NHTSA Complaint #11084026 — 2010 MAZDA MAZDA3

WAS TRAVELING AT HIGHWAY SPEEDS ON THE BYPASS WHEN THE VALVE STEM AND TPMS SENSOR BROKE OFF AND IMMEDIATELY DEFLATED THE TIRE SHAKING THE VEHICLE VIOLENTLY AND ALMOST CAUSING DRIVER TO LOSE CONTROL. HAVE BROUGHT THIS COMPLAINT TO MAZDA IN THE PAST AND THEY SAID THEY KNOW THAT IT IS CAUSED BY USING DISSIMILAR METALS ON THE TPMS SENSOR CAUSING EROSION TO THE STEM AND ULTIMATELY THE STEM BREAKING OFF. THIS TPMS SENSOR WAS ALREADY REPLACED ON THE VEHICLE AT THE TIRE CHANGE INTERVAL AND STILL FAILED LONG BEFORE THE VEHICLE WAS DUE FOR ANOTHER SET OF TIRES. MAZDA KNOWS THESE ARE DEFECTIVE AND REFUSES TO DO ANYTHING ABOUT IT. I'D RATHER NOT HAVE TPMS AND NOT KNOW WHAT MY TIRE PRESSURES ARE THAN TO HAVE THAT SYSTEM ENDANGER MYSELF OR MY FAMILY ANY MORE. IT IS CURRENTLY MORE DANGEROUS TO USE THESE DEFECTIVE FAULTY TPMS SENSORS THAN IT IS TO NOT HAVE THEM. THAT SHOULD TELL YOU SOMETHING...
