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.

This was something that was wrong with the car when I bought it and my mechanic fixed it for free, but explained to me that the price to fix this normally was around $600. In the gas tank filler there is a valve that releases air out of the tank. A bug crawled in there and caused the valve not to work. When the valve doesn't work, the car runs a code, preventing it from being inspected. My mechanic had to drop the entire fuel system, empty it and run a smoke machine on it. Find out where the problem was, clean it out/replace the part. Return the fuel system to the bottom of the car.
