On September 25, 2014, I was headed home from work traveling 45 miles per hour when the message stabilitraking off appeared on the dashboard. It was a clear and sunny day. As I continued to drive, my vehicle began to loose power and proceeded to slow down as I was in route. I immediately pulled to the side of the road and dashboard message was flashing stabilitraking off, service traction control, service stabilitraking, engine power is reduced then the engine shutdown and would not turnover. It would not make a sound. I called onstar service for towing. They did a diagnostic check at my request and the following codes were given: p0502, p0513, p0606 and p0700. After 45 minutes of waiting beside the road, I attempted to start the vehicle again and it cranked. However, still flashing the same messages above; it would not pick speed. The engine light never went off. I was only able to travel about 25 miles per hour and made it home safely. I had to have a towing company tow it from my yard to the dealer. I picked it up two days later from the dealer. They were unable to duplicate the problems, could find nothing wrong, cleared all codes and I picked up my vehicles and went home with no answers.
