I AM DRIVING FORWARD AT 55 MPH ON A MAIN ROAD IN THE CITY. THERE WERE ABSOLUTELY NO CARS IN FRONT, ON SIDES, OR BEHIND ME. THEN WARNING FLASHES ON DASH QUICKLY AND IMMEDIATELY AFTER WARNING DISPLAY MY CAR SLAMMED TO A STOP. I WAS SLAMMED FORWARD INTO THE STEERING WHEEL. IT WAS THE AUTOMATIC BRAKING SYSTEM THAT IS MALFUNCTIONING APPARENTLY.
