NHTSA Complaint #10523437 — 2008 MAZDA MAZDA3

TIRE VALVE STEMS FALL OUT OF THE TIRES: MY TIRES HAVE BEEN LEAKING AIR PERIODICALLY FOR ABOUT A YEAR. I NOTICED ONE OF THE TIRE VALVE STEMS WAS MISSING THE OUTER NUT COVER. WHEN I WENT TO ADD AIR TO THE TIRE, AIR CAME OUT AROUND THE VALVE STEM. I CAREFULLY DROVE TO MY GARAGE AND BEFORE I GOT THERE, THE ENTIRE VALVE STEM HAD BLOWN OUT OF THE TIRE. THE MECHANIC SAYS THE THREADS ON THE VALVE STEM WERE ALL OXIDIZED AND THE NUT ROTTED OFF. AFTER INSPECTING THE OTHER TIRES, WE NOTICED ANOTHER ONE WAS MISSING THE OUTER NUT ALSO AND HEAVILY OXIDIZED. I HAD THE MECHANIC PULL OFF ALL 4 TIRES AND INSTALL NEW VALVE STEMS TO ALL TIRES. I BELIEVE THIS TO BE A MAJOR ISSUE WITH MAZDA AND SEE PEOPLE COMPLAINING ALL OVER THE INTERNET AND A RECALL SHOULD BE CONSIDERED. *TR
