Good morning - my XT4 rolled off the assembly line on 4-23 and I took delivery on 6-26 and since then, I have had similiar issues PLUS the CUE system staying on often after I shut off the vehicle. It requires me to then get back in the truck, start it, and then turn it off again to shut down the CUE. Otherwise it keeps the entire interior system on. According to my selling dealership, GM is aware of the problem and is currently working on a software fix with no ETA in sight. I may have to lemon law it, and go for a Sport instead. Just by chance, do you have a premium lux version?
