general problems of the 2004 Mazda MPV

2004 Mazda Mpv. Consumer states that while driving speeds of 70 mph the vehicle just lost all acceleration dropping to below 5 mph. She also states that the vehicle just shut off. The mechanics were unable to find a problem.

My 2004 Mazda Mpv suffered the same problem as many other consumers. On two different occasions I had to replace all of the coils and plugs on my vehicle. The first instance was just after the warranty expired and involved one of the rear coils but the said I should replace all three rear coils. The second incident occurred two months later to the front coil and I replaced all of those - total cost $900. I complained to Mazda but they wouldn't do anything for me. This should be recalled and owners compensated.

Mazda 2004 Mpv with just under 68,000 miles has 3 fuel injectors(cel) replaced by local mechanic- 2 weeks later jerky misfires with cel required #5 coil replaced by dealership, less than a month later #4 coil replaced by local mechanic in town we were vacationing in-no cel, now same jerky misfires starting again a month after last replacement. Recent forum entries seem to indicate a growing problem of this type for 2004 Mpv. Except for towing charges, expensive repairs, and inconvenience- no injuries.

Vehicle was lurching, no warning light was on. It took a while to figure out the rear coil was bad. We spent $1200 getting a tune up and that didn't fix the problem took a while to figure it out. Also, the transmission failed on this vehicle completely at 55 thousand miles. We had taken it in 3 times before it failed and they said nothing was wrong with it.

We have 2004 Mazda Mpv which we bought new. While it was still under warranty, we had to have coils replaced. We thought it was odd that we would be having to replace coils on such a new vehicle. After investigation, we found that this is a common occurrence with the year Mpv we have. Apparently there is a design flaw which allows moisture to get to the coils, causing them to short out. We mentioned this to fitzgerald Mazda in annapolis, MD where we were having it serviced. They admitted this was a problem but basically thought we should be happy that it was still under warranty. . Even though it was probably going to be an ongoing problem long after the warranty ran out. Since the warranty ran out, we have had to have coils replaced 2 more times at our own expense and are waiting to have yet another coil replaced as I am writing this complaint. Each time we have to have a coiled replaced, it is very costly due to the fact that the design of the vehicle makes them very difficult to get to. Once we had to have it done while we were traveling on vacation in florida. . This was done at the Mazda dealership in gainesville, florida. Then another time we had a coil replaced by a mechanic in owings, maryland. That mechanic did extensive research for us and came to the same conclusion. . This is a problem with moisture getting to the coils and will happen again and again throughout the life of the vehicle. We are now delaying another vacation. . Paying out of pocket to have yet another coil replaced. We want Mazda to stand my their product. There should be a recall and they should be required to correct the problem at their expense. We have spent close to $2,000. 00 now. The worst part is, it is only a matter of time before another coil goes out. Please help!.

The contact owns a 2004 Mazda Mpv. While driving at speeds of 30 mph, the vehicle began hesitating as if it were attempting to stall. The vehicle was taken to the dealer where they replaced the electrical coil to the cylinder. The repairs were performed under factory warranty. The failure recurred within a year and the vehicle was taken to an independent mechanic. The mechanic placed insulating materials around the coil to prevent moisture from entering the coil. The mechanic advised when moisture would enter the electrical coils; it would cause a shortage contributing to the failure. In addition, when the engine was shut off, the cooling fan would continue operating. The failure persisted. There were no recalls for the failure. The failure mileage was 23,000 and the current mileage was 100,000.
