How GM Dealers Handle Engine Valve Lifter Issues

A few days ago, we published a report highlighting the valve lifter issues some General Motors customers were experiencing in certain vehicles equipped with either its 5.3L V8 L84 gasoline engine or 6.2L V8 L87 gasoline engine. In light of this article, we’ve decided to provide some insight into how GM typically handles valve lifter issues on vehicles still covered under warranty.

If a customer brings their vehicle to a GM dealership and reports a valve lifter problem, the dealership will first determine whether or not the customer has experienced a previous valve lifter issue with this particular vehicle. If they have not and the vehicle has less than 8,000 miles on the odometer, the dealer will replace the lifters on both cylinder banks. If the vehicle has more than 8,000 miles, only one bank of lifters will be replaced.

5.3L L84 V8 engine

If the customer has experienced prior valve lifter failures, dealers can choose one of three options: replace one bank of lifters and offer the customer a 60-month, 100,000-mile Powertrain Component Coverage Letter, replace the entire engine, or reach out to the District Manager of Aftersales for further guidance. The solutions are similar for a customer that has experienced valve lifter issues in the past and had one bank of lifters replaced. In this case, the dealer can replace one bank of lifters and offer a 60-month, 100,000-mile Powertrain Component Coverage Letter or reach out to the District Manager of Aftersales.

The aforementioned valve lifter problem affects 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. More information on the issue is available in our dedicated report.

GM Authority intends to follow the valve lifter story closely and report on further updates as we receive them.

  1. How long has GM been making valves? Because this should be perfected by now.

    They’ve ruined their engines with cylinder deactivation and other gimmicks that the customers don’t want. And now this.

    1. The problem seems to be with the lifters, not valves. Likely it’s just a manufacturing problem or material problem that slipped through QC, this happens sometimes, and GM has to first identify the scope of the problem to come up with a proper solution. Agree though, most customers do not like cylinder deactivation, and it is never completely seamless.

      1. This is more then a GM issue. These are sub standard supplier parts that are near impossible to single out until problems arise. We pretty much know where their coming from, but no one wants to say it. CHINA.

          1. You wish… not Mexico…not for many years. If anything is still coming out of Mexico be very glad. GM had perfected Mexico quality over many years of industry there… now they need to start it all over again in China.

        3. They’re not coming from China. They get about 43% parts from Mexico. If they were coming from China it would be clearly stated on the window sticker.

              1. Take it to the dealership and make sure they are able to identify the lifter issue. Once they confirm it’s a lifter issue call corporate asking for customer assistance. I just ran into this same issue and GM is paying 100% of the repairs.

                1. What is the number of corporate? My sons truck just stopped with only a quick noice in the engine and everything went dead. Its been at a chevy garage for weeks now and he is waiting for them to take the engine apart to identify it is a lifter problem. It would be nice if they replaced all the lifters. The garage at chevy says it needs a new engine. Thank God for insurance but GM should pay for it.

                2. I just spent 7,300.00.On repairs to a 2016 chevy Silverado bought through the dealership in Jan.2017,she had 73 thousand miles on it and I only had 108,thousand miles when this happened. My 35 hundred dollar warranty had expired,and remaining factory warranty did not cover parts down in the engine.I am sick,and have reached out to GM ,which opened a case number up,but still no news.I was so proud of being able to purchase this newer yruck,have had 1990,drove over 250 thousand before any problems, I saved and slaved,only owed 45 hundred and now this….I am screwed ,had to replace all lifters,and had to get it running because, either way it had to be fixed,for any trade in.value,I saved and saved that hard earned money all just to hand back to a dealership that more than likely new this motor had problems, I even gave them a 5 star review years back,I kept all service through them,and I am literally in shock.I know I probably should have purchased another warrenty,but so expensive again and didnt help me the first time anyway,it would not cover a windshield wiper pump motor.My truck was bnb ought in Brandenburg, Ky.I feel I have been raped.

                  1. Holly I just paid out $9000.00 on a GMC Yukon, 2019, 73,000 miles. The first dealership charged me $498 and changed the serpentine belt and this didn’t fix the problem. The second dealership charged me $8475.91. My husband has a Sierra truck 2021 so now we know it will also happen to the truck. We are 73 yrs old and bought both vehicles thinking it would be the last we would have to buy because of our age. We have taken pristine care of them and now this. We bought GMC because we thought they were good vehicles and would last. I should have stuck with my Fords or Mercury’s which caused me few problems in the past.

          1. As I stated previously, GM still makes their lifters in America in Wyoming MI at their GMCH plant on 2100 Burlingame Ave. This factory has been making all of GM’s lifters I believe since the 1940’s. And they supply all of Toyota’s lifters to them as well. This factory use to be known as a very high quality solid/hydraulic/roller lifter producing factory. At one time it was producing millions of defective free lifters when I worked their in the 1970’s-80’s-90’s. But their has been a complete new workforce hired into their now as retirements and transfers to other GM plants happened. I have not been their since 1999 but apparently the new workforce is not getting the quality job done. It does surprise me as when I was working their, there was a whole bunch of check and balances in place to catch 99.9% of any defects. As an retiree and ex employee of this specific plant I too wonder what in the world happened in the name of quality at this valve lifter plant. I have to wonder what changed for quality control since I last worked their in 1999. Is it machining quality? Was their an engineering change to the lifters or a processing change? With so many GM owners having problems with their lifters it makes this retiree wonder what in the world happen to the quality of these lifters.

