2004 Mazda MPV Problems

Engine -- Verified

Defective or worn out ignition coils can cause engine misfires and Check Engine Light illumination. If the problem is severe enough engine performance will suffer and the Check Engine light will flash on and off.

Engine -- Verified

If the engine cranks but won't start, the fault may be internal to the distributor. Diagnosis will show no spark and trouble codes for the crankshaft position sensor (CKP) or the camshaft position sensor (CMP). Our technicians recommend replacement of the complete distributor assembly if these conditions occur.

Exhaust & Emissions -- Verified

The PCV valve can crack open and create a vacuum leak and lean fuel mixture, which can result in surging and/or engine misfires.

Engine -- Verified

If a rumbling noise is heard from the engine, along with a possible loss in power, it may be caused by a collapsed hydraulic timing belt tensioner creating excessive cam backlash. Our technicians recommend replacing the timing belt and water pump at the same time, if they have not been recently replaced.

Body, Interior & Misc., July 22, 2004

RepairPal Expert Overview:

Some vehicles were produced with an airbag warning label intended for the Canadian market. The labels contain warnings in both English and French. As a result, the area of the English warning is only 16 square centimeters as opposed to the 30 square centimeters as required by Federal standards. Owners will be provided with correct airbag caution labels and installation instructions which were mailed on July 22, 2004. The Mazda recall number is 1804C.

Body, Interior & Misc., July 16, 2004

RepairPal Expert Overview:

The tire information label may show the maximum tire pressure of 32PSI when it should be 35PSI. As a result, the load ratio for the 205/65R15 94H and the 215/60R16 95H tires exceed the levels permitted. If the tire is operated in an under-inflated condition, the load carrying capacity of the vehicle may be compromised, increasing the risk of a crash. Owners will be provided with a corrected label they can apply to their vehicle, or they can have a dealer install the label if desired. The Mazda recall number is 2140F.

2004 Mazda MPV Reviews

somebody can help me? on my mpv-2002, the electronic system to open the side-back doors SOME TIMES WORKS AND SOME TIMES NOT, please if you know why, may you let me know?? thanks

I buy it for my wife in 2004, after 90,000 have to replace the coils, great van, high performance, good for family car.

This car is great. The weather in Puerto Rico is terrible for the cars however, I have no complaints at all in this sense for my MPV. Another thing is the A/C system. It is pretty difficult and costly try to change the in-cabin A/C filters. Besides that, everything else is great.

I have replaced the 4 coil packs and spark plugs on three separate ocassions, other than these times I have the van, handles well and have no complaints

Great car but the engine needs coils and the pcv elbow to be replaced. They are a bad design. Interior, engine, and outside are great though. Handles well and plenty of power. Would buy again
