cloud. Got good money for the Yukon and am happily just sitting back and watching these emails roll in, forwarding a few to the attorneys that i hope will finally bring a solid class action lawsuit against GM on this.
Our 2021 RST that we’ve had for 11 months and had 10,000 miles developed an annoying tick last week. It’s currently in the shop. Bad lifter and bent pushrod. I’m just sick about it. I love my truck. They have no idea when the parts will be in. They say their on back order. At least GM is paying for our rental I guess. We have a 2002 Silverado we bought new that’s never gave us an issue besides a fuel pump. Still runs strong
Clearly this is not correct as we are seeing 2022 engines with around 3-4K miles having same exact lifter and pushrod issues. So no – nothing has improved and the root cause remains. GM continues to pump out junk and a 100K extended warranty or service plan is of little comfort if you plan on driving your $50-$80K vehicle more than 100,000 miles.
I am getting my truck out today for misfire on cylinder #8 and collapsed lifter. 2022 Yukon SLT 5.2, 7321 miles Dealer said they are replacing both banks. They finished the job in less than 2 days. I read in these posts about a tic, tic noise which I don’t think I heard in my truck. Wil the noise they are reffering to be coming from the front engine compartment when I am sitting in the drivers seat?
What I did hear is a clock/clock noise towards the middle/bottom and just to the right of the drivers seat. More like underneath the truck than under the hood. Almost sounds like a gear trying to engage.
On another note, I also hear a noise like a gear moving around just behind the gas pedal/firewall when the truck is off and I am sitting in the drivers seat. It make this noise for about 5 to 10 seconds. Is this a normal noise?
When it happened to mine, it was more like two cylinders were missing. Running Rough. They only did one side on mine so you are lucky you are doing both.
Your friend as a TECH, is being told this because he is in a NOT TO KNOW POSITION. He doesn’t have a clue.
I had engine replacement on my 2020 Silverado 6.2 at 10k. A friend of mine with a Corvette 2017 said to me he always drive with it in sport mode. He believes that these motors should be driven harder. So, the new engine in my 6.2 I decided to drive in sport mode. I’m not sure but 8k in on the new motor it seems to run better than new.
Time will tell My Chevy Friends.
I was asked if my 2015 6.2L Yukon Denali repairs were free or paid for , recently. ….
First repair at 48K was covered under factory 50K warranty ( broken valve spring). Done FREE. Got a loaner for 6 days.
Next ( recently-2023) @74K, lifter failed. I had a 3 year GM Extended Warranty ($3K my cost!) They were pissed about a $5300 bill from GM dealer( who did great job!!) Tuff.
The insurer did NOT want to see me again in several months I guess. So all 16 lifters and the special VOLM manifold replaced ( 14 day wait for manifold) I bought the plug in AFM DISABLER. But I now hear a lifter can still fail again. Poor quality/design??
Gonna sell soon and get a Non GM sled. I loved my truck….. 🙁 Can’t risk another breakdown in remote area with family, with a 2-3 week Repair. This aint no failed radio, muffler or tire…… A tow is needed!!
They did gjve me 2 years/ unlimited mile’s Warranty, but…… I wanna keep it 5 more years…..and a $5500 🤯 Ouch!!
Best!
I suggest anyone getting this repair done that isn’t covered under warranty to get the DOD parts replaced with non DOD parts. I said isn’t under warranty because I assume they will only use the same DOD parts that previously failed to do the repair if it is still under warranty. If it is under warranty, it doesn’t hurt to ask if they will use non DOD parts. Maybe they’d compromise with the customer and pay for just the parts or just the labor if the customer would cover the other, or maybe slip the service manager $100 to use non DOD parts and fudge the paperwork.
To Smoking Denali: Is the 2yr/unlimited mileage transferable to the next owner?
Dan. I didn’t ask cause I determined to trade it in. I doubt it though.
Damn shame cause I love the truck….
Best.,
Smokin’
Bought a sweet 1500 LTZ/Z71, 6.2L. Have enjoyed this truck since Feb. ’21.
At 93K I noticed ticking in the engine area – mostly at acceleration. Took it in and they diagnosed bent lifters. This is a company (fleet program) vehicle. I pick it up today – they replaced the lifters and camshaft, offering a 24 mo. warranty on the repair (no mileage limit).
Keeping my fingers crossed – was hoping to drive this truck for 5 years min.
On the other hand, I have had great success with the Nissan Titan Trucks – trade light may be flickering!
Fixing one side then down the road the other side goes out, they need to replace both sides with regular valves and lifers and get rid of the eco afm system that’s the problem.
Hopefully they get a handle on this ASAP, this could turn into a real PR problem if not addressed properly!
It already has. My chevrolet truck had lifter issues at 50k. My father-in-laws truck had lifter issues at the same time at the same mileage of 50k. Both trucks were bought the same year. I doubted buying chevy again this time after they took bailout money and seriously thought about buying ford. These lifter issues have all but made that decision for me.
I went to RAM after a series of issues with my GM trucks and I have never looked back 4.5 years in on my 2017 Ram with zero issues.
I had the lifter issue at 10k on my 2024 sierra. They only wanted to change 1 bank of lifters even though gm stated they needed to change out both. I had to freak out on the dealer to get them to do both sides instead of making my mother unbalan es having used lifters on 1 bank and new on the other. That is just putting a bandaid on a bullet wound. They changed out both banks and the bent pushrods and the truck has been flawless ever since.
My chevrolet truck experienced lifter issues at 9200 miles. It is currently in the shop. Definitely WILL not buy another GM product after this experience!
My 2021 GMC Sierra is in the shop right now for the valve/ lifter issue. Just a little over 6000 miles on the 5.3 L My question is , how reliable are the replacement parts ? Am I going to have this same problem down the road and out of warranty ?
This response is 2 yrs late so you probably already found out, but yes, you’ll have the same problem cuz they put the same crap lifters back in. You can find owners with comments of having it repaired, then repaired again, same problem. Good luck.
P.S. If it fails again out of warranty, have it repaired with non DOD parts. (DOD delete)
Dan Goodman….NO! They said the 2 year Rebuild job Warranty is Not Transferable !
Im looking around for another brand sled in near future . Maybe Jeep. Very sad. I love my Denali buy where I drive you do NOT want to get stranded with only 10 seconds notice and a full flat bed needed…if even possible within24 hours. No more GM for now anyway.
Smoking Denali, that sucks for the next guy. But since you love it and you know its weak spots, seriously consider doing a DOD delete shortly after the 2 years is up. Google it, look at the kits from Texas Speed and others. Contact them, get their opinion. I saw a comment somewhere on here, guy said his 02 5.3 had 400k miles! You could have a 250-350k engine easily I think without DOD in it to fail. I like Jeeps, never had one or know what fails on them, but there’s probably something that does, as with pretty much anything. At least with your Denali, you know the weak spots and you love it, so I’d say make it bullet proof and keep it!
More crap from lowercase gm, what a joke!
Seems that the General just got a demotion.
I have a 2021 5.3 Silverado and I have been driving GM vehicles since 1962. This is the first vehicle, new or used, I have been afraid to take on a trip for fear of an engine failure. GM should recall these vehicles and repair them before they fail. I have installed a Range DFM disabler. I hope it will help, but I am not sure.
Bought a 2021 Silverado in March, drove it to Las Vegas from Tennessee in July and it’s still in last Vegas.
We’ll go be fair. What happens in Vegas stays in Vegas.
I bought my 2021 Silverado and installed a DFM disabler at 500 miles. Today truck reaches 4400 miles bent pushrod lifer collapse it’s inevitable folks
The problem is for vehicle made from sept 2020 to feb 2021 coming out of the Mexican plant
Pandemic strikes again
so when should it be safe to start looking at gm again?
Good question. I’m staying a long way away. GM is not saying anything to limit a potential recall liability so it’s impossible to know if this issue is addressed properly. Keep in mind that there is a high failure rate with 5.3 and 6.2L engines from 2019 to todays engines with regards to lifters, pushrods etc. it ranges with engines with as little as a few thousand miles and up. If you drive your vehicles more than a 100K mikes then even an extended warranty (free from GM or paid for) is of little comfort. If you turn over vehicles every couple of years then at worst you face a week or a month without your ride. Its not worth the hassle.
Even if truck is made in Mexico, aren’t all the engines made in US? Do you have a link to that info? Thanks
Had a oil pump failure at 90.000 KM and two lifters cyl #1 at 99.000 on my 2014 sierra 5.3L that cost me 6300$ CAD.I miss my silverado 2004.Now driving RST 2020. Now you can say that they are garbage chinese truck.No more american truck.
Yeah. Those GMT800s were some of the best trucks GM has ever made.
They had their issues.
Drivetrain was solid.
Body was terrible for rust. Cheap brake lines. Bad gauge clusters. The damn tailgate issues! I can almost bet you any 800 still on the road has some or all of its brake lines replaced.
Weird the gauge cluster in my 2002 GMC Sierra works fine even after 257,000 miles.
2nd stainless steel brake lines are $800.
New engine or transmission or differential? THOUSANDS of dollars.
I much prefer the GMT400 trucks myself.
Those are even worse for rust.
If you drive in salty roads for 20 years you will get rust. Period.
Being in Michigan you just learn to accept the fact that if you own a truck here it will rust and just deal with issues like brake and fuel lines when they happen. I’ve had 3 different GMT400 trucks and for me the sweet spot.
I have seen a few oil pump and lifter failures, but never in one that was properly maintained.
Oil changes are cheaper than engine changes, and I currently have 420,000km on a 5.3 that has never been apart.
I guess all those folks who have had lifter, push rod problems before the first service interval should have changed their oil at 1000 or 2000 miles.
If they are Chinese then they can’t be American.
Maybe it’s time to go back to the 2000s trucks and save your $$$.
257,000+ Miles on my 2002 Sierra with the LM7 5.3.
ZERO engine issues
ZERO transmission issues
ZERO differential issues.
I’ve got a 99 tahoe with the good 350 runs great burns a little oil but starts every time almost 300,000miles on it, they need to quit messing with what works. these new trucks and the DOD system is junk, go back to what works, tell the R&D guys to quit over thinking things and build what you build best
My 2009 Silverado has the same naturally aspired 5.3 flex motor, Chevy is acting like this is a new problem. This problem should have been recalled years ago
My 2009 Colorado had the same thing. It plagues basically every engine with displacement on demand type systems. My dad’s 6.4L ram 2500 had the exact same issue too. It sucks, but it’s usually fixable… Just most people get scared off by having to replace the cam and lifters and everything.
yup! scared of that $6000 bill……
My 2002 5.3 has 407,000 miles and purrs like a kitten.
It’s either design or they’re buying crappy parts. Either way AFM is screwing up a lot of engines. Not all of them, but quite a few. All that pain to get maybe 1 or 2 additional mpg’s.
I would not doubt that the engineering for these parts has been done overseas.
More than likely.
gm has seriously dropped the ball on quality control.
A new 6.2 does not have afm or the lifters that caused the previous failures.
Different design so my guess is bad valve springs
6.2s do have AFM
Can you provide proof other than your statement?
I have never seen a 19 or newer option for a 6.2 with afm. They all came with the new dynamic duel management.
Totally different system.
They have DFM now. Dynamic fuel management. They can now deactivate all the cylinders not just the 2 on each side, so afm on steroids. Lifter and/or cam failure are happening more than you think. Doing at least 2 a month for years now. I believe it’s more people depending on the oil life monitor to tell them when to change their oil then doing it by mileage (3000-4000 miles). Oils cheap compared to these repairs. Just tore apart a ’19 that has already had engine replaced do to oil consumption and now is back because a lifter came apart and bent push tube. Quality seems to be lacking for such new vehicles.
Brand new 2021 6.2 with 6000 miles just failed us on long trip. Lifter. Oil changed at 4500. tow truck driver said he has picked up three already this year, brand new.
DFM
It has a slightly diff MECHANISM. It’s called DFM. A 2023 Corvette w 6.2L furnace, just crapped our w 52 miles onto the Engine!!! Fo not buy a GM sled….sorry..
It’s the design! Turn off the oil on a hot moving part and expect it to last,that’s dumb!!!
Not sure how thats the issue.
Neither afm or the newer skip fire turns off oil to moving parts that require lubrication. They use the oil pressure to create an actuaction the way a hydraulic cylinder causes movement. Those systems can last years with no issues.
To me dirty oil and poor maintenance seem to be a culprit. I just traded a 2011 yukon xl denali with a 6.2 afm 250k miles that still works flawlessly and has 35 psi hot. 6k oil changes with mobil 1 for its whole life.
But the afm systems definitely have added a level of complexity that I’m not sure justified the means
How could it be dirty oil and poor maintenance when they are failing before the first oil change is scheduled? My 21 Trail Boss is in the shop now waiting for lifters with less than 3000 miles on it.
I hear you. Same here, 21 Trailboss 13000 miles. Went in yesterday.
Same here 15,000 mikes
Happened on my 21 Tahoe two weeks ago. Replaced entire passenger side lifters and bent rod.
Today, same thing again. Drove it to the dealership and parked it.
Literally just had an oil change and 15k service done yesterday, and it failed today.
Same here. Yesterday. 2021 Trail boss 6.2 6000 miles left us hanging in middle of long trip. Lifters. One oil change 4500 miles. Tow truck driver knew exactly what it was, and confirmed when it got to dealer. He has picked up three already this year, brand new Silverado 1500’s.
2021 Z71 Tahoe, 8400 miles, lifter failure. Dealership is telling me they can’t replace all lifters, only the bank that failed. So they are literally setting me up for failure.
Have fun waiting for thr head gaskets, I’m going to be at 30 days before mine even sees the service bay.
Just went past 30 days on my 2021 RST Silverado. I think I’m done with GM
shouldn’t of bought that overpriced, unreliable 2021 Tahoe.