            2. Problem is GM BS Cylinder turn off in order to make US mileage requirements. Whole engine gets gunked up. Disable that crap as soon as your warranty is up if you dare to purchase GM. It can be done with a tune or disconnect brake booster in some models.

          2. Not sure where you got that from I worked for Toyota. The cars are assembled here. Most of the parts are from over seas. When a part fails they blame it in American manufacturing even though they design and quality control those parts.

          3. My 2020 GMC with only 60k miles is in the shop now for this lifter crap. I had issues with My 2018 Silverado Also. The part that really burns me up is how GM Only wants to band-aid this thing until my warranty runs out, Then it’s on me. They know it’s an issue and has been for a while. That’s why they’re being sued. So FIX IT GM the right way. Either replace all the crappy lifters & DeActivate the DFM System. Or replace my Motor. Otherwise it’s a timebomb waiting to go off again and leave me & my family stranded. You can SELL All kinds of Vehicles and stand on your soap box and pump your chest. But when these kind of Major issues happen , You really find out what kind of company you’re dealing with when they Won’t stand behind what they Sell. Good Job 👏

        1. I installed the Range Technology AFM disabler. I bought a V8, not a sometimes V8. Hopefully that will prevent lifter failure on my 16 LTZ.

          2. I have had a range unit since 2010 and it makes all the difference in the world. No more poor idling,misfire and acceleration issues. If GM wants to use a sometime engine provide the customer with a optional switch.
            This can be done on the DIC control selection and they are smart the service down loads will tell how useful this feature is used,

          3. I have a range on my 2021 Trail Boss. Been on it since 200 miles. At 11,380 miles it had a lifter fail and bent a pushrod. Disabling the AFM/DFM does NOT make the parts any less likely to fail.

I just hit 70,000 and have lifter failure and about to drop $8,000 getting it repaired with new cam, lifters, and delete parts from Texas Speed and Performance. Before I can do this I also had to drop $500 just to have HP Tuners unlock my trucks computer before I can spend another $500 to get it tuned with the new parts. GM said my truck was not on the list with defective parts.

                1. I feel the pain. 2017 Z71. Lifter failure at 32k, dealer told me it was injectors, fixed. Then at 71k miles, the infamous click and check engine light again. Dealer told me it was a scratched cam, wanted $165 for a diagnoses BY EAR and $6k for a new cam. I told them to F-off. Went home and tore top end down – #6intake rod bent, stock cam is fine. I put in a TSP stage 1 (and a whole lot more)
                  I never looked back.

                2. I have a 2021 1500 AT4 6.2. – I just got a call from the dealer, number 3 lifter has failed, they will replace that bank. I asked them why not do both banks but GM only lets them do one. Crazy … it’s obviously going to fail again and GM is just hoping enough last to get out of warranty. So dishonest.

                  1. Yes it is crazy, mine is a 5.3 and they did same thing, argued about it but it didn’t matter. Its a 2021 and my lease is running out so I’m wrestling with buying it or get something else, don’t really trust GM anymore. At least give us a 100k drivetrain warranty.

            1. You can remove the range disabler and gm will never know it was there. It doesn’t rewrite anything, it just doesn’t allow the DFM to activate. But as stated earlier, this will not stop the lifter failure. I have a Range on my truck, just hope it helps. Would be interesting to the the ratio of failures with and without the Range disabler.

              Reply
            2. Would’ve thought by now the wonderful engineers at GM would’ve had this fixed by now since I have a 2011 that has had nothing but issues with the lifters. After reading this I don’t think I will ever buy another GM product again. #Crap!

          5. Have the Range Technology AFM disabler. 2015 GMC Sierra 5.3 l change oil every 4500 miles since new. Had the disabler for about 2 years Lifter 6 went out anyway. All the Range Technology company said is the lifters are bad. So what is the whole point of the disabler. Vehicle had about 72000 miles on it. Lifter went out with the disabler. Not happy.

            1. The Range disabler just blocks the DFM from engaging. it works great but it does not eliminate the faulty lifters.

      5. I like cylinder deactivation and am getting great milage for a full sized pickup and it has been mostly reliable to 55000 miles. We have had one lifter replaced due to what they called sticking. Engine had a mild miss but no other issues and we caught it very quickly. I was not aware that they were to replace the full bank of lifters but they may have done that. The electric engine is a great way to get better fuel mileage.

      6. Has this issue been resolved on 2023 models?

      7. I have a 6.2 with cylinder activation and generally love it! 20 to 24 mpg is common with this on a full-size Chev pick-up with the active lifters. However, ours made it to 94000 miles after all warranties had expired and $7000 later with new cams and lifters, we now have a good pickup. I worry about the lifter issue anytime I see a used GM pickup with active lifters and in how many miles will it go before the lifters fail? We had one lifter fail at around 70000 miles and the extended warranty fixed that one and we were not offered anything in the way of extended warranties or even knowledge that such an option existed Ours was a 2018 Chev Silverado High Country.. Awesome truck except for this lifter issue but I will be very reluctant to purchase another one..

        1. I do have a GMC at4 2021, mine was a lease and was rebuilt (well, half of it) at 15000 miles). My lease ended so I decided to buy it after the dealer sold me a 100k drive train warranty which included a additional 12k bumper to bumper warranty. It was only around 500 do I took the chance. I didn’t even know GM had this warranty available, which I decided to take a chance. This is a 5.3

    2. Valves, bearings, pistons, rings, gaskets, are made by vendors for gm and everybody else. The vendor had a bad run on valves. gm’s quality control receiving unit which takes samples of vendor sourced parts to check for specs and quality did not catch the bad batch of valves.

