The car was parked in line at my kid's school, waiting to pick him up. the car engine was turned off. when the car was turned on, warning lights for traction control, brakes and stabilitrak came on. after moving slightly forward, the car would not stop despite flooring the brake. luckily a speed bump stopped the car. we left the car where it was and we tried again the following day. the same lights came on and the brakes still completely unresponsive, the car coasted to a stop. the car was towed to the dealership. *tr
