APPROACHED AN INTERSECTION WITH A RED LIGHT WHILE DRIVING APPROXIMATELY 40MPH. WHEN I PRESSED MY BRAKES FROM ABOUT A BLOCK AWAY, MY 2001 LEXUS LS430 SUDDENLY SURGED. I HAD TWO FEET ON THE BRAKE AND ALSO TRIED TO PUT THE CAR IN NEUTRAL, THEN PARK. THE CAR DID NOT SLOW DOWN. WAS GOING APPROXIMATELY 50MPH WHEN I REAR-ENDED SOMEONE BECAUSE MY CAR WOULD NOT STOP. MY CAR WAS TOTALED, BOTH DRIVER AND PASSENGER AIRBAGS DEPLOYED. I WAS USING THE FLOOR MAT THAT CAME WITH THE VEHICLE AND IT WAS FASTENED. I FILED A COMPLAINT WITH TOYOTA THE DAY AFTER THE ACCIDENT, AND RECEIVED A RESPONSE ON JAN. 21, 2010. TOYOTA STATED IN THE LETTER THAT THEY FOUND NO STICKING OF THE ACCELERATOR AND THAT IT WAS VIRTUALLY IMPOSSIBLE FOR BOTH THE BRAKES AND THE THROTTLE TO FAIL AT THE SAME TIME. *TR