      This is a relatively uncommon occurrence with manufacturers but does occasionally occur.

      It’s amazing how many parts on vehicles and equipment are vendor sourced these days. Caterpillar in fact sources their smaller diesel engines in their entirety from Kubota and wholly owned Perkins. They
      paint these engines yellow and put a Cat decal on them.

      Caterpillar had a run of bad engine crankshaft bearings from Clevite about 40 years ago. Cat’s quality control receiving did not catch and it was a warranty nightmare. Also created extreme replacement part shortage.

    3. GM doesn’t make any parts they buy them from vendors. For many years they did make their own parts and their quality control was impeccable. In the interest of downsizing the number of hourly union employees they slowly started “spinning off” their parts manufacturers and bought their parts. Now the manufacturers don’t have corporate looking over their shoulder so short cuts to improve their profit result in poor quality control and the customer pays for it in the end with warranty work like this where their truck is out of service at least a day.

      1. You’re right that GM (and all the other car companies) get a lot of their parts from suppliers, they are made to the specifications of GM. Seems like a lot of the problems originate with the cylinder deactivation system. So if there is a way to disable that without affecting the warranty I would do that immediately. The money that you save in gas can’t possibly compare with the money you possibly will have to spend later.

      2. With all this voodoo technology trying to get more mpg is killing many manufacturers. All my Chevrolet 5.7’s have been bullet proof for decades long before variable timing, active fuel management, and displacement on demand. Now add the offshore savings of unknown vendors and we have a disaster. A group recently started a class action lawsuit against GM over this lifter issue and it’s going to be interesting on how it turns out.

        1. I have had three variable timing engines with all of them getting really great mileage but I also had to do the engine rebuild ($7000) on the last 6.2 engine at 90,000 miles with a great service record. I will not be purchasing another GM Pickup because of the way this issue was handled.

    4. I just experienced this on my 21 Sierra, @ 4300 kms
      Symptoms: truck had a few backfire’s (in catalytic converter)
      Warning light: service ESC, service parking brake, service engine blinking, then went solid then went out.
      Took the vehicle to dealership, and was told it was a bent pushrod and they would fix it under warranty, it was this article that made me insist on both banks being serviced, they only wanted to do one side at first, after a call to gm care, I thought my concerns where going nowhere they said they would only replace the defective part and not both banks, I mentioned the article to gm care! There response was it only applies in the USA ( I’m in Canada) I told them well you just lost a customer, dealership called next day, and the are doing both banks!

      1. My 2021 5.3 lease is ending. I did have 1 bank of lifters replaced. I now have 34000 on the truck. I am not having a problem but I am told by the dealer that for 495 you can buy a 100,000 mile warranty for powertrain and it will add another 12 months onto your bumper to bumper warranty for a total of 72 months. Think I may do this since it seems better than after market extended warranty prices. This is all through GM, not some aftermarket market. Any Thoughts?

    5. Today the dealer replaced one bank of lifters on my 2021 Yukon AT4 with the 5.3 L. Over the weekend the lifter on the no. 4 cylinder failed and bent one push rod.Truck runs fine but Im very disappointed this can happen to a $77k truck with only 10,000 miles.

    6. I replaced the engine on my 2015 Sierra at 101,000 miles after the cam was scored. I installed a catch-can and an AFM disabler. No noticeable difference in mileage best mileage so far 22.4 and 13.0 mpg towing a travel trailer. At the current prices of trucks, replacing the engine was the cheaper alternative. More power and no more trans shift going from 4 to 8-cylinder mode, With the disabler, remove it several days before going through inspection as their equipment won’t read anything and it will fail, then plug it back in after.

      All newer engines are GDI. Not like the old port injection engines where fuel would wash over the valves, The GDI engine fuel is injected under the valves, so you wind up with carbon buildup over time. Valve cleaning additives won’t work, if the fuel doesn’t reach the top of the valves, how would the additive get there?
      Because of that, the induction system, especially the intake valves, are more susceptible to deposits that can rob the engine of power, waste fuel, and cause oil burning,

      To keep your car’s engine running smoothly, GDI systems should receive a Major Fuel Service every 31,000 miles.

    7. I had a 2016 Yukon denali I had issues with a collapsed lifter at 32000 Km’s it’s was fixed under warranty now at 62000 Km’s the dealer has to put new cam shaft lifters and General Motors won’t cover it because my warranty is up and it has hardly any Km’s on it so I won’t buy another Gm product anymore I was treated like sh!t from General Motors first there were going to fix after the work was done General Motors called and said they won’t cover it so beware of buying a General Motors product.

    8. Just fixed my 2019 Silverado crew Lt w/ 5.3lt. 1st- 8 speed tranny issue in October – $750.00 + tax, then the lifter went in the beginning of December, which damaged the camshaft -$7,950.00 repair (in B.C. Canada). As I was out of town I had to rent a truck – $986.00. So at 3 years old the truck repairs cost $9,700.
      I always Dealer maintain the vehicles and was out of warranty by 25,000kms, GM said too bad.
      These items should not be a problem in a 3 years old vehicle,
      I will not buy a GM vehicle again.
      I would advise not buying GM anything until they address the issue.

