TL*THE CONTACT OWNS A 2008 TOYOTA SIENNA WITH DUNLOP SP4000 A/F P215/65S/R16 WITH DOT DA2HC4ER3807. WHILE BACKING OUT OF THE DRIVEWAY AT A LOW SPEED OF 5MPH THE VEHICLE APPEARED UNBALANCED FROM THE RIGHT TO THE LEFT. THE DRIVER OBSERVED THAT THE FRONT PASSENGER SIDE TIRE WAS DISENGAGED FROM THE RIM WITH APROXIMATELY 2/3 OF THE TIRE HANGING ONTO THE RIM. THE TIRE HAS NOT BEEN REPAIRED. THE CONTACT IS AWARE OF THE SAFERTY RISK DUE TO THE DEFECT. THE CURRENT AND FAILURE MILEAGES WERE 7,500.

TOYOTA EQUIPS AND SELLS THEIR SIENNA AWD VANS WITH DUNLOP SP SPORT 4000 P225/60R17 DSST RUN FLAT TIRES AND FAILS TO INFORM YOU THAT YOU WILL BE LUCKY TO GET 20-25,000 MILES ON THE TIRES. I HAD MY VAN SERVICED AND TIRES ROTATED EVERY 5,000 MILES AND NOT ONCE WAS I INFORMED THAT MY TIRES WERE WEARING OUT. AT 25K I HAD TO GET 4 NEW TIRES. TOYOTA DID PAY FOR 2 OF THE 4 BUT IT STILL COST ME $558. MY VAN WAS MANUFACTURED AFTER 09/05 SO I WAS NOT ELIGIBLE FOR TOTAL REPLACEMENT PER A CLASS ACTION LAW SUITE. *TR

I HAVE A 2005 TOYOTA SIENNA WITH ALL WHEEL DRIVE AND RUN-FLAT TIRES. I WAS TOLD THAT THE CAR HAS A TIRE PRESSURE MONITORING SYSTEM (TPMS). I HAD TWO EVENTS OF LOW TIRE PRESSURE THAT WENT UNDETECTED BY ME. BOTH TIMES I TOOK THE CAR TO THE DEALER WHO TOLD ME THE NOISE AND VIBRATION WAS DUE TO LOW TIRE PRESSURE. I TOLD THEM THAT I NEVER SAW THE LOW TIRE PRESSURE LIGHT ON THE DASHBOARD. THE LATEST EVENT WAS A BLOW-OUT OF THE LEFT FRONT RUN-FLAT TIRE ON HWY 85 IN CA. THE CAR WAS DIFFICULT TO HANDLE AND I SLOWED AND EXITED THE FREEWAY AND THERE WAS NEVER A TPMS WARNING LIGHT ON THE DASHBOARD TO INDICATE LOSS OF TIRE PRESSURE. THE TIRE WAS TOTALLY GONE. HAD TO COVER THE COST OF THAT REPAIR. I RECENTLY TOOK THE CAR BACK TO THE DEALER TO FIND OUT WHY THE TPMS WAS NOT WORKING. THE DEALER THEN TOLD ME THAT THE TPMS SYSTEM ON THE 2005 TOYOTA IS BASED ON THE ANTI-LOCK BRAKING SYSTEM AND USES THE SPEED OF TIRE ROTATION AND NOT DIRECT TIRE PRESSURE MEASUREMENTS. FURTHERMORE, THEY TOLD ME THAT THE TMPS WAS WORKING PERFECTLY. I FIND APPLICATION OF A TMPS BASED ON TIRE CIRCUMFERENCE WITH RUN-FLAT TIRES IS COMPLETELY USELESS. THERE IS NO WAY THE 2005 TOYOTA SIENNA TMPS WILL EVER WORK WITH RUN-FLAT TIRES. THE RUN-FLAT TIRES HAVE EXTREMELY STRONG SIDE-WALLS TO ALLOW THE CAR TO CONTINUE WITH LITTLE AIR PRESSURE BUT, THAT MEANS THE TIRE DOES NOT DEFORM WITH LOW TIRE PRESSURE. THE FACT THAT I HAD A TOTAL TIRE BLOWOUT WITHOUT A TMPS WARNING LIGHT SHOWING MEANS THE TMPS SYSTEM DOES NOT WORK. I FIND THIS SYSTEM TO BE UNSAFE AND I WANT TO KNOW WHAT IS BEING DONE AND HOW COULD THIS TMPS SYSTEM COMPLY WITH DEPARTMENT OF TRANSPORTATION RULE CFR CITATION: 49 CFR PARTS 571 AND 590; DOCKET ID: NHTSA 2000-8572, RIN ID 2127-A133? *TR

I HAVE A 2006 TOYOTA SIENNA XLE AWD MINIVAN WHICH WAS SEEN 10/17/07 FOR TIRE REPLACEMENT (DUNLOP 4000 DSST RUN FLATS). I HAVE OWNED THIS CARE FOR 1 YEAR AND 2 WEEKS AND HAVE ONLY 14,900 MILES ON IT. RECOMMENDED SERVICE HAS BEEN DONE AT THE DEALERSHIP TWICE SINCE I'VE OWNED THE CAR, INCLUDING TIRE ROTATION...ONCE IN FEBRUARY AND ONCE AT THE END OF JULY. THE CAR WAS DRIVEN ONLY UNDER NORMAL ROAD CONDITIONS AND AIR PRESSURES CHECKED EVERY 2 WEEKS. I AM TWO WEEKS PAST 1 YR. WARRANTY AND EVEN THOUGH PREEXISTING WEAR WAS "MISSED" BY SERVICE DEALER IN LATE JULY, I AM BEING CHARGED FOR REPLACEMENT. TOYOTA AWARE OR PREVIOUS PROBLEMS WITH THESE TIRES, INCLUDING CLASS ACTION LAW SUIT, YET CONTINUED TO PUT THEM ON CARS. MY TREAD WEAR WAS DETERMINED TO BE UNEVEN WITH 0 DEPTH ON THE INSIDE TREAD OF LEFT FRONT, POSING A SAFETY HAZARD AND CREATING AN UNSAFE DRIVING CONDITION. REPORT ALSO INDICATES WEAR ON EDGES AND CUPPING EVIDENT ON ALL OTHER TIRES (ACCORDING TO THE DEALER, MY VIN NUMBER DID NOT MATCH UP WITH THE "SERVICE BULLETIN" AND I WAS CHARGED FOR THE INSTALLATION OF THESE TIRES AND A WHEEL ALIGNMENT) AN ATTEMPT TO CONTACT TOYOTA CUSTOMER CARE WHILE THE CAR WAS IN THE SHOP WAS UNRESOLVED AS CUSTOMER CARE NEVER RETURNED MY CALL. RUN FLATS WERE SUPPOSED TO BE A SAFETY FEATURE ON MY AWD, INSTEAD THEY HAVE BECOME A SAFETY HAZARD. ONE DOES NOT CARRY A SPARE, AND IN FACT THERE IS NO ROOM FOR ONE IN THIS SIENNA. YOU WOULD NOT EXPECT TO NEED 4 NEW TIRES AT <15,000 MILES! *TR
