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.

2005 Mazda MPV Owner Comments

problem #4

MPV 6-cyl

  • 70,000 miles


Vehicle is manifesting rough idle when turned-on with check engine light on and/or flashing. Engine and vehicle is jerking intermittently when driving at any speed. The vehicle was repaired last year through dealership but this kept happening for the third time within a year. Dealership indicated engine misfiring due to burnt engine coil. If this keeps happening even after being repaired for several times within a year, something is terribly wrong with Mazda engineering. This is a tremendous safety issue specially for my family and other motorists, and this type of vehicle should be subject for recall.

The idle air control valve on these vans is seriously flawed and is prone to failure which stalls the engine and puts occupants in peril at high rates of speed without power braking or steering. Once stalled, the engine can often fail to restart, leaving the driver unprepared and paralyzed to react. Background - approximately six months after purchasing our van used (2-3 yrs old / 30K miles), we began to experience significant issues with the vehicle stalling randomly after 6 months of owning. Unfortunately, the engine stalling was not a result of not maintaining an idle well on a regular basis. It was random and often followed by the engine running extremely rough, once the driver was able to restart (but then would go away completely undetected). I cannot stress how unpredictable the engine was over the year we experienced this intermittent stalling. Every 1-3 weeks it would stall and sometimes we'd be stranded 1-30 minutes before starting and running normally (no check engine light after engine sat and restarted. Light would come on when problems started and would cycle off once engine ran and computer checked sensors. Why the contact to the NHTSA? real issue I have with here is that the van would randomly fail to idle and stall the motor when at freeway speeds over the year (6/2009 - 6/2010) this went unidentified. As a primary means of transportation in our household for four children (as most vans are), my wife refused to drive the vehicle starting in beginning of 2010 because of her experiences and subsequent fears after many close calls in which she couldn't steer or brake in a safe or reliable manner. The driver must shift to neutral (while at 70+ mph), and attempt to turn the engine over, to gain control again. Take action on this as it is far too common and dangerous to ignore. Mazda must be held accountable for the safe operation of these vehicles.

I was waiting to make a left turn into my drive way, waiting to clear oncoming traffic. When the oncoming traffic was cleared, I found a gap before the next car comes my way and I decided it was safe to make a left turn. I turned the wheels of my Mazda MPV, but car went stalled, it would not move. I had to stop the engine, and restart the car. I searched the internet and many people have the same issue due to clogged up iac valve. This is a very big risk to the safety of the passengers and should be a recall.

I was driving at a very low speed in heavy traffic. Lane next to me started moving, so I decided to change lane, find a empty space between 2 vehicles and decided to make a turn. My Mazda stalled, and did not move. I had to put it back to "park", stop the car, and restart, after that it ran ok. All this was on a freeway with moving traffic in the middle of the lane, when my wheels were turned and partially on the next lane and car body was standing still. I searched on the internet and it has happened to many people, due to iac valve getting clogged up. This should be a safety recall.
