PULLED INTO PARKING SPACE AND VEHICLE SUDDENLY ACCELERATED AND HOPPED ONTO CURB AND RAN INTO PILLAR AT A RESTAURANT. LUCKILY NOBODY WAS EATING ON THE SIDEWALK WHERE VAN ENDED UP. PLACED VEHICLE INTO PARK AND REMOVED FOOT FROM BRAKE AND VEHICLE CONTINUED TO LUNGE FORWARD. IMMEDIATELY HIT BRAKES AGAIN AND A BYSTANDER CAME TO DETERMINE WHAT WAS WRONG. TALKING TO BYSTANDER TO DETERMINE WHAT HAPPENED, I TOOK MY FOOT OFF BRAKE AGAIN AND VEHICLE LUNGED FORWARD (WHILE STILL IN PARK). DECIDED TO SHUT VEHICLE OFF AND HAVE IT TOWED TO A DEALERSHIP. I AM AWAITING A CALL FROM TOYOTA CUSTOMER EXPERIENCE CENTER TO SETUP AN INSPECTION, HOWEVER I WENT TO DEALERSHIP TO PICK UP SOME THINGS OUT OF THE CAR. I INSTRUCTED THE SERVICE AGENT THAT THE VAN WAS NOT TO BE DRIVEN UNTIL THE TOYOTA CUSTOMER EXPERIENCE CENTER INSPECTOR HAD A CHANCE TO LOOK AT THE VAN WITH ALL PARTIES. NEXT THING I KNOW THE SERVICE AGENT HAD PULLED THE VAN INTO THE SERVICE BAY FOR ME TO GRAB MY BELONGINGS OUT OF. I HOPE THIS DID NOT RUIN ANY DATA IN THE COMPUTER ABOUT WHAT HAPPENED IN THE PARKING LOT. *TR
