WE HAVE HAD EXTENSIVE PULLING PROBLEMS AND EXCESSIVE TIRE WEAR WITH OUR SIENNA FROM THE 2ND MONTH WE HAVE OWNED IT. THE TIRES ARE VERY WORN OUT ON THE OUTER EDGES WITH ONLY 18000 MILES. WE HAVE HAD IT INTO OUR DEALER 5 TIMES TO FIX THE PROBLEM. WE ARE AWARE AFTER DOING EXTENSIVE RESEARCH THROUGH THE INTERNET THAT MANY SIENNAS ON THE ROAD HAVE THIS PROBLEM AND TOYOTA IS AWARE OF IT, BUT CONTINUES TO PUT PEOPLE OFF. I LIVE IN THE NORTHWEST WHERE WE HAVE MANY RAINY DAYS AND MY VEHICLE IS UNSTABLE IN THE RAIN, WITH ALOT OF SLIPPAGE IN THE TIRES. THIS A KNOWN PROBLEM WITH THE SIENNA, AS EVIDENCED BY OUR RESEARCH THROUGH EDMUNDS.COM'S TOWN HALL WHICH IS A FORUM FOR PEOPLE WITH PROBLEM VEHICLES. NUMEROUS PEOPLE HAVE REPORTED EXCESSIVE TIRE WEAR WHICH IS UNSAFE AND A POTENTIAL HAZARD. THANK YOU FOR TAKING MY COMMENTS INTO CONSIDERATION. I KNOW I AM ONLY ONE PERSON, BUT THE I CONSIDER THE SAFETY OF MY CHILDREN IMPORTANT ENOUGH TO MAKE MY EXPERIENCES HEARD. THANK YOU, LAURIE A. SHANK. *AK

AT 65MPH, TIRE SENSOR INDICATED PROBLEM. UPON REMOVING THE FRONT LEFT FIRESTONE AFFINITY TIRE, FOUND A 7.5" SEPARATION BETWEEN THE TREAD AND THE INTERIOR SIDEWALL, WITH THE STEEL BELT IN VIEW. FURTHER INSPECTION REVEALED SIMILAR WEAR ON FRONT RIGHT TIRE. NORMAL PRESSURES AND ALIGNMENT HAD BEEN MAINTAINED THROUGH ROUTINE SERVICE. LOCAL FIRESTONE DEALER CLAIMS TIRE WAS NOT DEFECTIVE, DESPITE TOYOTA INDICATIONS TO THAT EFFECT AND SIMILAR EXPERIENCES WITH OTHER FIRESTONE TIRES. ALTHOUGH I HAVE REPLACED ALL FOUR TIRES, I HAVE RETAINED THE DEFECTIVE TIRE TO SUPPORT INVESTIGATION. DIGITAL PHOTOS OF THE TIRE ARE ALSO AVAILABLE. *AK (DOT NUMBER: W2VFAIT099 TIRESIZE: P215/65R15)
