I WAS DRIVING INTO MY GARAGE WITH MY FOOT ON THE BRAKE WHEN CAR ACCELERATED TO FULL SPEEDC. I APPLIED FULL PRESSURE TO BRAKE. CAR FAILED TO STOP. CAR ONLY STOPED WHEN I PUT SHIFT LEVER IN NEUTERAL AFTER GOING THROUGH REAR WALL OF GARAGE. IF SOMEONE HAD BEEN IN FRONT OF THE CAR THEY WOULD HAVE BEEN KILLED.
