2012 TOYOTA SIENNA Complaints

SAYS MY REAR DIFFERENTIAL - VISCOUS COUPLER- IS BAD AND NEEDS TO BE REPLACED AT A COST OOF AT LEAST $1,300 AND THAT DOESN'T INCLUDE INSTALLATION. HAPPENED JUST AS CAR WENT OVER 100,000 MILES AND IS COVERED IN RAV 4 BC HAD SAME PROBLEM BUT NOT 2012 SIENNA NOTHING HAPPENED EXCEPT IT SUDDENLY STARTED NOT BECAUSE OF ANYTHING I DID.

THE REAR VISCOUS COUPLER ON THE AWD HAD GONE BAD AND NEEDS REPLACEMENT. THIS PART IS THE SAME DEFECTIVE PART ON THE RAV 4 THAT HAD AN EXTENDED WARRANTY COVERAGE DUE TO BAD DESIGN BUT IS NOT COVERED ON THE SIENNA. THIS PART NEEDS A RECALL.

THE BEARING FOR THE VISCOUS COUPLER HAS GONE BAD. IT WHINES LOUDLY WHEN IN MOTION, AND THE VOLUME CORRELATES WITH THE SPEED. ACCORDING TO FEEDBACK FROM ONLINE THIS ISSUE HAPPENS A LOT. TOYOTA WILL NOT CHANGE THE BEARING ($50 PLUS LABOR). THEY WILL ONLY CHANGE THE WHOLE COUPLER ($1800 PLUS LABOR) AS THEY STATE THE COUPLER IS NOT SERVICEABLE. MULTIPLE PEOPLE HAVE SERVICED THE WORKING COUPLER TO CHANGE JUST THE BEARING. TOYOTA RELEASED A SIMILAR TSB FOR THE RAV 4 WHERE THE COUPLER FAILED.

2012 TOYOTA SIENNA AWD HAS EXCESSIVE PREMATURE WEAR ON TIRES. NEW SET OF TIRES, FOLLOWING MANUFACTURES RECOMMENDED MAINTENANCE, HAS CONSUMED A SET OF TIRES IN UNDER 20,000 MILES. DRIVING CONDITIONS WERE NORMAL IN-TOWN OPERATIONS, MAINTAINED RECOMMENDED TIRE INFLATION, ROTATION.

2012 TOYOTA SIENNA DEVELOPED A "CLUNK" IN STEERING SYSTEM WHILE TURNING FROM A STOPPED POSITION. THE CLUNK CAN BE FELT THROUGH BOTH THE STEERING WHEEL AND FLOOR. THIS IS CAUSED BY A WELL-KNOWN SAFETY PROBLEM TOYOTA HAS HAD WITH SEVERAL OTHER MODELS INCLUDING RAV4, HIGHLANDER, AND CAMRY (SOME OF WHICH HAD RECALLS). TOYOTA IS PUSHING THE COST OF THEIR MISTAKES ON ITS CUSTOMERS. THIS IS AN ONGOING PROBLEM, ALONG WITH OTHERS, WITH TOYOTA.

MY 2012 SIENNA AWD XLE HAS 103K MILES AND HAS A WHIRRING NOISE COMING FROM THE REAR DIFFERENTIAL AREA FOR A WHILE NOW. THE PITCH AND VOLUME IS PROPORTIONAL TO SPEED AND IS LOUDER AS SPEED INCREASES. MY RESEARCH TELLS ME THIS IS A COMMON DEFECT WITH THE COUPLING BEARINGS IN FRONT OF THE REAR DIFFERENTIAL. IT SEEMS THAT RAV4 OWNERS GOT A RECALL FOR THE SAME ISSUE, BUT SIENNA OWNERS DID NOT. TOYOTA HAS REDESIGNED THIS PART ON LATER MODELS TO AVOID THE ISSUE. HOPE YOU CAN GET THIS RESOLVED. THANKS.
