I've had a 2014 GMC since new with the small screen 96,00 mile. This happens often. Sometimes I lose the stations. Other times the engine fans run wide open or the heater control won't work, the AC comes on when I start the truck in the winter. These vehicles have the ability to turn things and then selves off/on through their Computer. Low Batteries, Cold, Heat, Heavy Electrical Loads all effect the Average DC voltage. The Computer even controls the rate of charge and How bite your head light are. These are random errors generated in possibly your CPU. ( RESET/Reboot) Turn off the Vehicle, let set 10 second, Restart it. If your condition clears reset the clock, radio stations, or turn off/on the AC. I hold a General Class FCC license in Electronics. I Call this normal. It could be as simple as weak battery or lose wire. Load testing the battery might determine its' condition. Consumer electronics only have to work correctly 85% of time. when it fails comply then you will be able to find it if it serous.
