More often than not a 12 volt auxiliary battery failure.
That’s what I was thinking based on the numerous 12V issues we’ve seen in this board, but I would think GM would have known to suggest looking in to that first, so it’s interesting that the tik tok mentioned that GM was unable to help

Don’t most trickle chargers have to be plugged in to a wall outlet? I used to have one when I stored my C7 in the winter. Do they make portable ones? Just curious so if I go park at an airport for 5 days I could hook up a trickle charger so it isn’t dead when I get back from traveling
