With our mazda 2004 mpv, we have had four separate incidents in 2 1/4 years from mar 2008 through june 2010 where the check engine light has come on to indicate an engine problem. In each incident, the vehicle runs very rough and very slow. Each incident resulted in us taking the vehicle to the mazda dealership where some or all of the ignition coils were replaced. For some of the incidents, the vehicle was out of warranty but in each incident all or some of the costs were covered by mazda. In 2 of the incidents, we were out of town and it was dark. In another incident, we were leaving town, and the other, we were in town. Now, we will not take the vehicle out of town for fear of completely breaking down at night or in unsafe conditions. On the internet, I find very many similar incidents for the mazda mpv.

At approx. 50,000 miles my 2004 mazda mpv's 'check engine light' went on. When I brought the car in for service I was told an ignition coil had to be replaced. At approx. 60,000 miles, the same thing happened ... The car's check engine light ' came on and, again, an ignition coil had to be replaced. I have since learned from web postings that this ignition coil problem may be a fairly common repair on 2004 mazda mini-vans and I'm wondering if this is a design defect that should be addressed through a recall and repair by mazda. Were I on a highway when the light came on ... The car lost acceleration capacity and became very difficult to drive ... I could have been in a serious accident. I am now concerned that this ignition coil problem may continue to re-occur in the future.

2004 mazda mpv: I have had to replace all 6 ignition coils in my van - the van would shake and seem to be stalling and the engine light would come on. This started in july 2007 and continued so far through jan 2010 (when 4 coils and all my spark plugs needed to be replaced at once !). I have also had the car in during oct 2008 because the fan would continue running for several minutes after the van was shut off. My dealer told me this is a "ford" issue. When will mazda be required to pay for all these expensive repairs??

Like many other mazda mpv owners, I've experienced problems with the vehicle's ignition coils. In august 2008, the vehicle was riding very rough and hesitating on the highway. The diagnostics for the check engine light showed that one of the ignition coils had misfired. I had the coil replaced and, at the recommendation of the dealership, replaced the spark plugs. At that time, my vehicle with approximately 35,000 miles on it, was out of warranty. I paid $476 for the repair but was ultimately reimbursed by mazda on a customer goodwill basis. One year later, in august 2009, the vehicle again began riding rough and hesitating. When the check engine light came on, I brought the vehicle to the dealership. Based on the earlier experience, I suspected an ignition coil as the culprit. My suspicions were realized. The dealership found that cylinder #5 had misfired and that several other coils were weak. The dealer indicated that the other coils were likely to go and recommended that all of them be replaced. I had the work done at a cost of $960. The vehicle at this point had only 46,000 miles on it. Both repairing dealerships mentioned that this is a common problem with mpvs. From my research, I can see that is a significant problem for 2002-2006 mpv's. Entire message boards are dedicated to this mazda mpv ignition coil defect. Most believe that there's a design flaw that prevents the coils from dispersing moisture properly, which over time leads the cylinders to misfire. It seems to me that mazda should have voluntarily recalled the vehicle due to this issue. Having previously made a customer accommodation on the earlier repair, mazda has refused to reimburse me for the costs of this latest repair. It's unfortunate that mazda has chosen to deal with the problem on a customer-by-customer basis, rather than having voluntarily recalled the vehicle in order to address this very common problem.

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.

Tl*the contact owns a 2004 mazda mpv. Every time it rains, the engine misses and the check engine light illuminates. The contact took the vehicle to the mechanic and was informed that moisture enters the engine and fouls the cylinder when it rains. The failure causes the vehicle to run roughly and travel only at low speeds. The vehicle has not been taken to the mazda dealer, but the manufacturer stated that there was no recall. The current and failure mileages were 80,000.

I purchased a 2004 mpv arch 28, 2005. To date, I have had this van in for warranty service to replace ignition coils three times: 10/31/06 '' 31,770mi - #4 coil replaced. Transmission range sensor replaced also 12/05/06 '' 33,229mi - #4 coil replaced again 1/08/07 '' 34,708mi - #6 coil replaced. Today as I was driving, the same symptoms '' steering wheel vibration, bucking, lurching '' occurred as before when the other coils failed. The cel came on, I checked for the code and I discovered that the #5 coil has failed. Now this will be the fourth service for the same problem. There has been no effort on the part of country mazda to find the source of the coil failure. Replacing the parts obviously is not solving the problem.

2004 mazda mpv. Engine went out without warning while cruising at 65 MPH on the highway. Check engine light on. The car had only 3000 miles on it at that time. Got towed by mazda roadside assistance to the closest dealer, who had no time to work on it for more than a week (!). Therefore the car was towed at mazda's expense to the dealership I had bought it from. There they did not find anything wrong with it and therefore concluded that the ecu must be faulty. A new ecu was installed and the problem has so far not recurred. The car now has about 14000 miles on it.