Consumer Ignorance has a price.
An idiot response to what’s happening.
If dirty oil and lack of maintenance is the issue, why is this happening to vehicles less than 1 year old and in some cases less than 1k Miles? Or in my case less than 1 year old and 4700 miles. My oil was actually changed at 4100 miles (oil life said 55%). Don’t give me the bull about it being a supplier issue either as the vehicle still isn’t right after all 16 lifters replaced and 4 trips back to the dealer. I’m actually in lemon law territory now and actively pursuing it!
Get your money back on that Lemon and buy a low mileage 2000s GM truck.
Then you won’t have to suffer through this again.
All because of the Govt. Mandate for Corp gas mileage.. 1 or 2 here or there by the millions adds up and they aren’t taxed by the Govt. for meeting the mandate, but we the consumer suffers.. govt. BS
And there is an easy workaround for that.
Don’t buy new trucks. Buy 2000s trucks instead.
Had this issue TWICE on my 2015 5.3 Silverado. Traded it for my 2020 5.3 LT. Now I read this WTF!
WISH I KEPT MY 2002 4.3 Silverado single cab 1/2 ton ….. bulletproof!
Trade in the 2020 for a 2000s GM truck.
You can still find good ones with under 80,000 miles.
Hey Evan! How much does GM pay you to comment your BS on this site?
Why would GM pay me anything to advocate for buying used older trucks? GM doesn’t gain any profit from it and in fact if the market shifted away from new trucks GM’s bottom line would take a huge hit.
You might want to think before you comment next time. Or just keep your American Ignorance to yourself.
Freaking sad they just dont make them with the pride like they use to
Scotty Kilmer (You Tube) was absolutely right!
I have 2010 suburban 400 k miles
No problems with anything in engine but always since I got the truck @ 50 k I use Mobile 1 oil and
LUCAS OIL STABILIZER. I still owns it
I have another 2015 Suburban , same thing, mobile 1 and LUCAS ,now 240k ,[ I need transmission ] engine runs perfect , btw oil changes 10-12k
10,000 miles on an oil change is extreme and foolish.
As Scotty Kilmer said. Oil is cheap. Engines are not.
This isn’t a new issue! My 2008 silverado had the same issue. It went to the dealer 4 times in the 4 years I owned it. Once for a broken valve spring and 3 times for lifters. I spoke with several people at gm about it and the only thing they really did was make sure I would never purchase another gm product. If it’s a supplier issue it still falls on gm to correct the issue. I would have thought if it truly was a supplier issue they would have found a new supplier by now. I feel bad for anyone who purchases one of these vehicle and my suggestion is always get rid of it before it drains your bank account.
Couldn’t agree with you more. GM should be installing new motors in these $60,000.00 plus cars and trucks. What a complete sham by GM. They expect you to feel good about spending 1 1/2yrs salary on their product than walk away from you when they have a problem. COMPLETE BULLSH*T. TERRIBLE CUSTOMER SERVICE !!!!
Just put a mask over the grill
I bought a Toyota Tundra, tired of GM engineering problems to keep their shops busy! For as long as vehicles have been in existence, we should be able to go 400,000 miles without any major problems!!
I changed to a tundra as well. So much better vehicle than the GM junk. There really is no comparing them. The tundra is old yet years ahead of GM in reliability. My Sierra had 31 issues and some major ones (motor) compared with my tundras 1 issue. The 1 issue with the tundra was the aftermarket remote starter that I had installed when I bought the truck. So far the Toyota has been flawless. Main difference is that Toyota has Japanese quality control while GM has none..
I worked at a Toyota dealership and to suggest they don’t have qc problems is disingenuous.
A reliable vehicle is not necessarily a nice vehicle …
Oh I know. Nothing says nice like spending nearly $100,000 on a truck or SUV then having it end up in the shop with a blown engine at 5,000 miles lololol.
Fortunately Interest rates are rising and the party is coming to an end.
That’s where I’m headed. The only truck that’s mostly built in the USA! The Japanese have their sh*t together and know how to build a truck. GM, Ford and Dodge have sold their souls to outside influence. It’s a shame. Never again will I purchase a so called American built car or truck.
Or you can buy an American Truck from the 2000s Like I did.
The 2000s GM Trucks are built as well as any Toyota and they cost half as much. Plus they are easy to work on and repair as necessary.
Active fuel management is the problem and the technology is not there. I used to be ride or die gm but the epa has forced things that are un doable good luck gm. I see you just invested a ton into some climate change bull. You better start thinking of your own future if you plan on being in business and stop letting the government shove you around
New leadership is required for survival. Someone who realizes happy customers buy again. Unhappy customers go elsewhere.
I am a GM technician at a store in Canada, we currently have four vehicles waiting for their lifters to be replaced. None of them have made it to their first oil change yet. The biggest issues is the lifters and head bolts are currently on back order. I read some comments claiming that it’s new “lower case gm crap” and if I’m perfectly honest, as long as these engines have had active fuel management this has been an issue. Why it’s such a big issue now is the lifters are failing way sooner than they used to. And it used to be at random mileage when it happened. Now it’s within the first 5-10,000 km. Another issue is gm keeps changing the way the engine deactivates the lifters trying to fix the issue, but it makes it worse. There used to be an oil manifold that is in the valley of the engine to control it, now it’s 8 individual oil solenoids.
Are these engines with lifter failure the newer design dynamic skip fire engines? Asking because I thought those designs used a standard lifter set and only the rocker arm was responsible for deactivation now.
The issues and bulletins are related to the newer Dynamic Fuel Management system specifically the push rod V-8’s, which uses a “spring loaded” lifter as active fuel management did. The rocker arm “lock pins” are used on overhead cam engines.
Thanks Sam
My 2021 Silverado 5.3 L engine with 10,000 km failed last Friday. Hell of a racket under the hood. Dealer/Shop says lifter issue. Played dumb on this being an inherent problem. Have been told it will be weeks until parts are available. Now I read here it is recurring after initial repair. I want my money back.
Absolutely right!!!! GM should be buying these P”SOS back that they turned out on to the public. This pisses me off that a so called AMERICAN COMPANY would do this to their patrons that I will seriously NEVER buy a GM product again. Their lack of empathy and their out right unwillingness to fix their own sh*t right is unbelievable. These are sad days for Americans when you can’t trust a Company like this anymore.
Damn that 0w20 tho
I bought a 2018 already replaced transmission at 130k and power steering at 150k. Power steering locks up and hard to steer spent $8000 since March. Called GM and they really did not give a dam about safety on the steering locking up
You made the mistake of buying a 2018.
Should of bought a 2000s truck instead.
My 2011 GMC Yukon XL Denali 6.2 V8 did the exact same thing this is nothing new. Got a 2001 gmc 1500 5.3 with 380,000 miles no issues. Leave it to GM to Mess a good thing up.
The 5.3 and it’s predecessor, the 4.8, are essentially 400k engines that GM ruined through the addition of AFM. I own an ’09 Avalanche with 350k miles that’s spent the last 4 years regularly towing a 7000lb 28ft camper. It 5.3L engine doesn’t use a drop of oil, has good compression on all cylinders and maintains good oil pressure even idling and hot. The transmission is also original and has never needed servicing – still the original tranny fluid.
The trick is disabling AFM as soon as you possibly can. I would be cautious of any used 5.3L AFM equiped truck with more than 50k miles. GM isn’t stupid and they do extensive endurance testing on everything. The were fully aware that adding AFM to these engines would reduce average engine life but testing indicated that the fraction that would likely fail during the warranty period was small enough that GMs overall liability was limited and easy offset by the gains in mileage and reduced emissions. They calculated that AFM equipped engines would last until the warranty expired at which point it would become the customer’s issue. If the problem happens to start showing up during the warranty period, just make them do a bunch of oil consumption tests to deflect blame long enough to pass 60k miles.
You don’t need to replace the lifters or make any mechanical changes to the actually engine to disable the AFM. Just get a handheld tuner and disable the 4 cylinder activation. Done.
The other critical things are using full synthetic at every oil change (6k miles between is fine), keep the oil screen behind the intake clear and opt for the factory HD transmission cooler or install a quality aftermarket cooler. A $50 transmission cooler will literally double your transmission life (easily). Also, then towing thru mountains in high heat, keep an eye on the transmission temperature reading on the info display. If the temp goes beyond 200F then back off a few MPH so it can catch up. If it gets to 215 then pull off at an exit and let it cool down for a bit.
Another important note on the automatic transmission – do not do any fluid flushes or change the tranny fluid despite what the quick change tech might be telling you. Engines are on open system that take in dirty fuel, dirty air and burn it which produces carbon and other byproducts that end up in the oil. An automatic trans is a CLOSED hydraulic system. It’s sealed. The only particles that can end up in the trans fluid are small particles from wear on the clutch packs and bands. As these components wear the particles suspended in the fluid begin to essentially function as friction modifiers that will keep the transmission components from slipping as they wear. Flushing the trans fluid removes these particles which makes a higher mileage transmission more likely to slip which increases heat in the transmission fluid and shorten it’s life considerably.
I’d also recommend avoiding E85 ethanol when fueling. Even on a flex fuel vehicle ethanol is harder on fuel system components than gas and its tends to absorb water which is not ideal
A lot of the 5.3’s in your 2009 era had consumption issues from ring failure.
I believe gm did something with a new ring design that was failing. Even the 2.4 I4’s with no afm were prone to failure back then.
This is BS. I have a 2009 Yukon XL I had to have the engine straight up replaced in. It is the 5.3L.
I now have a 2019 Sierra Denali Ultimate with the 6.2L and this is still an issue?
And to the person that said the new 6.2L doesn’t have AFM, you are not correct. It has DFM, which is the “new” version of AFM.
I wish GM would get their crap together!
Totally different system.
Afm used special lifters with two separate actuation valves in them. 1 was for the typical hydraulic lifter takeup, and the other allowed deactivation of valve.
The new 6.2 uses dfm or dynamic skip fire, which actuates at the rocker arm. the lifters are supposed to be standard lifters.
this is a much better system due to more flexibility. But the big difference for me is now if it does fail your changing a rocker arm by removing the valve cover instead of pulling your heads to replace bad lifters. A rocker arm is a pretty easy job that most people can do in the garage over a few beers.
Now the 5.3 is still being sold both ways. Afm and the newer dsm, dfm, skip fire, whatever it is.
A lot of misinformation it seems. I have a 2020 at4 with a 6.2. I am glad its a dfm and not the older afm just for user serviceability. But i prefer if i dont have to learn too much about it by working on it. Lol
Wrong, they use afm style lifters for all the cylinders. The rocker arms are standard. Oil pressure latches and unlatches the lifters. Just had 2019 6.2 apart.
Ok so the skip fire system apparently is using the lifters on ohv engines and the rocker arm pins are for ohc engines. Watching the videos of how it worked showed rocker deactivation.
I was really hoping these new engines got rid of the the lifter setup. Time to buy an extended warranty.
My 2021 Trail Boss with 9K miles has been sitting at my local midcoast Maine Chevy dealer lot with a collapsed lifter for almost two weeks. The service manager does not say when a lifter bank replacement might arrive. They’ve given me a reliable and fully equipped F150 loaner, and my wife says the Ford seats are much more comfortable. My first great GM ride was a ’70 Chevelle SS. We’ve had four reliable Tahoes over the last forty years, but this lifter mess is a real game changer.
Yes sir my friend 70 Chevelle ss now that a machine a real car ! With real power and you can beat on it all day and never brakes when gm made real cars and trucks !!
NEW Built in July 2021 Trail Boss /miles 1,849..In Shop Now LIFTER PROBLEMS..?VERY DISAPPOINTED
It is a JOKE. GM is a JOKE. I’m so pissed off at this company for letting these trucks even get to the market. This sh*t GM is producing now is comical. The only way GM fixes these issues is to replace management and start to have some pride again in what they build. This Company has dropped below the pass meter in anything their doing right now.
Was it a Mexico or US truck. Not sure that matters cuz I think all engines are US made. Thanks
My 2021 Trail Boss with 9K miles has been sitting with a collapsed lifter in my midcoast Maine Chevy dealer’s lot for almost two weeks. The service manager has not called me to say when a replacement lifter bank might be available. I’m driving their fully equipped and well appointed Ford Sport 4×4 Ecoboost dealer loaner. It’s a very nice truck. My wife says the seats in the Ford are much more comfortable. My first GM ride was the fantastic ’70 Chevelle SS, 454 LS5, red on red with black dorsal stripes. Over the last 40 years we’ve owned five reliable Tahoes including our current 2018 LT. This 2021 5.3 liter lifter mess is a game changer. I’m just wondering how many hours away from the nearest tow truck in remote northern Maine I’ll be when another lifter collapses.
2021 1500 Silverado, 6.2. 7600 miles , letters just went. Dealer says they are going to replace both sides. Had the oil changed at 3800 miles. Was just getting ready to do it again. My son and buddy both have 2017 Silverado’s. Trans shutter on both. My sons has now been in 4 times for. I’ve owned GM for over 50 years. I’m done!!! Should have my 2012 Silverado with the 5.3. My father was a mechanic so I was involved and a good friend of mine has his on garage. I can count on one hand how many lifters the three of us replaced in over 50 years and trust me the ones that were done has in excess of 80k miles on them. This is pathetic
Only major difference in DFM, outside of the ability to kill up to 6 cylinders independently is the the dropped the oil manifold from the AFM system for the sake of 8 individual oil solenoids to control the lifters. DFM still uses the AFM style “spring” lifters, they may be redesigned, but the concept is effectively the same.
I had the same issue with my 2014 6.2L. One of the problems is the use of the 0w20 oil, it becomes way too thin to protect everything. Need to use a thicker oil 0w30 or even 0w40 will have better protection. Plus also best to have the entire bank replaced if one of them goes.
