Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Cracks started appearing on the dashboard around where the passenger airbag would deploy. I'm concerned that shards of plastic may be ejected toward occupants and injure them if the airbag deploys.

Due to a failure in the moonroof system in the vehicle (rubber seal and two drains on either side), rain water seeped into the air bag system resulting in mold-build up and serious damange to the vehicle and possible malfunction of the air bags and breathing of dangerous mold/fungi. All the passengers in the vehicle got nauseous in 1-hour journey and the future consequence of such fungi build up and potential failure of the air-bag could be life threatening.

The Sienna was impacted from the rear when stopped at a stop light. The rear, moving vehicle was traveling at 30-40 mph. The Toyota Sienna then had impact at the front into another vehicle. This three car pile up resulted in the Sienna being a total loss/not repairable. The air bags for the first and third vehicles deployed on impact, and no injuries in those vehicles were reported. The air bags in the Sienna did not deploy, and resulted in the driver receiving a severe neck sprain and lower back pain. Driver was taken by ambulance to hospital and released with work restrictions for three days.

I have a 2004 Sienna xle limited that has always been garage kept and very well taken care of. The dash on the passenger side above the airbag has been cracking for sometime now and what once started as a small crack, is now a spiderweb of cracks that extends over the entire passenger side of the dash. When searching on the internet for a used dash I came across the following thread: and discovered this is not an isolated incident, that it has, in fact, occurred in many 04 Sienna's. I, along with many others feel this is a safety hazard due to what would happen to the already cracked dash if the airbag were to deploy. I have called Toyota and registered a complaint and was assigned case #: 1207232487. I have also emailed Toyota with a complaint as well. Because of the number of incidents, I believe Toyota should issue a recall. I need a new dash, and because it's obviously a manufacturer's defect.

Dashboard defect interference with airbag deployment - due to manufacturer defect the dashboard has many long cracks that extend from the A/C vents and glove box across sections of the dash, including around the airbag. I am fearful that in the event of a crash the airbag would not deploy as designed, due to the defective dashboard. As of yet there has been no recall or manufacturer amends to this problem. It is a serious safety concern to me due to interference with the proper functioning of the airbag.

Cracks along the entire dashboard and airbag areas of the front dash. Concern about proper airbag deployment or failure and lack of structural integrity of the dash along with steering control during a vehicle crash. Dash failure and debris from dash may affect the steering control if dash debris is lodged against steering area. Noticed dash cracks at about 60K miles and the cracks continue to grow with each use of vehicle. Currently vehicle has 79K miles. Dealer/manufacturer did not want to fix or replace the dash citing out of warranty issue. However, this issue is on all 04 and up Toyota Sienna's and possibly more vehicles with this type of dashboard material.

In my 2004 Toyota Sienna xle limited AWD, the upper dashboard(by the windshield & front airbags is cracking. I am highly concerned that these cracks will interfere with proper deployment of the front airbags in an accident situation. Also the upper dashboard may break apart in an accident situation and become airborne causing further injury to vehicle passengers. I have contacted Toyota and was told it was only covered for 36,000 miles or 3 years despite the fact it can pose a safety issue. In researching the internet, I found other 2004-2007 Toyota & Lexus owners are having the same issue with the cracked dashboard. Here is a link to one such discussion:

Dash is cracking and it has been parked in the garage each night the entire time since we purchased it new. No care or concern from Toyota about the safety of the airbags ability to perform with the dash in this condition. Very displeased with the lack of concern for the welfare of my family and all passengers.

I have a 2004 Toyota Sienna with 92,000 miles (past warranty) that has a flashing dash light that is supposed to indicate that the air bag system isn't working properly. Toyota has repaired it twice. The indicator light is flashing again, and I don't know if there is a true malfunction with the air bags or not. The dealer and Toyota said they would not repair the problem again. I thought that in Maine (nationally?) such inoperable safety equipment must be repaired free of charge. Am I correct? the problem is a severe safety issue;the air bags may not deploy in an accident -- the flashing fault indicator may not be correct, but my dealer can't assure me of that. I am told that resolving the issue (again!) could cost up to $2,000.

I had slowed my car to allow a group to pass and was making a left hand turn into a parking spot. My car lurched forward and sped forward nearly striking a group of teenagers. I plowed through three cement pillars and a flower pot and finally came to rest. My engine was revving and my foot was on the brake. Updated 12/02/09 updated 12/03/09 the consumer also stated the air bags did not deploy. Updated 12/03/09
