Another class-action lawsuit has been filed against General Motors over valve lifter-related issues in Cadillac, Chevy and GMC vehicles equipped with certain versions of its Small Block V8 engines.
According to Car Complaints, a total of nine plaintiffs filed this class action lawsuit in the U.S. District Court for the Eastern District of Michigan. The lawsuit filing claims the valvetrain system in affected Small Block V8 engines, as well as the Active Fuel Management and Dynamic Fuel Management lifters, are made up of sub-standard materials that can cause them to fail prematurely. The suit also says the lifters in affected engines were installed in an incorrect position in the lifter guide and do not always conform to design specifications. Plaintiffs claim their vehicles needed frequent valvetrain maintenance, including “more frequent oil changes, engine flushing and cleaning and/or replacing the valve lifter oil manifold and its filter at regular intervals.”
Plaintiffs also accuse GM of using equally as defective parts to repair customer vehicles with, ensuring the valvetrain problems persist even after the necessary repairs and maintenance have been performed. GM also offers a component coverage program to cover the repair costs due to the widespread nature of valve lifter problems in its Small Block V8 engines, however customers are only entitled to component coverage after they’ve had their vehicle’s valvetrain repaired twice previously – something the plaintiffs are also not happy about.
This class-action lawsuit includes vehicles equipped with either the GM 5.3L L83 or 6.2L V8 L87 engines, or the older 6.0L Vortec V8 L96 motor. This lawsuit also includes vehicles equipped with the performance-oriented 6.2L LT1 V8 engine in the sixth-generation Camaro and C7 Corvette Stingray and C7 Corvette Grand Sport, along with the supercharged 6.2L LT4 V8 in the 2016 to 2019 model year Cadillac CTS-V and C7 Corvette Z06.
GM Authority has received countless complaints from GM vehicles owners regarding valve lifter issues in certain GM V8 engines. This latest lawsuit calls for GM to issue a product safety recall to address the widely reported problems, however the automaker has so far only issued technical service bulletins instructing dealership technicians how to diagnose and repair these reported problems.

What is the actual percentage of “defective” engines. From what I’ve read there are thousands of complaints from 10’s of millions of engines. That still doesn’t seem that bad if that’s actually the ratio. I’ve read that there was thousands of complaint from ecoboost engines loosing valvetrains and hemi’s rounding cam lobes, but it seems only GM is getting sued all the time.
Did ford and ram issue a recall, or is GM’s number way higher than I think, or is GM just an easy target to sue?
Replying to cdnsolman: good point, what actual percentage of engines are actually affected? GM has spent millions on the Takata airbag recall, even though the number of Takata airbags that have failed in GM vehicles is actually ZERO.
I had a 2008 Yukon XL involved in the airbag fiasco. The dealership kept telling me, GM factory customer service too, that parts were not available. Sold it in 2019 still not replaced.
I bought 2 2019 Denalis for my business partner and myself on the same day. They were the 1st ones in town of the new update. He had a catastrophic engine failure due to the lifters at 50k miles, it was covered under warranty.… mine just failed yesterday. The quote from the dealer to repair is $10k. Between my business and my Youtube channel we have bought 8 Sierra Denalis in the past 4 years. We have had multiple brake vacuum failures, transmission failures, condenser failures, seat motors, step motor failures and now these 2 major failures… sigh… we have several Jags, Porsches , Audis, Corvettes and other cars on our channel… none of them are failing like these Denalis. But…. I do love to drive them when they are working. Whether we create a video about this for Youtube will depend on how the dealer handles this issue today.
Please follow-up on this blog so we know what happens I’m hoping that warranty covers your repairs.
Well, the trade in on my 2019 Denali with 80k miles was $42k, take away the $10k worth of engine repair and I guess that would put me around $32k net trade in. I discussed the issue with the dealer and made a trade on a new 2022… the identical truck, and they gave me $51k for my truck. I then bought a 100k mile extended warranty. So, I guess they made it right . Love my dealer and I know manufacturers all have their issues. GMC does need to step up their QC, but the driving experience in the Denalis is the best and the ext warranty does make me feel better.
The law suit should have been filed several months ago as late as November 2021. GM is stalling for time and does not intended to honor any payments or settlements deemed necessary. I honestly believe GM should stand responsible for the defective engines they producted and installed in these vehicles.
Try the body control module. It’s not expensive. That will fix some of the problem. The lifter issue is due to the 4 cl to eight cyl issue. It’s a bad design. You can shut it off with a 79.00 to 300.00 fix . It’s a module that plugs into the computer. It stops it from going from 4 to 8 cyl. It keeps it on 8 cyl. If the motor is cooked I’m afraid you need to replace it first.
Jeff, I did have mine programmed to turn it off, but it didn’t help. I had the extra warranty to 72K miles and it still broke at 74,400. It had the collapsed lifter and bent push rod. Dealership had it 8 days and still didn’t know what was wrong or so they said. I suspect they may have been wanting to get into my pocket as well for the $10K. I paid them for a tune up and carbon clean out for a misfire. So I had it towed back home to a reputable engine mechanic and he found the problem in an hour and a half. The total cost was $3100 to get it fixed and no guarantee it won’t happen again. I did not trade for another truck because I didn’t want the same problem with a new one. This is just a screwed up system GM has come up with and now they have it on the 4 and 6 cylinder engines. It is a poor design to try and satisfy the cafe standards for gas mileage. When it causes the customer so much trouble and the cost of repairs offsets the gas mileage, what have you saved?
I am dealing with the exact same issue, engine tear down lifters bad, extended warranty will pay for a rebuild ONLY.. – Dealer has had my 2021 Z71 Tahoe for the past 5 weeks- GM gave a “comment” of $3500 towards a new vehicle cash assist…because the dealer cannot locate an engine throughout the ENTIRE Country..terrible design and should be a recall- or MASSIVE CLASS ACTION LAWSUIT
I my self have a 2017 Sierra denali lifters just went 2 weeks ago the active lifters of course and effected my cam shaft my warranty is all up so it’s on my dime I’d have most of the issues you’ve had but warranty did cover most brake vacuum pump side auto steps sticking ect. But when it’s running perfect it’s one nice ride
there’s plenty youtube videos how to replace thise yourself. $200 in parts, 10 hrs to do it yourself.
I am a disabled retired vet. I am unable to do this myself, nor do I own the tools. I also cannot afford to trade for a new vehicle. So I drive the vehicle waiting for it to fail.
What about those in my shoes?? This is the second time GM has left me flat on a vehicle I’ve owned.
And please don’t tell me to buy a Ford, Dodge, or Toyota. They are all just as bad and all have their problems.
John, I too am retired and disabled. I sympathize with you and also am waiting for my Silverado engine to crap out. I looked into a trade and was shocked to learn that my truck with only 5,000 miles in perfect was worth $20, 000 less in less than 2 years! All we can do is pray that the class actio is effective.
We had the same issue with our 2016 Denali. It cost our family over $16,000 to get the engine rebuilt. There was no engine available to replace the one that blew out due to these very issues described in the article. Were you able to get anywhere with GM on helping compensate for some of these issues? This was a pretty significant blow to our family’s savings. We have five children under the age of twelve, which is why we purchased what should have been a very safe and reliable vehicle.
My Yukon xl had that lifter, camshaft failure do to the air fuel management system on these engines. My dealership located a new engine and after contacting gm complaint department they had the dealership split the cost. Engine cost me only 3k plus split labor cost to transfer equipment from old to new Engine and complete. Total was about 6k.
I’m out of my depth with the mechanical terms, here, but from what I understood the lifter failure caused something to fall down into the engine, which destroyed the engine, melted the manifold, and a series of other issues. Additionally, GM ignored our attempts to get help and we were told no engines were available…anywhere (due to Covid, of course). We had to get it rebuilt to salvage the vehicle as well as replace the other problems that were a direct consequence of the failure.
The air fuel management system deactivates half the cylinders under certain driving conditions. This is supposed to gain about a 5% better mileage. Unfortunately it leads to oil consumption, failed lifters which cause crank damage and engine failure. Gm v8 used to run forever but now with the add on fails way too soon.
AFM = Active Fuel Management, deactivating 4 of the cylinders in low-load conditions to save fuel.
Krystal, GM is not going to help in any way. I just commented about my 2015 Sierra Z71 having the lifter and rod problem. I asked for some assistance on repairing mine and was told they won’t help with anything after it is out of warranty. Between the dealership, towing fee, and an independent mechanic repairing our truck I was out $3100. I won’t buy another GM product or any other vehicle that has this junk on it, period. I know how you feel with children and having to break the bank for a repair such as this. Seems like it is all about the money and not about the hardship it causes on people for such an expensive repair.
Have a 2018 denali and had lifter failures at 50 thousand miles, vent failures and now waiting for the next failure. Truck paid for so.
Im dumping my 2015 Yukon Denali! Major eng failure at 30K and 58 K miles w text book + Service given. I have to keep buying a $3k Extended Warranty for (3 years) or risk paying $5-9K every few years…..and accept a dangerous, unforseeable roadside nightmare.
GM fixed once, my Extended Warranty paid 2nd time. I had 2 weeks ruined each time awaiting repairs. Yes, its a JOB+
leaving GM for Jeep Grand Cherokee Summit! Damn Shame…..
I am a GM tech and we use to see this frequently in the beginning of the year. The problem vehicles are built in Sept. Of 2020 upto March of 2021. I think they switched suppliers or slightly switched the design during the pandemic which caused these problems. GM has always had lifter problems on their V8s due to the AFM lifters always failing, but never this frequent and this soon in the engines life cycle.. If they got rid of the AFM lifters we wouldn’t see them ever. I don’t know the fuel benefits of it, but GM doubled down on them in their new design by having them for all 16 lifters instead of the 8.
If you turned the AFM system off, would that help the situation??
Yes. Many Impala SS, Pontiac G8, and Caprice owners delete the AFM/DoD system because they fail so much and there are tunes that plug into the OBD port. It’s the biggest flaw in their V8 sedans.
How do you turn off the AFM on a 2017 1500 Silverado with the 6.2L gasoline engine & a GMC 1500 Sierra with the 5.3L gasoline engine?
Thank you for your time.
The company is called Range Technology. I purchased it on Ebay for My Monte Carlo SS. Will need to take of before emissions test.
I bought 2017 surburban with the AVM engine with only 56,000 miles. Drove it to Florida and the engine went due to what was mentioned in this article. I had the vehicle for 11 weeks. The dealership said they haven’t heard about this problem with the engine. They are replacing the engine. I requested a a different engine which they refused to do. I requested that they shut the or disarm the AVM system. They said that they can’t do that either. If I had it done it would void the engine warranty. On top of that. The new engine will only be guaranteed for the length of the old engine warranty. So basically they are replacing a faulty engine with another Faulty engine. Needless to say. Not happy.
I bought an AFM DISABLER on Ebay for $115. Working great after 30 days! ( Dash says its ALWAYS in V-8 Mode now) No one knows for certain if it will ELIMINATE the issue…..but gotta sell or try. I have a 2 year warraty now, on the $5500 the Dealer charged to my Extended Warranty ( Warrantyt Co paid all but $100)
Good luck!
Thank you, Tech. This is the best estimate I’ve seen regarding the date range of this issue. And I hope it’s true so I can breathe easier regarding my new June ‘21 – built Tahoe.
Which year models are they talking about? I have a 2001 Silverado 2500 HD 4X4 with 6.0L and 2003 Suburban with 5.3L.
Alex, both of your vehicles are built before DOD/AFM was introduced. 5.3 liter in 2007 was the first year that the full size trucks/SUV had it.
