I WAS INVOLVED IN A MOTOR VEHICLE ACCIDENT ON 4/25/10 WITH A 1993 LEXUS SC400 VIN# [XXX] . I WAS APPROACHING A RED LIGHT CONTROLLED INTERSECTION WITH MY FOOT ON THE BRAKE PEDAL AND THE VEHICLE CONTINUED TO ACCELERATE THROUGH THE INTERSECTION. I FEEL THAT THE COMPUTER CHIP CONTROLLING EITHER THE TRANSMISSION OR IDLING SPEED FAILED AS THE VEHICLE COULD NOT COME TO A HALT AND RESULTED IN A COLLISION. THE TRANSMISSION FAILED TO DROP DOWN TO NEUTRAL AND/OR THE IDLE COULD NOT DROP DOWN TO LESS THAN 1000 RPM. I REALIZE IT IS AN OLDER VEHICLE AND COMPUTER CHIPS COULD FAIL DUE TO AGE BUT I WONDER IF THIS COULD BE A DESIGN FLAW OF THE FAIL SAFE ACCELERATOR ASSEMBLY. COULD YOU LET ME KNOW IF ANY OTHER COMPLAINTS HAVE BEEN LODGED. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
