The automatic brake assist locks up the right front wheel. The wheel still turns but the brake overheats and starts smoking after just a few minutes of driving. It was being driven on a city street at about 30 to 40 mph. Normal braking at stoplights and suddenly felt like a tire had gone flat. When I checked, the right front wheel was smoking. We had the calipers and pads replaced, but that did not fix the problem

Driving on the highway my car would not go. Car sensor prevented my car from moving because the wheel bearings went out on the used car I just purchased. The timing belt is also loose and the motor can seize up at any moment. My all wheel drive stopped working as well because of this. I had to put on my flashers and try to make it to an area where I could get off the highway. I called a tow truck. I have copies they will not download here, but available if needed.

While driving the stability track service lift comes on, the ABS, brakes, service all wheel drive, as well as the service power steering at which time I lose power steering. It also feels like it is accelerating sluggishly when drive sometimes. This happens and goes off sometimes with out me turning the car off or stopping but other times I have to pull over and wait a few minutes after turning the car off. It happens various times. At one moment it is driving fine and then these lights come on. When taken to dealership the lights have gone off and they get no codes. I was told the that it says a miscommunication and no code is recorded. The service light issues happen on city streets. The sluggish acceleration happens on both city and highway. I have been to the GMC dealer several times over the last 2-3 weeks.

Service stabilitrax. And light and transaction control. Sometimes followed by check engine light. Stabilitrax goes out, sometimes reducing speed and putting car into safe mode. I was driving on an interstate when the service stabilitrax, ABS and traction control lights came on. Weather conditions were wintery mix. When turning off highway, there was no traction control to kick in.

While driving traction control, AWD, and ABS system shuts off prompting to service stabilitrak. Upon taking the vehicle to dealer nothing is found. But im forced to drive without key safety features. My stopping time is drastically increased making it harder to feel safe knowing I have to drive in various weather conditions with out ABS. Even normal city driving has been nerve wrecking. I purchased this vehicle 8 days ago and have been back to the dealer 4 times for the same issue.
