NHTSA 6.2L Motor Failure Inquiry

[AXE]

This specifically states the bearing failure, not the lifter issues.

GM is potentially facing a large warranty issue as the National Highway Traffic Safety Administration (NHTSA) opened a preliminary investigation into engine fa...

Also this article has a link to another class action lawsuit for the bearings. Those of you with failures may want to sign up in case there's other compensation.

iT'S ABOUT FREAKING TIME!

My 23 only has 3600 mi on the clock and I am constantly looking over my shoulder whenever I drive. I have not had any issues with the truck "YET" But that could change each time I take it out. I do have the full warranty and extended warranty on the vehicle. I hope to soon have the hood wrapped (glare issue) and the truck de-badged and have it pin stripped with paint to high light the lines of the truck.

I posted a link to this in one of the many 6.2 failure threads earlier as well, it’s about time. I’ve said all along it’s ridiculous to give GM a pass on how bad these motors have gotten. Pure nonsense to “accept” we should have to consider this the new norm and go on.

It does not include model year 2025. Did GM make a change and not tell anybody?

Probably just finally got the parts flushed from the system and manufacturing adjusted.

Just start pulling oil samples and you'll know if the wear metals are too high. Nothing will prevent catastrophic failure, so it either happens or doesn't. Seems like fewer issues as the miles are now piling up in some of these rigs.

Yea, I have been watching the oil and been changing it just for added insurance. I am using Royal Purple 0-20 weight. I have had good results using it in my race car.

Oof. Instead of messing with GM and all the time we have to spend with our rigs in their shops, is there shop or something that we can take our rigs to or do ourselves (if you have the tools/expertise) to get upgraded bearings or all the other things that might fail? Crazy that GM is good with all this. If everyone left and went Ford, Ram, or Toyota that will hurt. No one wants to go that far though. lol

I'm not sure if we've gotten to the bottom of the problem? Is it bad bearings (main crank and rod), bad camshaft, or bad machining in the block. Could be a combination. They'll never tell us until the lawsuit proceeds.

YouTube is going nuts over this issue now. I've seen many videos posted today. TFL did one, but they kind of downplay the significance. Read the comments, there's so many 6.2L failures it's hard to believe.

After seeing these comments, Reddit, and the ones on this forum it seems more prevalent and now I see why it's 3 months waiting for a motor.

This is going to affect resale a lot going forward. Nobody will want one of these time bombs.

Hopefully GM is forced to warranty them for 5+ years and 100k miles.

I had the 5.3L in my 15 Silverado fail, because of the AFM and the lifters, about 5 years ago and the motor was replaced under warranty. Didn't take long to get the motor and the total job took about 3 weeks. It still sucked goin thru that situation back then. Surely don't wanna go thru it again with this 6.2L. Especially if it takes such a long time to get a motor these days.

Royal Purple is a very good oil ! Thats my go too oil for sure!
E.O.S. additive by AC Delco goes in every build!
I've seen as much as 5-8 HP on the Dyno by just changing from any other brand.

I got my 2007.5 as a demo with about 6k on the clock.

It failed due to lifters/AFM about 5 years later with close to 62k on the clock. The dealer didn't want to fix it, but I pressed the matter and threatened legal action.

I sure hope that doesn't happen again.