Have you seen any owners be successful at getting both banks of lifters replaced even if the failure so far was found only on one side? My 2021 Yukon XL is in the shop now with the lifter problem, but the service team says they can only replace the one side. I have 11,000 miles on it, so it is past the 8000 mile cut off where they could have replaced both banks of lifters (according to what I read here). But I was wondering if there is a way I could push to have both banks replaced.
Also, do you know about how much it would cost for me to pay for the other bank of lifters to be replaced if I wanted to do that? If the dealer is not allowed to do it yet under warranty, I am curious what it might cost if I offered to pay for it so they can do it at the same time they replace the faulty bank. Thanks
I have a 2020 Sierra they replaced both sides and the camshaft at just below 50,000 miles
my 2015 Yukon went at 74K It was under Extended Warrany! ( thanbkfully) They replaced pushrods AND all 16 ifters. (Both banks) Gave me 2 Years unlimited mileage Warranty. Im gonna drive that SUV EVERYDAY! They only did both sides ( 16Lifters and the VOLM Manifold Oil device) because they dont want to see ME again until its OUTTA Warranty. Im trading in at 1 year 11 months!!~ Bye Bye GM…..
Warranty paid Dealer $5300. I had $100 deductible.
Best!
I have a 2020 Sierra they replaced all the lifters and the camshaft at just under 50,000 miles no cost to me. Everyone that gets one half done ends up back for the other try a different dealership that knows what they are doing
i just purchased 2922 silverado rst 6.2 will it fail also?
yes, they are still using the defective lifters
Ed they are not defective, the AFM and DFM are both bad designs. They both fail and if you are out of warranty GM is not going to help anyone with the cost of repair, period. I don’t know what they are going to do when the auto market crashes and they can’t sell those pieces of junk anymore. I hope they choke on them. They have had their way for to long with their customers. Now that prices are so high, interest rates are sky high, and payments of $1200 to as much as $1700 a month if you buy one, who can afford that? I can’t and I am not going to buy one or their overpriced EVs either. Buying and EV is a headache waiting to happen if you have to travel anywhere other than around town. I can see it now, GM and all the other manufactures will be sell rickshaws or bicycles before it’s over with.
Hope you’re right but remember they are the “too big to fail” guys!
Ihad Extended warranty on y 2015 Denali Failed at 74K. They did BOTH sides, 16 Lifters and VOLM oiling Manifold, because they DO NOT wabnt to see me again!!! Gave me 2 Years Unlimited miles. Selling or Trading at 1 Year and 11 mos ….
I installed an AFM DISABLER from Ebay at $115. I dont know if will solve issue but I dont want to be stucjk again!!!
getting ready to buy one tomorrow. Now I may not go thru the deal.

Ha ha ha ! YUP! Sorry….. No way to know when!! So damned upsetting….. The AFM DISABLER (Ebay $115) will help but NO ONE knows for how long!! 1k or 100k miles…..
Best!
i just purchased 2022silverado rst 6.2 will it fail also?
On 2021 Siearra I had the left bank failure at 14,000 the dealer replaced the lifters. Two weeks later the right bank went bad. The dealer replaced all the right bank lifters. I suggest you not trust the engine to be fully repaired. It is now well that this model year engine is not reliable.
I had the lifters fail at a little over 57,000 miles. It caused engine failure which was covered. They replaced the engine which took 3 months. I was 1300 miles away from home. I flew back picked up the truck. Drove less than 20 miles and the lifters went on the right side of a brand new engine. They replaced that as well. Not confident in gm engines any more. You need to become part of the class action lawsuit against gm in regards to lifter failures due to the AFM system. I have a 2001 surburban with 250,000 miles and I have had a work truck that failed at 325,000 miles. This new engines with the AFM systems have a lot of problems
2020? Mine is a 2016 Camaro 1SS and has the lifter problem now since 2018
My GMC Sierra is in right now getting cam and lifters due to failure it was built before Sept. of 2020, because I bought it in Jan. of 2020, I do mostly highway miles and it has almost 50,000 miles..was running fine but seemed fuel mileage was dropping some then on a zero degree morning after remote starting dash was lit up like a Christmas tree, check engine light, service parking brake, service ESC, and lifters popping under load if put in gear. They are also replacing the throttle body.
THEY will ALL fail on these damned engines!! Even the 22’s I hear! Some fail at 100 iles!! My 2015, 6.2 L Yukon Denali failed at 74K. Thankfully I had Extended Warranty!!! They gave me 2 Year Warranty on the work and parts. ( BOTH SIdes) They dont want to see me again…….. Warranty paid Dealer $5500………Sell or trade….
Have you had any experience with the replacement engines. I just bought a 2017 surburban had it 11 weeks drive it to florida and the engine went. The warranty is covering the engine. It has been 10 weeks and still the dealership has not received an engine to put in the truck. I am at a loss to say flute least I. What to do. No one can give me an answer to how long it will take to get the engine replaced. I have never dealt with so much bs. How long does it normally take to get a new engine. If anyone knows or knows who to contact to try to expedite this issue, I would greatly appreciate their input

Well I have 2017 that had 58,000 miles. Lifter went. Waited 3 months gm put a new engine in. Pickup the surburban and within less than an he and 15 miles the lifters on the new engine on passenger side went.
Hey Tech, you are just the one I want to talk to. I had the problem with my 2015 Sierra 5.3. Now they are putting this junk on the 4 and 6 cylinder engines. With all the problems it causes the customers, cost of repair, and loss of use of that vehicle, where’s the savings? Added savings in gas mileage is offset by the expensive cost of repair. I’d truly like to know how many vehicles have been affected by the lifter and bent push rod problems. On top of that how many engine replacements have been done? My 2013 had the oil consumption problem and I traded for this 2015 and I am asking myself if I made the right decision. My mechanic said it would help if GM had the lifter and rod inline with one another. He said they are at a slight angle to each other where the rod is pushing to one side of the lifter helping to cause it to fail. They are not geometrically straight with one another. I don’t know if this would help an already crappy design or not. I remember a time when GM and most car manufactures leaned toward less moving parts. Now it seems they have gone overboard the other direction. A simpler design has always been the best way to go, simple to fix, and more reliable. I would have to say GM’s reliability has gone down the exhaust tube. I won’t buy another one until I know they have brought reliability back into the equation.
No idea the percentage and I’m not Answering your questions but it happend twice to my wife’s Tahoe 19 months apart, pretty frustrating when your wife and child are stuck on a bridge… and then GM doest even provide a rental….
Bye Bye GM……. very sad. Went without a ride for 3 weeks!!!!
My 2008 Yukon XL with earlier 5.3 with AFM used to loose a little oil between oil changes, not a problem compared to the ones loosing alot at around 20k miles. Mine went 100k plus miles before lifter wiped cam. Tech said AFM causes oiling issues. Needed new motor. Small block chevy engines used to run several hundreds of thousand miles.
Trouble with Gm when you phone their warranty help line it is a joke. Had a problem with fuel injectors in my 2015 Chev Highcountry they paid 1/2 same with my 2017 GMC All Terrian they would only warranty for 1/2. In the USA they are covered for 10 years or 240 kms but in Canada you are on your own even if you have extended warranty not covered
Put a Range Disabler on my 2018 at 40kms now have 95kms and no trouble. I also use a oil catch can to remove the oil of the pcv valve. Does not affect warranty.
How many are not reported is what I’m wondering… I have a 08 Silverado with a 5.3L v-8 that spun a afm lifter at 59k… weeks after buying the truck… got it repaired to the tune of $3500 and it happened again with the new lifter within an oil change… this was with a tuner that had it disabled… I then just had the whole afm gear removed totally… so I ended up dropping over 5k on a new to me truck within 6 months of buying it having to protect my initial investment… GM knows nothing about it and I doubt they give a rats…🤷🏼♂️
They issued recalls and owned up to it. The reason GM is getting sued is due to them not admitting fault for these issues.
GM is incredibly cocky with recalls and admitting fault for faulty designs or parts causing issues.
I only know this due to the amount of extra money my personal vehicles have cost me, and General Managers advising I have someone other than GM fix it, due to their fix not being permanent. Just a new version of the same issue that will happen down the road.
They literally have a service bulletin addressing the issue and is completely fixed under warranty. So how is that not GM admitting fault?
Recalls are almost always issued by the NHTSA and not a manufacturer. The NHTSA and GM have determined that it is not enough of a safety risk to issue a recall, so it has not been done.
And I’d also bet it’s because it only affects such a small minority of engines that it doesn’t make sense to recall….but in classic internet fashion, you’d think that trucks are blowing up left and right.
People seem to forget that GM sells 500,000-700,000 of these trucks a year. A few thousand issues is par for the course for any manufacturer.
OK but they told me to go WHISTLE at 74K miles when it failed on my 6.2 L Denali $5500 for both sides repaired with a new VOLM (Oil Manifold ) I had EXTENDED warranty that I had PAID $3K for
3 years.30K miles, from GM directly. Oh, and NEVER USE THE CAR SHEILD thieves!!!
NO GM help offered even though it is KNOWN design flaw on a $71K Truck. Left without a car for 3 weeks too. Stuck on road with family……. THey only did both sides ( Service Mgr said) because they hope it lasts 2 years and then IWILL HAVE TO PAY MYSELF! Think again GM. You’re taking it in trade for something Electric…..
Sorry….bye bye GM
Exactly this. I’ve said this time and time again…people love to complain on the internet and make things seem way bigger than they are. And people especially love to hate on GM for whatever reason.
Remember, anyone can sue anyone in the US for anything…and claim anything in their lawsuit. I can sue GM for my car turning into a rainbow elephant at night and haunting me in my sleep, and if I get enough people to agree with me, I can even make it a class action lawsuit. Doesn’t mean it’ll ever get anywhere. 9 out of 10 class action lawsuits end up vanishing.
Also remember that GM has sold somewhere in the realm of 2.8 million of this generation of trucks, with probably at least half being 5.3 V8 w/DFM. Based on numbers on this forum and just extrapolating that, I’d wager that there’s maybe 1000-3000 engines that have this issues? That’s somewhere in the realm of 0.1% – 0.3% of total vehicles sold with this engine….
EVERY manufacturer has issues during manufacturing. Bad batch of parts from a supplier, issue with a line process, assembly error, etc.
If you have the issue, you just happened to get unlucky. Get the warranty service and go about your life.
It’s hilarious when people say stuff like “Oh I’ll never own a GM again or GM is so trash, blah blah blah blah” based on such tiny numbers. Have fun with Ford and Ram’s plethora of their own issues.
I have had gmc and Chevy truck for years. One work truck had 325,000 miles on it. I presently own 5 Chevy and gmc vehicle 8 cyclinders. I have a 2001 surburban with 250,000 miles and still runs great. I bought a 2017 surburban with only 56,000 miles only had 11 weeks and the engine went spent a lot of money on it . The ATV is the problem. Im sure after you spent a large amount of money on a truck and broke down in another state because the motor blew you would be singing a different song. Blah blah blah Gm is not going to admit they have a problem. Sad to say after this I may never buy another Chevy or gmc again.
When you’re the family affected by such a catastrophic mechanical malfunction in an expensive vehicle you purchased with the belief that it would be reliable and safe for your children, it IS a big deal that you 1. believe GM should be held responsible for, and 2. you don’t want other families experiencing the toll that it takes to get this resolved. It cost our family over $15,000 to get an engine rebuilt when ours blew on our way to a small holiday for one of our children’s birthday. We were stuck on the side of the expressway. Getting a replacement vehicle for a family with five young children was incredibly difficult. We bought this vehicle so we didn’t have to deal with these issues. Those tiny numbers are a HUGE deal when you’re the one affected by it. I’d love to be in your position without this issue and the perspective that you have, but, sadly, I’m the one that is in agreeance with this article and those trying to warn others to stay away from these vehicles so they don’t have to go through what our family went through.
