General Motors V8 Engine Valve Lifter Lawsuit Claims Recall Is Needed

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 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.
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.
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!!!

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.
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.
That 5.3 LM7 doesn’t have lifter issues unless you fail to change your oil regularly.
I’m at 260,000 miles on mine and still going strong.
Yes they do lifters collapse and have gotten turned causing the cam to round off lobes. Ive seen it a bunch and its not cause of oil changes. The hydraulic lifters just go out.
Not on the early 2000s LS engines.
Take your Ignorance elsewhere.
The only issue on those engines is the rare castec heads or the valve dropping into the engine on the 5.7L ZO6 engine.
The LM7 doesn’t have lifter problems end of story.
Yes they do! I have a 2007 thank you and I change my oil religiously on time, and I had to have my lifters replaced.
my as well 2007 escalade just had lifters replaced
That is what I used to think until my 2021 GMC Denali crapped out at 9000 miles. Not only did it fail, but GM would only replace the failed lifters (drivers side) and the pushrod and valve spring that was damaged – would NOT replace the other side.
Never had a single warranty claim of any kind with any of the previous 6 (25+ years worth) GMC trucks that I owned (almost a million miles worth) …..until this biatch. I will never own another GMC and I will get rid of this one as soon as this pandemic related shortage is over. I DO NOT TRUST GM ANY MORE.
Exact same thing thig happened to my 2021 Denali. They are being instructed to replace all 16 now. I made a formal complaint and GMC offered to replace or buy back the Denali. still deciding what is the best option. I just feel that I am always at the losing end of it since they will take value from mileage and wear and tear. I wouldn’t have bought the vehicle if I was aware of the problem.
What’s amazing……is GM, rather than disabling the AFM……..puts the same defective crap into your engine. And it could happen again……..soon!
dump it!! It will happen again!!! Its the design…… Sell it back….. or one rainy nite in Trenton……
From a sad, loyal GM guy…..
I can empathize with your pain and frustration. And GM only replaced one side of the lifters? Terrible.
I just called a GMC dealer, asking if there’s a GM-approved way of disabling……..they said “NO” – wonderful! lol. Why wouldn’t they have a way to disable them? That’s a real head scratcher, considering what this issue costs GM, it’s customers, etc.
Get an AFM DISABLER on Ebay! $115. Just plugs into Port under dash. ( remove before Emmission/Inspection test) Does NOT altar Computer permanently!!! Simply remove and all returns.
NOT known if it definately resolves issue forever, but your sled will STAY in 8 Cyl mode ALL the time. I love mine. But Bye bye GM soon….
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.
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!
And yet you keep gullibly buying more GM products. Making you and your family a big enabler to GMs crap.
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 🙂
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.
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
