WE PURCHASED A 2007 TOYOTA SIENNA XLE AWD IN MAY OF 2007. IN NOV 2007, THE LOW TIRE PRESSURE WARNING LIGHT CAME ON. I CHECKED THE TIRES AND THEY WERE IN FACT LOW. WE FILLED THE TIRES WITH AIR. A COUPLE OF WEEKS LATER, THE SAME THING HAPPENED. WE PUT AIR IN THE TIRES AND MADE AN APPOINTMENT TO BRING THE CAR INTO THE TOYOTA DEALERSHIP. TOYOTA OF BELLEVUE CHECKED THE TIRES WED DEC 5, 2007. THEY CHECKED ALL FOUR TIRES AND FOUND NOTHING WRONG. ON WED NIGHT MAY 28, 2008, THE SAME THING HAPPENED. THE RIGHT FRONT TIRE WAS AT OR BELOW 15 PSI, THE OTHER THREE TIRES WERE AT OR JUST UNDER 20 PSI. I FILLED ALL FOUR TIRES AND THE LIGHT WENT OUT (WHEN I FILLED THE RIGHT FRONT TIRE, I STARTED THE CAR TO SEE IF THE WARNING INDICATOR WOULD GO OUT; IT DID NOT GO OUT, UNTIL I FILLED ALL FOUR TIRES BACK UP TO NORMAL PRESSURE. ON MAY 31, 2008 WE BROUGHT THE CAR INTO TOYOTA OF BELLEVUE AND THEY TOOK ALL FOUR TIRES OFF AND INSPECTED, BUT FOUND NO PROBLEMS. THEY DID NOT REMOVE THE TIRES FROM THE RIMS, NOR DID THEY SUBMERGE THE TIRES IN WATER, NOR DID THEY REPLACE THE VALVE STEMS. THEY DID NOT FIND ANY FOREIGN OBJECTS THAT MAY HAVE PIERCED THE TIRES. CALLED DUNLOP TIRES ON 6/3/08 CASE#976284. ON 6/4/08 WE BROUGHT THE CAR INTO ELLIOTT TIRE & SERVICE. THEY REMOVED ALL OF THE TIRES AND CHECKED THEM. STATED IT COULD BE A FAULTY PRESSURE SENSOR. ON 8/31/08 ON WAY TO EVERETT, THE TIRE LIGHT CAME ON AGAIN. CAR SAT OUTSIDE AT NIGHT AND LIGHT IS STILL ON 9/1/08. AGAIN THE SAME THING HAPPENED IN JAN 2009. WE REQUESTED THE DEALER TO REPLACE THE WHOLE TIRE SENSOR SYSTEM REPEATEDLY. THEY REFUSED EVERY TIME. THIS CAR IS NOT SAFE. THE TIRE SENSORS ALLOW AIR TO LEAK AND THE TIRES BECOME LOW DESPITE THE FACT THAT WE FILL THEM EVERY WEEK. *TR

I WANT TO REPORT WHAT I BELIEVE TO BE A SAFETY/PRODUCT DEFECT WITH THE FOLLOWING TIRE: DUNLOP P225/60R17, 98T, M+S, SP4000T, DSST CTT THIS IS A SO-CALLED RUN-FLAT TIRE (INSTALLED APPROXIMATELY 12,000 MILES AGO) PER ORIGINAL EQUIPMENT SPECIFICATIONS ON MY 2006 TOYOTA SIENNA AWD MINIVAN. WITHIN THE PAST SIX WEEKS, (3) OF THESE TIRES RUPTURED SO BADLY THAT THEY HAD TO BE REPLACED. WITH THE FIRST BLOWOUT, I SURMISED THAT THE PROBLEM MIGHT BE DUE TO MICHIGAN'S NOTORIOUS ROAD POT HOLES. I WAS EVEN WILLING TO CONCEDE THIS MIGHT STILL BE THE REASON AFTER THE SECOND BLOWOUT. BUT WHEN THE THIRD OCCURRED TWO DAYS AGO, I CONCLUDED THAT A SERIOUS DEFECT WAS AT FAULT. NOTE THAT THE TIRES WERE PROPERLY-INFLATED ACCORDING TO THE STICKER ON THE DRIVER'S DOOR JAM STICKER (35 PSI). THOUGH IT WAS POSSIBLE TO DRIVE SLOWLY ON THESE RUPTURED TIRES TO A DEALER FOR REPLACEMENT, THE COST FOR NEW ONES IS VERY HIGH (~$250 EACH, INSTALLED). AS A CONSEQUENCE'AFTER THE THIRD BLOWOUT'I INSTALLED (4) CONVENTIONAL TIRES. MY TOTAL TIRE REPLACEMENT COSTS ARE NOW > $1000. I WOULD APPRECIATE YOUR CONTACTING ME ABOUT THE STATUS OF THIS PROBLEM. *TR
