General Motors V8 Engine Valve Lifter Lawsuit Claims Recall Is Needed
Sponsored Links
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.

On A Positive Note…
. I bought2 Denalis for my business 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.
