GM 6.2 engine problems recall

[ORVietVet]

I also belong to another forum owned by the same owners here, @Shaggy and @Griffin, Tahoe/Yukon Forum. Back on April 25th a thread was started there, that has to do with 6.2 engine failures and the GM recall is for those engines in 2021 thru 2024 and involves either a complete engine replacement or a switch of oil weight from 0W-20 to 0W-40. As of a little while ago the thread count is at 1470 posts about the problem and that is an average of over 36 posts a day. There has been some false info spread and lots of owners dreading what will happen and even some of the 2025 year owners wondering if they should worry too.

Yea, buying new can be exciting but buying dependability with the GMT800 trucks gives me great comfort. Even my girl's 2002 TrailBlazer is rock solid. The costs related to a new vehicle purchase is daunting at best and the list of concerns mount up, sometimes daily. Too much "gizmos and gadgets". I love the vast majority of GM products but not all of them.

I was joking with my buddy. I was telling him I was hoping to be driving these newer trucks...in like 20 years+. I was like, "what am I supposed to driving then!?"

His response: "...your GMT800s, of course!"

LMAO

I have 27k miles on my 2025 2500hd and my ac doesn’t work, blows hot air 90% of the time

What?!

My wife sent a photo a few years ago of a recent Ford Explorer with a window AC hanging from the side window. I found it odd, because it's usually old vehicles you see this one, not recent models, but now I think I know why. SMH.

In all seriousness though... let's say it was a manufacturing defect with the crankshaft (maybe something about the surface roughness and/or polishing)? I think I heard something like that?

If you could get a vehicle that hasn't had an engine failed (yet), you'd be replacing the crank and bearings at minimum. If the engine already failed, then you will be looking at a 5.3 (or whatever is out there in the junkyards) or a 6.2 shortblock, right? I'm sure at some point, someone will be producing NEW blocks and rotating assemblies to be drop-in replacements for those that get denied coverage, for whatever reason(?)

I mean, surely "some" of these vehicles will be worth being put back on road? I can't imagine folks junking, otherwise serviceable vehicles? Engine replacement doesn't necessarily mean vehicle is sent to the crusher.

I agree. I think there is some sort of choice thing about a short block or long block swap. The short/long blocks that come out will be out there in some way, for others to buy up. Unless GM gets all them shipped to a location or 2 to re-machine and sell as short/long blocks, one way or another.
