Well Well Well. Looks like I'm not the only one GM has never seen this happen to before. On April 13, 2021 my 2021 Custom Trail Boss (5,000 miles) would not start. It sat for less than 18hrs from driving in the rain the previous day and had towed to the dealership. Next day they said they went to go look at it and she started right up. After looking at it for a week they could not find a single code or anything that could possibly be wrong. After so called going back and forth with GM engineers they supposedly looked at every connection and ground as well as do a hardware update. Well here it is May 4th and again it did not start as I was out the door at 0530 for work. Waited until the service department opened and talk to the girl who handled my file last time and said there is nothing she could do and GM does not have a repair at this time. All I can do is make the call to have it towed in and they will charge battery if needed. Damn thing will probably start by the time I get home. Why the hell do I have to worry if my $60k truck is gonna start?