I had my Yukon xl engine go bad because of lifter, camshaft issues. It’s the fuel management system used by gm to save a little on fuel,mileage that causes the oiling issue of these items. I spoke with gm complaint department and was able to have dealership split cost of engine to 3k instead of 6k. Not sure what you had done for 15k.
OK but they told me to go WHISTLE at 74K miles when it failed on my 6.2 L Denali $5500 for both sides repaired with a new VOLM (Oil Manifold ) I had EXTENDED warranty that I had PAID $3K for
3 years.30K miles, from GM directly. Oh, and NEVER USE THE CAR SHEILD thieves!!!
NO GM help offered even though it is KNOWN design flaw on a $71K Truck. Left without a car for 3 weeks too. Stuck on road with family…….

Sorry….bye bye GM
There are more. I have been fighting this issue for the last 4 years on my 2016 Suburban. I am almost at the end of my extended warranty and fear my engine will go out at anytime. It surges, burns oil and yet I can’t get it fixed.
Trade it in at GM……..for something Electric! New Blazer? No ore ICE GM for me! Maybe a Ford? God help me….
The law suit should have been filed several months ago as late as November 2021. GM is stalling for time and does not intended to honor any payments or settlements deemed necessary. I honestly believe GM should stand responsible for the defective engines they producted and installed in these vehicles.
Mine lifter just went out 2019 5.3L with only 68,000 miles on it. Caused damage to cam shaft as well. Change oil every 5k with factory recomended syntheic. Never pulled anything with this truck. Babied it! Now i have a $6,000 repair cost on a truck I paid $60,000 for less than 3 years ago. Not good and this is picking up steam. more and more complaints coming.
Mine is back in the garage for a 2nd time dealing with the motor.. 21 Chevy tahoe Z71. Its also had a few other Major problems.. This is such as POS vehicle for what we’ve spent, and GM isn’t recalling ANYTHING. What good is a seat belt recall, when my tahoe isn’t able to be driven. Its been at the dealership for 2 months now!!
Buy an Afm/dfm delete device that shuts down the system that controls the the cylinders shutting down to save gas and the engine shutting down at stop signs……the little stutter under acceleration goes away and the lifters don’t do the collapsing anymore. When the lifters collapse with the factory setup to shut down a cylinder they don’t pump back up as they should thats when pushrods and lifters start hammering each other and fail completely
Which of these ls motors tick (due mainly to the use of cheap plastic lifter trays to orient fragile hydraulic roller lifters in the lifter bore). All of them tick. Period.
Are we hearing about any issues with 2022 models? Specifically Tahoes?
Take a chill pill, Robert!
I personally predict a massive sweeping under the carpet coming. Instead of paying up and fixing the problem the General will just pay it’s lawyers.
You hit the nail right on the head.
I had the same problem in my 2021 Siearra. The right bank went out at 14,000. The dealer replaced the lifters. Two weeks later the left bank went out. I took the vehicle back to the dealer and they replaced the left bank. You should not be having this problem getting your vehicle repaired. Contact Lou Fusz GMC. Bridgeton. MO. I have the invoice to show you. Also my surpintine belt had to be replaced due to factory installment being improper. Good luck.
It’s for reasons like this that I stopped buying GM vehicles and switched to Hyundai. Hyundai has had many problems with some of their engines but they back them up. Three of my friends have had engine problems while out of warranty and still had the engines replaced at no cost to them. GM better learn about customer service before it’s too late.
Hyundai is the worst of any of the car companies at honoring their warranty.
My gf has a 2013 santa fe sport 2.0 turbo what a joke this vehicle is 28,500 miles on it wastegate problems take to dealer wanna charge 600 to replace that’s not happening i replaced wastegate was working fine Now the same problem arises Now the right rear window stopped working The fuel door doesn’t work anymore Its like one thing after another Sucks when you need to fill up have to pull manual release to open door All these problems really started after they did a software update for the faulty engine failures
YES….One guy had a New Silverado blow the ENGINE ON THE TEST DTRIVE!!!!!! Beware!!
Hyundai doesn’t build a truck so that doesn’t help.
You have to be joking. Google Hyundai Class action engine lawsuit. They aren’t giving free engines because they are a great company, they are giving free engines because they produced a crap product and got sued.
You better learn about buy American before t is to late
It’s worth knowing, gm owns Hyundai, Kia and Suzuki. They also have ownership in Honda Toyota and Saab. Isuzu is another where they share that ownership with Toyota. You haven’t changed anything
Class action suit: attorneys get millions. Plaintiffs get $500 off on a new GM car.
Sir, could you please put your shirt back on?
I have 2004 Chevy Avalanche with 5.3 and I have one lifter tapping. They said it would cost me more than $2500.to fix that is unacceptable and crazy to replace one damn part!!!!!!
Luck you, it cost me a new engine in my Tahoe, the truck was out of warranty by about 2 months when the engine came crashing down. Even then, I read hundreds of complaints online about it. There are lots of problems with these engines.
The problem is not the engine, it’s the the ECM that changes the motor from 4 to 6 to 8 cylinders. There is a module you can buy that changes it to full time 8 cylinders. This design rolled out in the 80s that was used in most 8 cyl cars,after the gas crisis of the 70s. It did not work well and was shelved. It was brought back out in order to comply with govt regulations of gas consumption. The market was trying to save the 8 cyl as an option due to pulling and necessary torque needed for construction and work horse loads along with speed. Chrysler and Ford, both are having issues and the Japanese market is no better. Buying a classic truck completely rebuilt and restored is the way to go. Gas consumption will be higher but repairs will be minimal. Try changing the ecm module on the newer trucks. You won’t be sorry. By the way, the 6 cylinders and some 4 cyl have these problems and more also. Changing companies will not help you. The classic truck answer is the way to go unless you opt for the ecm on the new ones
I just had an engine on a 2017 suburban with 57,000 miles the lifters went through the cam and they are replacing the engine. I requested a different engine that doesn’t have AFM system. They won’t do that. I requested for them to shut that system off that brings the eight cylinder down to four or six they refused to do that as well and they told me if I had modified after the new engines put in that it was going to void the warranty at this point I don’t know what to do they put in the same engine, new one ,that had problems back into my truck
Just buy the ecm yourself. I spotted a cheaper one. It plugs in under the dashboard it’s called pro range. If you don’t do this your subject to history repeating itself. You either want a good vehicle or a warranty. Just unplug it when you have service done if your worried about the warranty
I had the same problem with our 2007 suburban It left us stranded on the highway when the lifters failed. We bought a used engine with 60,000 miles ran it for eight months and it happened again. We did not know about that about the activation kit and they did not honor our warranty. Now I am in a Ford expedition that’s 10 years newer and I still miss my suburban. It’s sitting at my mechanics still wondering if it’s worth getting out from underneath this Ford payment to do another newer engine with a deactivation or DOD kit.
2013 Avy started getting lifter tick after 20k miles. All lifters and the damaged camshaft replaced under warranty. I will commend GM here – no hassles or complaints about doing the warranty work. Have driven another 50k miles with no issue.
I have a 2010 Chevy Avalanche. One day it ran great the next tap tap tap really loud. Guess what same problem. It is currently in Alan Webb Chevrolet waiting for a new motor to come in for it at a price of 10 ,000.00. We had 3 shops check it out and all said the same thing. Don’t fix it, replace it. It is an ongoing problem and will keep happening and putting new part with old parts never a good idea. Mine is the 5.3, My husband got a email about the class action but it said there was only 4 people and only covers 2014 to 2021. So if anyone has anymore information of who to contact for help would be great.
I have a 2019 Camaro with a 6.2 LT4 and manual trans . Does it have that cylinder dropping system? It only has 20k on it now.
I got a lifter issue 7 bank cost to replace about 1K
9 hrs labour 90h
My father had a 2018 Denali with 6.2. Started running rough and they replaced one side of the lifters. Can you imagine tearing all that apart to change just one side! He loved the truck but I told him to get rid of it. Lucky for Gm we are brand loyal and he needed a tax write off, so he traded it for a 22 lmtd. I hope most people will go to other brands. We have about 50 Gm trucks in the family, the seats keep getting harder and more uncomfortable. But the price keeps going up!
I have a 2021 Silverado 8000 miles ,just got word last week my lifters are bad on one side of the bank. GM only wants to replace that one side of lifters. I’ve been a loyal GM person but it might be time for a change. Now that the dealer have the lifters back in they can’t get a head gasket.
Right about these damn hard as a rock seats in the new trucks! Have a 2020 LT Silverado, & a park bench is more comfortable! (Narrow & no foam, bolsters dig in your back GM if you’re reading this) Nothing like the plush comfy lazy boy type bucket in my ‘06 Dually with fold down armrests) Oh & I had lifter collapsing issue(s) on my 2015. I’m about fed up with GM trucks. “The cheapening of GM trucks, while they cost you a fortune”.
If you are all about comfortable seats you shouldn’t be driving a truck. Thats not what trucks are all about. Power torque and pulling is a truck. Their first job and what they are built for is construction.
GMs only goal is for the engines to make it to the warranty expiration. Then it’s your problem. The only way GM learns is by the law suit or lemon law. Lemon law path is highly recommended.
How would you feel if it was an aircraft wing ? A wing that might fall off but ya know “most” won’t . Build it right OR fix it right ! Can the solution get any clearer ?
I really do hate to say this but… You and your family may be part of the problem . You acknowledge they are getting worse and you keep upgrading to worse. Time to break the vicious cycle maybe ?
How to get in class action lawsuit
Too old and dumb, he is 83 and I am almost 60. Gm dummies! We have tried fords in the 90’s but worse luck! Don’t get me wrong, can’t beat a Duramax!
Fords from the 90’s?? Sir, that was thirty years ago man! Theys a lil different today. Just respectfully say’n 🙂
It is great advice to any person who wants their money well spent to buy what from history you can feel quite certain to be a easily fixed and reliable vehicle. That is good advice.
As for what percentage of vehicles are affected if it’s your vehicle then it’s 100%. I had my 5.3 lifters go right after the warranty expired. The best fix is getting rid of the afm You will have to change the cam also but you will only have to do it once. I will never buy GM again. I hate to lose the North American car manufacturers but if you don’t respect your customers you can’t expect them to be loyal.
My 2007 5.3l flex fuel new body style dropped the number 4 cylinder lifter with 92,000 miles on odometer i changed my oil and filter religousley every 3000 to 4000 miles max $7000 dollar top end rebuild total delete of AFM DOD garbage gone i blame the federal gov for demands on auto companies to have a set limit of miles per gallon my engine had a distinct ticking noise with 12 miles on engine when i bought it dont blame lack of oil change for garbage lifters and treys i bet 80 percent of all these engines had the same fate i saw some clown on this web site said one to three percent of these vortec engines are experiencing this issue not even close almost all of them
I have a 2018 Silverado with a 6.2. The lifters failed on 1 side at about 15000 miles. It was fixed under warranty. About 3 weeks later it failed again and it was so bad Chevy put in a complete new engine at no cost to me. I now have 94000 miles but no more engine problems
Chevy needs to get their quality upgraded as they have more than an engine problem. I have already received 1 new truck because of their poor quality
This failure is very common. They’ve been sued before for the same problem. I had this failure in my 6.0L LS engine. Generally it would be an engine replacement, but I had a guy do a AFM delete with new GM cam and lifters. Still cost me over $2500.
Redesign the engine. Plus thus what happens when you have a idiot for a CEO.GM is having issues with the corvette transmission issues in most
I had this issue on a 2020 Denali. Lifter in cylinder 1 failed at 11k miles and the motor started to drink a little oil immediately after, and started having electrical issues. (Fail to start, dead battery, ignition lock etc). I traded it in. I’ve been a GM person for many years. I still have an SS sedan for now. This has changed my view and interest in GM going forward.
