While the contact's friend was pulling into a parking lot she pressed on the brake pedal and it hesitated while stopping the vehicle. On a separate occasion, while stopping at a stop light the accelerator pedal got stuck. This caused the contact's vehicle to rear end the vehicle in front. When the brake pedal was pressed the vehicle was non responsive. The contact had to turn the vehicle off to get it to stop. No injuries reported. The vehicle has not been to a dealership to be inspected concerning this problem.
