Tl* the contact owns a 2003 mazda mpv. The contact stated that the engine was misfiring due to a coil spring fracture that randomly occurred several times. The contact stated that the previous owner had to replace four coil springs that prematurely fractured. The contact later owned the vehicle in mid april 2015 and also had to replace two coil springs that fractured prematurely. The dealer also replaced a gasket cover. In addition, the dealer diagnosed that the catalytic converter needed to be replaced due to the failure. The manufacturer was notified of the failure and provided no permanent solution. Tha manufacturer indicated that the catalytic converter was on back order so the contact was unable to determine when the vehicle would be repaired. The failure mileage was not available.

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.

We own a 2005 mazda mpv. Four years after purchasing, the vehicle started to shake continuously and the check engine light turned on. Also when going uphill it almost can' t make it to the top. After taking it to the mechanic it turns out the engine was misfiring due a bad ignition coil. We replaced the coil. A few weeks later it started doing it again. This time we changed the six ignition coils. A few weeks later it started again with the same problem but not as bad as it was before. We kept using the vehicle like that, for a short period of time. Now the problem was worse, the vehicle started shaking and it started holding back. We took it to the mechanic again. He changed one ignition coil. It worked for a few days. Then it started shaking again. The mechanic change another one, the six spark plugs and one injector. It kept with the same problem. So the mechanic suggested to change the six ignition coils, and we did. The next day the check engine turned on again. I really don't know what is wrong and spend a great amount of money on trying to get the vehicle fixed. I have changed the ignition coils and still the vehicle is not working properly. After research online, we found out we are not the only ones dealing with this problem.

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.

2003 mazda mpv. 70,276 miles. 3/8/11 - started running rough. Two rear coils bad; dealer repaired all three rear coils because (according to dealer) once one goes, they all go. ($855.01) one week later - 3/16/11, rough idle and odor of gasoline. Check engine light goes on. 70,339 miles. Dealer replaced all 3 front coils. ($463.76) I am told this is a *common problem* with mpvs. Dealer told me he has seen many of them coming in, and it was a good thing I was having it taken care of promptly. If I did not, the catalytic converter goes bad as a result...cost of replacement of the cc: $1,000. Note: I overheard the service manager on the phone telling a customer the spark plug boot goes bad first, and causes some kind of electrical problem that damages the coils.

We own a 2005 mazda mpv. Two years after purchasing the vehicle it started to shake and jerk as if it wanted to turn off, after taking it to the dealership it turns out the engine was misfiring due an ignition coil giving out. Nine months later it happens again. This time they replaced all 6 six ignition coils. Two years after replacing all six coils it happens again. This time they replaced the #3 coil. While at the dealership the service lady told us that this is a consistent problem with this vehicle and that we would have this problem with the coils for as long as we own the van. All three times that this has happened the car shakes and acts as if the engine wants to shut off. After vigorous research online we found out that we are not the only ones dealing with this problem. After complaining to mazda via email all they had to say was since the car was under warranty and all the coils where fix that they would not be able to help us in the future once our extended warranty runs out.

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.
