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 ignition coils on my 2003 Mazda MPV fails while I was driving. My van only has 27,000 miles on it. When I did more research, I found this is a very common problem for MPV. This needs to be a recall!

At speeds of 25 - 35 miles per hour, our 2003 Mazda MPV LX stalled for no apparent reason in traffic. All control of the vehicle was lost when it stalled, luckily, we were traveling at speeds and in a lane that no accident occurred, however, it was extremely dangerous. We had the vehicle serviced at a dealer local to where we were vacationing. The dealership, holman Mazda in egg harbor township, NJ, replaced an air bypass valve, which they stated was the reason for stalling at approximately 2500 RPM. When asked if this was a normal failure, the dealer did not believe so.

While driving at any speed, the gears in the vehicle seem to be slipping. The gears didn't change at the proper intervals. There were times when the consumer would be at a stop light and the vehicle would lurch forward, as if struck from behind. The check engine light came on and stayed on. The vehicle was taken to the dealer, who reprogrammed the PCM module in the transmission. The reprogramming did not stop the engine from slipping, but it did cause the check engine light to go out. The vehicle has been in the shop for the engine slipping three times, and the problem still persists. The manufacturer has been informed of the problem.
