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 2005 Prius we own will not start at scattered times (after driving for some time and then stopping and turning the engine off). The screen on the dashboard panel lights up partially and not always the same on repeated tries. Other strange electrical events occur such as the automatic windows going down when the car is turned off after trying to start it unsuccessfully. The car will start at some time - up to 20 minutes after letting car sit. These events are similar to those that occurred in days prior to the March 29,2005 when the car stalled at 45 mph on a highway in the outer banks of North carolinas and was serviced with what became a recall later for Prius's. the most recent problems occurred on March 17th and May 1, 2006. We have taken the car to lustine Toyota in woodbridge, va and they have tested the car and say that everything checks out ok and their is no service bulletin from Toyota. They are looking at the car again today. We are concerned that the problem could continue and place us in a dangerous situation either from another stalling incident or leaving us in a dangerous place with a car that will not start.

1) I received a notice from Toyota about a navigation system software update. The car was brought to the dealership where the update was performed. 2)after leaving the dealership, in less than 2 miles, the car engine stalled as I was depressing the accelerator. I pulled to the side of the road. 3) my car has the smartkey system, so at the time, the key was not inserted. After inserting the key, I was able to restart the car. This occurred again afew days later, and the car was restarted only after inserting the kay.
