Wiring problems of the 2006 Toyota Sienna

2006 Toyota Sienna. Consumer writes in regards to repair cost concerning air bag and seat belt issues the consumer stated the air bag light illuminated. The vehicle was taken to the dealer for an inspection. The service advisor, informed the consumer it would cost $ 3,985 to repair the air bag issue, but stated it was a seat belt issue that required a floor wiring harness which needed to be replaced.

Our Toyota Sienna 2006 airbag light had been going on and off on the instrument panel. Took it to the Toyota dealership, they insist they have never heard of this problem. There are multiple complaints on the internet for this model and year. Not to mention other models being recalled for the same problem. . They are not diagnosing the cause but trying to replace the entire system. (wiring harness, sensors and airbags) I believe an investigation as to the faulty component or components are in order. Are the replacement parts they are wanting to use the same as they faulty ones. Are any of they airbag components in the Sienna the same as the Toyota highlander. (sensors chips, wiring harness). The dealership says they are using the same components that were originally were installed. Have read multiple forum complaints of people on there second or third total replacement of the entire airbag system. The dealership said it could take one to two months to get the parts because of national shortage. Again a shortage, are too many Siennas have the same problem, or are the components that are faulty similar to the highlander and are being used in that recall.

The air bag warning light came on. I took the vehicle into the dealership to have it looked at. The result was that the wiring harness for the seat sensor on the passenger side has corroded creating an open circuit. They gave me an estimate to replace the wiring harness and air bag (which has been apparently damaged due to the corroded harness) to a total of $3,000. Wiring harnesses do no€™t corrode in 5 years unless the part was defective at installation. Since the srs system is a major part of the vehicle'€™s safety systems and the system was designed to operate as a whole, repair is mandatory in order to insure occupant safety. Searching the internet there are literally 100s of instances of the exact same issue with the 2006 and 2007 model years. The fact that this issue is a fault in the vehicle€™s safety system and the high incident of this failure occurring I believe justifies a recall for repair of the system by the manufacturer.

2006 Toyota Sienna (approx. 89,000 miles) suddenly had flashing airbag light come on April 25, 2011. Vehile is single owner, personal use. Never involved in any accidents. Took to dealer, was told that air bag harness and front airbag wiring was bad, entire system would need replaced for about $2,400. Spoke with Toyota corporate office, they offered to by for 50% of repair. Had service manager at dealership contact district service parts manager to appeal for additional funding from Toyota, again was told that only 50% of cost would be covered by Toyota. This issue is related to faulty wiring/parts and not to milage, which is what I am repeatedly told is the reason the repair is not covered (out of 5 year/60,000 mile warrenty window).
