2017 GMC SIERRA 2500 Electrical System Problems

We were at a restaurant with friends we got back into the vehicle. I started up the vehicle and several electrical things happened. The service trailer brakes message came up, then the service power steering message came on. The engine was running but the tachometer didn’t work, or the oil pressure gauge. A couple other warning lights on the dash were on and stayed on. When I put it in reverse it wouldn’t move. When I put it in drive it would move forward. So we were stuck in our parking spot. We decided to put it in neutral and two of us pushed the truck out of the space into a busy street in hopes of getting home. Luckily none of us or the truck was hit by the people driving on the roadway. I put the transmission in drive and it would go into gear but not not...

When connect my trailer i get a service trailer brake system, then the stability waring start to show up and the brakes on the vehicle seem to act funny. Very unsafe while towing a trailer and kids in the truck. VERY UNSAFE

Break lights activate by them selves. Can be driving, parked, vehicle off. Parked and locked. The break lights activate randomly. Most recently car was parked in drivevway over the coarse of 2 days. Break lights came on and off until batteries were dead. When parked I Can hear clicking noise coming from under the hood periodically, not sure if related or not. Also noticed cruise control will shut its self off some times.

I REMOTE STARTED THE VEHICLE TO ALLOW IT TO WARM UP. THE REAR WINDOW DEFROSTER AUTOMATICALLY TURNED ON. AFTER A FEW MINUTES, I GOT INTO THE VEHICLE AND NOTICED A BURNING SMELL AS WELL AS SMOKE COMING OUT OF THE SQUARE CONTROL UNIT ON THE REAR SLIDING WINDOW. QUICKLY, I SHUT OFF THE VEHICLE IN CASE THERE WOULD BE A FIRE. AFTER DOING SOME RESEARCH, I NOTICED THAT THERE HAVE BEEN SEVERAL SIMILAR COMPLAINTS. OTHER PEOPLE HAVE REPORTED THAT THEY NOTICED REAR DEFROSTER WIRES GLOWING AND MELTING TRIM WHILE OTHER HAVE REPORTED SMOKE AND SUBSEQUENT SHATTERING OF THE REAR WINDOW. THIS HAPPENED ABOUT ONE MONTH AGO (I DO NOT HAVE THE EXACT DATE).
