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.

Power steering leaks; no warning notice ( no lights came one in the vehicle on indicating that the fluid was low. The people who towed the vehicle said if she had lost control she would not had been able to control the vehicle because the ps would have gone out on the vehcile. Had it in 8 or 9 times for the air conditioning not working correctly.