I have an 2007 Tahoe Ltz with 73,000 miles with a bad lifter estimates to fix $2,500 or even new motor
I have a 2004 lm7 with 305,000 MI I’ve had no problems whatsoever with the engine and I run the crap out of it.. friend of mine had a 2002 6 l HD it had 400,000 miles before he traded it in for a 2010 1500 with a 5.3 and he had to put two camshafts in it before 100,000 miles.. after he changed the second cam he then went over to dodge.. so, if you have an older lm7 keep it !
Always after GM. How about when Ford’s started catching fire, right in the driveway, with no one inside, and engine off! It was discovered that the ignition switch was the culprit, but ford refused to recall it saying there was no way the switch could do that. Finally they pinned ford down, and they did the recall. Problem was it would cost them 6$ per switch, and they had literally millions of cars involved. People don’t understand that a small repair can still mean millions of dollars, especially when you are the number one in sales. In the ’60s, at one point, every other car sold in America was a gm product. If their cars were junk they wouldn’t be able to do that. The sbc was the most reliable engine ever. The Mopar 440 with the hemi cam, 3 two bbl holleys and big compression was rated 385 hp and the little 327 from Chevy? 370 hp and over 100 lbs lighter+ 9000 redline
Ford basically invented the notion that it’s cheaper to let ’em burn and die than to fix the problem.
They actually did a cost basis analysis of the Pinto’s fuel tank placement prior to production and have calculated documentation proving that it’s financially cheaper to pay out the lawsuits and medical bills and funeral fees of customers than it would have been to install the simple protection around the back of the tank to prevent it from being a literal ticking time bomb if someone were to hit it from behind.
Just think about that.
Well at least GM Valve Lifters don’t Kill as many Americans as GM’s Ignitions…
Everyone knows GM is absolute crap, they just didn’t know they were designed to Kill you too.
Give me a break! Why are you even on this forum, if only to bash GM? Cry, cry, cry…boo who!
2018 Chevy Silverado 1500 wt. I had both banks replaced. All lifters. 30,000 miles later they went out again.. DO NOT REPLACE Factory parts.
The ignition don’t kill you, it’s stupid drivers that aren’t sure what they are doing that created an accident. Stop reading comments from cry baby’s that should take a driving lesson. The people who were hurt are those who don’t know enough to pull over and stay in the high speed lanes and allow the vehicle to die there. Thats a stupid comment based on stupid reading and listening to cry baby’s. Learn how to drive first and you’ll be fine.
I have a 2007 Chevy Z71 took to dealer has 104000 miles on it ran like a top one day lost power and lifters tapping is GMC going to fix Cause is AFM
So go by a Ford Ecoboost with 90% failure rate over the life of the engine. Turbo’s, water pump, valves ,cams etc. Then try a Chrysler with cams made if pot metal. Hyundai please there under investigation for crash test fraud….plus Kia as well. Every manufacturer has issues but let’s blast GM.
You don’t issue Safety Recalls for non-safety related problems which an engine valve lifter is.
As a former dealership service advisor there were a couple of times I questioned the reasoning for a particular recall. One was replacing a resistor (as I recall) that would burn out after years of use on the highest speed setting. Those that did not constantly run their fans on “High” seldom had this problem, which was inexpensive, didn’t take much time, and I thought ridiculous because how is your A/C or heater fan not working a safety issue. It was explained to me that if the fan did not work the windshield defroster would not work so people would/could drive around with fogged/iced up windshields and get into an accident. I replied that they could just use a rag or their gloved hand couldn’t they? The response was “some wont”.
People like this are why there are warnings on those cardboard windshield heat shields that, in big bold black letters say, “DO NOT DRIVE WITH THIS PRODUCT IN PLACE”; and why I have actually seen more than one individual ignoring that warning.
They also need to repair the 8 speed transmissions. Imagine being handed a letter by the dealership saying they know your transmision is broken but not to fix it.
Good morning folks I’m a owner of a 2019 Yukon Denali custom Black out edition with the 6.2L V8 and just put 40k miles on it and it’s been at the dealership since December 15 and the service representative said I need a new pushrod and lifters and I purchased the vehicle in July of this year and this happens thank God I have bumper to bumper coverage through GM. Unfortunately there’s a part shortage and I’m not getting it back until the parts arrive I’m not happy about this
I have a 6.0 2008 Silverado lifter collapsed. The design of the system has a high failure rate. Even changing oil every 3k miles wont prevent it. However when i repaired it i manipulated the vlom and had the computer re programmed to delete the 4 cylinder option. Its now v8 all the time. Best decisions ive made only lost about a mile per gallon and dont need to worry about it.
GM has issues and plenty of political appointed workers taking 6 hour breaks in a 8 hour shift. They don’t care about working or quality. Sometimes there are 1 or 2 people working though. Buy high-end after market lifters and make sure the roller pen is present, and leakdown. Do it yourself.
2001 gmc 5.3 lifters hammer every morning. I was told from a dealer. They were sold new with the noise.
You got a 21 year old truck? Are you being serious or not?
Just put $3,500 in my 2018 GMC Sierra 1500 to replace bad AFM lifters. Truck had 146K highway miles, immaculate in every other way. That large repair spooked me and I just sold it this week. My dealer has a guy in their shop and that’s virtually all he does is these replacements. Will gladly accept invite to the class action suit!
I have a 2015 Yukon Denali with the 6.2 and I disabled the AFM but apparently not soon enough. I have a lifter making noise and I know I will have to tear the engine down to fix it. But I’m not going to put GM junk back in it that’s for sure. I have been a loyal GM buyer for 45 years, not anymore. I have replaced more parts on this newer vehicle than all my other vehicles combined. I still have to replace the driver door wiring harness because they used the wrong wire. Once I have replaced and re-engineered everything with premium after market products I will have a good vehicle. I’m glad I quit working for GM when I did, I would hate to sully my reputation by being associated with their junk.
So now, consumers determine that a product recall is warranted. I disagree. Let the design engineers at GM make that call. That’s what they are learned and paid to do. Moreover, if the vehicle is beyond warranty time and/or mileage parameters; YOU pay! Some consumers expect unlimited/lifetime factory warranty coverage, regardless of what is implied or stated by the manufacturer. That’s utterly ludicrous! GM’s liability ends at some point in time…and should by all means, render them held harmless from these “frivolous” class action lawsuits.
There’s a reason I asked about the percentage of engines are actually a problem. My family have had a few afm engines and have never had issues. I asked my mechanic (who is a mopar guy) which truck I should buy. He said anything but an ecoboost. From his experience at his shop (which sees every make and model of truck) the one’s failing are from low quality oil or too infrequent services. I know it can’t be only operator neglect, but it makes me wonder about numbers particularly compared to ecoboost which are notorious for losing valvetrains.
I understand if it’s your truck its bad, but if the odds are worse with other brands, that isn’t better.
The issue is with the afm. If you drive easy ( no towing , no lead foot) then the afm kicks in often. Conversely if you are hard on the truck or use it for towing or heavy loads then the afm rarely kicks in and is less of a problem. The kick in the ass is that someone who babies their truck is much more likely to have a problem. Even when doing regular maintenance with factory authorized parts and oil the truck that is driven easy will suffer much more damage from the afm.
You are 100% right. I have a 2015 GMC Sierra Denali 6.2. Bought it 6 years ago in 2018 with 26,000 miles. I treated the truck like it was my wife. Oil changes every 3 thousand miles, never hauled anything, always put the 93 gas in from Shell or BP and only drove the truck around 300 miles a month if that. When my truck hit 53,326 i heard a ticking nose coming from Passenger side. Dealership told me I needed new lifters, push rod was bent but my cam was clean like brand new. so, i paid 4500 to fix. Gm said they couldnt help me. Exactly 5000 miles later the ticking came back. Once again it was the same side, passenger side. Lifters need replaced, push rod was bent again but this time they said my Cam had some wear on it. Another 4500 I paid but this time the Dealership Mech. Told me I should either put a new engine in it or sell it cause this problem is gonna keep happening. Well i don’t have 11,000 for new engine and I didnt really wanted to sell it because I had put around 17,000 in audio and custom lighting in it. so, it sat in my driveway with 62,109 miles on it wondering what i should do with it. Its been paid off. I’m afraid to drive it incase something happens to it again. So, I bought the AFM delete thinking it might help after reading many reviews about it. So, guess what… The driver side started making another nose, it started shuddering, power decreased. Back to Gm it went. Replaced the lifters and everything else that goes with it. I worked my azz off and saved every freaking penny to buy this truck to have nothing but problems. So, I was told the other day that I have a Lemon truck. I said a What Truck? He said Gm Dealership sold you a 43,999 Lemon truck
We have a 2006 Escalade that we’ve owned 10 years . It has 220,000 miles gets regular oil changes. Not using synthetic oil. It performs great and purrs like a kitten. No value problems ever.
buy a Lotto tix!!
Best!
How about the cadillac touch screen issues. Thousands are junk radios in cars no recalls.
Yup I have an 01 suburban 1500, with less than 110k miles on it. Needed a complete engine rebuild. Then it has started now with a lifter tapping that won’t go away. Replaced the lifters and no dice, I believe the culprit is the camshaft plate and gasket.
Don’t you have to remove the heads to replace the lifters in this style engine? If so that’s a big job for sure.
I own two GM vehicles a 2015 Tahoe LTZ and 2015 Silverado LTZ. Both vehicles within the last three days down and in the shop because of AFM, both vehicles maintained meticulously. Cylinder misfires, Tahoe in the number 7 cylinder and Silverado in number 6 cylinder. Stabilitrack light and flashing check engine light. Both vehicles just over 60K miles.
We still haven’t got paid for the Equinox for the oil consumption lawsuit. If we didn’t win that lawsuit, why do you think that anybody’s gonna win the lawsuit for the new Cadillac? The lemon law don’t apply for rich companies. Thank you Chevy for your wonderful piece of junk.
Thank god is right. I had this problem at 14,000 miles with my 2021 Siearra. The dealer made repairs to one set of lifters. TOLD me everything ok should be no further issues. I left after telling them I don’t believe it. Two weeks later vehicle back at dealer with lifter issues in other side.. Dealer replaced lifters.
To date after one year no further issues.
All owners of the 2021 Siearra should have the engines Diagnised for possible lifter problems. Don’t take this issue as just isolated.
Gregg here. Why buy any vehicle with engine problems. Stick with Toyota #1 car company on the world or f 150 #1truck in the world. That simple who wants headaches.
My 2021 Silverado is currently in getting the second set of Lifters replaced. 4000 miles ago, one set was replaced and now again! I have 40k on it and thank God for the extended warranty!
Buy a range device for the obd2 plug or have the engine tuned to delete afm. No more issues. You can also plug the oil hole in vlom located at the oil pressure sensor. Ive done them both lost a mile per gallon but got rid of the sluggish throttle which occurs when the truck is pushed from 4 back to 8 cylinder.
I have a 2006 envoy Denali with the 5.3 it is on the 2nd motor due to lifter failure of the displacement on demand failed , the envoy has undergone regular maintenance and oil changes every 3000 to 3500 miles or the oil still saying it has roughly 47 to 45% oil life still left but I changed the oil early due to this known issue and yet still had a lifter failure happen . Now I start it and allow it to run for about 10 to 15 mins to start to warm up and allow fluid to be pumped into the lifers and it still sounds god awful . This is just like the known issue with the 4l60e transmission going out on the sun’s and trucks .
