My Shift To Park senor come on often and wouldn't let me turn the vehicle off. I have taken to dealership for repair. Long wait and because parts are back ordered due to numerous vehicles having this same problem. This has left me stranded in my vehicle and not able to turn it off and leave the vehicle. I feel this is unsafe and should be handled on a recall. I am now without a vehicle for who knows how long?

Something inside the wheel started smoking and my gmc app displayed low break fluid. I pulled over and had someone come out two days later. The breakpad had uneven wear and the caliper had a broken seal on it which in turn tore the caliper up! This was not a safe situation to have with 4 kids in the car. This car has been one problem after another !
