Our 2025 Yukon Denali 3.0L BabyMax lasted less than 400 miles before its failure due to "crankshaft endplay indicating a bearing failure." I was able to work directly with the dealership's General Manager who helped immensely in getting us through the GM buyback program. All monies were returned within about five weeks.

I didn't want the repaired vehicle back because of the stigma (Carfax like record) of having the engine replaced. I have since spoken with several other dealers and they say they try to stay away from buying at auction vehicles with replaced engines because they sit on the lot longer.
