Issue inside alarm goes off in the middle of the night. Get up the next morning the battery is dead. Thought battery was the issue replaced battery Monday same thing happens again inside alarm goes off battery dead in the morning. Take it to the shop again charge battery up nothing is wrong with the battery. Had old battery recharged and tested that one too. Again not the battery. Put old battery back in. Leave car in shop for over a week. Tested to be sure the NEW headlight that was just replaced isn't causing it, it's not. Same issue keeps happening. Can't drive my car at all. Tested for a draw on the battery sometimes there is one sometimes not. 32 codes were set. My Yukon is STILL in the shop no answer yet! Anyone else having this problem. I think the dam car is possessed! Headlights and brake light all going out for no apparent reason. Headlights have some moisture I think it is all connected some how. I have driven GMC's for years gonna fix this one a get rid of it no more Yukon's for me. This sucks have a beautiful truck but it is useless if I can't drive it!