      2. Who said “no help”? If it was the dealer, call GM direct, as per your owner’s manual. If GM said no, the contact your government for assistance. In the U.S. it would be NHTSA or similar. Or Better Business Bureau. Not sure what the Canadian equivalent would be but there must be one. Last resort is an attorney but they are more trouble and expense than they are worth.

    9. I just had my lifters go bad on my ’21 6.2L AT4. The GM dealer replaced the 16 lifters, camshaft, AFM valve body and supporting parts without issue. The article above states that they should issue a 5yr 100,000 mi warranty. Dealer claims they no nothing about that and offered a 2 yr unlimited mile warranty. Is there a GM bulletin that references this 5 yr warranty?

      1. My 2019 is currently sitting at the dealer . they are offering 2 year unlimited warranty. but with a $7800 price tag for a cam and 16 lifters, I think Ill just fix it myself

          1. One quart every 2000 miles in 1953 maybe. I change oil in my ’11 5.3 every 3000 miles, I use high quality synthetic amsoil and use ZERO oil in those miles. GM has apparently dropped the ball in the latter years with their overpriced vehicles.

            1. There is no reason to change your oil that often unless you drive 3000 miles a year. You are wasting the oil and politing the environment. You should be following the change oil soon indicator on the vehicle. Don’t be a fool.

I didn’t have any more trouble with the engine, I traded the truck for a 2023 Silverado just like old one LTZ Z71 1500 5.3 10 spd transmission only have 900 miles on it, so we shall see if this one holds up.

I am not having a problem but I am told by the dealer that for 495 you can buy a 100,000 mile warranty for powertrain and it will add another 12 months onto your bumper to bumper warranty for a total of 72 months. Think I may do this since it seems better than after market extended warranty prices. This is all through GM, not some aftermarket market. Any Thoughts?

        2. Retired from GM a few years ago. And at that time I owned a old 2005 Ford F-150 with 300,000 mile on it and NEVER had major engine or transmission work done on it. Found that the frame started to have rust issues and I decided to Retire it. At the time GM ordering a new truck or finding one on the lot was hard to do. So found a one owner 2017 GMC Sierra with 128,000 miles on it. Very clean truck. Only to drive it about 800 miles and started having lifter trouble. Took it to a GM dealership to have it repaired at $1600.00. 600 miles later I’m back at the dealership with the same problem. Only to have GMC corporate office tell there nothing they can do for me. Had more help from the dealership than my so called GM family on being an GM employee. Don’t waste your time on calling GM, took 2 weeks for them to call back, only to say we’re sorry can’t & won’t help you

    2. My 2021 Yukon is in a service department for a week and 3 days now waiting for the parts to repair the lifters etc…my Yukon has 5,000 miles on it. We went up north in Michigan for our 30th wedding anniversary and had to leave my car at a gmc service department and have our son drive 4 hours to pick us up because there aren’t any rental cars available!!

      My service tech is still waiting to see a routing number which will tell us the parts have been shipped, did I mention I’m a Realtor and use my car for work!!!

      My first week of buying my Yukon I noticed the second row bucket seats both rattled really bad. Took it in, 1 week later I received it back to have the driver side seat still rattle after 2 days of driving it. The service department said they used shimms on that seat and they must not held…so after a week of the service department convincing gmc the 2nd seat needed a new frame like the first one they fixed. Found out gmc didn’t approve for the 2nd seat ti receive a new bracket. They finally did, waited 3 weeks for that to come in and the lifters failed and is 4 hours away. When I get it back I have to send it back to have the seat bracket/frame replaced!!! That is a 3 day event!!!!

      Do I have any recourse for having so many issues!!!

      We buy new cars rather than a used car to avoid problems. WTH!!!

Well if anyone knows if you have a lifter go bad it usually damages the camshaft, but GM is only replacing lifters and sending customers on there way. What gets me is GM has been dealing with this issue since around 2008 or 2009 and they cannot find out the problem. May have to trade for Ford or Ram.

Anyway it cost 250 basiclly for an oil change. I got the air conditioner fixed for 250 bucks at another garage. I have put on 5000 klics since tyhe “9000 dollar diagnosis” and the car is running great. the question is “why arey they so thorough on someone elses’ dime yet overlooking factory defects?’…hmm kind of makes you think…maintain

    4. Valves, bearings, pistons, rings, gaskets, are made by vendors for gm and everybody else. The vendor had a bad run on valves. gm’s quality control receiving unit which takes samples of vendor sourced parts to check for specs and quality did not catch the bad batch of valves.

      This is a relatively uncommon occurrence with manufacturers but does occasionally occur.

      It’s amazing how many parts on vehicles and equipment are vendor sourced these days. Caterpillar in fact sources their smaller diesel engines in their entirety from Kubota and wholly owned Perkins. They
      paint these engines yellow and put a Cat decal on them.

      Caterpillar had a run of bad engine crankshaft bearings from Clevite about 40 years ago. Cat’s quality control receiving did not catch and it was a warranty nightmare. Also created extreme replacement part shortage.

      1. The problems all stem from the fuel management systems they use on these engines that shut down cylinders to save you one MPG. I put in a unit that disabled AFM on my last Silverado. 150k miles no issue, no oil consumption no failures. Damned frame rotted out though so had to trade it in. Overall GM quality is definitely slipping badly. It’s inexcusable given the price of these vehicles.

        1. I agree frame rot in ALL the truck makers not just GM is inexcusable.That is why you have to clean the frame and use fluid film or something similar every year or two before the frame can start to rust .I would spray the frame as soon as I got the truck home from the dealership. And if you keep it up the frame should last as long as you own it. Shouldn’t have to but that’s reality.

