The contact owns a 2012 Toyota Sienna. The contact stated that the rear differential was making an abnormal whirling and grinding sound. There were no warning lights illuminated. The contact called the local dealer but the vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to NHTSA. The approximate failure mileage was 79,000.

Vehicle began 'whirring' metal noise from underneath. Local mechanic said it was coming from rear differential. I took it to a Toyota dealer, they said rear differential coupler needs replacing ($2159) and drive shaft ($992). It seems the bearing ring inside this sealed unit has failed. Noise is continuous while driving, concern of part failure - we are taking vehicle on family vacation. Researching on - line it appears to be common problem with the Sienna's. Toyota had same issue with RAV 4's and issued recall but have not for the Sienna's. I called Toyota corporate in TX (got up 3 levels) to no avail, and it curt tone, they said they cannot help. Based on other similar stories on line from other Sienna owners, this seems to be a common very expensive design flaw problem with this vehicle.

WE REALIZED THAT OUR VEHICLE HAD A FLAT TIRE. WHEN WE WENT TO ATTEMPT TO PUT ON THE SPARE, WE NOTICED THAT ALL OF THE LUG NUTS HAD "SWOLLEN" AND NONE OF THE LUG NUTS WOULD FIT IN THE CORRESPONDING SOCKET. ULTIMATELY, THE LUG NUT CAPS DELAMINATED, AND IT TOOK OVER AN HOUR TO TEAR THE CAPS FROM THE NUTS. IF THIS HAD HAPPENED ON THE SIDE OF THE HIGHWAY, ADDRESSING THIS ISSUE WOULD HAVE BEEN INCREDIBLY DANGEROUS. IT DOES NOT SEEM TO MAKE SENSE TO CONTINUE USING LUG NUTS WITH DECORATIVE CAPS FOR AESTHETIC REASONS WHILE IMPACTING THE SAFETY OF DRIVERS WITH FLAT TIRES.

FRONT TIRES WEAR OUT TOO FAST ON THIS VEHICLE. I PURCHASED VEHICLE AROUND 60K MILES. NOW AT 130K AND ON 4TH SET OF TIRES. ALL MICHELIN/TOP QUALITY FROM COSTCO. ROTATIONS AT 5-7K RELIGIOUSLY. FRONT END SUSPENSION/STEERING IN GOOD SHAPE/PARTS REPLACED WHEN WEAR IS SEEN. ALIGNMENT GOOD. HORRIBLE. WEAR IS ON OUTER EDGES OF BOTH FRONT TIRES.
