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.

I was in a parking structure, stopped at a stop sign. I continued a few feet to my designated parking stall and when I turned the wheel the car accelerated at what felt and sounded like full throttle on it's own. The surge of the vehicle forced the car to crash into a concrete wall causing extensive damage to the vehicle and bodily injury to myself. The vehicle is only a few months old. This car has some very serious safety issues. Someone could have been killed. Now I am terrified to ever drive it again.