Actually I’d do what I’ve done in my 2017 Hemi Ram, go to 5W30 and ALWAYS use synthetic oil!
I own a shop and can tell you all its the DOD that is the issue, can’t have cylinders not firing and not expect issues, have dealt with this on many Chevy trucks since they started this. Only fix is to get rid of the DOD with new cam, lifters, and push rods, then you have to get a programmer and shut that system down in the pcm or it will screw up the pcm. Big fail on GM for this
The problems are mostly supplier issues.
Many companies compete and low bid wins and this can often lead to issues.
GM is far from the only one with supplier issues.
Another issue is GM is one of few still using this type of push rods and lifters as most have moved on to OHC.
I bought a 2021 Chevy Silverado in December of 2020 and been in service garage 3 times in 6 months 2 times it was for bent lifters all 8 each side and a bent push rod and the other was a broken strut on front .Brand new truck what the heck .But got it fixed hopefully nothing else happens to it I would love we to b Wed able to enjoy my truck and not worry about breaking down.
I guess I have been very lucky. I have read about all the problems people have had with their GM trucks over various years. From excessive oil consumption issues, brakes, piston slap, and now lifter/valve train noise or lifter collapse/ spring failure. I’ve personally owned over the last 15 years a 00 yukon 5.3, 00 camaro LS1 5.7, 02 yukon XL 5.3, 06 1500 Z71 5.3, 2014 1500 Z71 5.3, and purchased new in 18 a new 19 trail boss Z71 with once again 5.3. And my wife’s 2011 Tahoe 5.3. Last 2 were purchased new. Made in Indiana plant, union made.. All of which were used for use to and from work at both highway and in town driving daily 5-7 days a week, 50 miles round trip and loads of family trips, hauling car trailers loaded. I do all my own oil changes and service, with the exception of service bulletin recalls. I have NEVER experienced any of these issues, and all of the vehicles(except my 11 and 19) were bought used from a very reputable dealer with anywhere from 33-60,000 miles, except the yukon, it had 220,000 when purchased for some long trips. All vehicles were kept and driven with an average of 70-80,000 miles put on them before sold/traded in. With exception of the 11 Tahoe, it’s got 160,000 on it and my Trail boss now has 39,000 on it. Both bought new. And 0 issues that all these recalls or problems that are being reported. So, I either have VERY good luck. OR it’s because they were all serviced when they were supposed to be. Very loyal GM customer. I bought a 04 dodge ram 5.7 hemi crew cab new in 04, never touched it other than put gas in and check the oil. All services were done on time AT THE DEALER by them. 1 year, almost to the date, with less than 24,000 miles, I was interstate driving at 80 and the engine sucked a valve in and I was left without a vehicle for 2 months, because they had to send the engine to Detroit to determine if it was my fault or theirs, see prior statement about service done on it. They deemed it their fault. But I was out a vehicle for 2 months, and had to buy another to get to work (00 yukon). I sold that pile of dodge. GM for me. Forever!
Sure hope our 2016 Suburban has the 3.5. Has over 142.000 miles, I have the chip you can plug into the Ob2 to over ride the Afm. When I saw this killing the motors
Chevy lost the court case for all 2014 5.3 engines as the engine is faulty and is built to break. 2015 and newer is still waiting for the proper evidence and car history to win the case. Look up class action lawsuit for info. My hopes are that Chevy will replace My engine with a crate motor or at least a real V8 that only runs on all 8 cylinders. I have taken my truck in twice for the lifter on the driver side against the firewall. Both times they refused to change my cam saying it showed no damage but my lifter blew.
First of all, what normal person drives a v-8 today…knowing that you are decimating the planet. Then, also, the idea that countries besides america make inferior products is such ignorance. Last time I checked, americans used the toilet just as much as any other country!!!!!
I’m sure the extremely toxic battery’s used in electric cars and hybrids are the answer right?
I’m picking up my 2021 elevation Monday…wish me luck
My 2007 Silverado classic with a 4.8 liter V8 dropped a lifter around 90k miles. I changed the oil & filter myself every 3000 miles and have the records to prove it. I suspect it was a result of a hard misfire during a downshift while passing another car back at the 38k mile mark. I found the pieces of the roller part of the roller lifter in the oil pan. Thanks gm.
So these are two different issues. One recently with a bad batch of parts…OK, I get that, it happens. The other is with a crappy design that goes back to AFM and now DFM since before at least 2009.
My wife has a 2009 Yukon XL that we had the engine replaced. Yeah, it was long in mileage at around 200k miles when it happened, but it is a regular occurrence with these 5.3L engines with AFM. I also have a 2019 GNC Denali with the 6.2L, around 33k miles now. I am looking at getting the AFM/DFM delete for both. Apparently this keeps the design flaw with the lifters from happening.
Anyone have any experience with this?
I have been looking at the Pulsar LT for my truck and the OBDII module to deactivate the AFM on the Yukon…
Not sure about the dfm delete. I would think it would be as simple as the $200 obd plug you can get for afm.
They actuate very differently though and am not sure it would provide the same benefit. One allows the lifter to decompress while the other actuates a rocker arm. I have not seen a good explanation of how the rocker arm actuates yet.
My 2010 yukon denali 6.2 l had the same problem, not only was I pissed because I barely drive it , had 96,000 after 3 years of purchase I have 104,000 , The mechanic charged 3,200 to fix it ! They said then it was a common problem with these engines! Made as hell!
Never received a service bulletin. No problems yet.
Yep,
My 2021 Yukon Denali, 12,000 miles just spent 5 days at the dealership getting new lifters and pushrods after this happened. Love the vehicle but this shouldn’t be happening.
Dealer was great and got right on it.
I really hate to tell them this but it’s been a problem from the introduction of the ls style motor. I’ve seen several come through my shop with lifter issues, mostly 5.3. The problem is its not an easy fix as in most engines. The ls requires the heads to be removed to change lifters
Go back to the LS motor the LT sucks I work on them evey day
Gmc….never again as I spent months and approximately 15% of all miles on my 2009 5.3 going for warranty as the closest dealer was over a 100 miles away. Had a loaner car for over three months while truck was getting repaired. Lifters, rocker arms a and push rods were bent and replaced as well as the piston ring gaps were lined up on most cylinders. Oil consumption was terrible losing two liters minimum between changes. Motor was gummed up producing horrible fuel milage. Fixed it good….bought a tundra that I checked oil on yesterday after 10000 klms the oil has gone down nothing. The Toyota does everything better including fuel milage. Never going back to GM as I believe they are pure junk
To each their own.
But I will challenge you on the tundra mileage. Old tech motor that consistently is the worst in the full size trucks. They aren’t real popular around here but the one guy i know that has one never gets over 18 and admits its a gas hog.
I get over 20 in my daily commute of mixed city/highway in a 6.2/10 speed. I have seen up to 24 on long steady runs. Toyota has a lot of long in the tooth drivetrains in both their trucks and even the loyal owners i talk to wish it was better.
Great info on recent posts! Was unsure before your post if I should just disable AFM or had read somewhere folks change the AFM lifters and cam to mechanically disable AFM which doesn’t seem required after this read. Also good to know on tranny flush, had a Bonneville in 90’s that suffered transmission issue/slipping immediately after GM service center flush. Have seen charts where transmission temp directly proportional to transmission life, mine hovers between 185-200 once on the road over an hour, will look into tranny cooler.
My 2015 GMC 5.3L suffered failed lifer/bent pushrod at 5.5 years, 72K miles, Point being it’s not just the most recent iteration of 5.3L and many from my era truck have failed. I’ve witnessed no oil consumption before or after repair. Will definitely skip AFM in next truck and look for DFM so perhaps 6.2L next.
I am having the same problem with my 2008 Chevy Silverado LT 4.8
I am having the same problem with my 2008 Chevy Silverado LT 4.8L motor
Wow reading all these comments about lifter and valve spring problems do I really want to buy a gm but I’m sure ford and Chyrsler have there issues also . Was thinking of buying a 2022 Terrain denali with the 1.5 engine I know it’s not a v 8 but hope I don’t have these kind of issues when I buy it maybe might have to re think !!!
When you sell millions of one motor your going to have issues.
The afm issue is real but between maintenance and bad luck its not as rampant as forums like this make you believe.
Dodge seems to have cam problems on the hemi and Ford has known issues with the ecoboost and the 5.0 over the years. Toyotas had unacceptable frame rot problems.
Point is most vehicles well maintained provide pretty good life. People forget how bad engines were in the 80’s and before and they were incredibly simple. Sometimes you do everything right and still get burned. So Its good to research but by and large most of these issues don’t affect the vast majority of trucks.
Wow reading all these comments about lifter and valve spring problems do I really want to buy a gm but I’m sure ford and Chyrsler have there issues also
I am on my third Silverado, keeping each one over 10 years (current one is at 9 years). Quality has been excellent, but what has amazed me the most has been the support from the dealership and / or GM when there was an issue. They always went over and above my high expectations.
I have two friends who own 5.3L 2020 Silverado’s. Both have had this lifter issue (one while driving out of the dealership lot – brand new). The other on a cross country trip with his wife with 9000 miles on it. This happened a month ago (long after the “service bulletin”. When he called the dealership they referred him to gm’s 800 emergency number. What a joke! I am sure no one at the top of gm has ever called this number. They were stuck on the side of the road in a $55,000 vehicle and the automated line of the emergency number tells you to get the app!! After multiple prompts, could never get a human. On a call back they ordered a wrecker. It never came. (new to gm they never thought to use the emergency On Star – which the dealer never mentioned!)
At the dealer they replaced ONE spark plug to fix; Engine noise, Service Emergency Brake IL (idiot light), Service ESC IL, Traction Control IL, Stability Control IL. That worked for about a half a mile, then back to the dealer who then replaced the lifters. gm needs to inform owners of this issue NOW!!
I guess the new gm stands for “going mediocre”.
Just did a engine ( on my dime )replacement in my 2010 escalade 6.2 engine 71,000 miles synthetic oil change every 5,000 miles never missed. Low compression cylinder 8 misfire. This is not a new problem for gm
Your in that vintage where rings were an issue. My brother in law had a 2009 with bad rings. The afm was good for years but the truck burned oil heavily when towing.
I think he also had a stuck afm lifter recently but it was years after the ring issue and he’s probably the worst person I know for vehicle maintenance.
Pulling the head for lifters sucks. The old gm v8’s only needed the intake removed.
Put a woman in charge of a company that builds mechanical things and things like this are a givin…..
We make the lifters in gr mi. We had some produced with the clip groove cut to deep.
This makes sense.
If the lifters are failing on new trucks with dfm and not afm its a manufacturing defect of the new lifter.
Sucks for sure but not related to afm lifter failure
Geeeeez, a familiar all too frequent occurrence in the gm production process. Perhaps they need permanent QC vs some temp. These parts should never have been inside an engine period.
Just happened to my brother’s in law Silverado 1500 6.2 – 2 weeks ago, my service department got it fixed in 2 days. he had 6200 miles, my truck currently has 8300 miles, 21 6.2 as well and i’m just waiting for it to happen :/
I have been a Master certified technician for over 40 years.This is not a new issue with these lifters.GM has had this problem with Active Fuel Management lifters since they have this system was designed all though it happens much more frequently on the 2021 5.3 and 6.2.most are failing with under 10000 miles. This is definitely a prime example of the GM way of finding the cheapest manufacturer and changing the most for there products. In order To save even more money they cut the labor times on the repairs to the dealership and technicians.
I’m a ASE certified mechanic.. Very dissatisfied with GM.. People pay top Dollar for their vehicles. Though I do recommend full synthetic oil always and change it every 3000 miles. In addition always check the oil level once a week.. BG product MOA Engine oil supplement will unbelievably help! I know for a fact. I am honest and really care about the consumer..
Damn brake lines are common to fail on all makes.did u fix biodegradable leaf spring shackle.cheap speakers.cheap galvanized steel.wiring harness that goes bad when u put ac full blast. Cheap keyless controllers that go bad. did u forget to put real steel bumpers and a fully boxed framed on a silverado.u been having weak cilinder heads since the 90s,upgrade your cylinder heads or I’m getting a tundra.your chevy employee stole my GMC I demand a full refund chevy
Typical of American cars. Quality isn’t there and failures abound
I have Hondas and GM’s in my driveway. I could give you a laundry list of how far they’ve gone down since the early 2000’s. Quality is down but complexity is up.
The old crv’s were bullet proof. Cant speak highly of the last 10 years
Nothing new GM has had lifter troubles on 5.3 even in 2000s model trucks mine lost a lifter at 100000 miles 2008 avalanche with a 5.3
There’s a lifter bulletin for builds between Sept 20′ – March 21′
I can’t remember the “hot rod show” on cable. I think it was “Texas Metal”, but not sure. I remember they were putting in a super charger to give it a couple hundred horse power. I remember them putting in a new cam and changing out the lifters because GM was having a lot of trouble with them in the 6.2. They were doing away with the active fuel management. They said something about no oil to the cylinders that were shut down. That’s when I shook my head and was glad I have a 2012 with no AFM. I then wondered on how big of problem it was.
My truck failed in the 1st week of June 2021 with 7000 miles on it I purchased it with 3400 on it in March. My coworker failed 2 weeks before mine with just over 5,000 miles on his.
2001 chevy suburban with the 5.3 just started the lifter noise at 387 k is their a recall on this ?
This issue did not just start, it’s been going on since 2006 in all the 5.3’s and 6.0 an 6.2 engines. Pretending this is a new issue is asinine. Noisy lifters and failing lifters have been on YouTube for years even happens in well maintained trucks.
But it does seem like a different issue from the afm lifter. This sounds like they were improperly manufactured. Two different issues same unfortunate result.
