Sienna 6-cyl

  • 30,000 miles


Had the air bag light go on and off for a while, and was told that when air bag light is on, the passanger airbags does not work. When the light went on and stayed on, I took it to the dealership. They said that it has faulty wiring and it will cause all airbags not to work, and the wiring would need to be replaced for $3000. After seeing all the complaints online with the 2006 Sienna with the same issue, it is obvious this is a quality and safety issue that should be addressed. I am just thankful we did not get in a accident, and hope toyato or the government steps in before something like that will happen thinking that it is just the passanger side airbag.

The contact owns a 2006 Toyota Sienna. The contact stated that while parked, the air bag light illuminated on the instrument panel. The vehicle was taken to an authorized dealer for a diagnostic test and the technician stated that the front driver's side air bag would have to be replaced. The air bag was replaced. The air bag warning light continued to illuminate. The vehicle was taken back to the dealer and the technician stated that the passenger side air bag would have to be replaced. The vehicle was not repaired a second time. The approximate failure mileage was 75,000.

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.

I had no idea so many other 2006 Sienna owners have air bag problems like I do. The first replacement was after only 8 months of ownership. The dealer replaced the entire front passenger seat assembly. Since then the air bag light went off and on with no pattern to its frequency and has been on continually for at least 6 months despite removing the drawer and inspecting/disconnecting/reconnecting the connectors. Right now a piece of black electrical tape covers the light on the dashboard since the dealer will charge $3000 to replace what has already been replaced and did not fix the problem. Air bags are not covered under the extended warranty. I feel like I have to tell my front seat passengers that they may not have an air bag protecting them and may feel safer in the rear seats. Toyota has a reputation for safety and I am surprised that the company has not done more to fix the air bag problems on 2006 Siennas. We bought our Sienna knowing we would soon have 3 teen/young adult drivers in the family and we wanted a vehicle that would protect all of us, no matter who is driving or sitting in the passenger seat.

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 not 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 vehicles safety system and the high incident of this failure occurring I believe justifies a recall for repair of the system by the manufacturer.

Sienna 6-cyl

  • 69,900 miles
Airbag warning light appeared on dashboard suddenly. Dealership ran diagnostics and said that a loose connection below the car seat could be the reason, as that fixed the warning light issue. Car's extended warranty expires in about 8months, and reading the most complaints on this mini-van being airbag issue, I am worried that the actual error (requiring replacement of the whole system $2K-$3K+ that others are paying) would appear right after my warranty expires. Toyota should really consider this as a re-call, or, extend the warranty of the airbag systems to 10yrs (regardless of mileage) to provide the security to 2006 Sienna owners.

Sienna 6-cyl

  • 46,890 miles
Air bag light on instrument panel flashes on and off. The vehicle was taken to a local mechanic who diagnosed a defective air bag sensor, which needs to be replaced along with the air bag and airbag harness under the driver's seat since the air bag would not deploy in the event of a crash, which could result in serious injury or death. Vehicle has only 47000miles on it but since it is over 5years it is not covered under warranty. This malfunction is not the result of any accident or bump, it started on its own. This issue has been reported on numerous vehicles and for no apparent reason. This is a serious defect in the SRS and a critical safety issue. It is in fact a clear violation of basic federal safety standards that should be taken care by Toyota.

My 2006 Toyota Sienna had to have 3 airbag components replaced in the first 17 months because of failure of the sensor, ECU and airbag assembly. These were replaced under warranty. Now that the car is 5 years and 1 month old the other front airbag assembly malfunctioned and Toyota has refused to pay to repair it. The warranty was for 5 years and 50,000 miles. I now have no functioning airbags because when 1 airbag does not work the computer turns all of them off.

Air bag light would sometimes come on and stay on, but usually only for a day or two. In November 2011 the light came back on and stayed on for several days. We just took the van to leith Toyota in raleigh, nc for a diagnostic and said they found historical codes for the front left passenger air bag and "current" codes for the front driver air bag. They said the only fix is to replace the entire air bag assembly for $3000 (per side). The van is worth maybe $12,000 and now we are told we have to spend a total of $6,000 for both sides to completely fix the problem. Turns out the 2006 Toyota Sienna has hundreds of complaints filed at various locations for the same air bag issue. Toyota has a tsb out for the issue and some people has talked about getting a redesigned wiring harness to correct the issue from Toyota, but no recall. This is a serious defect in the SRS that should be covered by Toyota. A recall should be issued for this problem. This system should not just break down over a few years of life nor cost so much money to fix. The cost to fix the problem is more than what most people can afford.

I bought a Toyota Sienna 2006 certified used vehicle last Dec. 09, 2010. After driving for just less than 4 months I noticed that the SRS light started to blink while driving to work. I informed my dealer 4 days later through email. But the lights went off a day after before I came down to his place and had been working normally for about 7 months. Then the issue came back again, brought it down to South coast Toyota and was told that code: B0116 driver side airbag and wiring loom need to be replaced for $3426. Toyota was informed but said it was not covered by warranty. I am severely disappointed as the reason I bought a certified used car and pay the price was the assurance that I will not get a lemon. But I was wrong and Toyota's assurance on quality of certified used car is purely crap.

Sienna 6-cyl

  • 76,102 miles
The air bag warning light illuminated, and continued to flash. I took the van to the local Toyota dealership the next business day, as a faulty safety system was concerning. The service department handed me a $3,000 estimate to replace a faulty wiring harness and air bag assembly, along with the news that the "platinum" extended warranty I purchased would not cover the repair. It seemed odd for a critical safety system to fail while the vehicle is relatively young, so I checked online. One site alone showed 85 owners of 2006 Siennas with this same problem. From a reliability perspective, a critical safety system should last longer than this. This is especially true when repair of the system is prohibitively expensive. The items affected were a floor wire harness and side air bag assembly, part numbers 82161-08330 and 73920-AE031.
