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.

At times when the driver quickly pulls out his shoulder belt the belt doubles over itself inside the guide on the door post behind and to the left of the driver's shoulder. If the driver continues to pull the belt the amount of overlap increases causing the belt to jam very tighly inside the belt guide. When this happens it is almost impossible to undo the doubled over belt (without damaging the belt) unless the trim panel and mechanism that attaches the belt guide to the car frame is removed. The shoulder/seat belt cannot be used when the belt is doubled over and jammed tightly inside the guide since the belt length cannot be adjusted. As such, when this fault occurs, the driver would be unbelted when operating the vehicle.

Driver seat belt fails to retract as the strap gets caught in the opening where it retracts. It did this on rare occasion under warranty but now does it constantly. There fore the seat belt is very loose and does not restrain the occupant. The rear belts were recalled for this type of defect and were working fine at the time of the recall. This problem has been ignored by the dealer under warranty and now they simply work it free when we bring it in, despite us telling them that it recurs daily.

The driver side seat belt sometimes fails to retract. When I pulled the belt out, it stayed out and would not retract. I inspected the area and found no interference. This happened on a sat. I drove the vehicle sat. And sun with a faulty belt. I called the dealers service dept. Told them the problem but couldn't get in for a week. In the meantime, the belt began to work again. The dealer said"bring it back when it doesn't work." I have a phobia not knowing when the seat belt will fail again. The vehicle is a 2004 Toyota Sienna. I purchased it new from the same dealer. Carmax in kenosha wi. I sent this same E mail to Toyota.

: the contact stated the front passenger side seat belt retractor locks up while in use. The seat belt must be released, and then put back on. The dealership determined this was a safety feature for child safety seats. The dealership stated it was illegal to replace the front seat belt assembly.
