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.

2004 Mazda MPV Owner Comments

problem #2

MPV LX 3.0L V6

  • Automatic transmission
  • 140,000 miles


My 2004 Mazda MPV with 140,000 miles on it has had the coil packs replaced for the 3rd time since I have owned it. I feel that it is a recurring issue. $800 + each time. The spark plugs are located 3 upfront(easy access) and 3 in back, which require removing top part of the engine to get to them. Each time, the check engine light comes on, misfires are reported and all six spark plugs are replaced with coil packs. From what I have read on other sites, this is also a known issue with Mazda MPV engines.

I had the van for 2 months and the Coil in cylinder number 3 went in the motor. It caused the van to jerk when accelerating and was quite and inconvenience, Also the thing has 4 O/2 sensors and they don't last very long, i've already replaced 2 of them because they break constantly.
