Intermittently while driving the vehicle will suddenly engage the traction control (TC)/electronic stability control (ESC). The light flashes for a short period (probably no more than a couple of seconds) and the car slightly jerks to the right. A loud noise is heard when this happens and the brake pedal shakes. Then the light will stop flashing and the car will begin operating normally again. Typically, the problem will reoccur shortly after it happens. I took the car to a dealer, and the dealer was unable to replicate the problem. The service manager stated that there were no codes and no history, and without a code the problem could not be diagnosed. This problem occurred multiple times over the last few months.
