There are 10 owner-reported air bags & restraints complaints for the 2010 Toyota Siennain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact's father owned a 2010 Toyota Sienna. The contact stated while his father was driving to the hospital at 30-40 MPH for a medical emergency, he lost consciousness. The vehicle crashed into a steel fence. The air bags failed to deploy. The contact's father was transported to the hospital by emergency units where it was diagnosed that he had sustained a broken neck, which made it impossible for the medical personnel to treat him. The contact's father deceased while in the hospital. A police report was filed. The vehicle was towed to a tow yard where it was totaled. The dealer was not notified of the failure. The manufacturer was not notified of the failure. The failure mileage was unknown.
One day when we tried to buckle the driver's side seat belt, little pieces flew out of the receiver side and it will no longer buckle. We took it to the Toyota dealer in N Syracuse NY and were told it would be a cost of $212 to replace and that it would be a two-week wait for the part to come in. This means that the owner and her two young babies would have to drive in an unsafe car, ILLEGALLY for two weeks putting her life and the life of her children in danger. The Toyota dealer inspected the seat belt and confirmed it was a defect and had failed. I called Toyota customer service and was told that there were no recalls for this defect and they would take no responsibility for the dangerous situation or consequences because the car was no longer under warranty. In fact, this is a problem that has been affecting many owners as indicated by an online search. Also, the fact that the dealer has to wait two weeks to obtain the part indicates that this seatbelt has failed many owners and they have used up the supply. This should be a recall situation but Toyota will take no responsibility.
SEAT BELT GETS STUCKED IN JAMMED AND WON'T RETRACT, EXTREME SAFETY HAZARD. CANNOT DRIVE WITHOUT WORKING SEAT BELT FRONT DRIVER SIDE. THIS HAPPENS FREQUENTLY AND I CAN'T GET IT ON JAM THIS TIME. THIS SHOULD BE A RECALL.
TL* THE CONTACT OWNS A 2010 TOYOTA SIENNA. WHILE OPERATING THE VEHICLE, THE PASSENGER SIDE AIR BAGS WERE DEACTIVATED EVEN THOUGH A 130 LB PASSENGER WAS SEATED IN THE FRONT PASSENGER SEAT. AFTER SWITCHING PASSENGERS, THE FRONT PASSENGER SIDE AIR BAG OPERATED NORMALLY FOR APPROXIMATELY 20 MINUTES BEFORE THE MALFUNCTION RECURRED, ALTHOUGH THE PASSENGER SEAT WEIGHED APPROXIMATELY 213 LBS.

THE DASHBOARD IS MELTING AND I AM NOT SURE IF THIS COMPROMISE THE AIRBAG DEPLOYMENT OR WILL CAUSE THE AIR BAG TO DEPLOY DUE TO THE RAPID DETERIORATION OF IT. *TR
