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.

One of the metal brake lines between the master cylinder and the ABS modulator valve ruptured during a stop due to corrosion. All brake lines in the vehicle have similar levels of corrosion near the area the aforementioned line ruptured, and at various other locations on the vehicle. The transmission cooler lines had failed approximately 18 months previously due to corrosion. The corrosion and rust on many components beneath the vehicle and in the engine compartment is becoming rather concerning.