ICE will do themselves in and EVs will replace without government intervention. So stay away Washington!
There’s a reason chevy doesn’t build heavy duty any more. Just get a ford. Problem solved.
Because ecoboosts are the pinnacle of problem free operation?
Why did Ford never use ecoboosts in hd trucks and now has gone back to ohv engines?
My 1999 1500 Silverado z71 4×4 5.3 LS engine is just about to click 300k…runs like a clock…quiet as a first Gen electric car…..transmissions need to be better designed…rebuilt this one 4L60e…but went with corvette servos…but power is plentiful and don’t have a care in the world (well maybe DA drivers texting and etc) but definitely dependable and this 5.3 has 55psi idle and 60+ driving oil pressure!! Royal Purple oil and white K&N oil filter
My 2021 Tahoe has this issue at the dealer for over 2 weeks and all i get from head office is smoke and mirrors. Tahoe has 9000km very upset as i ghought i was buying a solid car but i guess not.
2021 Tahoe with 9000km in the dealer over 2 weeks before that paint was an isssue not polished or painted from factory and now this lifter issue geez had my Tahoe for four months and cant even enjoy the vehicle its been at the dealer more times then any of my vehicles . So sad to get the run around to from gm here in Canada will be trading this garbage in .
Bought a brand new 2020 GMC X31. Lifter failed bent pushrod and broke the rocker arm in two. This happened with less than 11,000 miles. Can’t say I was happy with that but apparently this is happening a lot because the dealer knew exactly what it was and they had the truck repaired in three days.
My 2010 Sierra started burning oil at 55,000. 1 qt every 1,000 miles. Dealer rebuilt engine after stringing me along for 20,000 more miles. Transmission started hard shifting at 25,000 and they couldn’t find the problem. Engine crapped out at 100,000. Lifters broke on the interstate. Traded in for 2021 4Runner for the wife and I bought a 2014 Ford F150 from my neighbor. My family has always owned nothing but GM. Never again. Now my father’s 2017 Silverado with 25,000 miles shifts hard and dealer can’t find the problem. Sad state of affairs.
I knew there was a problem when my 2011 gmc had lifter problems on the center of the right bank. I could order in half a engine gasket set. When I got it apart the oil was being filtered to the center lifters, and the little phoney filters they had in there was clogged it ticked me right off. My oil was always changed at the dealer and on schedule. That was at 190000 miles cost me a lot of $$$
This is an issue similar to what the 6.0 is having!.
The dod system acts up in the 6 0 and usually its on the even side.
The lifter squats and doesn’t pump back up.
If they would quit using plastic lifter guides they wouldn’t have this problem. The problem lies is the engineering of their engines. When these fail it requires a complete teardown of the engine down to the cylinder block, and sometimes replacement of the camshaft due to the lifter turning sideways causing damage to the camshaft lobes. It’s really simple use metal parts instead of plastic, and provide the consumers a better product.
(#1)My 85 El Camino was built in Mexico, sticker on door jam. I had it for 20 years. Drove it every day! Never had a problem.
(#2) Supplier problem with my C7 Grand Sport wheels. Fragile pieces of crap! Made in Taiwan, designed by idiots at GM. THOUSANDS OF WHEELS WARPED AND CRACKED UNDER NORMAL DRIVING CONDITIONS. GM not standing behind these.
So very sad parts from Mexico fall below expectations friends. While quality is important, perhaps corporate corruption on both sides of the fence causes issues in manufacturing because labor does not wish to be a problem. Out of control Cartel from American gun running operations (Fast and Furious) that go bad and leave over 20,000 automatic weapons in the hands of the Cartel might be a clue perhaps. Thank you Obama for that.
Wow! Time for your meds and a new Tin Foil Hat!
You’re an idiot. And your racism is only partly to blame.
I have a 2016 GMC Sierra 4×4 with 5.3l with 47,000 miles. Does this valve issue apply to my truck?
My 2009 Silverado 5.3 did the same thing.
Cost me 3800 bucks to have fixed and then 7k miles later the motor started leaking antifreeze into the motor. Motor locked up and I was passed my repair warranty by 1k miles. Pissed off is an understatement
Likely built exactly to GM specs and no difference where the parts were manufactured. Trying to shave half an ounce from the vehicle weight.
Thats why ford is a better truck.
Yep. The warped dashboard in f150’s since 2004 thats never been repaired speaks directly to your comment….
Sorry no Beer Can Fords for me! I want to Ram in 2017 and never looked back. I know they have had lifter issues in the Hemi as well but they provided something GM or Ford didn’t, a Maxcare lifetime warranty with $100 deductible.
And then why is it that Ford had to buy back so damned many 07 turbo diesel trucks? AND….. Another friend spent months waiting for his 2018 Ford Truck transmission to be fixed.
My husband had this issue on his ’21 GMC Sierra 3 different times in a period of 2.5 mos. It all started when he only had the vehicle 3 mos. We opened a case with GM. The dealership ended up trading him for another truck.
I just had an issue with this on my 2015 Silverado High Country with 90k miles and the chevy mechanic said I would be better off replacing the engine. He said the cost difference in replacing the parts and labor would be close to just putting a new engine in. Took almost 5 weeks and $7800. Just over 90k miles. Out of warranty. I had to pay all of it out of pocket. No help from GM. Very disappointed.
This seems to be a different issue from what you had with the afm trucks. Different lifter issue.
If I was going to all that trouble I would make sure I put non-AFM cam and lifters into it and disable the system.
GM junk
Have a 2009 GMC 1500 with the 5.3 had to have the left side all all the lifters replaced due to failure which was about $7000 at this shop And I understand I’m just one of thousands who have a crappy engine from G I’m Jim this week my brother-in-law had called me about the noise in his engine and by the time He started to tear it down to check He had the number 2 pistons on the passenger sthe passenger side disintegrate he has the 6.2 and a 2011 GMC U con it’s the Yukon what a disgrace to GM not replacing these engines for free it’s for free and making them the vehicles that they used to be
These people commenting do not know anything about anything. Lets atleast get one thing straight for the uninformed to put it nicely. American vehicles has not had anything really American about it since around the 70s when engineering and designs were traded and bought out by different companies for various motors and transmission designs. Like Volkswagen designing a motor for ford and stamping ford on the engine block only because it was made in a ford manufacturing plant. You guys are really just geniuses. Go look it up yourself.
Agree. It would be nice for this comment section to offer some input for people looking for answers while not turning into the usual “scary mary” “ my truck is better because my old truck broke” tired routines.
Most modern vehicles are sourced similarly and execution is more important than the sum of the parts or where they are made. The lifter issue needs to be addressed well by gm even if the old afm issue is different than this issue.
Bad thing is us die hard GM guys and gals. Will end up leaving GM. I guess they don’t care till they end up on the street!!!!!
If you didn’t leave in the 80’s, why would you leave now?
😂
I lived through the GM vehicles of the 70’s and 80’s and one thing that WAS reliable through all of that was V8 engines. Like my 75 GM Beauville van that I finally sold off in the early 2000’s with over 350K miles on it and that 350 SBC was going strong and didn’t use a drop of oil.
My 2004 Z71 had a lifter problem at 150K or so, my 2011 Tahoe had a collapsed lifter at 95K. I always buy 100K warranty. My 2020 has a warranty to 150K and I hope I have no major issues by then.
It started in 2007 1\2 and there only going to fix newer ones really wtf chevy has know about this problem for years and years
Oops. It was my 2016 that dropped a lifter at 95K. My 2011 went solid to 165K before I traded it for the 2015.
Just traded the 2015 w/ 126K for a 2020 in Feb.
Sorry for the mistake in my post.
This is my 6th and I don’t know if I’m coming back, but they are darned good looking vehicles.
Maybe, buy the 150K mikes warranty from now on.
2015 silverado 5.3 with 96K on it and the lifters failed! This is a problem that GM has known about for a long time. A V8 that can’t make it to a hundred K without a rebuild is crap. This is a black eye for the north American auto industry. $9000 for a rebuild and AFM delete kit. I’ll never buy GM again. And they wonder why people are not buying American, it’s because we’re tired of being treated like fools for buying trash. The big 3 are pitiful examples of mismanagement but GM is the worst by far. It’s too bad that so many employees will go down with them
GM production of junk, 08 Chevy Colorado engine went out 2.9L engine . Dam junk. You cannot stay in benefit from half ass production, I will never buy. GM never again .
Why I wouldn’t own one. When the engine in ones new $40k-$70k truck has to be torn down and has parts failure and debris in it before the first oil change, that engine should be replaced.
When the lifters collapse going down the highway and the engine will no doubt have wear and debris in it leading to more damage and wear.
I’ve been ase certified for over 25 years and I would not want just anybody tearing down my “new” engine/truck.

All GM 5.3 after 2005 are junk
Have a 2011 6 2L SC Cadillac CTS-V with 55k miles. After a small rev, it Suddenly developed a misfire and started smoking (whitish). Thought I blew the motor or poston or something. Ended up one of the intake pushrods Broke! Not bent, broke. Thankfully a new set of hardened pushrods fixed it with no other damage. Lucky I guess!…but that shouldn’t of happened IMO.
It is not that it is timing Chain Guide That break off And go to the oil pick up tube Dodge has that issue too
Have a 2021 suburban, bent push rod at 5,000 miles. Lost faith in GM
I purchased a 2015 chevy Silverado brand new,and the chevy dealership did all my oil changes ,at 54,000 miles my truck had,this,problem ,they fixed it with no cost out of my pocket, also before that at 40 plus thousand miles my ac went out my extended warranty had to pay for that I goggle this problem and yes all gm product had this same problem I checked my purchased order and my truck was made in mexico
Actually in my experience the Mexico trucks seem to be better than the US ones.
Considering the parts are made in the same place I’d say you’re more than likely incorrect. My Ft Wayne Truck is a well made truck excepting the window regulators (3 failed) under 55k miles with minimal use. One dash cracked all to hell, (China) and the chrome cladding on the wheels cracked early on with less than 10k miles. Not exactly an assembly line issue. Oh, and the plastic trim on the sides of the wiper exterior. (China)
Oh, and the quickly oxidized plastic headlight lenses. More China. The drivetrain has been very good so far.
2019 Silverado 5.3L – I experienced this exact issue at about 16K miles. Dealership kept it a week or so to replace the parts. I was hoping this wasn’t gonna be the norm for a new GM owner. Since repairs, I’m at 34K with no issues.
My wife has a 16’ 5.3 Silverado never treats it nice oil changes late ? She now has 84k miles runs mint , does burn oil tho. I have s 02’ HD 6.0 200k awesome truck. I also have a 13’ GMC HD 6.0 motor is awesome obviously no cylinder deactivation, i will say my 02’ i feel has better quality than my 02’ in many ways tho?
Will GM say again that this is a design flaw not a manufacturing flaw, and not cover it.
Happened on my 2014 Silverado. Cylinder 3 failure. Replaced both sides under warranty(I bought when I purchased the truck at 37k miles). Saved me the $5000 bill. Also had the a/c replaced under the same warranty. Saved me $1500. Warranty was only 3k.
My 2021 5.3L Trail Boss had to have the the lifters replaced at 9k miles. Took them 3 weeks to get it finished. It seems to be fine now.
Wonderful! I have one of these trucks. God help me when the warranty runs out. GM has no concern for durability.
I was wondering when I had the opportunity to talk about the valve lifter issues. I had a 2015 Silverado, it just got to 101,000 miles and the lifter gave out. Passed the warranty. Paid about 11,000 all together because a month later. Another lifter gave out. I had no issue with my 2006 Silverado, other than the driving gear on my tranny was starting to wear. Last odometer on that truck was 492,000. Chevy needs to fix the issues right away.
AFM or DOD or whatever – have 3 trucks all with the same issue due to the complex and stupid design. Replace the camshaft, all the lifters and valley pan, disable the software, and now the engine is solid. $600 in parts and about 6 hours under the hood, and never saw a damn bit of difference in mileage. It’s smoke and mirrors. Time to eliminate CARB
I did exactly the same thing on my 2014 5.3 Silverado – AFM Delete. Replaced all parts and shut off DoD in the Module. Who the hell buys a V8 to ride around on 4 cylinders anyway?! As for gas mileage, I get better mpg now with a 91 Octane tune.
Talk about not making them like they used to, I have a 1971 Camaro in my garage that is all original drivetrain from the factory including the points and condenser ignition system. It still starts and runs pretty good for being 50 years old.
The lifter issue is directly related to GM’s Active Fuel Management system and has been an issue since the very beginning. I did an AFM delete on my 2014 5.3 Siverado, replaced all the lifters, valley cover, oil pump etc and have had zero issues ever since.
I have a 2001 Silverado with a 5.3L. It has the lifter tick also. It had 252000 miles on it when the oil pump went out. Hopefully a new pump will solve the oil pressure issue but i think it will end up needing an engine rebuild or replacement.
Mary Barra and GM is more concerned about being woke and ridding the company of systemic racism and global warming than they are in producing a quality product. Headed towards bankruptcy pt. 2.
Installed afm disarm in my 2010 5.3
185k no problem so far. If you wanted fuel milage buy a civic….
Who keeps coming over here,
When our jobs go over there, we fear?
If jobs they do better in another place,
Whence cometh job seekers at a rapid pace?
One Says: ” I seek my replacement part!”
Another says: “NO! You have a hateful heart!”
One whose work is in quality, peak,
should not have to travel , employment to seek.
Why do we build our companies,
in places that others choose to flee?
To this country they must come,
to seek employment given to some,
Who do fine work and do it well,
A better product for to sell!
If so, why journey to another sphere,
When they keep coming over here?
Why not just admit them to the guild,
instead of foreign factories to build?
Is it not true, human beings that we are,
Have hitched our wagons to a golden star?
