NHTSA Complaint #10356299 — 2008 TOYOTA PRIUS

RAPID ACCELERATION WHILE CRUISE CONTROL ENGAGED. WHILE CRUISE CONTROL WAS SET FOR 68 MPH, I FOUND IT NECESSARY TO PASS A SEMI. WHILE THE CRUISE WAS ENGAGED THE ACCELERATOR WAS DEPRESSED AND I WAS ABLE TO PASS THE TRUCK NOT HAVING TO GO ANY FASTER THAN 73. SHORTLY AFTER, I BECAME AWARE THAT THE CAR WAS CONTINUING TO ACCELERATE AND I WAS UNABLE DISENGAGE CRUISE CONTROL BY BRAKING ONCE NORMALLY AND BRAKING ONCE HARD....THE ACCELERATION CONTINUED. SPEEDS WERE IN EXCESS OF 93+ AND I WAS FINALLY ABLE TO STOP THE ACCELERATION BY DISENGAGING THE CRUISE AT THE SWITCH. BRAKING SHOULD ALWAYS DISENGAGE CRUISE AND SHOULD HAVE SLOWED THE VEHICLE. IT DID NEITHER. FORTUNATELY I WAS ON AN OPEN FREEWAY....WITH ONLY WEATHER ISSUES....BUT THIS COULD HAVE BEEN VERY SERIOUS OR FATAL SHOULD TRAFFIC HAD BEEN STOPPED IN FRONT OF ME. *TR
