Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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.”

NHTSA complaint #10490620, filed 2012-12, 26,000 miles

“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. …”

“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.”

“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. …”
