NHTSA Complaint #10477984 — 2012 MAZDA MAZDA3

THE VEHICLE WILL RANDOMLY AND SPORADICALLY SPEED UP AND THE RPMS INCREASE UNEXPECTEDLY WHEN THE CLUTCH IS RELEASED AFTER DOWNSHIFTING FROM 3RD TO 2ND OR 4TH TO 3RD. MOSTLY FROM 3RD TO 2ND. THE VEHICLE REALLY PULLS FORWARD AND DOES NOT SLOW DOWN WHEN THIS IS HAPPENING. INSTINCT IS TO JUMP THE BRAKE, WHICH SLOWS THE CAR, DECREASES THE RPMS AND APPEARS TO STOP THE INCIDENT. THIS IS A DEFINITE SAFETY CONCERN, ESPECIALLY WITH SNOWY, ICY ROADS JUST AROUND THE CORNER. I HAVE BEEN UNABLE TO REPLICATE THIS AS IT IS SPORADIC. THIS HAS HAPPENED NUMEROUS TIMES SINCE FIRST DRIVING THIS VEHICLE JUNE, 02, 2012. MILEAGE,SPEED AND DATE OF OCCURRENCE ENTERED ARE APPROXIMATES AS SEVERAL INCIDENTS OCCURRED PRIOR TO THE START OF DOCUMENTING EACH ONE. THE STATE AND ZIP CODE ENTERED IN THE ADDRESS INFORMATION IS THE CLOSET ONE TO ME. I LIVE IN CANADA AND HAVE NOT BEEN ABLE TO FIND A NATIONAL SITE TO FORMALLY LODGE A COMPLAINT. *TR
