How GM Dealers Handle Engine Valve Lifter Issues
Sponsored Links
A few days ago, we published a report highlighting the valve lifter issues some General Motors customers were experiencing in certain vehicles equipped with either its 5.3L V8 L84 gasoline engine or 6.2L V8 L87 gasoline engine. In light of this article, we’ve decided to provide some insight into how GM typically handles valve lifter issues on vehicles still covered under warranty.
If a customer brings their vehicle to a GM dealership and reports a valve lifter problem, the dealership will first determine whether or not the customer has experienced a previous valve lifter issue with this particular vehicle. If they have not and the vehicle has less than 8,000 miles on the odometer, the dealer will replace the lifters on both cylinder banks. If the vehicle has more than 8,000 miles, only one bank of lifters will be replaced.

If the customer has experienced prior valve lifter failures, dealers can choose one of three options: replace one bank of lifters and offer the customer a 60-month, 100,000-mile Powertrain Component Coverage Letter, replace the entire engine, or reach out to the District Manager of Aftersales for further guidance. The solutions are similar for a customer that has experienced valve lifter issues in the past and had one bank of lifters replaced. In this case, the dealer can replace one bank of lifters and offer a 60-month, 100,000-mile Powertrain Component Coverage Letter or reach out to the District Manager of Aftersales.
The aforementioned valve lifter problem affects 2019-and-later model-year Chevy Silverado 1500 and GMC Sierra 1500 pickups, as well as 2021 model-year full-size GM SUVs, including the Cadillac Escalade, Chevy Suburban, Chevy Tahoe, and GMC Yukon. More information on the issue is available in our dedicated report.
GM Authority intends to follow the valve lifter story closely and report on further updates as we receive them.

Well Dennis… You can deny the logical and the truth but it’s the science based facts that your feeble mind won’t grasp. Too bad. History tells us you are doomed. Doomed to continue making the wrong decisions over and over. Oh well just another doomed lackey.
So rather than bi*ch at each other, how about we focus on the issue of these lifters…
I have 21’ Denali, @ 8k miles pulling our travel trailer for a quick trip the left bank goes out. Bring it in to my local GM dealer, they have it for 7 weeks, I hook up to trailer again to deliver to some friends for a weekend and the right side goes out. Return to local GM dealer where they end up doing right side, wish they would have done that originally butttt NO, would never allow that to happen. I got the pickup back this time in about 2.5 weeks.
Now, cold starts in the morning is a pretty active “ticking” that I can’t pinpoint. Anyone else having continued issues??
Some say they have driven it until it “blew”. New engine, No problems (YET)
Not being at the factory we’re the components are made. Isn’t there a system of quality control? From the steel coming in to the plant. Then from construction to final product is QC completed? I know how it should function just not in this application? Anyone?
Should , would and DO seems to evade them. Plus after a few hundred “went” early on… They shoulda ,coulda ,woulda… But didn’t bother.
Does this lifter issue affect the 2022 models? I’m looking at the 2022 silverado with the 6.2L ecotec3 with DFM.
All their V-8 engines are going to have the lifter issue. Junk.
Good for you fireboots. Take no prisoners and never take the 1st No from the dealer.
Have a 2009 and a 2017. Had to replace the motor due to a oil issue. Didn’t know we’re the oil was going. The 2017 had a lifter go out. They had my truck in the shop a month already. Told me they would replace both banks. It’s now only one lifter being replace. I’m never buying a junk Chevy. Done with GM. They can’t take responsibility.
Had a broken lifter on my 2021 Silverado at 9300km. Dealer got it fix. A week later, I have notice a weird noise when the engine runs a few km especially on the highway and then stop to run idle. A month after back and forth discussion with my dealer to fix the noise, they came back to inform that they need to open up the engine head to replace the head gasket since the mechanic got it installes backwards. Basically 2K km later. Does this sounds normal? Am I entitled to be compansated with and extended warranty offered by the dealer? Should I request a new engine? Thanks
How many times for the same problem before it’s a lemon?
Dropped my 2020 GMC Sierra x31 truck off at local GMC dealership for an oil, lube and filter change…Everything was running perfectly
when I had dropped truck off … While driving away and before leaving lot, “Service Parking Brake “, “Service ECM” and engine/wrench light came on. Backed it up to drive through oil change to report to Service advisor. This is my first new truck and I’m soooooo frustrated with the “gremlins” that have popped up…it has less than 17,000 km
