We have had problems with our 2011 Sienna's electromagnetic coupling and the rear differential. Through my research, I have learned this is a very common problem with the Toyota Sienna. Appears the same problem occured in the RAV4 and a recall was issued, however an recall was not issued with the Sienna. The repair is very expensive, upwards for $4,000 and we had two electromagnetic couplings fail. Are there any potential action items we can take with Toyota. Kind regards,

Vehicle has a whining grinding noise, after having it serviced at Toyota Dealership, the finding has been a known issue for a few years: Rear Differential Viscous Coupling gone bad. If this is the same set up as the Toyota Rav and they issued a recall on it, What is the issue with not calling it for the Sienna's, especially when its a very known problem? Its a complete RIPOFF to the public, and something truly must be done. Thank you.

WAS DRIVING HOME FROM RUNNING ERRANDS, ABOUT A 4 MILE DRIVE AT 35 MILES/HR. AT A STOP LIGHT THERE SEEMED TO BE SOME SORT OF ELECTRICAL SURGE. ALL THE DASHBOARD LIGHTS FLASHED AND THE VEHICLE TURNED OFF. I WAS ABLE TO PUT THE CAR IN PARK AND RESTART IT. THERE WERE NO WARNING LIGHTS ON AFTER RESTARTING THE ENGINE, SO I ASSUMED IT WAS A FLUKE AND CONTINUED ON MY WAY HOME. A LITTLE FURTHER DOWN THE ROAD AT ANOTHER STOP LIGHT IT HAPPENED AGAIN. I PULLED INTO MY DRIVEWAY AND STARTED TO UNLOAD MY CAR WHEN I NOTICED SMOKE EMANATING FROM UNDER THE HOOD. I OPENED THE HOOD TO DISCOVER A SMALL FIRE COMING FROM A LARGE GROUP OF WRAPPED WIRES BEHIND THE BATTERY. I WAS ABLE TO PUT IT OUT QUICKLY WITH A FIRE EXTINGUISHER, BUT THE CAR IS COMPLETELY DEAD AND THE ENTIRE ELECTRICAL HARNESS NEEDS TO BE REPLACED AS WELL AS SOME OTHER NEARBY PARTS. THIS VEHICLE WAS WELL TAKEN CARE OF. THERE IS JUST UNDER 65,000 MILES ON IT AND I BROUGHT IT IN FOR IT'S 60K MAINTENANCE 6 MONTHS AGO (6/11/18). AT THAT TIME THEY ALSO TOOK CARE OF THE RECALLS FOR THE PASSENGER SIDE AIRBAG AND THE POWER SLIDING DOORS. SINCE I WAS ABLE TO CONTAIN THE FIRE QUICKLY, THIS VEHICLE SUFFERED MINIMAL ENGINE DAMAGE, SO I'M WONDERING IF IT SHOULD BE USED FOR INVESTIGATION PURPOSES BEFORE REPAIRS ARE MADE AS IT APPEARS THIS MAY HAVE HAPPENED WITH OTHER TOYOTA SIENNAS THAT SUFFERED MUCH GREATER DAMAGE.

"TAKADA RECALL" I AM WRITING BECAUSE MY TAKADA AIRBAGS HAVE BEEN UNDER RECALL FOR AN EXTENDED PERIOD OF TIME. EVERY SINGLE ATTEMPT (MULTIPLE ATTEMPTS) HAVE GONE UNRETURNED, DESPITE THE FACT THAT I HAVE CALLED 888-546-1750 ON MULTIPLE OCCASIONS! BECAUSE THIS RECALL AS THE POTENTIAL TO CAUSE EITHER INJURY OR DEATH, I WOULD THINK IT WOULD BE IN TAKADA, TOYOTA AND MY BEST INTEREST TO GET BACK TO ME. I AM VERY DISSATISFIED WITH THE RECALL AND VERY DISSATISFIED WITH HOW THE TOYOTA RECALL TEAM HAS NOT CONTACTED ME. THERE IS A SECOND RECALL ON THE DOORS FOR THE TOYOTA SIENNA. BECAUSE I CANNOT GET A HOLD OF THE RECALL TEAM, I CAN ALSO NOT SCHEDULE AN APPOINTMENT TO GET THIS RECALL ADDRESSED IN MY VEHICLE. THIS IS UNEXCUSABLE!

