@carnau 2022 Yukon - a couple days ago I turned it off and everything shut off in the Yukon which isn’t normal. The radio and whatnot is supposed to stay on until the door opens or a couple minutes lapses. I quickly started it back up and got the open driver window -close driver window message. The next day I drive it and make a couple stops without issue. I go to work and come out after work to leave and it unlocks and lights up but will not start and then nothing turns on. Opened the hood, pulled the fuse panel cover off, closed it and actuators start going off so I know there is power. A do the same thing a couple more times and it finally starts, same message open/close windows. next morning I walk out, car lights up but will not start. It doesn’t recognize the key “key not found” even though the key was in it. It will start via remote start or GMC app. Try spare key same thing, key not found. Solution was to disconnect negative terminal, wait 10 minutes or so and reconnect and everything works. What in the world is going on? a few months ago I believe I had a slow battery drain and the Yukon would randomly die. Dealer tested circuits and what not for days and found nothing. I took the Yukon back and a couple weeks later did the same thing. Found a YouTube technician who said to have the dealer reflash it. Took it took the dealer and they did and Yukon seemed fine for at least 2 months until the above issue started. I’m wondering if the two issues are connected…
