NHTSA Complaint #10250360 — 2005 TOYOTA HIGHLANDER

ON NOVEMBER 26TH 2008 WHILE TRAVELING EAST ON INTERSTATE 70 FROM DENVER, 75 MILE AN HOUR, AND APROX TWENTY MILES EAST OF BENNET COLORADO, WE EXPERIENCED BOTH FRONT AND REAR PASSENGER TIRE BLOWOUTS AT THE SAME TIME. THE BACK PASSENGERS TIRE WAS DESTROYED. WE WERE ABLE TO CHANGE IT OUT WITH OUR SPARE. THE FRONT PASSENGERS TIRE WAS EXTREMELY LOW (1" OFF PAVEMENT) AND HAD A BUBBLE ON THE SIDE WALL OF THE TIRE. IT HAD NOT BROKEN THE AIR SEAL AROUND THE RIM, AND SO WE WERE ABLE TO RETURN VERY SLOW BACK APROX .25 MILES TO AN EXIT AND RETRIEVE AIR FOR THAT TIRE. AS THE SIDE WALL BUBBLE GREW IN SIZE WE STOPPED THE AIR AT ABOUT TWENTY POUNDS. WE THEN RETURNED APROX TWENTY MILE BACK TO DENVER, TO A DISCOUNT TIRE STORE. WE THEN REPLACED ALL OF THE TIRES ON OUR 2005 TOYOTA HIGHLANDER. PRIOR TO DEPARTING ON THIS TRIP WE HAD ROTATED THE ORIGINAL TIRES AS WELL AS CHECKED AND CONFIRMED ALL AIR PRESSURES, (THE PRESSURE WAS CHECKED THIRTY MINUTES BEFORE LEAVING TOWN) WHEN CHECKING THE TIRES WE HAD HEARD A HISSING SOUND AT THE VALVE STEMS ON BOTH OF THE PASSENGER TIRES. THOUGHT THIS WAS JUST THE AIR HOSE, BUT NOW BELIEVE THAT THE VALVE STEMS WERE CRACKED AND LEAKING AIR. I HAVE DOCUMENTED THE TIRE CONDITION AND HAVE THE ORIGINAL VALVE STEMS FROM THE TIRE STORE. THESE TIRES WERE ORIGINAL EQUIPMENT MICHELIN TIRES WITH 28644 MILE ON THEM. WE BELIEVE THAT THIS CONDITION WAS A RESULT OF FAULTY VALVE STEMS, AND MAY BE A SERIOUS SAFETY CONCERN FOR OTHERS. MY TOYOTA DEALER SERVICE CENTER REFERS ME TO MICHELIN TIRE COMPANY, AND MICHELIN REFERS ME BACK TO THEM. TOYOTA MOTOR COMPANY HAS DOCUMENTED A REPORT, BUT WILL NOT ADDRESS THE ISSUE AS A CONCERN. WE HAD THREE ADULTS - (500 POUNDS) AND THREE SUIT CASES - (150 POUNDS) AND THEREFORE DON'T BELIEVE THAT AT 750 - 800 POUND THAT WE WERE OVERLOADED. *TR
