I just got the call from the dealership. My truck is ready. I stopped by there the other day and spoke to the technician. He had them order parts for all cylinders so the top of the engine was completely tore down while I was there.
GM suggested that I test drive the truck with the technician so I could point out anything that I thought was not normal.
I also spoke to GM about lemon law and options. They said they were working on rebuilding trust in GM vehicles and were willing to discuss reimbursement option if I decided not to follow the lemon law route.
If all is well and accepted, it will have been at the dealership for 38 days.
As far as getting another truck, from talking to technicians and GM, 2022 "might" have it corrected. So, I think it is best to wait.
