2023 GMC Yukon AT4 6.2L dead at 10K miles

My truck needs a whole new engine it appears. Buy back case initiated w GM

Dealer confirmed metal bits in oil pan. Engine is a goner. No ETA on replacement engine.

So, not lifters, likely bottom end issue?? Crazy, seems like they got the lifters squared away and now blew the bottom end components?

Seems to be just the 6.2 having bottom end problems. I could be wrong, but I don’t think I’ve heard of low mileage spun mains on the 5.3.

Both have had their fair share of DFM lifter failures.

Thats what I think too...and seems to be more in the 2023 model year than others?

Only asking as I am sporting around in my 2022 w/ the 6.2...
Up side I have is my dealer includes "unlimited powertrain warranty" on every car they sell...I've read the contract...net is: Internally lubricated parts for engine, transfer case, transmission, and differentials...which in the case of this rig...is a really good thing to have!

Their lifter issues seem to be getting worse, not better, as one would expect‍.

 

[Dangler6131]

I think mine is a spun bearing

GM cannot even tell me an ETA on a new engine…amazing.

You will likely get faster resolution through the buyback process. I would not try to stay with that particular rig. GM will buy you out and then fix it on their own time to later resell.

I have tried to open a buy back claim. GM telling me they want to fix it.
