Example complaints

Engine cooling: “The ignition coils in my car are going bad. One right after the other. Mazda told me that the heat of the engine (miller cycle) is causing this. I think the engine was poorly designed. There are 6 coils & I have replaced 3 so far, 1 in 12/04 & 2 in 4/06 along with all the plugs. This problem started in 2002 when cylinder #4 was misfiring. Mazda replaced the spark plug. The coil in cylinder #4 was the first coil to go bad. The original plugs were champion. I was told these were the wrong plugs especially for this type of high performance engine. …”

NHTSA complaint #10158185, filed 2006-05, 18 miles

Electrical system: “Before our factory warranty was up the dealership fixed our catalytic converter 3 times. After our extended warranty was up we in the last 6 months had to fix both upper camber arms, driver side axel, tire rod ends on both sides, driver side wheel bearings, and now just yesterday we broke down. The belt pulley tensioner went. The Mazda parts co. Had told me that they had this part in stock about 10 minutes ago but sold it. This is a $300.00 part and the maintnence is about $500.00 to have them fix it. I don't understand why there hasn't been any recalls on this vehicle. …”

Equipment: “We own a 2000 Mazda Millenia that stalls at about 50 MPH and has had this problem since we bought the car. We have taken the car in for servicing numerous times, but have not been able to get this fixed. The car has several other problems such as: keyless entry does not work, heated seats do not work, air conditioner does not work; however, none of these pose a safety problem like the stalling. The engine light remains on even after numerous attempts by the dealership service department to repair this problem.”

NHTSA complaint #10021437, filed 2003-06, 500 miles

Fuel system: “I was pulling into a parking spot in front of the grocery store, when the car started to rev up the engine and drive at speed hitting a supporting column in front of the store. The car jumped the cement block and front was on sidewalk. Passenger side front fender, wheel, smashed. Accelerator stuck.”
