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.

The contact stated while driving, the reduce power engine and oil pressure low, check engine ights illuminated. The vehicle stopped, although, the enginewas still running. The dealership was unable to diagnose a problem, but replaced the tank gasket, gas pedal, and computer chip. This caused the contact to rear end another vehicle.
