2004 Mazda MPV Engine cooling Problems

“My radiator fan constantly runs intermittently but with increasing lengths of time, regardless of the weather (hot, cold.) the engine does not overheat. But the lights dim at night when the fan kicks in and creates a loud humming sound that is becoming more irritating. I read on the web that many earlier models of the Mazda had a recall for the fan control module up to 2003. My vehicle is not in the recall, but I noticed a lot of people on the web have models after the recall period and we all have the same problem as the recalled modules. …”

“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.”

“The engine coils have failed 4 times since we have owned the vehicle. Last night while traveling on the interstate in the rain, key words, in the rain it started again. I am sure at least one if not two coils went this time. Just had a coil and all the boots that are suppose to protect the coils and keep the moisture out replaced in february, 2012. It always happens when it rains. Mazda is well aware of the situation and has done nothing to fix this issue except to stop using this system and start making their cars differently. But what about the people who own the older models? …”

“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. …”

“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 ... …”