My 2021 Gmc denlie
Lifters traveling back from Florida to
New York
How do I join a class-action lawsuit
Best fix for the 5.3 engine is to sell the truck and buy a Toyota. I just rolled over 328,000 miles on my 2008 tundra. It still has original spark plugs and no warranty claims. And yes, it was made in USA.
GM builds junk. The new POS Corvette has major transmission probkems. I was a loyal GM owner from 1973 to 1999. No more. Over priced piles of crap. But Ford and Chrysler no better. Hemis eat cams and lifters too. I believe the thin oil they recommend has something to do with it
I’m one of those owners in the litigation. 2017 Silverado Z71 with 5.3. Engine lost power and almost immediately sounded like rocks in a blender. This engine had ran like a top up until then. Synthetic oil used during oil changes. Truck towed to local Chevy dealership. Lifter failure caused major damage including broken valve spring. 75,000 miles for a truck that cost north of $52,000.00 GM Customer Service was horrible. They never communicated with me even though they said they would. They agreed to pay half of bill only. That left us with $5,200.00. out of pocket. The dealership said anything from 2014 to 2021 5.3 engines have has this same issue. They’ve replaced engines with as few as 8,000 miles on them. GM has a problem and they’ve known it for sometime but yet done nothing. When I did ask the GM Customer Service rep what I could have done differently to prevent this from happening, his answer was “nothing.” I have owned several GM vehicles over the years but this will be the last.
I was a GM person for many years but between killing of some of their killer rides like the Hto the SS and the G8, I switched to Dodge. I’m here to say after the tried and true old 305 and 350 small blocks went away so did the reliability. These newer engine designs have more problems and cost more to fix. Granted The new Hemi has the same cam and lifter issues . But GM has left it’s customers behind And only care about cheap made ugly vehicles
Just buy a plug in Range device. Problem solved.
I have a 2021 Chevy Silverado with a 5.3 engine. I had the passenger side lifters replaced at 6300 miles
My 21 suburban is in the shop as I type this. This was our first GM purchase and will be our last!!
I spoke with the dealer today and because there is over 8k miles (ours has 12k miles) GM will only fix the lifters that broke (one side).
From everything I’ve read and advice from my father-in-law who is mechanic, with these faulty lifters, if one side is bad the other side is too (same batch). Mine just happened to break at 12K miles vs. 8K or under. So, I guess GM is willing to risk my family’s safety over 4k miles. This is wrong and I could be in a situation where I am out of town on an interstate and not have the luxury of pulling over like I did yesterday. I’m not willing to take that risk.
Now with days before Christmas, I’m spending my time off from work trying to figure out what to do regarding buying a new car for the safety of my family!! I’m not going to chance this happening again while I’m driving and GM shouldn’t be willing to chance it either!!
I have a 2015 GMC sierra Denali pkg with the 6.2. This truck has been the most comfortable truck I’ve ever owned. In addition has been an absolute work horse and a tank for how rough and demanding I have been of it. I bought this truck new and was my first GM vehicle as my mother worked 30 years and retired from Ford I’ve always had Ford. I sit at around 95k miles and it run strong as can be with extra demand as well I’ve got a Diablo trinity EX tuner, BBK shorty headers and about 2 feet of pipe beyond the headers and that it for my exhaust (no Catalytic converters so engine light is on as result), 24″ wheels with 305/35/24 tires. I as well am very heavy heavy footed and many and frequent occasions have the truck going 150+mph. Only issue I ever had was the first time I did 158mph in the truck the next day under normal driving blew cylinder 7 intake valve spring also causing a hole to blowout into intake manifold from an open valve during combustion stroke of course. I repaired and replaced myself the valve spring and intake manifold with original parts from gm dealer and that was 40k miles ago and haven’t had an issue since.
We had problems long ago with this it was a 1974 big block 454 4 barrel Chevrolet truck
Buy a toyota, problem solved.
They’ve had issues since the 2007-14 suburbans/Tahoe with DoD/AFM, even telling owners to have oil changes every few hundred miles. I’ve had 2 2007 Suburbans(one for work) and a 2014 Burban. Looking at a 2015-2020 had having to look if the lifters on both sides were done is something I search for, apart from all the other recalls and TSBs.
My 09 avalanche has the 5.3 with over 310k. Runs perfect. Change oil every 5k to 7k. Use straight synthetic. No issues.
Doesn’t mater what vehicle or engine if you abuse it and don’t service it properly they will fail.
Have they fixed the problem on new 22’s?
Ps if you can get one
Based on my experience, This isn’t a new problem.
I’ve had afm/dod lifter issues back to our 2014 & 2015 4.3, 4.8 & 5.3 fleet maintained silverados. My experience w/our 2008-2013 ‘X” family, ZERO failures. For our 14-16 fleet, I think I’m up to 4 “H” family failures this point, ALL afm/dod related. That’s 4 of probably 36 14-16 models.
I was willing to deal with the occasional transmission failure, but I won’t tolerate engine failures related to one hard part failure. These vehicles were all fleet maintained, maintenance tracked with a targeted oil change interval of 5k. Not every change was completed at 5k, but they were not done one the system generated interval either.
In my opinion, this is a long standing issue, the general didn’t take care of the customer, nor correct the issue in a reasonable timeframe.
too high for me. I’m buying blue ovals for the majority of my fleet vehicles now.
I have a 08 Tahoe, on one 300 mile trip it used 3.5 quarts of oil. Lost 20 lbs pressure but saved it with Ranger device that deactivated the AFM feature. Most users experience this after the 1st 100k. Of course Gm offers no solution at any cost. My previous vehicle was a Dodge that they failed to warranty defective rear diff. I sold if for Chevy. Now I guess I will join my wife and go to Ford. They do standby there products.
Everyone saying bad GM bad GM you do know Dodge & Ford have the exact same problem right? They do nothing about it either. Exactly why I won’t buy anything newer than an 07. I just make my 2004 2500hd like new. You can delete the afm/dod. Who put & is still putting big pressure on these auto makers with crazy new regulations all the time though? OUR WORTHLESS GOVERNMENT! They’ve basically ruined owning a diesel now & are going after the hot rod/drag racing/performance industry now. Wake up ppl wouldn’t have these problems without the stupid regulations!
I absolutely agree….the minuscule economy gains has not come anywhere close to covering the addl upfront cost of the complexity, and ongoing costs of repairs and reduced reliability. This is a consequence the CAFE stds. My smog choked f350 CCSW gets 15.5-16.5 on the road. It’s a viscous circle. Addl fuel to clean the system, reduction in efficiency to run the restrictive system. I haven’t calculated how much addl pollution my truck creates in the name of cleaner exhaust, gut says it’s a push (on a properly maintained, good running truck), and the difference is more fuel, more upfront cost, higher maintenance costs down the road, more “pollution” due to more vehicles required/shorter overall service life of the vehicles.
@Andy, the dealership I used also sells Ram and Ford. The service manager said they not seen anything like this with Ram and Ford. I’m sure it does happen from time to time with Ram and Ford, but not anywhere at the rate it does with GM vehicles.
Which year models are we talking about, I have 2001 2500HD Silverado 4X4 with 6.0L and 2003 Suburban 1500 with 5.3L?
2008 suburban replaced the motor at 150k lifter issues not happy
Well … I partially agree with you. Big brother mandates fuel economy, the manufacturers look for quick and easy solutions. If we exercised our lemon laws a bit more the cost alone “might” cause the general (and others) to look for solutions instead of bandaids.
Maybe the solutions imposed by the government would add $20K to the car? Do you not consider there may not be a good solution to a crappy mandate?
Manufacturers do have to make money.
If you get a cancer diagnosis is there always a solution? Grow up and start thinking.
I have a 2021 Chevy Rst with the 5.3. It has 11,323 kms on it. It has been into the shop about 12 times in 6 months and I got it back last week and the tech tells me my lifters are going in it.. It’s a brand new truck. The warranty will only cover 1 more engine rebuild, so I am told. And I got the full extended warranty. And I have had two oil changes already. This is the pig pen and the should be cleaning it.
Although they will NEVER tell you this, the warranty begins again at new on the item replaced when replaced. But unfortunately you will have to fight for it. Too bad though, the one saying of my dad’s was If it’s worth doing it’s worth doing right. Too bad the General never met him. His other fav was If you’d just shut up no one would know how stupid you are. I’m sure that one could be used for some of coming comments. PS It may be time to sell.
Purchased 2021 GMC Siearra 1500, V8 Jan 2, with 3 miles on engine. At 14,00 right side lifters went out. Dealer replaced same assured me no further problems. I asked dealer to replace both sides they refused. Two weeks later left side went out. Vehicle towed to dealer they replaced left side. Now have 39 00 miles on vehicle no problems so far. I have talked to several owners of the same vehicle about my problem. Each owner was unaware that there was an engine problem. Most if them had less than 13,000 miles on their trucks. I advised them to contact GM or the dealer they purchased the truck from.
The problem with lifters has been on going. I have a small block in my 2011 Avalanche. It had the same issue. I had to replace the complete motor. Engineers try to come up with cheaper and cheaper alternatives, while spending more and more time and money on style and options to entice you into buying the latest and greatest. Remember, if you have made a vehicle for over 100 yrs, you should know how to build them. It shouldn’t be new territory. If young engineers are able to build differently, due mainly to cost, it should be tested on something other than me. Companies are only sued if they don’t agree with the customer and do not take care of you upfront. That you should always remember. As a business, you always take care of your customer and offer the best products. If not , you are subject to failure and bad press. After over 100 yrs of professionalism we should expect better treatment and products.
Correct. Replaced my 09 Tahoe engine. Only had 85k miles. Very well maintained. $6k later…
So sounds like I need to spring for an extended warranty. I have a 2019 Sierra 1500 AT4 with the 6.2L in it. Its got 36000 on it but I wanted to keep it and try and get as many miles out of it as possible. BTW my seats are actually pretty comfortable, they were stiff when I bought it but they seemed to have “broken in”.
I bought a 21′ Trail Boss and it dropped lifters and bent pushrods twice in the first 14k miles. Traded it in on a 2500HD with the L8T 6.6 gas engine since it doesn’t have dynamic fuel management.
Have any of you seen how and where these engines are built? I have a 2020 Silverado my buddy that builds aftermarket engines told me to add a oil catch can to my truck ASAP. I’m now at 53,000 miles and no problem. Also my truck is the 5.3 built end of September. All I’m saying is so far it’s worked me for and others that he has told. Maybe GM should add these at no cost to you. Just my opinion
Buy America ? If it were only made in America . The companies out sourced many components , only to say built in America . Meaning mostly assembled here . The catch phrase really is Bye America.
Almost sounds like you’d be better off paying for all of it. Take it somewhere else and put in parts you can count on.
Hyd lifter always were the part of an engine that had the tightest clearance BY FAR. Funny how up until 2010 there were not problems with both the GM LS engines and late model hemis. Then boom the bottom falls out.
I wonder are they still MADE IN THE USA like they once were. ??
Or have they went to the lowest bidder supplier??
I think you give them far too much credit. I’m confident they don’t give a rat’s _ _ _ . The truck sold, someone bought it. That’s where the caring stopped. We’ve got to find a way of tying their big bonus’s to customer satisfaction . Maybe then , they would also have incentive to provide the quality that was once there.
