6.2L V-8 Lifter Failures

You may want to appeal that decision! My 2020 GMC 6.2L experienced a lifter failure at 8,200 miles – fully covered under the warranty. THis is a known problem to the service technicians…

mine had 130,000 with a lifter failure 2018 denali

2021 denali w 6.2L. about to run out of powertrain warranty. Have not had the lifter problem yet… but VERY concerned based on multiple dealership and forum reports. Technicians are being muffled on what they can say about it – had a few guys comment to me from multiple shops now and use the “off the record” before they commented about the stuff they are witnessing daily. I have been told by multiple dealers that it is not ‘if, but when’ for the lifter problem to happen. To be on the proactive side I priced the lifter and pushrod change at my dealership to preemptively address my concerns however the $12k price estimate had me reeling.

I change my oil right away to synthetic upon receipt of my new vehicle and there after religiously every 3000mi. Also installed a catch can which is surprising how much crud is captured (especially when it’s cold out as it also gathers condensation in those lower temps) Perhaps this has helped to sustain my truck – only time will tell. Will consider a 6.6 duramax or perhaps leave the brand that I’ve been so loyal for the past 20 year and go Toyota for improved longevity. GM has a very big problem on their hands & it’s not the lifters but permanent loss of clients.

21sierrablues, first no technician has been muffled about the lifters and anyone will tell you that is has been a on going problem however the new generation lifters seem to be a lot better than in the past. Just a heads up, your Denali can with synthetic oil and if you have your oil changed at a dealership you got synthetic oil.

Keenas1962, that is one of the dumbest reason to deny a warranty claim that I’ve ever heard. I’d be curious, was it the dealership or GM that denied the claim? Funny part is that I could drive back to my dealership and I’ll bet we have 10 or more trucks on the lot with tires that are larger than 4 inches bigger than stock.

I just dont get some service dept these day, I’d do everything I could to push this jobs through under warranty, lots parts and labor they are pushing out the door.