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

ON AUGUST 27, 2016 I WAS DRIVING OUR 2012 TOYOTA SIENNA ON AN INTERSTATE HIGHWAY. TRAFFIC WAS TERRIBLE AND I REAR-ENDED ANOTHER VEHICLE IN STOP-AND-GO TRAFFIC. THE IMPACT WAS MINOR, BUT THE ENGINE CAUGHT FIRE AND BURNT THE CAR TO THE FRAME. MY WIFE AND I WERE ABLE TO EXIT THE CAR BEFORE IT BURNED. WHEN I EXITED THE CAR, I TOOK MY KEYS WITH ME. HOWEVER, I WAS NOT ABLE TO OPEN ANY OF THE DOORS AND EVERYTHING I HAD IN THE BACK OF THE VAN BURNED. THANKFULLY, OUR CHILDREN WERE NOT IN THE CAR. IF THEY HAD BEEN, I WOULD HAVE NEEDED TO BREAK WINDOWS TO ATTEMPT TO REMOVE THEM FROM THE CAR.

MY SON WAS ATTEMPTING TO GET IN THE CAR AND MY HUSBAND, WHO WAS IN THE DRIVER'S SEAT AND WHO THOUGHT HE WAS ALREADY IN THE CAR, CLOSED THE SLIDING VAN DOOR BY PRESSING THE OVERHEAD REMOTE BUTTON. MY SON WAS TRAPPED, ARMS PINNED UP. THE DOOR DID NOT BOUNCE BACK. THIS IS NOT THE FIRST TIME THIS HAS HAPPENED, BUT IT IS THE FIRST TIME THAT IT WAS A CHILD (VS. SOMEONE LIKE ME, WHO IS STRONG ENOUGH TO STOP THE FORCE). I HAD TO RUN OUT AND FORCE THE DOOR BACK. THE LATCH WAS PIERCING HIS OTHER SIDE AND HE AND HIS TWIN SISTER (WHO WATCHED THE WHOLE THING, HELPLESSLY) WERE VERY FRIGHTENED. HE IS PROBABLY JUST BRUISED, BUT WHAT IF I HADN'T BEEN STANDING RIGHT THERE?! THE CAR WAS NOT ON, AND WAS PARKED IN OUR GARAGE.

AS I HAVE DRIVEN ON THE HIGHWAY, ON THREE SEPARATE OCCASIONS, MY REAR SLIDING DOORS HAVE SPONTANEOUSLY OPENED ON THEIR OWN. AFTER IT HAPPENED THE FIRST TIME, WE TURNED OFF THE AUTOMATIC DOOR FEATURE AND IT STILL HAPPENED ANOTHER TWO TIMES. WHEN WE TOOK IT INTO THE DEALERSHIP WE WERE INFORMED THAT THIS WAS A "KNOWN ISSUE WITH 2007-2011 TOYOTA SIENNA'S BUT THAT TOYOTA HAS NOT ACKNOWLEDGED AN ISSUE YET WITH 2012 SIENNA'S". WE WERE ALSO TOLD IT WOULD COST OVER $5000 FOR A PARTIAL FIX. WHEN I CALLED TOYOTA CORPORATION THEIR RESPONSE WAS "WHAT DO YOU WANT US TO DO ABOUT IT?

WE FIRST ENCOUNTERED A PROBLEM IN WHICH THE AUTOMATIC SLIDING DOOR WOULD NOT FUNCTION TO OPEN OR CLOSE AUTOMATICALLY BUT IT STILL WORKED MANUALLY. ABOUT A WEEK LATER THE REAR LATCH OF THE PASSENGER SLIDING DOOR BECAME STUCK IN THE LOCK POSITION THUS NOT ALLOWING THE DOOR TO FULLY CLOSE. I TOOK THE VEHICLE TO MY MECHANIC WHO GREASED THE LATCH AND ALLOWED IT TO FUNCTION PROPERLY HOWEVER THE DOOR WOULD STILL ONLY OPEN AUTOMATICALLY BUT WOULD OPEN OR CLOSE MANUALLY JUST FINE. DURING THIS TIME THERE WERE 3 INSTANCES WHEN THE DOOR WOULD AUTOMATICALLY OPEN WITHOUT HUMAN INTERVENTION BUT WHILE WE WERE DRIVING DOWN THE HIGHWAY WITH CHILDREN IN THE REAR SEATS. TOYOTA AGREES THIS IS A MAJOR SAFETY ISSUE BUT WILL ONLY SPLIT THE $1,200 BILL WITH US. BASED ON THE FACT THEY ARE WILLING TO HELP PAY FOR THE REPAIR OUT OF WARRANTY PROVES THEY ARE AWARE OF THE ISSUE YET FAIL TO ISSUE A RECALL AND PUT ARE WILLING TO RISK LIVES ESPECIALLY CHILDREN'S LIVES TO SAVE FACE.