In our human hearts so weak,
Large sums of money do we not seek?
If it is true that we are all the same,
– Who, then, really is to blame?
Walk street abs Washington DC.
Ok guys. Seems to have quite a bit of experienced ‘5.3’ Vortec engine skeptics here. My 2020 Premier has 27K miles abs I sprang for a CNA 150K power train warranty. Should I ride it out or what steps should I take to avoid the lifter/ Cam shaft issue?
Will probably do 150K in 6 years.
Yeah my 08 4.8 has the same issue nothing new
Mexico has nothing to do with it these variable valve timing engines with active fuel management are designed by Young Engineers that have no real-world experience it looks good on a computer so they make it
The cost of those kinds of engine repairs will surely hurt their profit margins. My son-in-law was always a GM only guy until he bought a Chevy 2020 SUV. It was recalled every month for the first 3 months he bought it. It was garage kept. Well the last time the dealer had it, it sat for a few days on the lot. A storm came through and it suffered hail damage. Its not just L84 and L87 engine problems with vehicles made in Mexico.
I own a 2012 silverado. Bought the afm plug in delete to avoid any more issues. A quart of oil dissappered once along with the noisy lifters when afm kicked in. Hope this saves my motor
This is possibly the most poorly written gmauthority.com article ever written. What was supposed to be a piece about the significant issue GM trucks and SUV’s with the 5.3 L. and 6.2 L. V8 engines are experiencing with collapsed hydraulic valve lifters quickly devolved into a re-hash discussion of a completely unrelated problem with broken valve springs. If there is a technical editor reviewing these articles before they are posted, that person needs to up their game.
Please refresh this article with a focus on the collapsed valve lifter issue.
IMHO EPA standards are ruining everything. Care for the environment, of course, but at the cost of not having the equipment work. I’m not sure how smart that thinking is 🤔
Same thing with refrigerators, washing machines, dryers, etc. Nothing works anymore.
Makes me wonder how much of the environment we are “saving” with all the necessary repairs and junk pile of parts.
Thanks for the info. My 15 tahoe experienced a collapsed lifter. The dealership replaced an 1 week later the same valve collapsed an this time seized in the engine block. I fought for 5 weeks with them an GM an the engine had to be replaced an GM was only giving $1000 towards the new engine since I had 108000 miles on it. So alot of money later I have a new engine with a warranty now. GM didn’t care that I have driven Nothing but gm all my life
What’s the point in just doing one side? Need to replace both sides. GM attitude and philosophy
GM has had lifter issues for almost 15 years, I’ve replaced dozens of vehicles lifters as has every GM mechanic. The new direct injecting stuff is just worse still with valve spring defects. We’ve had engines with 5-35k miles breaking springs. They are garbage. You want reliable buy a lower mileage truck that didn’t have cylinder deactivation from mid 2000s, they will go 500k no problem if you change the oil.
This is why my dealer used, my paid warranty . Lifters failed spring…. Cost 5k…. Even had nerve to try to collect 1k….cause Warr… Wasn’t having it…. Sad….. GMC….. Why is this hard for you, to try…..my kid can make a better 6.2 build…… So, sad
My 2021 Silverado is sitting at a dealership in Arizona right now for the collapsed lifter and bent pushrod issue. They state all parts are on back order. I am just sitting here waiting for the 30 day mark to roll around so I can start lemon law action against chevy.
Where do I begin regarding this nightmare!!! We purchased his brand new 2021 GMC Sierra 1500 Crew Cab back in January of this year and have enjoyed every minute of it up until the second week in July! We took our normal family vacation trip down to Orlando Florida and drove our new truck, which didn’t give us any problems heading down to Orlando but the day before we were scheduled to come back to Georgia the truck began to make knocking/clicking sounds while we were out shopping. The knocking/clicking grew louder and louder as we were trying to make it back to our vacation home. We had no idea what was going on because this is a brand new truck!!! We began to smell rubber burning also and could feel pulling from underneath the truck as well. We immediately started googling 2021 GMC Sierra issues once we made it back to the vacation home to see if there had been any recalls on the trucks and found information about the lifter and some other things going wrong with these trucks. I have never seen my husband so upset in my life because he’d spent so much money on this truck and for it to be having these issues was just mind blowing to him. We tried reaching out to any GM dealer in Orlando that we could find but they all said that they could not get the truck in to look at it and they didn’t have any loaner vehicles, because there was no way we would be safe driving the truck back to Georgia. We were now to be stranded in Orlando. Our anxiety was through the roof!!! Fast forward to present day, where is our truck??? We were able to get the truck back to Georgia and to the GM dealership for repairs on July 9 and our truck is still with the GM dealer waiting for the lifter parts and bolts to come in, which have been on back order !!!! This has been a complete nightmare for us because had it not been for a family friend loaning us their vehicle to get back and forth to work, we would still be without transportation because the parts still haven’t arrived!! Oh and they don’t have any loaner vehicles available either!! I mean this is a brand new freaking truck worth over $70000, so for it to put us down in the middle of our vacation is just unacceptable!! I don’t know who we can reach out to about this but this is completely unacceptable and has caused us all types of stress and not to mention, we are still having to pay for a truck that we don’t even have in our possession!!!
Bought 2021 Silverado LT owned for 2 months exactly. Driving to SF from LA – 6 hr drive in the 3rd hour something in engine broke, waited 2 hrs for tow to Delano dealership. Said they think lifters are broken. I don’t want to drive a new truck with bandaid. Hoping Chevy will replace the whole truck. I should not have to fight about this issue.
WOW! Lot’s of 2021’s going down early. It’s a lucky thing i bought that 150K extended warranty for the power train. When the lifter in my 2015 collapsed, i thought it was something i did. All (6) my Tahoe’s were serviced by the dealer. My 1996 and 1999 both had the 5.7 engine but the 2004 onward had the 5.3. Each one of them (5.3’s) had something that went wrong in the engine but i always got lucky with the extended warranty.
Can’t wait till my 2021 trail boss is fixed, so I can dump it, my heart aches but I’ll never trust a chevy again🤔
How do you find out if my 5.3 is one effected ?? I have a 2015 and the motor had a short block change after 85000kms. It was changed in 2019 and I wouldn’t know what year it would be classified as
8 months in….. Lifter failure on a 2021…….POS!!
its the dod system you can’t shut cylinders down and expect them to work right. I have seen it on several GM trucks, you have to do a dod delete and the truck will be fine
This discussion has been very helpful for the most part. A few posts went off the rail. Anyway, for a guy that had 6 Tahoes from 1996-2020, I’m glad I purchased the extended warranty on my 2020 up to 150K miles. (CNA Insurance thru dealer). GM has messed up a good thing. I’m looking for my next truck but starting to look other places. Nothing out there compared with a GM Tahoe/Yukon. If not for this engine issue.
My 2020 Sierra is back in the shop for the second time with lifter failure in under 30k miles. GM won’t make it right, won’t even get me a rental car. Just wanted to throw my experience out there to hopefully warn any unsuspecting rubes like me from buying one of these born to fail pieces of crap.
I think some people here just making shit up. They probably drive a Ford or Dodge.
Not me I am driving a crap mini van and can’t use my truck. I don’t trust the engine from here. 3500 miles and mine died.
No unfortunately they are not been i Chevy guy my whole life and I got an 80k $$ boat anchor I can’t trust to keep my wife and child off the side of the road. I will not drive a Ford truck period all my work trucks have been dodges and they are not a Chevy. But what did GM expect to happen when you buy cheap parts and then cut the oil off to them while they are moving fast and hot. I’m not an engineer but if it looks a duck….
Has anyone received an extended (100k mile) warranty after this repair and did you have to go through GM directly or did the selling dealer handle it? I feel like I’m getting a little run around.
They are trying to offer that to me. Thing is I already got one due to the electronics. And it does not solve the main issue. I can’t trust it a warranty might fix it but it’s not gonna keep my wife and child off side of road. In harms way that’s dangerous. I didn’t buy it to worry. And I don’t feel safe driving it a large difference.
My 2021, purchased in Dec 2020 just went in the shop at 6,000K. All lifters need to be replaced. Started to misfire, loud knocks, loss of power, multiple warning lights came on. Definitely don’t expect something like this on a new engine.

My 2021 Silverado truck with less than 4000 miles has been sitting at the dealership since July 15 for this issue as lifters are on back order. As a lease vehicle driver what is Chevy going to do to keep its customers?.Paying on a truckI don’t have.
Just had my 1st Lifter Issue with my 2021 Suburban Z71 at 5,300 miles. Took 2 weeks in shop for parts and repair. 36 hours later, Check Engine light and same Error Code comes up while driving. I’m reading more and more about the Lifter Issues. Unreal. 1st new car in over 10 years and the new Z71 has been in the shop 3 separate times.
My first adventure was the passenger side. Second was driver side. Tech told me that they should have all been replaced but GM won’t do all 16 unless codes are for both sides. What a waste of my time.
First time I was stuck 3.5 hrs from home and they repaired in two days. Now parts are in back order for 2-3 weeks.
Gm is fixing them but I didn’t pay 80k for a vehicle that has to have engine opened up at 6700 miles for #8 lifter. It got lifters, trays, and pushrods. Waited 5 months to get it after we ordered it. Dealer fixed it but now it shakes and has the ticking noise on opposite side as failure. It’s embarrassing. It sounds like crap. I can’t trust it to not break down, and it cost as much as a house. They are not the only ones with issues my service truck is a ram 5500 Cummins and at 8000 miles had to pull after treatment. Intake was spotted up. Apparently the air box actuator was broke from factory. So it couldn’t get air. It doesn’t have any power. After fixing it. It’s been removed two more times same issue. And has ate three power steering pumps and hydraboost. It has 68264 miles on it and I got it new. My father in law has a 2020 f-150 it has blew water pump, Evap pump, and a module at 50000. My problem here is they know they have crappy lifters, pushrods, and valve springs for over a decade. The AFM IS JUNK TOO. So why keep putting it in.
My 2021 high country deluxe Tahoe 6.2 failed at 6700 miles and has failed again at 6800 miles. They have had this since ls cam out my 98 silverado had 4.8 did same thing then had that 5.3 did it 4 times, then a 6.0 that did it and took cam and cam bearings with it. The fix is hardened pushrods at least ls7 lifters or better yet morel, and delete the DFM, AFM. I have put cams in many of these with springs lifters and pushrods and have not had the first fail after hammering on them at strip. That tells me that it is well in the realm of fixable
I have a 2021 GMC SLT Crew Cab 4×4. 3250 miles and it went poof. Supposed lifter failure and bent pushrod. I don’t know the extent because of poor communication from service writer. I reached out to GM. I don’t have confidence that there was more damage it was making a racket when it went into limp mode. Every warning light that could come on did. There should be part redesign and a recall issued. I am told by the GMC dealer to remember this because I will be back there again for the same issue multiple times based on his experience with current owners.
2021 GMC Sierra 1500 at4 6.2l with 4700 miles left me 600 miles from home stranded on the highway. Oil changed by dealer at 4200 miles. Verdict : lifter failure. I’m curious as to what is causing this, very strange.
Learned that GM is aware there is a service bulletin for 19-20MY. Lifter drains oil and collapses. Poor engineering. These are specific to engines with the fuels savings cylinder deactivation designed lifters.
Has anyone requested or received an extension of the engine warranty due to this repair?
I have not but I contacted GM corporate through my GM account online and told them about the service bulletin and ask that they honor it. If under 8k miles they will replace both banks of lifters and pushrods. They were only planning on the ones that failed. But I got word today they will do all of them. It’s going to be another two weeks so it will be in over a month. My 6.1L had 3500 miles on it.
Interesting, they only replaced the one lifter in our 2021 Trail Boss 6.2L. 6000 miles on engine.
I’m gonna give you some advise when you get it back check the head bolts, manifold bolts ect. To make sure they have marks on them for tools Make sure they really do both sides. Was told same thing……..
Who’s ready for a class action
2 TRUCKS – 90,000 TOTAL MILES – 1 FAILED ENGINE – 1 FAILED TRANSMISSION.
After my 2017 GMC Sierra dropped its poorly engineered, and now discontinued 8 speed transmission at 74,000 easy hwy miles, my 2021 Silverado 1500 Trail Boss LT now has a catastrophic engine failure with only 16,000 miles.
GM is breaking my heart. I have always been a GM loyalist. Both my grandfathers spent their entire careers working for GM. Nothing else has ever been allowed in the driveway. Seriously. Today, I am sadly rethinking that position.
Let me detail my latest experience (still underway):
– Repeated engine lights kick “service exhaust warning”.
– Take into the dealership who gives it back to me saying they
followed the GM bulletin and could not service the vehicle
because they could not get the issue to duplicate within 50
miles.
– More engine lights. Make another appointment at dealership
– Two days before appointment the lifters on one side of engine
fail. Vehicle is undriveable. Service emergency brake light
comes on. Service traction control comes on. Service ABS
brakes comes on.
– GM reported faulty parts on the engine’s lifters, but will only fix
the side that has already failed. They told me if it had failed with
less miles on it then they would of replaced both sides.
Remember I brought it in once already and they gave it back to
me – “nothing wrong”. Today it only has 16k miles on it.
– So… I call GM. 3 Days to get my case advanced to a case
manager – Shrazondalyn (who is very nice but neutered in her
ability to help me)
– I request a replacement engine or both sides of the engine’s
lifters replaced. 7 more days waiting on a response…. no call.
– Call Shrazondalyn back who informs me my request for a new
engine or full lifter replacement bas been denied.
– My case is still open today waiting on a second “escalation”
request which I’ve already been informed will take 2 to 4 more
business days to get a response, and will likely result in the
same denial of a proper repair, and that I will not be able to speak
with the actual staff member making the decision.
So where does that leave me…
It leaves me with a brand new truck whose other lifters are likely to fail and leave me stranded on the road.
