I WAS PULLING INTO THE PARKING SPACE AFTER DRIVING THE VEHICLE FOR 45 MINS (APPROX. 20 MILES). WHEN I WAS READY PARK THE CAR AND SWITCH OFF THE IGNITION, THE CAR SUDDENLY ACCELERATED WAY TOO FAST AND HIT THE BUILDING IN FRONT. I WAS DRIVING INTO THE PARKING SPACE AT LESS THAN AROUND 10 MPH AS I HAD TO MAKE 3 TURNS WITHIN 100 FEET BEFORE COMING INTO VACANT PARKING SPACE. MY LEG WAS ALSO IN THE BREAK PEDAL AS I MADE THOSE TURNS AFTER GETTING INTO THE PRIVATE PROPERTY FROM IL RTE 83. I CAN DEFINITELY CONFIRM THAT MY LEG WAS NOT IN GAS PEDAL AS MY RIGHT LEG WAS ON THE BREAK PEDAL TO MAKE THOSE TURNS AND STOP THE CAR IN THE PARKING SPACE. IT ALL HAPPENED IN THE MATTER OF FEW SECONDS AND THERE WAS NO TIME TO REACT. THE CAR CAME TO HALT ONLY AFTER HITTING THE BUILDING. BOTH AIR BAGS DEPLOYED AS SOON AS THE CAR HIT THE BUILDING AND THERE WAS HEAVE SMOKE INSIDE THE CAR. IT WAS REALLY SCARY BECAUSE BY LOOKING AT THE DAMAGE THE SPEED AT THE TIME OF ACCIDENT LOOKS TO BE AROUND 50 MPH. IT WAS A RELATIVELY HIGHER CURB IN FRONT AND THE BUILDING WAS JUST 6 - 8 FEET AWAY FROM THE CURB, I WAS ALSO DRIVING INTO THE PARKING SPACE AT LESS THAN 10 MPH. I AM REALLY SHOCKED TO SEE THIS KIND OF UNINTENDED/SUDDEN ACCELERATION HAPPEN WITH HONDA ACCORD CARS WHICH COULD PROVE TO BE FATAL FOR THE DRIVER, PASSENGER AND PEDESTRIAN ALIKE. *TR