Man some of y’all are REALLY crying about the lifter issue. AFM and DoD sucked bad, but know of plenty that went along problem free for over 200k. Here’s the secret, Check your oil, service it when it requires it and most importantly USE AN AC DELCO FILTER! Don’t be a cheapskate! Fram filters and the cheap ones the used at oil change places are GARBAGE. They are cheap for a reason. Regular service is also a must because due to the small oiling ports on the lifters and the screen on the cam phaser sludge builds up and restricts oil flow. Any time I’ve replaced the lifters, the owner was over well over their oil change mileage and date, and low on oil. I’ve owned several GMs with the GEN3 V8, and never had anything but a little piston slap on a cold start up. Yes they use about a quart every 1k, the owners manual also specifically says they do and that it’s operating as designed. I’ve also changed the lifters on hundreds of them on every year, removing the head on a GEN3 V8 is so easy, I can usually have one off in about 20 mins and back on within an hour if I have all the parts right there. Those engines are so simply designed, I have even changed my cam on my hour lunch break. My 2004 GTO had 300k miles on it when I sold her and still had the original rotating assembly after two cam changes (performance,) sprayed with N2o, and redlined constantly. I beat that engine like it owed me money and never had one issue. My 2002 Tahoe with 220k runs like a champ, no ticks nothing, when I bought it there was a lifter tick, after the first oil change, I pulled the Jiffy Lube filter off and replaced it with an AC Delco, the ticking was gone.
Did everything just as you said. In fact, changed the oil the day before ours failed at 75K. Mobil 1 Syn used at every oil change with AC Delco filter at recommended interval. Our service manager says they’ve replaced engines with as few as 8,000 miles. I wouldn’t be surprised to see the 5.3 go away within the next year or two.
What year and what engine? The day before sounds VERY suspicious. Who changed it? I’m surprised the V8 made it this far, with all the tree huggers up in arms about them for most of my life. Most of us will see the end of the V8 engine within the next decade.
I have no doubt about your knowledge OR ability. But let’s face it… most of the buyers would be lost changing their own oil, pulling heads etc. is no where near their wheel house. For the most part ALL they know is it’s broken. That’s why they go to you. However for the actual tiny fuel savings one has to question why they tried to redesign the “mouse trap”. I’ve always believed in the K I S S theory. I find myself wondering if todays car or truck wasn’t a gas driven computer what would it cost to purchase and operate. So do we really need to redesign the “mouse trap” or the cheese ? In this case perhaps modern fuel would be better. Something we grow and refine instead of buying zillions of gallons of oil from other countries. Feed this to a 327 or 350 and Keep It Simple .
While I agree to a degree, the small fuel savings from the afm and dod systems is hardly a reason to implement such a system, but we need to remember that they were slapped with a requirement for a certain amount of MPGs by 20XX….I can’t remember the numbers. Ever since that was implemented, the automotive industry has done some pretty stupid stuff to keep up with that. I can say for certainty that the cars of today are garbage mechaniclly speaking compared to the early to mid 2000’s. E85 was a novel idea and all, and it’s great for your racecar (if you convert your car to it) plus it’s cheap, but we can only grow so much corn. There’s plenty of oil here in the USA, but we are not willing to tap into it anymore. The whole EV craze looks good to most, but what we don’t realize is that the EV is not a solution to any of the worlds problem. How will we maintain 330 million cars charging overnight on our power grid? What are we going to do with all the lithium ion batteries when they are no longer usable? What about the child labor and slave labor associated with the mining of said minerals? Since the implementation of the catalytic converter, the CO2 emissions is near zero. With all of today’s engine’s though they are hotter because the lean them out so much and cooking the oil up, you ever see how much the new cars burn oil? That what ruins most catalytic converters, and with how expensive some of them are, when they do go bad, most just punch the MFers out. Should we reinvent the wheel? No, we should always work towards improving upon what’s already been established as excellent. As for people not working on their own cars, many of these shops need to actually be considerate of their customers and their cars, yeah you’ll spend more on this oil change, but this is why. Most people want to hear that instead of the cheap route. It’s frustrating to see how many shops just want to make a quick buck and skimp on oil filter quality.
By 2026 all cars and truck will need to meet 56 mpg. The push is for electric has become so strong its gonna force out the gas engine. The design of reducing 8 cylinder to 4 by gm is about the only way to do it. Frankly its just a bad idea being forced on the public by a government. Amd pulling heads are really not that complicated its just nuts and bolts. Takes pictures and time and use your torque specs. For the vehicles that hasnt collapsed a lifter by a range device it will never go to 4 cylinder and the lifter wont collapse
While I’ve got to whole heartedly agree with the EV comment , the other side of that same issue is Gas is taxed and supposedly the revenue goes towards road repairs. If we stop buying gas and switch to Electric should we assume all levels of Gov. will be upping the tax on all electricity to claw back the lost revenue ? PS a lot of the so called oil reserves are actually oil, pumped back underground to store it for a “rainy” day. But the big question was and is Why did the General keep building these time delayed grenades Long after the problem was found?
Re n Re heads I can do. I do not need too. My newest is an 04 Avalanche with 5.3. I will NOT buy new from the General EVER again period. Persoanally I’d much have my old 72 back. Approaching a million miles a few engines and trans but never did it let me down. Any change I did to it was for me. But in a weak moment I sold it. Oh well. But the General is now ignoring problems to fill their corporate bonus pockets. And above all else… That IS the problem.
Their is also a trick to release the lifter its 50/50.it can be found online. Its fairly simple to try before you go through the process of removing heads
15+gcms are garbage from the magnetic ride failing every 45k to lifters and 800 dollar tailights. the gmc yukon has the most class action lawsuits this putting it at 7 cant wait to go back to lexus FU GMC
We all know an oil change is about the cheapest maintenance item that really does work. That said babying and frequent oil changes won’t make crap any better. It may keep it going longer though. Ya know until right after the warranty expires. Drive it like a truck. Work it like a truck. If not … well why’d you buy a truck in the 1st place ?
I have a 2021 High County with 6.2L I purchased brand new Dec of 2020. Do you think I most likely have one of these bad motors?
Thanks
Ask the dealer if they did the change up. If not… cross your fingers toes etc. and maybe push to have them correct the problem.
I have a 2010 Chevy Avalanche that is in Alan Webb Chevrolet getting a new motor because the lifters in the 5.3 L went bad and took out other parts with it. Had it in 3 different shops all said the same thing. Replace the whole motor. I have already had to replace the throttle body due to failure. Gm needs to man up and do something to help with these known problems. I’m not pretending to know anything about engines, I am disabled and this truck gets me back and forth to my dr. appts. The most it has been driven since we bought it was a trip to Colorado from Washington. I do need my truck be dependable for me. So if anyone has any good advice of who to contact please let me know.
I have a 2021 gmc sierra. At a little over 12,000 miles it stranded me three hours from home with lifter problems and GMs warranty would only take it to the closest dealership. Stayed there exactly a month. They fixed one bank. Now, at 20,000 miles here i am, stranded again. Luckily this time i was close to home. As soon as it gets out the shop this time i am headed straight to trade it in and will never own another gm product.
My 2013 chevy Silverado had lifter failure took out my cam I had to replace motor because gm refused to.
My 2010 is in the shop right now getting a new motor. I placed a call to GM and still waiting for them to call me back.
My 2010 Avalanche is in the shop right now getting a new motor. I placed a call to GM and still waiting for them to call me back.
Imagine… Even the “Asian” car companies offer better service then your dealer.
I have a 2021 high country with 6.2L and 12,800 miles. No issues yet and I don’t think they changed the lifters before the purchase. Im going through a oil consumption test bc it was low by 2 quarts since last oil change. It’s a shame bc I love the truck especially all the power. When I go back in to check the oil I’ll ask them about the lifters. But I’m thinking that I should just unload it while I can before and issues.
Sometimes gm vehicles use oil and some do not.that is not unusual. I have had gas and affiliate motors like Isuzu which always used 1 qt a week. That does not concern me nor should it concern you. The lifter issue is,asi have said in other entries, the ecm module. Moving the the engine from 4 to 8 cyl when it’s needed. That module should be changed to riding on 8 cyl full time. Other than that, that truck will last a long time.
That’s just wrong. I’ve had 4 cyl. 6 cyl. and 8cyl. engines Asian and North American made with 100 thou plus miles that did Not burn that much oil. Hell I even had a Lada that I bought as a winter beater that used less oil. And yes it Was a S..t box. It’s a shame to think, they’ve gone that far backwards.
Lots o luck. Hope you are successful. But the General isn’t exactly know for generosity.
No argument here. But if they need that DEF krap added it’s not as “fun” in my mind. Urea and water injected into the engine yumm.
This is an article I found on Auto Blog.:
Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed. So the lifter problem is due to the AFM/DFM correct? So if it is deactivated you won’t have a problem? Or is it do to poor lifter design?
Dm, After 20 hrs. reading and research, this is the exact same question I have been asking myself. Instead of griping and b1tching about it, is there ANYTHiNG we can do cohesively to reduce the cost and inconvenience of those who have yet to have this failure?
I certainly do sympathize with everyone who have experienced this totally unethical and irresponsible action by GM to correct a known serious quality problem. But we know it’s not only par for the course for GM to just write it off; but for other giant corporations who are deemed “Too Big to Fail”. (Ex. B.O.A.)
But, back to the question: Does deactivation or disabling of the AFM or in our case DFM (via a module) eliminate or even deter the inferior lifters from failing? If the lifters are of poor quality and or design, this may not help, despite what I’ve seen posted that it does.
And how much is fuel efficiency affected by disabling. Most say that it is only 1 MPG less. I see this could be much more depending on where and how you drive.
Certainly there are professional out there to answer these questions. I don’t think we should just roll over on this yet. I know I’m not. The Class Action is just the beginning, and if we make enough noise perhaps we will be heard!
However if what you are driving wasn’t a piece of crap, it likely would not have died a premature death. I flush crap. It’d rather not buy it.
Where do I start? Middle of December I got the dreaded lifter knock engine lights, etc. my 2021 Trail Boss with 12,000 miles had to be towed to the dealership. Here’s the best part -I’m 1,100 miles from home. I am expecting the truck will be repaired so I can get home before Xmas. The day before Xmas I get a call saying they can’t get a head gasket. Unfortunately my rental car didn’t have snow tires to get through the two mountain passes and all flights were full and hundreds canceled during this time. I spent Xmas 1,100 miles away from my family. Thanks GM
My truck was returned the following week and needless to say I was a little worried about driving the 1,100 miles since GM would only fix one bank of lifters. Well as luck would have it I made it 200 miles and the other bank of lifters went out. The truck is in the shop again with several other new trucks waiting for parts again. It will have been in the shop over a month total dealing with this. I’m still concerned about getting it home. This is a complete embarrassment on GM
I feel bad for everyone going through this debacle with these new vehicles.
Just makes you feel warm and bubbly all over doesn’t it ? The exec’s at the General get the bonus’s and you get the shaft. Now “rush” out and buy another. After all those poor folk in their ivory tower depend on you for their next vacation . I said never new GM again in 1986 and have been true to my word so far.
I have an 04 Avalanche that I inherited. But the Last new product from the General I purchased was a 86 Chevy Wrangler. I’ve owned Chevs since, but Always used. I would rather someone else paid the depreciation and went through “the growing pains”. Does that answer your questions? But I’d still rather have my 72 1/2 ton back. I even had a Lada Niva. Sure it was a s..t box but I knew that going in. Of my Fords, Nissans, Ladas, Toyotas, Ramblers, Dodges, Jeeps and VWs I found the General was by far the worst to deal with as far as after sales go. And as I stated some were crap , but I knew that going in. As far as I’m concerned the Gen. produced far too much New crap. C R A P should be flushed not purchased ! And now I await the trolls.
To the comment Gov may add 20,grand to the overall cost due to mandates. Imagine what could be saved simply in warranty repairs by just making it right the 1st time.
You think people can afford the extra amount then you must be rich or work for the government. You guys always have a solution. What dreamers.