It leaves me with a potentially damaged cam that will fail in another 10 – 15,000 miles and again leave me on the side of the road.
It leaves me in a position where I am forced to sell the truck, or pay myself to fix it properly.
The dealership quoted me $3500 to replace the other side of the engine’s lifters. I am broken.
Last year I forked out $4400 to replace a transmission, and now after patronizing GM and purchasing what I thought would be a reliable 2021 Silverado Trail Boss, I am left with the option of another huge vehicle expense or a forced sale of my truck.
I am terribly disappointed in not only my personal experience, but discouraged by the the response of a company I have chosen to support my entire adult life.
I currently own three GM vehicles, but if they don’t get this one right, I am afraid it will be my last three.
It’s so sad that whatever is left of US manufacturers be it cars or washing machines, they’re failing their loyal clients. I’ve had 6 Tahoes since 1996 and had issues with all- most covered under warranty – nevertheless, problems.
My 2015 dropped a lifter at 95K miles and the repaired that one only under my 100K warranty.
I now have a 2020 Premier and I paid about $2K additional to get the engine and trans warranty extension send to 150K Miles.
Now the dealer is hounding me to service that trans, trans case, engine, etc over and above what’s normal. My position is that I will have them service as normal so the own any breakdowns.
My next SUV will be a Lexus.
Three weeks ago my 2021 Chevy Silverado 1500 LTZ with the 5.3L Ecotec3 VI (L84) suddenly and unexpectedly starting having engine issues. It turns out that the lifters on the cylinder head are having “multiple misfires” on both banks of the cylinder head. My local Chevy service department claims there should be no permanent damage. I hope that is the case.
I was told yesterday that the parts are on back order and that it could take another 2 to 3 weeks before they come in. Once they come in, it will take another 2 to 3 business days to install the new lifters. At best, by the time my Silverado is fixed, it will have been out of commission at least five to six weeks. Yet, Chevy has not offered to provide a loaner even though I depend on my truck for work.
I’m not looking for special treatment, just fair treatment as a customer who spent over $50K on his new Chevy truck. GM Financial hasn’t offered to suspend my finance payment while my truck is inoperable. If anyone in authority from GM or Chevy happens to be reading this, please know this type of issue and lack of service and concern is inexcusable and will do irreparable damage to your reputation and future sales.
I chose Chevy over Ford and Ram. I thought it was the best value for my money. But at this point, I’m questioning my decision and hoping GM will do right by me and anyone else experiencing these issues. Chevy, you still have a chance to win me over long-term, but time is running out.
Thank you.
I would insist on a loaner.
The dealer gave me a almost new Tahoe to drive both times my 2021 went in and I didn’t ask. The dealer has been awesome in supporting me but they are I think someone here also said “neutered” in what they can do.
How do I know if my vehicle is affected?
Thank you for sharing this article. I have a 2021 Tahoe Premier that just went in the shop on Wednesday with a valve tick and multiple Service alarms – ESC, Traction, OIl light, etc. Vehicle has 4300 miles on it. Dealership can’t get parts from Chevy and is trying to get parts from other dealerships in the area. No time line and they do not have a loaner vehicle available for me.
Best wishes. If they only replace 8, you will be back.
I made them get me one….the want to give a nissan versa…I told them no…I need a truck, I drive a truck.
They gave me a Dodge Ram…they have no time… is been a week, they give me the list of parts they order and they are going to replace all the lifters, but it seems like they just replacing 2 pushrods…so waiting…if anybody knows whats going to happen with this problem please post it or can guide me of what to do next because my 2021 sierra elevation went in with just 7300 miles also this happen on the highway at about 72mph and yeah it was scary…..
Curious if anyone has been successful in getting an extended factory GM warranty after experiencing the failed lifter issues??
I posted a few weeks back that our 2021 1500 Trail Boss 6.2L failed with 6000 miles. We have our truck back now. Wife is not happy about the possibility it could fail again, it is her truck and she loves it. But the reliability concern is a big issue now. I would think it would be near impossible to get GM to offer an extended factory warranty…as that could mean they admit something is very wrong in case of litigation down the road.
Well I asked that question and they increased my drive train warranty from 5 year/60000 miles to 5 year/ 100,000 which isn’t much of a big deal because my truck currently is 10 month and has less than 5000 miles so in the long run they really didn’t help me. There is no way I will be even close to 60000 miles in 5 years. I wanted to buy the truck when my lease is up but it may be going back.
Just picked mine up after repair. They warranty the repair for 2 years. So if your near the end of the warranty that is great. My truck has 3500 miles so the warranty extension doesn’t matter. Because if the low miles they replaced all of the lifters and one pushrod and guide. Cam was fine. Runs smooth. I cannot tell you if this is a short or long term fix because I believe that the engineers have not changed the design of the failing lifters. Took 4 weeks due to parts shortages.
2021 AT4 6.2L from Canada, Just got my lifters replaced after 8300 KMS on her ( 8 month old) 1 oil change,
came back from Camp, the next day knocking sound, Multiple faults showing with Engine light flashing
Took her in Monday Morning, had her back next day by 4:20pm
So far so good
They only told me, things happen… WTF
Yep I am holding my breathe every time I drive it. Don’t trust the truck.
Just got my truck back after a month. I was planning on buying my truck after my lease runs out but in hearing this could happen again because of the flawed design this could be a game changer.
Why oh why do people still keep throwing their money away in GM vehicles. Always miles of justification about GM and how machines break. Yes machines wear and brake but Toyota’s hold together beyond 300,000 miles. GM falls apart regularly under 50,000 and in some cases 5,000. GM is selling you the cheapest crap at the highest prices. Quality control is non existent.
Really wanted American to support people jobs and effort here. Figured this engine was well sorted after the years of service. Toyota sheet metal has been a tin can historically. They have really come around in the last couple years thought. Ford V-6 is not up to the job with timing chain issues and Ram is overpriced. Hard to support a foreign company. Sorry to disappoint anyone who is good on that.
I experienced this problem this Labor Day weekend (2021) in northern Montana but I was traveling from Texas! We are furious as they have no idea how long it will take to get parts and repair. NOT first in line at dealership either for this same repair. We will have to fly home and fly back whenever it is ready. Never was notified about problem when I bought the truck in January and it looks like GM knew about it way before that
Don’t know why there isn’t a class action suite going.
This is a simple problem with very complex solutions. It is a stiction problem. GM’s solution was to go to 0W20 oil but the real issue is very tight clearances and the build up of oil byproducts that coat parts and decrease clearances to the point where parts lock up do to stiction. Need something like hot shorts SE to clear the coating off of parts. In the case of AFM lifters it is the buildup on the inside AFM plunger.
I have a 2021 Sierra with a 6.2 that failed at 7,100 miles. Collapsed lifter issue, backfiring and total loss of power left me dead on the side of the road. They removed the heads and found scoring on the cylinder walls. They are installing a new long block.
Very disappointed to have this engine fail so quickly.
My 2021 7 month old Denali 1500 Crew Cab is in the shop for lifters – we are not happy campers – they have no loaner cars to give out and it is very difficult to get a rental car and we are on a waiting list. I have a GM case worker, that is suppose to expedite the parts order & rental vehicle – we will see what happens. Last year, like many small business owners, we took a huge hit, lost 85% of our business, but made it through and are now trying to rebuild our business. We have worked hard to rebuild our business and now this happens. I use this truck for my business and need it for my service that is sometimes 7 days a week. Now I am turning away business, due to transportation issues with my new truck. So one might ask – why buy a Denali – since I am getting ready to retire, we sold off some long term rentals with the market being so good, and I talked my wife into buying the “The Ultimate Driving Machine” . I had a 2014 GMC SLT that I loved despite some oil issues, I probably should have kept that one. I thought I was buying the best truck on the market, after doing a lot of research, and a better truck to pull my boat on a trailer – it is quite clear that GMC is knowingly selling defective viechles to the American public as this evidently is an issue that they are well aware of. It is ridiculous for anyone spending their hard earned dollars to be going thru this. I tried to take my truck to another GMC dealer, that told me they have 3 2021 customer Denali’s waiting for lifter replacements. It is amazing the taxpayers bailed out all of these companies when they cried the blues, and received billions of dollars – GMC should be bailing us out and buying back our defective viechles.
I feel your pain. My 2020 Silverado 6.2 has been sitting on the lot for 3 going on 4 weeks. I finally got a rental after 2 and a half weeks. I love the truck, but this is ridiculous.
Sharkman,
The big businesses have the government in their pockets. Every time a class action or large lawsuit comes up against GM, it gets to congress, not the supreme court and the cases are dismissed. Remember the exploding gas tanks outside the frame rail? GM settled by giving everyone a $1000 voucher towards another GM vehicle. Then the rusting brake lines- Congress ruled its a maintenance issue. Now, the same will happen with this lifter issue.
I’ve had Tahoes since 1996 and now on my 6th (2020). Never had any real issues except the 2009 that seemed to be made on a Sunday night during the Super Bowl. Warranty covered everything that went wrong from header pipe that was bent on installation to differential with low oil. Then my 2004 Z71 developed a lifter knock at about 100K miles and i had the lifters and oil pump replaced. The mechanic said that the 5.3 was notorious fro lifter problem back then. That truck went on to 250K then was tee boned and totaled.
Anyway, i always buy with extended warranty to 100K miles and now my 2020, extended thru the dealer to 150K miles (CNA Insurance) That way, someone else owns the problem. I know we should not have to do that but that’s how i safeguard myself so that i could drive the vehicle OI love. My next love will probably be something Japanese.
This is a sad situation to see American firms screwing their loyal customers who even footed the bill for their bailout. In bankruptcy back in 2008, all of the long time stockholders lost their value and the new stocks were offered to members of congress first. Go figure.
This is a situation where big business owns the government and it’s coming home to roost on the American public now- not foreign countries anymore.
Just waiting on gm to go bankrupt. Once their electric cars fail they’ll be done.
The replacement lifter bank for my 2021 Trail Boss arrived at my GM dealer yesterday, on Friday. However, my repair will be further delayed because they don’t have the head gasket. That’s right… No head gasket! Unbelievable. My new truck is just sitting there after three long weeks.
My 2020 trail boss 5.3 just messed up with the lifters I’m assuming 18k miles and sounds like a singer sowing machine. RIDICULOUS
Don’t assume.
I can’t wait to buy my next Silverado. As soon as I can,I’ll be on the lot getting my 2022 Trail Boss . Maybe I’ll get the ZR2. Not sure. Either way, I haven’t had any problems with my Silverado.
My 2017 Yukon XL is now in the shop for “replacement of the active fuel management lifters, camshaft and lifter guides and push rod and bolts and head gaskets and VLOM” total price $7595 and GM is offerring $1300 in help. Should i take it or find an attorney?
How many miles? First take, I would take because you’re not going to win against GM. They have congress on their side.
Work with the dealer and maybe, figure a trade in for a newer certified pre-owned or new.
On the other hand, you’re getting an almost rebuilt engine so, getting it fixed for about $6K out of pocket is not bad.
You lawyer will want a $5K retainer win or loose.
78,000. Currently not driveable so not sure how I could pull a trade?
What assurances are there that after this fix it won’t happen again?
Dave W.
I had a 2004 with a lifter knock. Had the lifters and oil pump replaced and the engine was new again. Ran another 100K before being Tee Boned and totaled at 250K miles. Got $8,770.00 from Insurance. Albeit, that was not an AFM vehicle.
But, i had a 2011 with lifter collapse at $94K. and was repaired under my 100K warranty. Worked well until i traded in 2020 with 130K miles.
The engine and truck overall are very good except for this AFM system. You are getting a renewed life on yours.
For 8k you need to find another shop. You could put in a crate motor for less.
Mine cost 5k for both banks of lifters. I bought the warranty when I purchased, only cost $100 out of pocket to get done.
how many miles did you have? I’m at 78k so i don;t thinbk i can get a warranty. if i’m wrong send me a link!
Dave, I think you can purchase warranty on the repairs. Further, my dealer got my 150K miles warranty from CNA insurance so there are credible options out there. The service managers know the good ones that honor their policies.
It helped that I bought 6 trucks from the same dealer.
Had 39k when I bought it. Got the warranty then. Lifted fail at 73k. A/C fail at 65k. All covered under warranty which I paid $3500 at time of purchase
Protective is the name of the warranty company
I can, why recall something when you can let poor souls run out of warranty and it do it again then make tons of money off your own ignorance. They are putting same lifters back in I don’t care what they say. Already done mine once it’s raising Cain again less then I don’t know 20 miles after repair. Talked to mechanic at gmc dealer near me he said he had one not even make it out of shop and do it again. If they actually cared they would fire whoever came up with the fuel management throw it in the garbage tell epa to shove it. It’s not like they are not lobbying anyway. And buy lifters that are made better. I’m not buying the came out of this or that factory. How many Delphi lifter factories you think they really are. And why would they make them any different. Same process same parts. It’s called being greedy and getting caught. Do you see any nascar or road race or drag race gm engines having massive lifter failure? Nope that tells me that they can but refuse to fix it
Has there been any new progress on this issue? My 2021 Yukon Denali just had a lifter failure at 5k miles. All 16 have been replaced, but it happened 400 miles from home and now I’m trying to work a resolution with GM – either buy back the vehicle or drive it to me. Can’t believe this problem wasn’t recalled when it is so well documented!
I’m with you Scott. I’ve been wondering the same thing.
