2023 GMC Yukon AT4 6.2L dead at 10K miles

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

Research the lemon laws for your state. Usually going that route gets a buyback - do a search on this forum and you’ll find threads where members went that route and it worked out well in the end.

Are you in a comparable loaner machine? Might look into a Lincoln Navigator, comparable machine but the Fords have their problems too.

No ETA on replacement engine.

This is the problem here. Having an "unlimited warranty" is small comfort when you are driving something that could strand you at any second and potentally/probably take months to fix while they sort it out and your payments and insurance continue. How much more confidence do you have in the replacement? Obviously having a new motor doesn't guarantee anything..... this WAS a new motor.

This is helpful. Appears Texas laws apply if truck not repaired within 30 days. Anyone have experience in TX?

30-day test​

You pass the 30-day test if your vehicle has been out of service for repair because of a defect covered by the original factory warranty:

• For a total of 30 days or more - not necessarily all at one time - during the first 24 months or 24,000 miles (if a comparable loaner vehicle was provided while the vehicle was being repaired, that time does not count toward the 30 days) a substantial defect still exists.

According to repairpal, the most reliable full size SUV for the past year is the Infinity QX80 and Nissan Armada which makes sense as they have been around for a long time.

With only 10K miles, my 2023 6.2L died and would not restart - conditions not ready to shift.
This is after my 2021 suburban had lifters fail after 23K miles.

My 2023 High Country with the 6.2L made it only 2,200 miles before catastrophic engine failure.

+1. I think the universe is telling you to buy a different brand, or an older well kept model with less issues.

It's sad to see a mfg that used to make top quality stuff go downhill. Cost cutting only goes to far.....

MPG cutting is a problem too. Lifters fail, torque converter shreds its aluminum cover, to meet govt mpg requirements, all at the expense of the end customer. Saves you some gas, but you end up paying GM for parts/repair instead, so they come out ahead.

I've run the numbers a few times in a back-of-the-napkin kind of way, being generous with the fuel savings assumptions of DFM at 10%, which of course it's not that effective. At best, it might save $2000 in fuel over 100K miles. But a single failure of the system will be a minimum $5000 repair if it happens out of warranty, and costs about the same to delete it, if it were even possible on the 2021+ rigs. I would gladly pay the extra $2000 in savings to not have the fear of AFM/DFM failing (or any of the other potential failures of the fuel-saving bits like tighter main bearing clearances) while my family and I are on the road. It's the primary reason why I STILL drive an '07 (No AFM) and a '12 (AFM mechanically deleted). I can afford a newer rig but I don't want the risk.
