NHTSA Complaint #10525030 — 2010 MAZDA MAZDA3

THE DOCUMENTED DATE ABOVE (07/13/13) IS MY MOST RECENT INCIDENT WITH MY VALVE STEM/TIRE PRESSURE MONITORING SYSTEM FALLING OFF WHILE DRIVING. IN JUNE 2012 WITH ~34,000 MILES, WHILE DRIVING ON THE HIGHWAY, MY FIRST VALVE STEM/TPMS FELL OUT, NOT BEING ABLE TO DRIVE ON THAT WHEEL (NO AIR), AND THE WHEEL COULD NO LONGER BE USED UNTIL I HAD A MAZDA DEALER REPLACE THE PART. THIS WAS A VERY DANGEROUS EXPERIENCE FOR MY TIRE TO SUDDENLY DEFLATE WHILE MOVING AT FAST SPEEDS. THIS WAS FIXED UNDER MY ALMOST TERMINATED WARRANTY. ONE MONTH LATER, THE VALVE STEM/TPMS ON ANOTHER WHEEL CAME OFF WHILE DRIVING AND THIS HAD TO BE REPLACED LIKE THE OTHER ONE. MOST RECENTLY, MY THIRD WHEEL TPMSENSOR WENT WHILE ALSO DRIVING ON THE HIGHWAY, VIGILANTLY MAINTAINING CONTROL ON MY VEHICLE UNTIL I COULD PULL OFF THE HIGHWAY. THIS TREND SHOWS A HUGE SAFETY ISSUE/INADEQUATE PARTS USED DURING CONSTRUCTION. THERE IS NO PRESCRIBED CARE FOR THESE PARTS IN THE MAZDA OWNERS MANUAL NOR IS THERE ANYWAY TO KNOW THAT THESE WOULD MALFUNCTION UNTIL THEY DID. 3 OUT OF 4 IS UNACCEPTABLE AND UNSAFE AND SHOULD SHOW A TREND. WHEN I CALLED MAZDA, THEY TOLD ME THAT THE COST OF THIS RECENT REPAIR WAS MINE BECAUSE THE VEHICLE, NOW AT ~55,000 MILES WAS NO LONGER UNDER WARRANTY. THESE PARTS WERE DYSFUNCTIONAL FROM THE BEGINNING AND SHOULD HAVE ALL BEEN REPLACED AT MY FIRST INCIDENT IF THIS WAS TO HAPPEN AGAIN, AND AGAIN. I AM NERVOUS THAT THIS COULD HAPPEN TO MY FOURTH WHEEL WHILE DRIVING, POTENTIALLY CAUSING AN ACCIDENT. *TR
