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.

Car has trouble starting and check engine light comes on intermittently. July 2007 took car in with 'hard start" problem. They found resonator assembly needed replacing. That repair was done on August 3, 2007. Car ran for approx. 2 months and we took it back in October with the check engine light on and the same "hard start" problem. They replaced the starter October 18, 2007 and stated it was arcing to high. Took car back October 21, 2007 with the same problem. October 26, 2007 the ECU computer was replaced. Took car back to shop October 29, 2007 with the same "hard start" problem. Moved the car to another dealership November 7, 2007 as no one was working on the car. This was suggested by the corporation. A repair was done on the car. December 13, 2007 took car back to this dealership with the same "hard start" problem. They checked the code and reset the check engine light. December 18, 2007 returned to the dealership with the same problem. They replaced the engine wiring harness. January 25, 2008 the car is having the same "hard start" problem and is sitting in the yard.
