I WAS PARKING IN MY USUAL PARKING SPOT IN A PARKING LOT AT MY OFFICE AT APPROXIMATELY 8:15 A.M. AS I APPROACHED MY PARKING SPOT, I SLOWED MY CAR BY PRESSING ON THE BRAKE AND MADE A 90 DEGREE TURN INTO MY PARKING SPOT. THE VEHICLE WAS SLOWING MOVING FORWARD AND WAS LESS THAN 10 FEET FROM WHERE I INTENDED TO STOP THE VEHICLE WHEN THE VEHICLE SUDDENLY ACCELERATED ON ITS OWN AND CRASHED INTO THE CONCRETE WALL THAT WAS AT THE BASE OF MY PARKING SPOT, CAUSING THE CAR'S AIRBAGS TO DEPLOY. I DID NOT HAVE MY FOOT ON THE ACCELERATOR PEDAL AT THE TIME THE VEHICLE ACCELERATED INTO THE WALL. I INFORMED TESLA OF THE INCIDENT AND THEY TOLD ME THAT THE VEHICLE HAD EXPERIENCED 100% ACCELERATION IMMEDIATELY PRIOR TO THE COLLISION WITH THE WALL.)
