VEHICLE WAS IN MOTOR ON A CITY STREET, THE PROBLEM WAS THAT IT WOULD NOT COME TO A COMPLETE STOP AFTER JUST HITTING THE ACCELERATOR. TO BETTER DESCRIBE THIS, IT WAS RUSH HOUR TRAFFIC AND TRAFFIC WAS MOVING VERY SLOW SO I WOULD HAVE TO HIT THE BREAKS AFTER JUST HITTING THE BREAKS TO MOVE FORWARD. THIS RESULTED IN AN ACCIDENT WHERE I REAR ENDED THE PERSON IN FRONT OF ME. AFTER MY VEHICLE WAS REPAIRED I HAD TO RETURN IT TO THE SHOP BECAUSE THERE AN UNKNOWN MECHANICAL ISSUE, AT THAT TIME I WAS TOLD THERE WAS A RECALL WITH THE ACCELERATOR. MY BEST ASSESSMENT IS THAT THIS MAY HAVE BEEN A CAUSE FOR THE ACCIDENT. WHEN I BROUGHT THE CAR TO THE DEALER I WAS TOLD THAT THE RECALL WAS NOT ACTIVE, I DON'T KNOW WHAT THAT MEANS BUT I WOULD LIKE IT INVESTIGATED AT THIS TIME, AS THIS ACCIDENT IS NOW AFFECTING MY DRIVERS INSURANCE.
