NHTSA Complaint #10513744 — 2008 MAZDA MAZDA3

THE FIRST TIME THIS HAPPENED, I WAS DRIVING ON THE HIGHWAY AT APPROXIMATELY 75 MPH IN THE CENTER LANE OF AN EXPRESS ROAD. WHILE DRIVING, THE TPMS SENSOR WARNING LIGHT/SOUND CAME ON AND THE TIRE WENT IMMEDIATELY FLATE - TOTAL CATASTROPHIC FAILURE. I WAS ABLE TO PULL OFF TO THE SIDE OF THE ROAD WITHOUT FURTHER INCIDENT AND WHEN WE LOOKED AT THE TIRE, THE TPMS SENSOR HAD FALLEN OUT CAUSING THE TIRE TO GO FLAT (IT IS ATTACHED TO THE VALVE STEM) THE TREADS WERE CORRODED AND THE NUT CRACKED CAUSING THE SENSOR FALL OUT AND THE TIRE TO GO FLAT. THIS ONE WAS REPLACED. 8 MONTHS LATER, THE SAME THING HAPPENED BUT THIS TIME ON THE DRIVER'S SIDE FRONT TIRE. THE NUT CRACKED AND THE SENSOR FELL OUT CAUSING THE TIRE TO GO FLAT. THANKFULLY THIS TIME IT HAPPENED JUST AFTER I HAD PULLED OFF THE HIGHWAY FOR A BATHROOM BREAK AND WAS NOT DRIVING AT SPEED WHEN THE SECOND INCIDENT OCCURRED - ALTHOUGH IF IT HAD HAPPENED A FEW MINUTES PRIOR, I WOULD HAVE BEEN DRIVING AT APPROXIMATELY 75 MPH IN WET ROAD CONDITIONS. UPON EXAMINATION WE FOUND THAT THE THREAD WERE AGAIN CORRODED, CAUSING THE NUT TO CRACK AND THE SENSOR TO FALL OUT. THIS IS A VERY DANGEROUS SITUATION - CATASTROPHIC FAILURE OF A TIRE AT HIGHWAY SPEEDS IS A RECIPE FOR DISASTER. THIS SITUATION SHOULD BE TAKEN VERY SERIOUSLY BY MAZDA. *TR
