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 that 2003 Mazda tribute has been idling at a high RPM. The contact took the vehicle to an exxon station and the vehicle was diagnosed as needing a new speed control cable. The contact researched, and found that there was a recall issued for the speed control. She took the vehicle to a Mazda dealer, and was told there was no recall, but they did not diagnose the cause of the problem. The contact stated that the high idling happened frequently, but not every time she started the car. It also happensed when she stopped at a light. There were no warnings signs or indicator lights present at the time of the failure.
