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.

2003 Mazda Protege Owner Comments

problem #1

May 082007

Protege 4-cyl

  • Manual transmission
  • 61,000 miles


While driving normally to my home after work the car stalled at a stop light. )when restarted there was a loud clanking/hammering noise from the engine for about 15 seconds then the sound went away, the cell lit up and the engine started shaking. When checked for codes a misfire on cylinder -4 was found. (the spark plug on cylinder 4 had been smashed flat by a foreign object that caused the hammering noise, nothing was found inside the cylinder, using a magnet. The spark plug was replaced and the car worked as normal. Upon investigation on the internet I found recall 3005C for the vehicle that describes my problem and if not fixed can cause engine failure. When contacting Mazda customer assistance they said my VIN was not in range for this recall and that I would have to pay for any repairs because my car has 61000 miles and even though the emissions warranty is still active, the regular warranty is over.
