JUST AS I PUT MY NEW TOYOTA 4-RUNNER IN REVERSE IN A CROWDED PARKING LOT, THE ENGINE RACES WILDLY. FORTUNATELY MY FOOT WAS FIRMLY ON THE BRAKE, AND I WAS ABLE TO GET IT BACK INTO "PARK" - WHEREUPON THE ENGINE RACED EVEN MORE WILDLY, UNTIL I TURNED OFF THE IGNITION. I CHECKED TO MAKE SURE THAT NOTHING WAS AGAINST THE ACCELERATOR PEDAL - AND THERE WASN'T... I CHECKED TO MAKE SURE THE ACCELERATOR PEDAL WAS IN ITS CORRECT POSITION AND WORKING FREELY - AND IT WAS. SO I RESTARTED THE CAR, IT SEEMED FINE, AND DROVE HOME - AND A LITTLE BIT YESTERDAY (MONDAY) MORNING - THE DAY AFTER THE INCIDENT. ALL WAS FINE... BUT, BUT, THIS WAS A VERY CROWDED PARKING LOT WHERE THE INCIDENT TOOK PLACE - LITERALLY HUNDREDS OF PEOPLE - INCLUDING CHILDREN - WALKING AROUND, AND MANY HUNDREDS OF OTHER CARS AND TRUCKS NEARBY... I AM A LIFE-LONG TOYOTA OWNER - AND THIS WILL NOT CHANGE THIS. BUT, CLEARLY THIS "UNCONTROLLED ACCELERATION" PROBLEM WITH TOYOTA'S OF LATE, STILL EXISTS AND MUST BE CORRECTED IMMEDIATELY!!! *TR
SUDDEN RAPID ACCELERATION, ENTERING A PARKING SPOT, BOTH FEET ON BRAKES, STILL ACCELERATION, PUT IN NEUTRAL THEN PARK, STILL ACCELERATION, HAD TO BACK UP, WAS IN A BAD POSITION, NEVER TOUCHED THE GAS THRU THIS WHOLE INCIDENT. RELINED VEHICLE, STILL ACCELERATION, PUT IN PARK AND TURNED IT OFF. TOYOTA HAS HAD IT SINCE, 9-2-2011, TODAY IS 9-7-2011. WHAT ARE MY OPTIONS.