I am on my second 2021 GMC Sierra 1500 with a 5.3 motor. I got the first one in January had lifter problems at 3600 and 5200 miles the dealership replaced the lifters but o didn’t want the truck back don’t try to get gmc to work with you they don’t care because I didn’t hear one word from gmc even though Laura Buick said they was working with gmc. I got my second gmc in august now it is at the dealership with the same problem as the first one.Also Laura Buick said I was supposed to be get trade assistant from gmc which was a bunch a bull because it was just like getting a new truck they should have gave me the second one at invoice price but they are too greedy and don’t care about the customer when I get this truck back I am trading it for a Ford or dodge I will tell everybody not to deal with Laura Buick or gmc because of my experience.
Stop buying GMC products its tge only way they will do simething. Hit them in the pocketbook. This problem has been hapoening since atleast 2010 when my escalade engine failed due to lifters with 71,000 miles
They’re also sensitive to social media, like what we are saying now. It’s bad press to have GM know about a bad batch of lifters, issue an internal service bulletin about them, and then just wait for customers to be stranded. New engines shouldn’t have major breaks at 5k miles.
If this has happened to you, you should be posting here.
Mine was fixed at 7.3k miles and it have a vibration on idle now that they insisted that is normal….they are so full of s…my 06 silverado with almost 300k miles does not vibrate like that on idle ….
Yup same here they said it’s normal. I been a mechanic for almost 20 years and my shaking 7k engine ain’t normal. The lifters come apart not collapse where they think all the metal goes? And if a collapsed lifter bends a pushrod well they got way bigger issues. If it bends the pushrod lifter pieces were stuck wedged bouncing around and you driving at several thousand rpm time you realize what happens and get stopped somewhere damage is done lifters ain’t gonna fix that every time. And I’m being generous when I say that. Start pulling oil samples after these “repairs” what’s funny is we get lifters for a Chevy or gmc but I know where an excalade is on the 4th engine from same thing. What’s the word liberals use social inequality haha. Can’t have the Rich folk stranded but the poor working man that’s no biggie.
I have a 2021 Sierra with 6000 miles it’s at the dealership it’s been there a week now lifters and waiting for parts
I have a Sierra with a 6.2. Lifter failure at 6k so they pulled the heads and thought they would slap it back together. I saw scratches in the cylinders from lifter bits flying around in there. I wouldn’t authorize them to proceed and told them that the only thing that I would let them do was put a long block in it, and they agreed to it.
I have the clicking noise coming from the motor. Exhaust is fine , it’s definitely internal . Will it throw the Check Engine light ?
2021 Trail BOSS New in July 1,845 miles in Shop LIFTER PROBLEMS VERY DISAPPOINTED..
Should of bought a Toyota or a 2000s GM truck.
Your consumer stupidity costs you.
2021 Yukon AT4 been in the shop for 3 weeks now. Figured I’d throw my hat in here to let people know.
My 2021 Trail Boss with 9K miles was recently in my Maine Chevy dealer’s shop for 3 weeks to replace the driver side lifter assembly. GM refused to replace both sides. Seems to run OK for now, but I’ll be driving 3 1/2 hours each way down east and back tomorrow. It’ll be like waiting for the other shoe to drop, and there are no GM dealers within that range.
No problem with my Trail Boss . Can’t wait to buy a 2022 when the come out . It’s funny though, I have never heard anything about this issue on any other site I am on regarding GM products .
How many vehicles are affected by this so far? Anyone?
Was on our first trip with only 800 miles on the 2021 AT4, check engine light went on and the truck turned off. Wouldn’t start again. Said Emissions system error. Had to get towed to the closest dealership. Our truck was fully packed with gear for a 10 day trip. The dealership basically said tough luck. They had 7 other trucks there for the same reason. Most have an issue around 2,500 miles but for some reason ours was sooner. It will take several weeks to fix. No loaners available and had to get a family member to drive from 2 hours away to pick us up, unload our truck and reload it all in theirs. Horrible experience. Our truck has been in the shop more than our home and now the trip that we planned for is sidelined. We had booked a hotel for the night but cannot make it there now that it delayed us 7 hours to get towed, figure out the problem and then get a ride. Really bad start to what could have been an awesome trip. GMC doesn’t seem like the way to go.
Same story for me, and the worst part of it seems that GM knows and doesn’t care.
– When mine broke down I called OnStar. Completely useless. They basically only Googled dealers and gave me phone numbers. Thanks, big help
– Called a dealer and it was off hours (Sat, 3:00PM) so they said they weren’t authorized to even look at it. I limped there anyway (what choice did I have?). Sales people immediately recognized the lifter problem and graciously gave me a 2020 Yukon, which I used to get to my destination, but said that was only temporary and I needed to exchange for a service loaner.
– I then contacted GM support and established a POC.
– On my return home from our trip, I swung by the dealer to exchange the temp car for the service loaner – an economy car that clearly couldn’t carry my family and supplies. Service Manager apologized and said they’ve seen the lifter issue a lot and GM should have recalled the car. They needed to special order lifters since all 16 had to be replace and had no idea how long that would take. They didn’t have any other options than the economy loaner and I should call GM support myself for more help – they haven’t had luck with them.
– I immediately called and texted my GM support person – CALL ME NOW! No response and I was only able to leave a voice mail. I found a way home with the service loaner (400 miles) along with alternate transportation for my daughter.
– Multiple days later GM contacts me and someone new has taken over my account. I complain and ask about them buying the car back. That request takes 5 days to process (today is day 5).
– The next day the dealer calls and says the lifters have been replaced – when can I pick it up. I can’t, it’s 7 hours from here. They want their loaner back.
– I contact GM support again to figure out how to do the exchange. They say they can’t do it, I need to call GM roadside assistance and arrange for a “reunite.” I call and roadside says they don’t do that either, but would e-mail the people who do and I should expect a call. I asked to be cc’ed on the e-mail. Can’t do that either. It’s now 4 days later, no call. I guess if the service guys want their loaner back, they’ll figure this one out.
No one at GM that I talk to ever seems surprised by the story and just passes me on to the next person. A very disappointing experience that has convinced me that even if I get the car back, it can’t be trusted.
Your right they should be recalled as they haven’t fixed the design flaw just replaced with the same products so we can anticipate this happening again.
I loved my 2016 Tahoe and made sure I only took it to the dealer to service it. And then, at 60k, the trans completely broke into pieces. It was under the extended warranty, and they replaced it with a new one, but it was never the same. Currently, it is in their shop again because of failed lifters/damaged cams, and I’m sure there are other problems. Mind you they just serviced it two days ago.
I can’t wait to get it back and trade it in!🙅🏽♂️
Let me know where I should go? Leaning either ford or BMW🤷🏽♂️
BMW would be even more stupid.
If you want reliability and less agony for your wallet get either a Toyota or Honda.
Or find an early 2000s GM Truck/SUV with low mileage.
Is this a new problem with the AFM lifters or a continuation of the AFM lifter fiasco that started with 2007 model year engines? If so, install and afm delete cam and standard lifters. OR, install the AFM odb2 plug that disables AFM.
Nothing like spending 50,000 on a new truck and dropping lifters at 5 000 miles should have bought a ford
GM should be required by law to replace every truck purchased with a brand new truck including a 250k mile warranty.
There is zero way they produced this many failed lifters without knowledge of the defect.
Clearly intentional on the part of the manufacturer. GM has been building engines with hydraulic roller lifters since 1986. This is unacceptable.
Is there a way that we can act as a group? What has been equally disappointing has been the blowoff I’ve gotten from corporate GM. Mine left me stranded 400 miles from home and GM was of no help. Unacceptable for a vehicle with 5k miles. My wife had to take time off from work to go back and get the Yukon and it is now definitely idling more roughly giving me no long term confidence. I intend to trade it in for a 2022 Expedition as soon as I can.
I have a 2021 1500 with 13000 miles . Had this issue and left me in the middle of a six lane highway. Then gm said they won’t give me a loaner because they have none. They said they will have my truck for over 3 weeks. And they won’t give me something to drive. It’s bs
They have screwed a bunch of us. Time for a class action lawsuit!!
I have a 2019 RST 4wD . I put miles on trucks . I’m at 80 k and at cold start my truck sounds like a handful of pebbles in a metal bucket. The same dealer I’ve bought the last 7 new chevy trucks is putting me off although I’ve informed them .it’s probably because I bought the 100 k powertrain warranty and mine explicitly says for ANY COVERED REPAIRS IM GUARANTEED A LOANER. THEIR LACK OF CAPACITY IS GOING TO COST THEM MORE WHEN IT SEIZES OR BENDS A ROD. I DONT WANT THAT DOWNTIME BUT THEY SEEM CONTENT TO BE THEIR OWN WORSE ENEMY AT TIMES. ANY ADVICE ON DEALING W THEM. I FELT LIKE I HAD A GOOD RELATIONSHIP W THE SERVICE MANAGER OVER 12 YEARS AND A HANDFUL OF VEHICLES. I FEEL LIKE THEY DONT VALUE MY BUSINESS AFTER A HALF MILLION IN SALES AND SERVICE.
Same here no rental no love!
I kinda like my Chevy dealer in Medford LI. But there service managers gotta go before I’d buy another truck from them. My trailboss had lifter issues around 8k I’d no parts available for 3 weeks , to be fair she did get me a loaner CAR. CHEVY 112 just needs to replace there service service manager and I believe there service team is a o k!
I think keenas1962 is right. Time for a class action lawsuit!! My 2021 Silverado with 7600 miles on it has now Been at the dealer waiting for parts for three weeks. They said there replacing lifters on both sides and have 3/4 of the lifters, wait for the other 8 which is ridiculous! Why wouldn’t GM ship them all at once??? It’s all BS. GM knew they had this issue for three years and have done nothing about it
2021 High Country Tahoe been in shop for almost two months now. Dealer installed new lifters, after a long wait for parts, and realized after starting that lifters were for the smaller engine. GM replacing the engine now. GM paying for rental car.
Just took my 2021 Trail Boss to the shop due to bad lifters. It has 19,000 miles so they’ll only replace the one side. They were nice enough to give me a rental but it’s a Chevy Spark. Oh well, better than walking I guess. Should have went with a Toyota!
My 2021 X31 GMC Sierra is back in shop after being in the shop for lifter replacement at 9200 miles .This time it is for service 4 wheel drive system,battery saver active,voltage gauge is fluctuating al of this after only driving 700 miles.GMC doesn’t care about Qaulity or customer satisfaction if they did they would have a recall with all the lifter problems these trucks are having .The government should be notified about this did they not bail out General Motors .Also this is my second 2021 Sierra my first one the lifters failed at 3600 miles and 5200 miles gmc did not help out when I bought the second one.Just goes to show is all they care about is getting the customers money.Time to buy a Ford or dodge .
I had a lifter issue with my 2020 Silverado 6.2. What a nightmare. I won’t bore you with all the details. After going round and round with GM about what they wouldn’t replace…..Almost 2 months in one of the techs figured out that engine replacement was needed. I hate to say it but replacing makes me nervous after all the comments I’ve read.
GM has put customers and dealerships in a terrible place.
It seems here that the apart from the lack of confidence with the vehicles, that the biggest complaint is the poor service at the dealers. I have to say that in NJ, I’ve had a few dealers that I deal with although I bought all 6 Tahoes from one dealer. I pick who’s schedule fits my convenience for service. All major work / warranty work usually gets handled by the dealer I bought from. I have had issues with some of my trucks but they were always covered by warranty and / or recall. My 2016 LTZ dropped a lifter at 94K miles and the dealer replaced the one bank. It worked fine until I traded it in at 126K for a 2020. My 2020 now has 36K and running fine.
My dealer and service department always make a loaner available or they pick up the rental of an Enterprise car for me.
a box of donuts, holiday gifts and little trinkets go a long way with the service department like all other service providers I use.
I know that we should expect better quality for a $70K+ vehicle today but even my washing machine and refrigerator needs service and repairs from time to time. I would suggest that you buy the extended warranty for the drive train. All dealers offer warranties up to 150K miles from CNA Insurance, etc. for an extra $1700.00
Had a 2015 Silverado LTZ Z71 with the 6.2 and 8 speed trans… my dream truck that was always properly maintained. First failed torque converter at 40k kms- got one thing done for free under warranty. Then a AFM lifter failed at 86k kms, fixed it and bought a Range Device to disable AFM- then when deciding if going to keep the truck after that the trans started shuddering again and a lifter failed again within 1000kms of previous repair. GM was completely back ordered on lifters… so there is all the proof you need that it is a BIG PROBLEM with the +2014 trucks particularly and seemingly worse with the 6.2 engines. So I did a trans flush myself and fixed the lifter in the driveway for $400 and sold it back to a dealership. Fuuuuuck GM! After being a lifetime owner and supporter they will never get a new(er) vehicle sale from anyone in my family now. Ridiculous what they are charging for this destined to fail junk and using EPA as their scapegoat. A friend has 2019 Chev 6.2 truck that has almost spent more time in the shop than he has driven it, no lemon laws here but many things have failed on his near new low mileage truck including lifters. In case anyone is wondering, its all a ploy to get your (repair) money. The gasoline quality is complete garbage these days and adding ethanol to it is just a ploy to turn older useful reliable machines into expensive junk. The $ goes into corporate pockets and offshore, and they laugh at your misfortune. I’m now driving a lovely rust bucket 4.8 truck with 314k on it that is much more reliable than the new junk
How many of you gat your truck back and now it feels like you are driving an old washer machine?, I got mine fixed about 3 months ago and since the lifter repair it feels like a washer machine, took it back only to get them to say it is normal the truck is good there is no code. I have been back 3 times because of this vibration only to get the same response…now Im just waiting to the engine to blow so the can get the codes they want to see.This is crazy..m
I am already working with an attorney, my situation more than qualifies as a lemon. NO WAY AM I JUST WALKING AWAY. GM needs to pay !
Yep. I’m just waiting for lemon law to play out. I’ve already been to the dealer 4 times. I’m done with this POS
Another one for you. Lifter went out on my family road trip. Mileage was 5800. Since it was on a Sunday stealership would not give me a loaner because service dept was closed they said. Had to pay for rental car to finish the road trip. Very upset with this. Truck was fixed but it doesn’t feel right anymore to me.