I’m relatively certain you don’t have a clue of what you’re talking about. I’m certain none of the rest do either. You guys ? You Guys ? Why do you ramble on ? Yes Gov. rules may have increased the cost. But over spending on crap is just a bad idea. Give me safe reliable at a fair price and I AND others will beat a path to your showroom doors.
Interesting….I have a 2009 Tahoe LTZ that had 80k miles when the lifter failed and totaled my engine. I paid $6k to have an well maintained engine replaced with such low mileage. I was on the highway @ 65mph when I heard a bang. I lost 70% power and was fortunate enough to safely pull over and call for a tow. The tow truck driver immediately said, your engine is gone. How do I get on this lawsuit? 5.3 V8
My 2021 GMC Yukon Denali had a lifter / bent push rod failure at 9,000 miles. The dealer replaced only the one failed lifter and push road.
Aaah… Quality… I wonder if the top dogs at the Gen. had to fight this hard for quality (or bought cars) if it would even be an issue.
They also need an 8 speed trasmission recall. Imagine if the owner of a dealership or one of the hivher ups at GM were told your transmision is no good but thee is no warranty. I even have a letter from them stating that
Unfortunately the Top Brass don’t really buy new cars. Yes they drive them … but if the milk is free well you know the rest.
Hey Shane. Crap is crap period. And nobody wants to spend upwards of 100 grand for CRAP ! I flush crap I do NOT want to buy crap ! Nor do the others on this site. PS what is the General paying you to troll this site ?
Lol….well that’s fine then. Go to Ford or Ram and deal with their plethora of their own issues.
It’s funny how people take minority experiences and let that form their opinion about entire company/car.
Ford….they have axles and drivetrain components rusting out at 6 months. Or give Ram a go, with their TIPM issues and possibly have your airbag deploy randomly, or with their cracking exhaust manifolds.
Every manufacturer is going to have issues. Anyone who even remotely understands supply chain and manufacturing would know that. You cannot have a 100% success rate. It’s impossible. Extrapolating numbers, this issue affects about 0.05% to 0.1% of trucks produced by GM.
The point is that sometimes you get unlucky….get the warranty service and move on.
I have no affiliation with GM lol….just someone who uses their common sense and doesn’t flame online without using my brain first.
I use good mechanics and they tell me that all brands are crap. It just depends on what you want to fix… All brands have to be repaired. However, GM/Chevy has more than their share of MAJOR fails….. Fact. End of story. I bought my only Chevy knowing this…..
ALL brands can , will , and do produce crap. Absolutely. The problem is when you work your ass off to purchase one of these and time after time they fail. The older ones just did Not break down as often. They also did Not get the same fuel mileage as they can today. But they cost 1/10th of what they cost today. We do Not work our collective ass’s off to be told your engine is F..ked. And best of all it will be ready in a week or a month. Oh and by the way , we’ve only been ok’ed to fix half the engine. Plus they knew the problem existed but rather than correct it, chose to let the buying public find out 1st hand which ones were the bad ones. That IS the problem. We have become their unpaid Q.C. division.
Yep all true. IMO then if you want best reliability and engineering you’re going to have to buy Lexus/Toyota, then Honda, then Ford…. Not any GM.. And especially not any Dodge/Chrysler, Suzuki, or Mitsubishi
My Camaro SS has a lot of problems including the lifter problems…. Rear end is crap. Thermostat gauge stops working randomly. Radio is crap…. Road noise is the worst of any vehicle I have ever owned and I am 62 years old.
It’s a shame But I do not doubt a single word of it !
WOW . Make sure they update your warranty after all that work. They may complain , but ask them why not , you don’t stand behind your work ?
The lifters in my 2021 Denali failed as I was driving my children home from school. The dealer said the springs in the lifting mechanism were defective and they were replacing all of them. 3 weeks later I was told the engine was fixed and good to go. A week after we got the Denali back, we took our kids on a trip. The engine seized while we were driving on a desolate back road. It shifted into neutral on it’s on, wouldnt shift out of neutral back to drive. Display said conditions weren’t favorable to shift. It shifted to park and then wouldn’t shift back. We turned it off and it wouldn’t restart. It took 3 hours to get a tow to our location. It’s been at the dealership there (over 3 hours from our house) for 10 days. We just received word they have to completely replace the engine and we’re waiting for GM to approve it. It has 17,000 miles on it and we’ve had it one year this week.
On the 30th day, Lemon Law that beast.
Please follow-up with what they do for you no matter what happens. I just received my 2020 Sierra back a little over a week ago after getting all new lifters and camshaft hoping for the best. Was told by others to install an “active fuel management” disabling device but haven’t found one yet that works with the 10 speed transmission.
When you have the new motor put in, buy an item fom Amazon called,RANGE. It plugs in under the dash where your computer module is and switches it to full time 8 cyl and that problem will never return. It’s about$200.00. It’s well worth it. I just bought it. The alternative is same thing that plugs in under the hood thats about $1000.00. The 200.00 item does the exact same thing. I have 2 gms and I used both. They are no different from each other. 200.00 is a cheap alternative and you will get many many miles out of your truck.
They don’t make the Range for a 10 speed trany yet
How will you know if the new engine won’t have the same problems. I have them replacing an engine on my surburban now.
I can’t find where to enter the class action lawsuit. I have a 2021 6.2l silverado trail boss that had a lifter collapse at 3000 miles and bent a rod. Along with several other issues such as bolts free in the frame bouncing around as well as the headliner. The exhaust bolts were left untightened, the brake caliper was defective at 3000 miles as well as several other issues. I’m trying to figure out where to join on this class action lawsuit. I sold my 2016 corvette at a 13k loss due to the same issue as my truck. Ever since the lifters were replaced the truck drives funny, consumes more gas and doesn’t feel right at all. Shakes at certain speeds.
I have a 2019 chevy 1500 HD WITH THE 6.2 AND ITS DOING FINE!
I have a 2016 Silverado and the lifters just went bad damaging the cam. Going to cost me $5500. Naturally, I’m out of warranty so I’m out the cash too.
Even with problems, I still like to drive my Camaro 1SS with stick shift. I have a mechanic shop in my town and they are very good mechanics. They work on everything. In a conversation with one of the mechanics he told me “They’re all crap (referring to all makes of cars) it just depends on what you want to fix”.
2019 gm Yukon xl (POS) engine popped at 55,700 kms. They spent 6 k jerry rigging pieces back together, $100,000 junk, will never buy gm again!
I have a question. Do to the lifters going they are replacing the engine in my 2017 surburban that has thevAFM system. How can I be sure this won’t happen again. Has gmc Chevy rectified the problem or are they putting the same type engine back in that still has the same problems ?
how do i join in on class action suit
I still don’t know -how do i join in on class action suit for lifters?
Again I will say, if the motor is replaced,you must add the module to stop the vehicle from going from 4cyl to 8 cyl. This is the reason for you problems. It won’t go away with a simple replacement motor
OR There is another solution. Stop buying new from the General ! Buy a Ford or Dodge or Toyota OR a used one from from the General. If we all stop buying new from the General … They (the top exec.s) will notice. Once their excuses for paying themselves top bonus’s, once the golden eggs run out, things Will change .
My vehicle got new cam and lifters but looking at the Range to deactivate the AFM it says that it doesn’t work with the 10 speed transmission. I emailed the manufacturer to see if they have an updated one but no response
Lifter failure is common with this vehicle. I recommend letting the dealer repair it. Make sure both sides are replaced. If they refuse dump the vehicle. If the dealer takes it back will be in a trade or buy back but not what you paid. They will make repairs under GM Warranty and resale the vehicle at a good profit.
I experienced the same problem twice with my 21 GMC. At. 14,000. No problems now after repairs 59,000 now.
Good luck.
On A Positive Note…
Between me and my 2 business partners we have bought 8 Denalis trucks and a Sierra from the same dealer since 2015. I bought 2 in 2019, the lifters failed on one at 50K miles and was fixed under warranty, my other one with 80k miles failed a week ago.$10k estimate repair. The trade in value was $42k less the repair sooo maybe $32k if I just traded it on a new truck. The dealer sympathized with my story and gave me all in with discounts $51k trade in on my broke truck for a 2022 Denali which I bought at sticker. I then proceeded to buy the 4yr/100k extended warranty for $2500. The failures and repairs are disheartening but we do love the trucks. Kudos to the dealer for stepping up and making it right.

I sympathize with you sir on both issues. First for the lifter failures and secondly for even thinking that a Chevrolet dealer would ever feel any sympathy for a customer and “cut you a deal”.
I had my afm lifters go on my 2015 Silverado a year ago and had to pay an arm and a leg to replace the engine which was cheaper than to repair it. How could I get in on this law suit to get some of my money back.
I have a 2007 Chevy Z71 truck was running like a top 104000 miles than one day up and started tapping parked truck come find out it was AFM caused problem does anyone know if GM will fix no charge or are they going to leave us out of this suit to fix it
No warranty = you pay. Can’t argue that one.
Sorry to say I think you’re on your own. Count yourself lucky it lasted 15 years. We once bought the Generals product because they ran and ran well. If you’re otherwise happy with the truck find a good rebuilder and get a better engine. Then remember what they cost you before you buy another .
I had my AFM turned off with a turner since new in 2014 and my Cylinder 7 lifters just started to fail at 55k miles and I have a friend who disabled their AFM but his lifters failed at 100k miles but his also bent pushrod and damaged the cam.
I had lifter failure at 56,000 miles. Which caused the engine to go while I was 1300 miles from home GM replaced the engine with a new one, which took 3 months for the dealer to get. Flew back to get my surburban. Had less than 15 miles on it less than an hr from the time I picked it up and the lifters failed again on a brand new engine. Dealer replaced the right 4 lifters. I am at a loss on what to think. I was assured that gm rectified the lifter issues related to the AFM system with the new engine. Obviously they haven’t.
No I shouldn’t be on my own when it comes to fixing my truck they bluntly knew about problem and bandage fixed it for people once warranty ran out tell customers they have to pay to fix it that’s bull especially they were in wrong for years they’re covering 14 to 17 they’re out of warranty to so don’t say I should eat cost I kept my oil and everything up to par could of got 300000 or more miles out of it. but not now for a company to rip people Judge should rule for us all that got ripped off by GM
GMC 1500 crew cab Elevation 4200 miles. Lifters failed and cam shaft. 3 weeks in shop with no support and $35 a day they offer in rental car. Still waiting to here. Called customer GMC service and they where as cold as could be. Should I dump it when I get it back?
Lemon law …. GM only responds to financial hits.
Have a 2021 Gmc Sierra and the left side had a bad lifter at 10k miles and Garlyn Shelton GMC in Temple Texas fixed it on a Saturday, we were 4 hours from home at my daughters. They said since over 8k miles would only replace that side but service guy said almost all fail before 15k if going to. At 13.8k the right side has a bad lifter and has been in shop at Mitchell GMC in San Angelo Texas for 3 weeks waiting on a “backordered” part. What a bunch of bs! You know you have a problem but don’t have the parts to fix in stock?! Of course they blamed the pandemic, I have had it with GM.
Mine failed at 49,000 they said most failed by 13,000. Replaced all of them and the camshaft…it doesn’t seem to get as good of gas mileage after the fix, and maybe even what I would call a stutter as the cylinders kick back in???
Join the CA Lawsuit. I’m going to as soon as mine fails.

Jimmy, I am nearly 80 and I fully sympathize with you. I have a 2021 Silverado with the 5.3L with only 5,000 miles that I am preparing to sell before something similar happens. I’ve done extensive research on this GM design fault since I became aware of it about 6 months ago. There are several different engine problems and failures ALL related to this inferior design and in my case faulty parts (lifters) and faulty (factory) installation. Even under warranty I refuse to wait until this failure happens and be without a vehicle for perhaps weeks to get a shoddy half ass repaired vehicle back to fail again.
