ON APRIL 17, 2016 AT 3.30 PM WHILE FORWARD PARKING MY VEHICLE, I EXPERIENCED A SUDDEN UNCONTROLLED ACCELERATION, RESULTING IN THE VEHICLE IMPACTING THE WALL IN FRONT OF MY PARKING SPOT. THE WALL WAS APX. 20 FT FROM THE CAR AT THE TIME OF THIS INCIDENT. I HAD MY FOOT ON THE BRAKE DURING THE LATER STAGES OF THE PARKING MANEUVER AND SPEED WAS MINIMAL <5 KM/H). BEFORE COMING TO A STANDSTILL, THE ENGINE SPRUNG TO MAXIMUM RPM WITHOUT ME EVER TOUCHING THE ACCELERATOR. I DIDN'T HAVE TIME TO CONTROL IT AND THE BRAKES WERE ALSO INEFFECTIVE. UPON IMPACT THE DRIVER FRONT AIRBAG DEPLOYED AND THE HORN STARTED. I SWITCHED OFF THE ENGINE AND REMOVED THE KEYS. SEVERAL WITNESSES CAME FORWARD FOR ASSISTANCE, POLICE, AMBULANCE AND FIRE DEPARTMENT WERE ON SITE. A POLICE REPORT WAS FILED. THIS INCIDENT IS VERY CONCERNING; PEOPLE COULD HAVE BEEN SERIOUSLY INJURED HAD THIS HAPPENED IN ANOTHER LOCATION OR IF PASSERSBY WHERE PRESENT.