I know this for a fact as my fired owns dealership and made a wise crack about how much dealerships customers off on new cars. He showed me what he’s paying and profit made from. Sales for the month. He said its his service department is where the money is at. He also said he makes thre to four times the profit off from selling used cars. Why not just sell used cars I asked him. It wouldn’t be as profitable and couldn’t get nowhere near the amount of service work he gets.

I have a theory what caused the problem, I left work no warm-up the oil pressure was up because oil was cold in less than a mile I jumped on it to pass a slow semi and pop, tick tick tick, engine light and big time rough engine shaking whole truck. Had it towed to dealer in one day they told me the bad news they replace only the two lifters on the offending cylinder I had major issues with the repair decision they promised all will be good. I now have 147.000 miles on the fix but I defiantly let it warm-up before I get foggy with the gas.

    This way of doing business can be both profitable when it works well, or literally damn cost you the business when it fails, the problem is the “powers that be” (ultimate controllers) within the GM Hierarchy, like the politicians in every form of our government do not see a problem doing things like this, they are never intimidated or have to answer directly for their inactions, they are always blaming those “downline” from them and never have to face an immediate repercussion for their misdirected ways of handling things, including huge amounts of money or the failures of their products.
    Bottom line, if everyone who was responsible for maintaining the integrity of the business or government through their own personal actions and were made responsible for their actions and the outcome of their job position, things would go a lot differently at General Motors and within our Federal Government as these two “Giants” are running “neck and neck” when it comes to taking care of business and the eventual outcome of the way they both “do business”.
    Love ’em or hate ’em…they’re here to serve you, how they are perceived and whether you accept or reject them both, are dependent upon how you are treated after you either purchase their product and how the product works for you and whether the government actions taken almost daily either makes you happy, or literally pisses the hell out of you.
    You’ve got choices, never buy another GM product again as there are lots of choices out there for you and within our government, you’ve got choices too…you can literally vote that POS out of office or raise hate and discontent, and if you do that…don’t give up until you feel you’ve been satisfied with the results. Isn’t it amazing living with choices in The USA,

  23. When a customer invests $60,000 for a vehicle they should not be getting cheap Chinese made parts, especially life blood parts such as valve lifters. The newer DFM/AFM engines require that the cylinder heads be removed to get the lifters out making the labor costs to do so that much higher. That said, nobody wants half of a repair done and their expensive engine left with a high probability of failure. Shame on GM for having contempt for the customer

  25. I’ve seen several GM Yukon’s, Silverado etc. in my shop that had lifter problems going back to the start of the LS cylinder deactivation start of production. It generally cost $4-5k to repair properly, which often includes a new camshaft. GM introduced cylinder deactivation in order to meet fuel mileage and emissions targets while being tested on the EPA test cycle. It’s not there to actually benefit you, the customer, but rather to meet an arbitrary requirement decided by some unelected government worker.

  28. The new GM V8 engines all have roller hydraulic valve lifters, as a mechanic I’ve seen some engines with lifter noise. the motor oil wt required is 0 wt 20 motor oil. in warmer climate like Arizona after brake in period I’ve switch to 5w20 and has show an improvement in performance and quiet and much less wear even in engines like the 5.3 liter that have over 150,000 miles.As you put miles on the engine tolerances change, even engines that consume oil.

Wherever I do a lifter repair I change the oil management unit.

  31. I’d be awfully nice that everyone read the TSB and the article. It is not a lifter problem, it’s a valve spring problem that damages the lifter. GM engineering want the springs returned, not the lifters.

  32. This has been going on since 2007. At this point you can’t blame the parts manufacturer. This is GM and the US government. “Bail out” our government wants hard earned tax payer money to help bail out car manufacturers cause they’re to big to fail, but in return this is what consumers (tax payers our money from the get go) has been dealing with for 14 years. USA judges keep throwing out law suites GM expects loyal customers to keep buying junk.

  37. I had my 2016 C7 Corvette in the Dealer ship to have the rear view mirror replaced as the silvering on the back was coming off. Have an extended warranty that I purchased when I purchased the car. The mirror was covered with a $100.00 deductible, Labor & parts $285.00. On the way to the dealer the service engine lite came on and they found multiple misfires on cylinder 5 & 8 ended up have to replace 2 sparkplugs and wires. $385.60 parts & labor. Not covered on my extended warranty as they are considered items that can wear out. Last time I remember purchasing sparkplugs was in 1994. Sure hope I don’t have this Valve Spring and Lifter problem. GM should just bite the bullet and take care of this problem for their customer as not doing so will come back to bite them in the ASS!

  39. I first experienced the problem on my 2015 6.2 liter at 45000 miles. They put a band aid on it hoping it would last until the warranty expired. Just after 60k the lifter, push rod and cam went on the opposite bank. 7k out of pocket to repair. It has failed twice more on the the side that they fixed. The original side has not failed again as of yet . GM recalled all of the old lifters and push rods . Replaced them in on side of my engine , leaving the original equipment on the side that originally failed. Why wouldn’t you replace them all is my question if you’ve had as many problems as mine has ?

    Reply
  40. It is my understanding from research it is not failing lifters initially, it is valve springs breaking causing the lifter failures. Also try buying auto parts even name brand top of the line parts are failing including lifters and cams. This is not isolated to car manufacturers we have a quality crisis in the U.S. with automotive parts across the board.

