2015 Yukon XL, 5.3. Three times it has acted totally dead when I try to start. No lights, dash, nothing.
Had it jumped, did nothing. Replaced battery and it started. Second time (a month later) happened again.
Charged for a few hours and finally started. third time, wouldn't start again, dead. Was going to put seats down to get at something. When I engaged the power adjust button on the passenger front seat, all power came back and it worked fine. I touched the power adjust not thinking that all power was dead, surprise. After each of these episodes I get a message to recycle power windows.
So now, what do I do to figure this one out. don't want this to continue to happen but have no idea how to duplicate for a service center and have no idea what is not happening right????
