Consumer Description

- Traction control engaged at high speed(70 mph on interstate) causing the vehicle to brake abruptly and pull the vehicle to the right. Had I been traveling in the left hand lane, I could have been forced into the right hand lane causing a collusion with another vehicle. Also occurred at lower speed(30 mph on a windy road) causing the same issue as described above, almost causing the vehicle to leave the paved surface. - Mechanic was able to duplicate the issue - Mechanic diagnosed intermittent traction control activation, scanned computer for codes. Yaw rate/steering angle correlation causing false activation ABS/traction. Replaced hub bearing and spindle. Four wheel alignment, including check castor, camber and adjust toe. Performed zero point calibration and reset ABS memory. - Traction control lights up briefly