  41. This problem has been happening since they came up with this poor excuse of a system. It happened on my girlfriends 07 tahoe with the 5.3l. So I did the smart thing and replaced the lifter and gutted all of the solenoids that activate the system. Then deactivated the system in the ecm. It’s been 2 years and I haven’t had a problem with it since.

  43. If you have a noisy lifter problem why are you gonna replace one bank and not both? 8,000 miles is way too soon for this type of repair. Although cylinder valve ‘deactivation’ may not be popular I doubt it plays a role in loud tappets. Cheap lifters, thin oil, and excessive heat most likely at fault. 5.4 L engine is crap anyway. ASE Tech.

  44. This issue has been going on long before the 2019 vehicles, I had the lifter failure in my 09 Silverado LTZ with the 5.3 at 18,000 miles, It was repaired under warranty and according to the service manager not the first one that had been to that dealership for the same problem. I have had 4 GM trucks since that one and never had the lifter issue with those trucks although I did have transmission problems in my 21 trail boss at 14000 miles.

  45. At least GM is giving the dealers a little flexibility to hopefully fix a customer’s vehicle. With Dodge, the dealers try to tell you it’s normal and try not to even touch it. If you persist enough, they will replace the lifters, but most likely that won’t fix it. When you continue to have lifter noise at start-up and even at idle, they will again tell you it is normal. They will bring in a district rep who will listen to the noise as well as all the videos you ha e put together of excessive lifter noise on start-up and even continuing for a minute sometimes several minutes. The district rep will then tell you it is normal and they all do it and refuse to do another repair. Then when you hit around 70k miles and the warranty is expired, you get to pay for a cam and lifters due to a failed roller and worn out cam lobe. At least GM is giving the dealers some options. As with the Dodges, not all of them make the noise, I wold say a far fewer percentage of GM V8s have lifter noise than Dodge Hemi. In all reality an engine replacement will take care of any problem that could possibly cause a lifter noise, as long as you don’t another defective one as a replacement.

    1. Chrysler dodge, they do tell you its normal. Had a engine knock with 1700 miles on new truck and it wouldn’t idle without purging. They tried to fix it numerous times at several dealerships. They kept saying its normal. I told them they 100 percent right. Normal for Chrysler to sell defective vehicals with low quality parts. Whats also normal is that Chrysler has always been hanging on like someone on life support. 1980s is perfect example of Chrysler product quality!!! Back in the 70s early 80s you couldn’t use Chrysler if it was raining and if you could get it to start the first puddle you hit youd be calling triple a or a tow truck!!

  48. Sooooo….. short background….
    Collapsed lifter #4 cylinder at 3800 miles. Lifter and bent push rod replaced.
    Collapsed lifter #5 cylinder at 5400 miles. Lifters on entire side (8 lifters) and bent push rod replaced.
    Collapsed lifter #7 cylinder (on other side) at 8900 miles. Lifters on both sides (16 lifters) and bent push rod replaced.

    GM acknowledged problem with in-stock lifters and had all service depts send back stock of ‘bad’ batch. From reading and watching some videos from seasoned mechanics, I feel certain engines were assembled with poor quality lifters, GM has realized this, pulled the parts and are now advising service depts to replace ALL lifters with quality stock to avoid additional occurrence of this issue. I just picked up Suburban yesterday from this third go around and the service mgr told me “This engine has been repaired three times now. If I were you, I’d contact GM about this.” I told him we already had an open case since the first incident.

    UPDATE:
    Drove away 2 weeks ago with all new lifters (16 of them). Was again out of town for work, sitting in a parking lot with engine running for about 20 min. Engine started to feel kind of sputtery so I turned it off. Five min later started it to drive away and continued with sputtery feel, misfiring, ESC, Traction Control and Check Engine light came on. Ended up getting it towed from Raleigh to CLT, NC. That was Wednesday at noon and now, Friday evening, they still haven’t looked at it. We are totally, completely done with this car! It makes me soooooo sad that Chevrolet made this beautiful, smooth, comfortable car but put a piece of junk engine in it!! We’ve spoken and emailed the dealership where we bought it (first time we’ve contacted them about this as we bought in MD), have emailed GM yet again and are now looking into a lawyer. I REALLY THOUGHT THAT AFTER ALL 16 LIFTERS BEING REPLACED WE’D BE GOOD!!! But now I just am going to work on our lemon law and getting every dime back from this car’s purchase. Then, I’ll get a 2023 Toyota Sequoia. Our GM days are completely over!!!!!!!

    NO ONE ever offered me an extended warranty letter, a new engine or implied they’d spoken with any one higher up.

  49. I will say this again that I posted earlier. The last I knew all GM lifters are still made by GM at their GMCH Plant at 2100 Burlingame Ave in Wyoming MI. They have been making them their since the 1940’s when it was known as Diesel Equipment Division. Name changes started around 1980 but for most of time it was a GM Plant except for a short time it became Delphi until back to a GMCH Plant. Just sayin as the Lifters are not made in China or Mexico yet. Again just sayin, these lifters are Made in the USA the last I was aware of. I wish you all good luck as this problem is definitely holding me off from buying a new GM 6.2 P/U truck.

  51. Purchased a 2021 GMC truck in April, it has 6k miles on it now, it broke down on the way to a family vacation and we had to have it towed back home. It has now been at the dealership for two weeks and they are still waiting for parts. They say they do not have enough loaner vehicles right now to supply us with one. When I ask about an extension of warranty after this repair, the service advisor told me he was sure we could purchase one. When I asked about a phone number to call General Motors, he said there was not one that he knew of.😂😂 Wow.

