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.

First the RPM gauge stops working properly, then the temp and oil pressure gauge do the same. After all that you get a check gauges light and a annoying dinging noise that wont go away.

While driving down the road, my car shut off and I almost drove off the road because all of the lights shut off and I lost control of my power steering and brakes.
