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... the car lost acceleration capacity and became very difficult to drive... I could have been in a serious accident. I am now concerned that this ignition coil problem may continue to re-occur in the future.

2004 Mazda MPV engine failure due to engine coils, one went out in may driving in the rain on the highway and another went out two months later also in the rain on the highway. Dealer said it is common. Well then there needs to be a recall. The vehicle only has about 50K miles on it.

Mazda MPV 2004 vehicle's engine hesitated when driving in rain at any speed. This began happening before mileage and date listed below. This is a safety hazard when particularly when it occurred while driving on the Washington metro beltway. An assistant service manager at, rosenthal Mazda arlington, 750 N. glebe road, arlington, va. ( 703/527-3000) advised that this problem was known to Mazda for the past five years and required air induction service every 12,000-15,000 miles. We never were warned of this problem or the need for the specific preventable maintenance by either the company or rosenthal Mazda. The repair cost $2000 and could have been avoided if Mazda had advised owners of the need for preventable maintenance (air intake manifold). I repeat that this is a safety issue, causing the driver to be distracted and the car to accelerate poorly, particularly when the engine is hesitating while driving at high speeds in congested traffic. Please contact Mazda and investigate and require them to send warnings and reimburse those who suffered monetary damage as a result of their lack of warning.

2004 Mazda MPV with 63K miles. Has broken down 5 times with same problem affecting one of two different coils. Engine light comes on. Van hesitates/shakes. No loss of life, but plenty of lost wages etc and Mazda rep not cooperative. $400 and average 3 days in shop each time to repair. Mechanic guessed problem before I even told him. States that they see this all the time with the MPV's.

The contact owns a 2004 Mazda MPV. Every time it rains, the engine misses and the check engine light illuminates. The contact took the vehicle to the mechanic and was informed that moisture enters the engine and fouls the cylinder when it rains. The failure causes the vehicle to run roughly and travel only at low speeds. The vehicle has not been taken to the Mazda dealer, but the manufacturer stated that there was no recall. The current and failure mileages were 80,000.

MPV 6-cyl

  • Automatic transmission
  • 4,000 miles
2004 Mazda MPV - transmission issues and engine coil failures. Transmission has shift shock, where the vehicle slams into the next gear at 20 mph. The shock sends the vehicle dangerously forward. Mazda had two service bulletins for this defect which included replacing sensors and switches. Mazda also supplied a diagram to instruct drivers to "wiggle" the gear selector between gears. None of this solved the problems. Engine coils were replaced three times at 24,000 miles, 32,000 miles, and 35,000 miles. This caused the vehicle to stop running correctly while driving.

MPV 6-cyl

  • Automatic transmission
  • 1,100 miles
2004 Mazda MPV purchased on Feb. 28, 2004. On Mar. 27, 2004, engine failed without warning lights. Fortunately, car was idle when engine failed. Only had 1,100 miles on vehicle. Manufacturer has not been cooperative in diagnosing the problem. Initial assessment by the dealer tech at star Mazda in glendale, ca was that connecting rod failed and engine seized. Dealer stated that Mazda's own tech people would have to take a look at the engine to diagnose problem. It has already been a week. Requested vehicle to be towed to 1000 oaks Mazda, where I purchased the vehicle. Mazda still not given approval for that towing. Still waiting