  64. I bought a 2021 GMC Denali with the 5.3 in late March, in August with 12k miles traveling with my family and travel trailer I have the horrible knocking sound which come to find out were lifter issues. In the area of Northern Idaho both dealerships that Roadside Assistance was going to take me to couldn’t look at the pickup for dang near 2 months. Well, that wasn’t going to work due to us having to check out of the rv park in a couple days. Rather than have me towed home they suggested I try and drive it home. We made it, thank goodness. Needless to say that was quite the drive home, on pins and needles basically! I took truck down next day to our local GM dealership where they knew initially it had to be lifters. As I mentioned with 12k miles they thought GM would put a new motor in, however GM miraculously “found” some lifters that were supposedly backordered and dropped shipped them to the dealership. The local dealer fixed the “left bank” of lifters and gave it back to me Aug 27th, questioning how long before the other side did the same thing why wouldn’t they go ahead and do the other side. Their response was that GM only sent them enough for the left bank. On 9/2/21 as I was driving downtown and HERE WE GO AGAIN!! The lifters, I assume are going out again! This time the pickup was running awfully and worse than the first time. Now their is NO rental cars available, ugh at what point do I say hey lets just cut ties with this pickup and look for the 1/2 ton Diesel. haha

When you build CRAP , it takes the General a truck load of money to fix the Crap. Even back in the Hyundai Pony days, they upped their warranty programs. They offered longer warranties and learned to make them better. Now on the other hand those of us that would rather buy North American built are switching to other NA brands. But the General seems to know their “base” will continue to buy CRAP.

  86. I like GM. Sure there have been some Turds that I’ve bought and quickly got rid of. The 2012 Buick Enclave, what a good look comfy riding vehicle. Too bad it had a awful engine and transmission. Gone after 8 months. 2011 Chevy Tahoe what’s up with the 5.3 turd of a engine? Gone after it started to tick. I still have a few GMs nothing is perfect. Still have our stock that’s doing well. Everyone let’s get along. 😃

  90. LOL Talk about Debbie Downer. The price we are paying for most New Vehicles today should include quality. It’s not that far fetched to think or want the new vehicle I or you purchase to last a few trouble free years. The maddening part has to be what the Generals top dawgs pay themselves to produce CRAP. The other thing is we keep buying their CRAP. Isn’t the definition of CRAZY doing the same thing over and over again but expecting different results ?

  91. Ditto on that. But it’s happening with just about everything. I’ve read where new rvs are falling apart and functional things stop working on the first trip. No one cares, there is no quality workmanship, no personal pride in their work, profit, no matter what it takes.

  92. Is it time to make the brass accept the notion that if you build CRAP you will lose your perks, your bonus’s maybe your job ! Maybe work on the dysfunctional levels of Government to push for Quality over Quantity . Create a watch dog WITH TEETH to legislate full dollar refunds , when they sell us CRAP. That’s sure to affect the bottom line and their personal bonus’s. Problem is by the time that happens we’ll be in electric self driving cabs. Just say n for a “friend”. Really the only option that will work for us is S T O P buying new and get a warranty with the used one. Or keep the ol clunker going another year. If we do not buy new … They will notice.

  93. I had my lifters fail on my truck at 3600 miles 2021 AT4 CarbonPro Edition 6.2

    Took over 6 weeks to get my lifters replaced because of new lifters being on backorder. During that time I open a case with GMC to get the dealership to find the parts.

    GMC offered me two options.
    1. Sell my truck back to GMC for what I paid for it.
    2. Repurchase a new one.

    Considered doing the repurchase but I have been waiting for over 2 months to hear back from a dealership that wants to take the deal of me getting a new truck.

    I been driving on the new lifters for about 3k miles now. I’m considering just taking the money and moving on, I spent 70k on this truck it’s a very uneasy feeling to know that your engine failed such low mileage.

    Replaced lifters cause enough to call the truck bad and return it?

  95. First this is an absolute mess what has happened to everyone with these GM lifters and how it’s not being handled by GM. With all the excuses the dealers are using including shortage of being able to get replacement GM lifters, it makes a person want to insist to GM and the dealer to use a hopefully high quality aftermarket stock replacement lifters. There must be aftermarket companies? Crower? Eaton? Rhoads? I’m not up on the current aftermarket lifter companies but it might be worth considering, especially since a lot of you owners are saying after repair number one, the lifters go bad again. I wish everyone the best with this unacceptable garbage quality situation.

  117. My son came home to Texas on leave last Christmas and traded his 2019 Ram 4×4 for a 2021 Silverado and drove back to Phili. In May this year he came back to Texas from Phili for his sisters graduation and he never got past Roanoke Va. before his engine failed.
    They gave him a loaner and he drove back after his leave was up and picked up his truck. Again he has made the drive from Phiili to Texas for his last Christmas before he is reassigned to Korea and made it 6 hours past Roanoke to the middle of Tenn and once again his engine has crapped out.
    I guess that Chevy engines are not suitable for cross country driving. He should have kept his Ram. I am on my 4th Ram since 1997 and have no issues in over 100k each.

    I have 21’ Denali, @ 8k miles pulling our travel trailer for a quick trip the left bank goes out. Bring it in to my local GM dealer, they have it for 7 weeks, I hook up to trailer again to deliver to some friends for a weekend and the right side goes out. Return to local GM dealer where they end up doing right side, wish they would have done that originally butttt NO, would never allow that to happen. I got the pickup back this time in about 2.5 weeks.
    Now, cold starts in the morning is a pretty active “ticking” that I can’t pinpoint. Anyone else having continued issues??

