I was in an accident where a majority of my front end was completely damaged. In fact, the bumper was completely taken off with significant other damage which I have pictures off. Neither airbag deployed. Fortunately I was ok and did not sustain any injuries. I am just surprised by the size of the impact that the airbags did not deploy.

Dash board cracked over glove box, then another crack appeared on the left side near the side window defrost vent. Wonder if it would affect air bag deployment?

Airbag warning light came on without apparent cause. We took it in to Toyota dealer, they said they replaced the passenger side airbag harness, but could not complete repair, airbag warning light still on. Toyota still waiting for another plug to repair 2 months later. Very serious issue as they said airbags will not work properly.

Airbag indicator warning light flashes continuously. Jiggled wires under front passenger seat a year ago, and the warning light quit flashing for a couple months. But then it started flashing again about six months ago. A warranty enhancement notification - ztx was received from Toyota a few days ago. Local dealer said that diagnosis would take two hours & cost $130. Read on the internet to try disconnecting the yellow wire (airbag sensor) under the front passenger seat and wait 15 seconds. Tried that and the flashing light has gone off again. This yellow connector pin and wiring should be fully replaced by Toyota under a full recall so that this doesn't become a recurring, regular issue for Sienna owners.

Air bag light started blinking when car started and stayed blinking. Brought in to dealer and comments were "open in side. Squib rh circuit" and "needs pass. Side front seat airbag" for $865. Same issue seems true for 2007 Siennas online. Light stopped blinking and has not recurred.

The passenger airbag control is intermittent, when a passenger is seated in the passenger front seat, the airbag many times is turned off. The vehicle has been taken to Toyota 2X for this problems as they point to seat belt latch, the last time after 2 weeks of the system not working, it starting working properly again. It worked for a month correctly and since started working again. This has been going on for over a year now not knowing if the passenger airbag will work in a crash. Toyota claims the airbag is connected to the latch of a seatbelt which was proven false on 2008 and 2012 models, they do not know how there system actually works, so how can they be relied on fixing it or knowing if there is a problem.

Flashing air bag indicator light, 4 tsb's have been issued for this problem with a replacement part. The tsb's are E1001-08, tsb 0069-12, tsb 0162-10, and tsb 0252-08. This is a major safety problem that Toyota is refusing to recall and correct. The NHTSA needs to make a mandatory recall for defective Toyota Sienna airbag wiring. Toyota dealership is demanding $50 to read code and average repair cost of more than $1000 dollars. This vehicle has never been in an accident of any kind. There is no reason that the airbags should have a defective condition so soon. There is obviously a manufacturing problem with the system which is why Toyota redesigned the part. Toyota cannot be allowed to charge customers $1000's of dollars to replace this essential safety equipment.

Could not stop after my ABS brakes locked up then were soft/absent, drove up on the center median, got back on the road attempting to go around the car infront on the right side couldn't due to other traffic then went back to the left got back up on the median. My passenger side front bumper corner went under the other driver's driver's side rear bumper corner lifting her car up into the air causing it to fall on top of the passenger side of my hood and front right fender crushing them, resulting in over 10000 dollars damage. No one was seriously hurt and neither car's airbags deployed.

On day of the accident, it was snowing and road conditions were icy and slippery. As vehicle was going around the bend, driver noticed cars were stopped at a signal. Driver could not stop vehicle in time to avoid a crash since ABS brakes locked all the wheels and the car was sliding and so driver swerved to avoid crashing into other cars and hit a tree head-on. Vehicle sustained front-end damage. Air bags did not deploy.

Was T-boned by someone who failed to yield on green. He was given a ticket. I was through the intersection going 34.8 miles/hour at the triggering event. Has Toyota do inspection on car and "chip". it only registered a "front event". repair costs are 12K, this included replacing both driver side doors"???? why did the airbags not deploy or better yet why was there not even a side event registered when he clearly hit me in the side?" suffered a concussion and neck back injuries. Had my 6 and 2 year old in the back in car seats.
