When I'm driving at a slow speed turning the truck looses all power and the steering wheel jerks out of my hand, stabilitrak is on the display and it says roll down driver window and roll back up! it also looses all power just driving down the road no matter the speed! I have also been stopped at a stoplight and it lost all power wouldn't come back on so I had to get out pop the hood and bang I. the battery box and cables and it started again! very scary going 75 mph and it shuts off leaving you no steering no brakes no lights no nothing! sometimes it says power steering failure sometimes and sometimes it says stabilitrack problem at something about towing! the brakes were also affected no brakes

After using the remote starter while vehicle was parked in my driveway, I started to drive my grandson to school. A short distance from home smoke and sparks started to emit from the rear seat next to the sliding window and electric rear window defroster. As I pulled over the rear window panel on the passenger side burst. I assume from excessive heat generated by the rear window defroster.

GMC has refused to find a fix for the heater cord defect which is one of the main reason why I purchased the vehicle. I live in Idaho. GMC should compensate owners until fixed.

When reverse is activated at night, the backup camera comes on at full brightness and is not dimmable. The bright screen prevents view of the passenger side mirror and significantly reduces visibility in the driver side mirror while reversing. The screen cannot be deactivated and blinds the driver. This is an ongoing issue.