GM should just give up on cylinder deactivation technology and only use VVT and add port injection along with the direct injection. The 3/4 and 1 tons and the vans don’t even have this problem. If your truck is out of warranty, spend the money and delete the system ASAP. There’s aftermarket companies like Texas Speed and Performance that offers AFM/DFM delete kits to solve the problem. For 4.3 V6 Silverado/Sierra owners, a GM van cam and lifter swap is offered by GM themselves.
The new 6.6 gas burner in the 2500 doesn’t have fuel management gets bout 12 mpg. Old tappy get bout 19 mpg and that’s local with engine crapping out fuel management works if you can get it too work. But it’s not worth the trouble may be time to walk away from pushrod engine. Or wait, you could put good parts in it, dang why didn’t think of that
Just got rid of my 2018 Silverado with the 5.3.
Had lifter issues at 25000 miles. It had 34920 miles when I traded it. Started having transmission issues. I didn’t trust it any longer.
Everyone I know that have bought chevy’s years 2019 through 2021 has had there trucks in the shop with lifter issues around 9000 miles. So when the power train warranty runs out who pays for the repairs. Bet it’s not GM.
Needless to say, I am now the proud owner of a Hemi.
Well, my right bank lifters went on my 21 Silverado, 6.2 at 7900 miles. After some persistence and help from my dealer I got a CCL, component coverage letter. It’s a 6 year warranty,100,000 miles from date of repair. Transferable as well. While I would have rather not have to pursue it I guess it’s somewhat of a victory. It’s still ridiculous that a vehicle with a msrp of all but $61k should ever have this type of failure. The irony of this is the same day my dealer went to GM, GM called me and told me I wasn’t eligible because I didn’t have enough miles on my truck. What an asinine excuse. Anyway three days later my dealer calls and tells me I was approved. Just got the letter in todays mail.
GM did approve the lifters to be replaced on both sides of my 21 Silverado. I waited to call GM about the CCL letter till after I got my truck back. Obviously the dealer went to bat for me which they should have, myself and my family have been buying GM vehicles from them for over 45 years.
4400 miles on my z92 Silverado
Driving it today and had misfires that lead to a bent pushrod and collapsed lifter. Should have never traded my ram in for this garbage who knows how long this repair will take and what headaches to follow, heads gotta come off and all. Total incompetence from a once trusted American auto manufacturer.
My father and I both have 2014’s with the 6.2 and both had catastrophic valve train failure at 106K miles just off warranty. GM didn’t cover a penny for the $6000 in repairs. Seems like GM should have a recall for this issue. These ecotech engines are garbage.
They know they valve train is crap hardened pushrods and morel lifters problem solved they can do better they choose not too and government will let them do what they want
Warranty isn’t any good if it is gonna be on side of road or without vehicle to drive my Tahoe 2021 has been three times for lifters just got it back and already ticking again at 13500 miles they gonna piece meal it till. It gets out of warranty then it’s your problem. I been patient with GM DEALER has gave my wife a Tahoe to drive every time and has been solid but they can only do what GM Tells them too with warranty I do Cummins warranty myself. However with Cummins it is always at the discretion of the mechanic. If I had seen the same car three times for same issue it would have got an engine at this point but what do I know I’m just a glorified part swapper
I got a 2016 GMC Yukon Denali beginning of October. Went in the shop for a stuck thermostat, less than a week later, in the shop again for a bent rod. Its been in there for 7 weeks now waiting for a part that is on back order. I know nothing about parts but the guy called it a “v loom” anyone I talk to has no clue what that is. The guy at the shop said the vendor still has no ETA for delivery. So I have no clue when I will get my Yukon back. I have a 3 year warranty on it. So I am stuck with a car payment on a vehicle I can’t even drive. I am soo pissed!!
This is very disconcerting. We bought a 2017 Yukon XL in May of 2021 with 48k miles. I took it in a few days before Christmas and it needs the lifters and VLOM replaced. It’s been sitting there waiting on parts. For the money and size for my family, with HD towing for camper, I couldnt find a better truck (on paper). No end in site as to when it will be repaired as they can’t update when the part will be manufactured and received.
I had the lifter issue with my 2021 Tahoe at 4700 miles back in September. Took 6 weeks for the repair. I just received word from the Dealership that GM approved a warranty extension for the full powertrain and electronics to 100,000 miles. CCL letter should be in hand this week. I made sure the extended warranty is be transferrable in the event I sell the vehicle before 100,000 miles. It was not a huge issue to get the extended warranty – a couple of emails and a phone call with the service manager at the dealership.
Good luck to all!
I just got my 2021 GMC Denali 5.3l out of shop today, 1-22-22. My check engine came on first at 3,500 miles code multiple misfire. Took to Dealership after 3 rd cel. Nothing found. Told it happens a lot. So after no noise or not feeling or hearing a misfire I didn’t waste my time taking to Dealer and them do nothing. CEL four more times , same code P0300- multiple misfire. Reset code. But on 1-8-22 it started vibrating and popping indicating misfire and multiple messages came up, service electric parting brake, Service ESC, steering assist reduced, lane keep assist system not available, etc. The computer was obviously overwhelmed. Took to local GMC dealer and told it was lifter failure. Parts back ordered and told by service tech that would only fix one side per GM with only 8039 miles and an oil change at 2000 miles. I was persistent with owner that fixing one side set me up for failure and another repair down the road. Even if repaired under warranty I would be without my truck and would not trust going on a long trip for fear of failure will out of town . The owner understood my point and talked with service manager and they did the right thing and replaced both sides. I was fortunate but reading all he horror stories in comments really angers me that GM is not recalled all the vehicles with faulty parts. They will eventually be sued enough to trigger a recall but at the expense or losing many long time faithful customers because of poor and possibly criminal customer service by knowingly selling vehicles with faulty parts. I was one of the lucky ons I guess as I was without my truck for only 12 days but no loaner. I have a spare vehicle so no big problem but lots of owners don’t gave that option.
A class action lawsuit has finally been filed (December) on this lifter issue. Not sure it has been mentioned yet on this site.
My 2020 1500 is currently at the dealership waiting on back ordered parts due to the lifters…for the second time! One side was replaced already…fast forward 8 months and took it back in for the same thing. I was told that there was an update to fix the problem. I picked it up and had it back the next day because it was doing the same thing. Now they are replacing both sides…ffs
What’s the update on fixing the problem??? Just replace until they go out again or actually fixing something that prevents the lifters going bad or push rods bending?

Haven’t even had my Denali 1500 for a year and the left side lifters are done .
I have a 2021 GMC sierra with the 5.3L that has 26,427 KM’S and im starting to get a ticking noise on cold start ups and when reving the engine.
Lifters going out, just like mine did
2017 GMC 30k miles. Lifters,push rod and a valve. Truck tied up for weeks . This problem has been going on for years. How can they not do something sensible with this? Just keep replacing them instead of fixing the problem. Just the same thing until the warranty runs out. Then scrap the truck. LOL What a joke. Have been a lifetime GM man.
6.2L 2021 AT4 just failed while hauling a trailer – major misfiring, lack of power and lifter noise. The outcome was a bent lifter and downtime for the repair. The truck has never run so well since.
My 2021 GMC 1500 AT4 with 5.3L engine, 16,000 miles broken lifter and bend pushrod. This shouldn’t happen.
I left a lengthy comment on 1-22-22 on my lifter repair on my 2021 GMC Denali 5.3L. I ask my local dealerships Service Manager to get me a ComponentCoverage Letter (CCL) after reading in this GM Authority forum where others had gotten CCL for engine extended warranty after having engine repairs. I received my CCL today from GMC giving me 6 years and 108322 miles coverage on all engine repair. I had 4 years and 51,678 left remaining on factory drive train warranty. I am very pleased with GMC stepping up to keep a valued customer. Be persuasive and beg if you have to to get this CCL if your lifters fail( or any other engine repair). Good luck and your welcome.👍
Im glad you got some additional warranty – but asking people to “Beg” to get something that GM is ignoring and is clearly a problematic defect sounds somewhat ridiculous to me. IF YOU THINK YOU ARE VALUED THEN YOU WOULD NOT HAVE TO BE PERSISTENT NOR BEG. GM is patching this problem REACTIVELY and one customer at a time and ignoring the bigger issue. The extended warranty of getting you to 108K miles maybe good enough for some but for a large number of people who expect their vehicles to last upwards of 200K miles or more is not a comforting policy – yes its better than nothing but its simply kicking the can down the road. Most ordinary people who spend $50-$80K for a truck or SUV expect GM to be more proactive. Best of luck to you.
They should be fixing all the apes that’s had this lifter problem I had it on the left side set me back almost $6000 minds a 2009 GMC with a 5.3 V8 and that was with a extended warranty GM should be replacing all the lifters and everything from when it started till now
My lifter failed at 16.000 miles on my 2021 5.3 engine. They replaced half (8). Waiting for my second failure.
2021 Silverado manufactured in September 2021
15,000 miles setting in shop with cracked head and busted lifters. GM should be recalling these trucks.
16,000 miles 5.3L GMC Sierra AT4 collapsed lifter bent rod. Replaced bent rod and 8 out of 16 lifters. Refused to replace all lifters or offer extended warranty. GMC advised on second failure repairs will be covered if under warranty. GMC said they would possibly work with me if out of warranty but of coarse they said the possibility of standing behind there product after warranty is only speculation.
We have a 2022 Siverado with only 4400 miles with this exact problem of the failed #7 cylinder misfire with check a Po300 misfire check engine light code, and what sounds like a valve hitting the piston. It is one of our latest fleet vehicles.
Sorry to hear this. I was hoping that GM had very quietly fixed the issue and we would not see this with 2022 engines – but I guess they prefer to burry their head in the sand and hope people are satisfied with getting a lifter or two or at best one bank fixed at a time.
That’s right KSM. The Dec 2021 service bulletin was for build dates of Sept 2020 – March 2021 so I thought my August 2021 5.3 was safe. I didn’t want to wait longer because the 8 sp with 5.3 was being replaced with 10 for 2022 and I didn’t want 10.
Thanks for your comment Petey. I’ve been reading looking for info that relates to my August 2021 build date in Silverado 5.3. I understood the service bulletin they released in Dec 2021 was relating to trucks with build dates of Sept 2020 to March 2021. I hoped being built 5 months later was the safe range, I guess not.
Wow, sounds like I am not alone. 2021 Silverado Trailboss with a 5.2 and 20,000 miles. Last week multiple codes went off and the engine was misfiring. Diagnosed yesterday with a broken lifter. Like everyone else, GM will only replace one bank and of course the parts are backordered. In the meantime I get to drive a loaner equinox while my $60,000 truck sits in the shop with an unknown repair date. When I pressed that they replace the other bank, the service manager said it would take 3-4 additional hours that GM will not authorize. It makes zero sense! If you have a bad lot of raw material for the lifters it is logical to assume the other side could also be effected. Why wait? Why not just address the problem and move on. I love my truck and am very disappointed in how GM is handling this issue. I reached out to GM customer service to request an additional warranty. That should be an automatic for these types of major engine issues.
GM is a clown show. I went through the same thing, my 2021 Tahoe had been in twice for lifter repair, GM couldn’t document what style lifters had been put in for previous repairs. My third failure on my last visit at 21,000 miles I only accepted repairs with both sides of engine installing new lifters, extended warranty adding 100,000 mile to the 21,000 miles on the truck so a total coverage up to 121,000 miles, and a detailed cleaning before I take possession of truck. They did those things I asked for and I imagine they will do yours too if you throw enough of a fit with them. I still don’t trust this vehicle and expect more problems, but at least it will be warranted. What a horrible experience and a bad taste in my mouth, long time GM owner but no more after I get rid of this piece of crap.
My 2021 just went in for lifters and they were telling me they would only change 1 bank. The new motors have tighter clearences and are balanced motors. That’s how they get such high horsepower out of the new motors. When you replace 1 bank and not the other it isn’t a matter of if, but when the other bank is going to fail if not grenade the motor.
I, too, have joined the “lifter club” with my 5.3 2021 Chevy Suburban after 9,000 miles. Clanking sound during acceleration and a “machine gun sound” after first starting it up in the morning. All is well after lifters and a bent push rod were replaced.
MY 2013 Silverado with the 5.3 started sounding like a thrashing machine at 75k. Dealership fixed under warranty yet when it hit 120k the entire engine seized up with zero oil through the journals. Cost me $8,000 for a new engine. I will never by another GM vehicle. I thought the engine issues were with Dodge Ram 5.7 HEMIs and their roller bearings, but it seems to be more GMs biting the dust lately now that quality is down. And to the lady who said it was racist to call Mexico a 3rd world country where parts and engines are made. It is or that is what I’ve heard for 65 years. Get over everything in your precious whinney little world as being racist. It’s not. You are the true racist for calling all white racist.

I just experienced this issue on my 2020 GMC 6.2 L. The 8th cylinder lifter failed. They replaced the push rod on #8 cylinder and all 8 lifters. I’ve bought GM trucks and Suburban for years and never had this type of issue. Now I’m concerned that this issue may impact the engine life.
Almost all the comments I have seen regarding the lifter/pushrod/spring issue seems to come from understandably disappointed owners with 2021 model year trucks and SUV’s equipped with the 5.3L & 6.2L engines. I have not seen any comments (could have missed them) from owners of 2022 truck & SUV’s with these engines made in 2022? Is this a case of GM quietly fixing the problem but not making a issue of it to prevent a bigger demand for recall or is the problem continuing with 2022 models and will continue with 2023? Im just wondering to risk buying a 2023 6.2L or try the Diesel 3.0L in a
