NHTSA 6.2L Motor Failure Inquiry

[MNNJR69]

My sentiment is the VAST majority of people buying vehicles equipped with these motors aren’t on forums researching a “hack” to keep their v8 alive. I don’t believe GM published this in their owners manual either. You shouldn’t have to do all of this after 20’ish years of some variation of this problem…

Agree I've said it before and I'll say it again. We are blessed to have this platform to share all this information that would otherwise not circulate. I am extremely grateful for all of the active participants in this form and the information that has been shared. I definitely believe what I have learned here has helped to save this beautiful truck from catastrophe.

I am the type of person that wants to know everything I can possibly know about something I purchase, especially when spending $85k. I just wish I would have learned more before my purchase, so to have prepared myself better. I'm just coming up on 30k on mine and can't imagine what might have happened if I had not made the modifications and taken care the way I already have. I also believe that most manufacturers are deceptive in their maintenance schedules in that the intervals are not closer and can lead to other major issues. I believe they do it intentionally for the money, In a manner forcing most people to purchase again or pay dealerships for overpriced repairs and that's sad! On most items whatever the manufacturer recommends, I divide it in half and go by that schedule. That mindset has served me well and I absolutely love my truck.

I drove mine 30 miles today, never left L1-L3 and got 9.6 mpg. Drove it like I still had 12 months of warranty left and enjoyed listening to my Magnaflow exhaust over powering my weak ass Bose system blasting some Ozzy's Boneyard!

Love these cold starts now that it's cooler here in Vegas. They rumble the walls and turn heads in parking lots

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 think it's more common then most of us think it is. I was scared of my 1500. I took mine in for brake control problem and the guy sitting in the waiting room beside me got told he lifter failure on his. Was a 2019 1500 couple years ago. I was in several different GM groups and it just seemed like a lot of engine failures across the board. Youtubers always down play stuff because they depend on the good graces of the manufacturers for press vehicles and early access to information, ect.

I'm curious to see how many new failures get reported now with all the press. I'm sure lots never got reported. It's ridiculous that new vehicles are such a crap shoot. I watched a TV show about ICE engines the other day. Invited in like 1880. 140 years later and your engine might blow at 1500 miles, lol. Short of pure abuse 2-300k miles should be a given.

Yep, it's hard to imagine with modern materials/metallurgy, CAD, precision manufacturing/robotics/CNC, synthetic oils, etc. that we just can't have some reasonable reliability expectations. I think corporate profits, government regulations, and the endless chase for a marginal increase in performance has led us to where we are now........spending record $$ and complaining on the Internet.

Well they do have about 900,000bad ones so far...yep probably lots more now that this has come out
