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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.

While driving on the freeway the glass sunroof/moonroof of my 2004 Toyota Sienna xle shattered. From the pattern of the glass breakage it looks like the glass broke due to interior cabin pressure. This is actually the second time this has occurred with this vehicle. We had been on the road for about 4 hours, we did not hit a pothole and we had not gone under an overpass. We heard a loud boom and then the sound of broken glass on the roof and dropping onto the sunshade. Luckily the sunshade was closed or my wife and kids would have been showered with broken glass. I called my insurance company and the glass was replaced by the dealer only part.
