NHTSA Complaint #10715970 — 2012 MAZDA CX-9

I EXPERIENCED UNEXPLAINED SUDDEN ACCELERATION WHILE STOPPED AT A STOP LIGHT. AT THE TIME OF THE INCIDENT THERE WAS ONE CAR STOPPED IN FRONT OF ME AND ONE BEHIND ME. FROM THE ONSET OF THE INCIDENT IT TOOK JUST A VERY FEW SECONDS, PROBABLY BETWEEN TWO AND FOUR, FOR THE ENGINE TO REV TO AN EXTREMELY HIGH SPEED. WHILE THIS WAS HAPPENINGS I COULD FEEL THE VEHICLE ATTEMPTING TO MOVE FORWARD FORCEFULLY WHILE I WAS APPLYING THE BRAKES VERY HARD. I SHIFTED INTO NEUTRAL AND TURNED OFF THE IGNITION. I THEN SHIFTED INTO PARK. I TURNED THE IGNITION ON AGAIN AND THE ENGINE CONTINUED TO REV AT A VERY HIGH SPEED. I IMMEDIATELY SHUT OFF THE ENGINE. I DECIDED TO START THE VEHICLE ONE MORE TIME. THIS TIME WHEN I TURNED ON THE IGNITION THE VEHICLE RAN NORMALLY. I CAUTIOUSLY DROVE IT FOR POSSIBLY FIVE MILES AND PARKED IT WHERE I COULD HAVE IT TOWED TO THE DEALERSHIP. I WAS ASKED ABOUT FLOOR MATS.THE ORIGINAL FLOOR MATS WERE IN THE VERY BACK OF THE VEHICLE AND I HAD WEATHERTECH MATS, IN THE FRONT OF THE CAR, WHICH WERE ATTACHED TO HOOKS IN THE FLOOR HOLDING THEN IN PLACE. THE DEALERSHIP DID TAKE THE SITUATION VERY SERIOUSLY. THEY DID INDICATED CONCERN ABOUT HAVING THE VEHICLE ON THE ROAD AGAIN. THEY TESTED THE VEHICLE FOR ANY COMPUTER CODES WHICH MIGHT INDICATE WHAT MAY HAVE CAUSED THE PROBLEM AND FOUND NOTHING. THEY CONTACTED MAZDA AND AT THE TIME THAT I SOLD THE CAR BACK TO THE DEALERSHIP THEY HAD NOT HEARD ANYTHING FROM MAZDA.
