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.

problem #1

Sienna 6-cyl

  • Automatic transmission

There is a sour smell (sulfur-like) coming from under the car. Dealer told us it is a problem with the catalytic converter, but as of 1/25/04, they don't have a fix for it. Said Toyota is aware of the problem. I would like to know what the problem is and when it will be fixed. This not only is polluting the air, but also could pose as a health hazard for those in and around the car.
