I’m going to do more research myself and do what I can to prepare for whatever excuse GM tries to give me.

Called today and shared bulletin - so now parts are being ordered - 5 business days - and then dealership will call to schedule. The whole issue and it’s handling by GM and Dealership is a total joke. But what do you expect when you only pay $55k for a vehicle.

I have a 2020 High Country with this issue that was known to GM in 2019 and continues to exist. A shame to spend $60k on a vehicle that manufacturer recognizes problem, but will not repair. I have had vehicle to dealer three times for the issue. The first two times Dealer could not replicate issue. FINALLY, on third trip to Dealer, they agree that there is an issue, but no fix. I will begin process for manufacturer refund/replace, and move to file suit under lemon law if necessary. Very dissappointing as I really like the vehicle. https://www.gm-trucks.com/forums/top...h-only-in-2wd/

I immediately replied " you mean to tell me that the mechanic has read my description, not blown it off and passed it down the line, and wants to do the best he can to hear what i heard?" Yes sir" ".... **** tell em to take his ol lady to dinner in the damn thing yes he has my permission!!" They called the next day about the mentioned issue in the original post and sadly returned me truck unfixed. There is another 150 miles on the truck so I'm not mad at the dealership for doing their best to find it but sad that there's no path forward at this time.