In your case I think you need to take the “squeaky wheel” approach. You said in your first post that you have several warranties, but with only 25,000 miles, you should be covered with only the the 50,000 drive train warranty. If you are indeed warranted you may need to escalate your problem higher up the GM organization to get results. Find out from your dealer who you should contact next, obtain written documentation where possible of the problem and the solution. Talk to anyone who has knowledge of how to resolve this issue. Being blown off by a comment like “IT CAN’T BE FIXED.” is not an acceptable answer!
IT CAN BE FIXED! IT’S JUST A MATTER OF WHO AND WHEN.
This is just my humble opinion. I hope it helps.
Call gm customer service to put in a customer complaint issue. Explain your situation and the dealership and people you spoke with their by name. Dealerships rely on perfect reviews or they have problems and someone will get in contact with you from gm and I’m sure later from dealership after gm calls them. Things may not come out the way you want but you will get some action. My engine went bad past warranty on a Yukon xl, lifter took out the cam. After no help from dealership except pay for a new motor I contacted gm explained my issue and long line of gm purchases. I was able to get new engine at half the original quoted price.
I have a 2019 Silverado. Lifters bad at 94k miles. They replaced only one side. Now at 96K miles transmission is bad. Need new transmission which cost $5300. This after paying $2800 for the lifters. Need help. No Lemon Law help past warranty.
Have extended warranty? That would help.
Mon sierra 2015 avec 116000 kilomette
Lifter probleme #7 il l’on changer 2 fois
Et eu un probleme de l’autre côté et on changer toutes controler a v4 ect… ca ma couter tres cher pour arranger je comprend pas que gm garantie se probleme car cest leur conseption qui est en cause
I just got my 2021 Silverado with less than 13k miles in for lifter issues. Had to cut trip short. Had to rent a car for two days on my own. Obtained list of standard parts to be replaced. Still waiting for work completion timeline.
make sure they replace ALL the lifters and the camshaft…..otherwise you will probably be back in for more repairs
Once again, if your vehicle is under warranty and out of service for more than 30 days, you’re nuts not to explore the lemon laws… state and or federal.
Pretty sad that so many people are clueless as to what a recall entails and the reaaon(s) they get done.
FYI it isn’t because something had a bunch of failures. Recalls are issued when there are legitimate safety concerns, not because a part has a known failure location.
You are correct, unfortunately. I have read so many of these posts concerning this failure and how so many expect GM to repair their vehicle when the vehicle is way out of warranty. I’ve got a Silverado with these bad lifters that could fail any day, but I’m not going to expect GM to fix it if it’s out of warranty when it does. we are look at it it’s my fault for believing GM and buying the vehicle in the first place. I do blame GM for the lousy way, they’re approaching this with their service bulletin, but again this GM just trying to manage damage control.
My 2017 Silverado 5.3 ate the lifters at less than 10,000 miles. Dealer would only replace one bank. Sold it and bought a 2022 ZR2 with a 6.2. Does anyone know if I can drive it in L9 to keep the DFM from enabling without hurting anything else?
GM won’t give me a straight answer.
having been victim to this GM Curse, I installed the Module into the OBD socket under dash that PREVENTS the computer from telling engine to going into 4Cyl mode. It works!! BUT…….while NO HARM seems to appear after 3 months now, and removal of module restores eng to 8/4 Mode immediately.
Sadly several other poor souls have done same and the lifters STILL fail eventually ( 10-60K miles) I’m bailing out before the lifters fail again AFTER the 2 year Warranty ends…… ( Jeep, Dodge??) damn shame GM.
And they never will, unfortunately. GM is like most doctors. They are afraid of answering questions in fear of them maybe being held accountable!
Buy a tuner I bought a range off amazon 344$ Canadian keeps it in V8 always works great. I had # 7 lifter go in mine changed the hole side 2K then misfire o #6 parked it until I got my range now runs great. You can also get it re tuned to cancel the switching to V4 which is about 300$ too.
yes, they are still using the defective lifters
My 2008 Tahoe has defective lifters so when it fails I have stop using the vehicle for 45-60 minutes before I can use it again. This happens usually on my 115 mile run to the lake house. What a PIA to find a safe place to pull over for an hour in East Dallas, life risking requirement to have this Chevy product. I spent the 200$ for the range device utility still fails on hour long runs. 55,000$ vehicle with a known defective that GM refuses to address. Last GM product for me my children and 5 other family members family’s, (approx 22 drivers) will never purchase another GM product.
Yeah, it’s totally messed up with the public has to find ways to fix a problem that GM is responsible for in the first place. even worse is the people that buy those modules or $200 or more are perfectly fine with doing that, Even though they don’t work. I wonder if the GM execs have stock in the range module manufacturers.
Its not the lifter that is defective its the design. This problem been around since active fuel management has been installed in gm motors. They use oil which gets dirty through the drive cycle to control the locking and unlocking of the lifter. Over time a build up occurs around the locking pin and it fails. My 08 busted up the vlom blocked the oil passage installed a range device to kill the ecm from trying to trigger the drop to 4 cylinder. All to get 2 less miles per gallon. Anyone buying a new gm with afm should pull their ecm send it off and get the afm deleted and put it back you will be much happier
Just deleting it in the ECM won’t stop it from failing. If it did mine should not have failed at 74,400 miles. I was just 2400 miles out of the extra warranty l purchased for my 2015 GMC SIERRA Z71. GM and the dealership would not help with any of it. I had it towed to an independent mechanic and got it fixed and it was unfortunately done with the same parts due to the availability of parts issue everyone was having. If mine fails again l will be putting a delete kit in mine. Turning it off in the ECM or buying a Range Control Module just buys you a little time. Because of the design of the parts it is going to fail. It’s not an if, but when is it going to fail. If it fails under warranty the dealership and GM are only going to fix it at most a couple of times . After that it’s up to you to get it fixed.
Wallace, You are absolutely correct! I wish there were some way to inform ALL CURRENT OWNERS with DFM or POTENTIAL OWNERS of vehicles with DFM of this fact.
GM does not care one rat’s ass about taking any accountability for this issue. GM makes $$ from Extended Warranties and after being repaired your vehicle is worth less on trade and the companies that sell the modules DO NOT warranty against failure either!
I have a “ticking time bomb” (2021 Silverado RST with 7500 miles)that I hope I can find another suitable truck before it happens to me and all I can do is get on this blog and ventilate!
2018 5.3 . At 142,000 I had 4 lifters collapse. Replaced with OEM parts that took 3 weeks to come from Tennessee to Florida. Now I’m at 181,000 and both lifters on cylinder one collapse. Better go but you a range AFM delete module to save your truck. First round was $3,300 to replace both sides. Now have to shell out $1800. To do one side and hope for the best.
Those modules do nothing to prevent lifter failure. The problem is with the dfm/ lifter design itself and We will continue until GM does something about it. My opinion buying a module is throwing good money after bad.
Yes, the problem is with the lifters, they collapse when the cylinder is being deleted and then re-pump up when the cylinder re-energizes, when they fail they stay collapsed thats where even bent pushrods happen using the Range module to turn the system off makes it so the lifter never collapses period….problem solved. My lifters failed and GM replaced all of them and the camshaft, they said the lifters they installed were a different part number than the original…a redesign possibly? After I could feel what I would call a stutter when the cylinders kick back in, installed the Range and no more stutter
Yes, problem solved for now because they havn’t failed again yet.
Wonder if the GM execs have invested in the module manufacturers also.
So, you want the person fixing it to take on financial hardship so you can get a discount? They have to get paid for the work. Or you can spend all the time learning this stuff and all the money on needed tools and do it yourself. Maybe then you’ll understand. It’s not “about the money”. It’s about getting your truck fixed. If you can’t afford the upkeep, you can’t afford the vehicle. Next time, don’t buy a vehicle you can’t afford.
Any vehicle with the AFM should get a DOD delete because you will eventually have this problem. You can turn it off for a quick fix but you still need to get a delete kit because the lifters will eventually fail. If you hear a ticking sound you need to park it. I wouldn’t have the dealer do this for you. I’m not even sure they can or will do it for you. Just Google DOD delete kit for your vehicle and there are plenty of reputable companies that sell the kits. You may want to call them to make sure you getting the correct parts. The one I went with was super helpful over the phone. (BTR) Go to a local shop that specializes in LS engines to have the kit installed. Good luck everyone!
Get yourself a DOD delete kit and have it installed by a reputable shop (not the dealer) or get rid of the vehicle. That is the only “fix” for the issue. That’s coming from a family owning 2 Pontiac G8s, 1 Chevy SS, 1 Chevy Tahoe, 2 Chevy Camaros and 2 Chevy Caprice PPVs. You MUST get rid of the active fuel management system. Turning it off is only a temporary fix.
The DOD delete module won’t help and neither will reprogramming the ECM. I know because I had mine reprogrammed and it still broke. It’s the way the engine is designed that it is guaranteed to break. Number 7 lifter collapsed and the push rod bent. The dealership had it eight days and didn’t know what was wrong with it. I had it towed to a mechanic that works on this problem all the time. Took him an hour and a half to figure out what was going on. With what l had to pay the dealership, towing, and my mechanic to fix it, it cost me $3100. And mine went 2400 miles out of warranty and no help from GM.
Great choice in vehicles
I have a 2021 chevy silverado with 5.3 currently in shop with lifter failure caused damage to cam shaft. Over 7,000$ to repair. That I don’t have. So it sitting. 108, 000 miles. I baby this truck. All maintenance on time and this crap. And no help from chevy.
How do you become part of this lawsuit??
I have a 2017 Escalade, cylinder #4 has no fire.
I was told I needed a new engine or it could possibly be a broken lifter spring??
It has 95, plus thousand miles in it.
Find a new automotive tech and pay them to properly diagnose the issue. An eninge is on the extreme end, I have owned several variants of the gen 3 V8s, many with over 200k and never had to replace an engine, even after lots of nitrous. Sounds like a bad lifter from, probably from not changing your oil. Your engine has DOD, it shuts down 4 cylinders when the power isnt needed, bad design but mainly because of owner neglect such as not changing your oil, using cheap filters, or running low on oil.
Is there a recall on this engine??
has anyone had any luck getting some financial assistance from gmc for this? out of warranty of course and didn’t get the extended. second time this happened and now my cam shaft is broken too.
No. Now that Mary Barra has sold GM out to China don’t expect any help from them. Sad.
I got a Avalanche 2009, No 7 low compression had a tic tic in it but didn’t know about this lifter issue I got 410,000 km on it so lucky that way wonder if I just replace with lifters one side or replace both with regular lifters new cam. And delete the AFM system
I had both bank of my lifters go back in 2021
They went on trip back from Florida it want fun
100 miles from home! I’m still hesitate taking
Long trips recently my fuel module went
Love Gmc have many years but after this last event
It may be time to move on from the brand
My 2009 lifters collapsed with low miles. Please ad to this list
2019 Silverado Z71 4×4 5.3 DFM engine 79,000 miles. #1 cylinder misfire. Bad Lifters and Camshaft damaged. Dealer cost to repair $7800.00. GM customer service contacted, but they refuse to admit the Lifters are defective, and they refuse to provide any financial assistance for the repair. Based on all the internet and social media traffic, this is NOT an isolated incident, it is widespread problem that is affecting millions of vehicles. It is not a matter of if the Lifters will fail, but when they will fail. I will NEVER buy another GM product.
I am currently waiting on parts to do this a second time on my 2015 Silverado. First time cylinder 4 collapsed at 131,300 ish miles. This time its cylinder 7 at 136,108 miles. Cant afford their $3k bill each time. GM should have know this was a poor design.
