Ignition Coils Failure problems of the 2004 Mazda MPV

Ignition coils retain moisture and cause cylinders to misfire. This causes vehicles to stall or lose power -- usually when raining. In our case, this has happened repeatedly on the interstate during rain. We early caused an accidents by our inability to get out of traffic with our suddenly-slowed vehicle. Replacement of a single coils cost us over $200. There are six ignition coils (over $1000). Many internet forums indicate that this problem is systemic in this make/model. We understand that the manufacturer redesigned the coil for subsequent models. They obviously recognized the flaw.

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.

Bought the 2004 Mazda Mpv ES in 2005. Currently it has about 64,000 km (40k miles). Problem: recently 4 ignition coils malfunctioned . . Had 3 replaced right after warranty had expired. Apparently, this is not an uncommon problem for this 2004 model. Watch out!.

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??.

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 ã‚ 31,770mi - #4 coil replaced. Transmission range sensor replaced also 12/05/06 ã‚ 33,229mi - #4 coil replaced again 1/08/07 ã‚ 34,708mi - #6 coil replaced. Today as I was driving, the same symptoms ã‚ steering wheel vibration, bucking, lurching ã‚ 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.