  129. My lifter failed on Cyl 1 in a 2021 Suburban. I think it’s total BS that they will only replace one bank of lifters. The GM mech told me chances are one will fail from the other side. This puts my family at a safety risk as we’re driving a new vehicle that has a know failure major failure issue. Why the F wouldn’t you just replace the other side while you’re already in there? I called GM while at the dealership and they wouldn’t do anything more. I have bought 14 Chevy vehicles in the last 6 years 4 suburbans , 2 Tahoes rest service trucks and they could care less. Well as far as I’m concerned, I will care less too. I’ve always been pro Chevy and buy American and this is how they treat their loyal customers. NOT ANY MORE. Should have done what’s right.

Covered by warranty. That was all they did. Vehicle now has less than 75,000 miles and the entire engine needs to be replaced. The lifters on the other side went out. Camshaft almost completely destroyed. I’m looking at nearly $10,000 here. There is a class action lawsuit filed I believe in New York on behalf of 5 owners.

  136. I was told when my lifters went out on brand new GMC Sierra 1500 Denali with the 6.2L V8 L87 gas engine (about 5000 miles) that it was because of how I was driving the truck. Long trips on flat surface roads caused the truck to drop out 4 cylinders for gas savings. The cylinders continue to leak oil by and if a prolong stretch of road there can be a considerable build up. Upon engaging the cylinders again for climbing a hill the inability to compress a liquid causes damage to the lifters. My dealer advisor advised me to add an aftermarket chip to avoid the gas savings mode but take off before servicing to avoid losing warranty. Since adding I have not had a problem with lifters. However, now about once a month my onboard computers crash (everything stops working) and I have to disconnect the battery for a minute. Probably bc of the chip. Wife wants me to sell it but I sure like the ride. Anyway, just FYI.

    My 2019 Silverado 1500 RST 5.3L L84 is currently sitting at the dealership having the engine torn down (at MY expense) and they’re estimating $3k-$7k in repairs to fix the same issue.

  140. Always been a GM guy. I have bought 6 new Chevy trucks since 1984. Four of the six had the 5.3 engine, no problems out of the first three 5.3s. My 2021 LTZ, the nicest dream truck I have ever had, is now in the shop with this problem. I am shopping for a different truck, probably Toyota. I really don’t care for the Tundra but it appears to be bullet proof, more so than the Rams, Fords, and GM trucks I read about. I can’t understand why GM would knowingly continue to crank out these v8 motors, since 2019 with this problem so prevalent on the DFM models, when their truck sales have been the only thing that has kept the company afloat for a long time. If they can’t make a dependable gasoline motor as long as that technology has been around, how will they ever compete with tomorrow’s technology? As a long time customer, now an ex-customer, we deserve more than a big FU from GM.

  141. With all the mechanical knowledge both here and at GM Engineering has anyone pin pointed the CAUSE.
    NO Guessing, Suppositions, Made in China BS. THE FACTS? Seems to me the valves are somehow staying open and lifters are bending pushrods. That is likely not the case however.

    Reply
    1. The cause was explained in another thread on this problem. There is a check ball in the bottom of a hydraulic valve lifter. Behind that check ball there is a little spring and together they regulate the amount of oil flow that makes the lifter adjust. According to that thread, the vendor that supplied those springs did not heat treat them properly causing the the lifter to collapse under load. The lifter components are all made in the US. Go look it up.

      Reply
      1. If the Lifter ‘collapsed’ there would be less force/distance for the pushrod to travel. Valve ‘lash’ is increased giving more clearance. Valves must somehow be sticking in the guides or hitting pistons to force the Pushrod to bend. My original post was in error. Valves must be staying Closed, not Open to bend pushrods.

Long end of it we sold my wife’s SUV and we decided to put a new engine with a warranty from GM. 3 year 100,000 miles. So for a decent price she now has a rock solid suv. The new engine has the the same crappy cylinder deactivation as the last one. Fingers crossed

  153. I have a 2005 Chevy Suburban with 148,000 miles. It is the GMT-800 platform that is bullet proof. I put 120,000 miles on myself. Never had a single mechanical problem. I’ve only had to change fluids and brake pads. Oh yeah, I needed to get the A/C charged twice because I live in Florida. I’m also a fanatic about oil changes because I change them myself every 6k miles or 12 months. I was just getting ready to buy a new SUV before COVID hit. Now I think I will just keep it and put another 100k on her.

    I miss the old GM and now the old Toyota.

  154. I paid out $8400.00 on my 2019 Yukon for the Lifter/CAM problem. I contacted them. The first person I talked to was ugly with me and then I called again and talked to a decent individual. They sent me a check for $2562.00.

  156. Our dealer on a 2019 6.2 silverado only replaced the lifters on the cylinder that was having problems at about 70,000 miles and then we had another cylinder go down at about 94000 miles. At that point the engine had been so damaged that it took $7000 in engine work to get it back up and running again. We were never aware that any banks of lifters were to be replaced with either incident or that the warranty from GM should have been extended. Our dealer kind of gave us crappy service.

  157. I have a 21 gmc which they did one bank but I also bought a 100k extended warranty just in case from the dealer. I now have 44000 on it and keeping my fingers crossed. I had to pay to have it certified first and then I bought the warranty.
