NHTSA Complaint #10490670 — 2012 MAZDA MAZDA3

MY 2012 MAZDA 3 SKYACTIV HATCHBACK WITH THE 6 SPEED MANUAL TRANSMISSION IS EXHIBITING UNINTENDED ACCELERATION. THE SYMPTOMS EXHIBITED ARE CONSISTENT WITH MULTIPLE OTHER REPORTS IN THIS SYSTEM. AFTER DOWNSHIFTING INTO 2ND OR 3RD GEAR, OR AFTER COASTING IN ONE OF THOSE GEARS WITH THE CLUTCH DISENGAGED, THE ENGINE REVS AND THE CAR "SURGES" FORWARD UPON RE-ENGAGEMENT OF THE CLUTCH. WHEN THIS OCCURS, THE ACCELERATOR PEDAL IS ONLY BEING SLIGHTLY PUSHED, BUT THE CAR ACTS AS IF IT HAS BEEN PUSHED ALMOST TO THE FLOOR. DEPENDING ON THE POSITION OF THE CLUTCH PEDAL WHEN THIS OCCURS, THE ENGINE WILL EITHER REV TO 3000 TO 4000 RPM, OR THE CAR WILL ACCELERATE FORWARD UNTIL EITHER THE BRAKE OR CLUTCH PEDAL IS PRESSED. THIS ISSUE HAS BEEN CONFIRMED BY MAZDA AFTER MULTIPLE TRIPS TO THE DEALERSHIP FOR SERVICE. UPON THE LAST VISIT, A DATA RECORDER WAS INSTALLED AND RECORDED 7 SPECIFIC UNINTENDED ACCELERATION EVENTS BETWEEN THE DATES OF 11/13/12 AND 11/20/12. ACCORDING TO AN EMAIL I RECEIVED FROM THE DISTRICT SERVICE & PARTS MANAGER FOR DISTRICT 2 OF MAZDA NORTH AMERICA OPERATIONS (MNAO) ON 12/23/12, "THE CONCERN FOUND ON THE DATA RECORDINGS TAKEN FROM YOUR VEHICLE WERE FOUND TO BE A PCM CALIBRATION ISSUE. MAZDA CORPORATION IS WORKING ON A NEW CALIBRATION FOR THE PCM WITH AN UNKNOWN TIME OF COMPLETION." WHEN I REQUESTED THAT MY VEHICLE BE REPLACED WITH ANOTHER OF THE SAME MODEL, THIS WAS THE RESPONSE FROM THE SAME DISTRICT SERVICE & PARTS MANAGER: "SINCE THE CALIBRATION OF THE PCM IS THE SAME ON A 2013 LIKE MODEL WITH A MANUAL TRANSMISSION IT WOULD NOT BE ADVISED TO TRADE YOU INTO THAT VEHICLE AS IT COULD POTENTIALLY EXHIBIT THE SAME CONCERN DEPENDING ON YOUR DRIVING HABITS AND CONDITIONS." I AM CURRENTLY AWAITING A RESPONSE FROM MNAO'S MEDIATION DEPARTMENT REGARDING EITHER REPLACING MY CAR WITH ANOTHER MODEL, OR BUYING BACK THE CAR FROM ME. *TR
