2003 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.

Engine -- Verified

The cooling fan module can fail causing the fan to either run constantly, or not operate at all. If the fan runs continuously, the engine may not warm up properly, and if the fan does not run, the engine may overheat. Mazda has a voluntary recall on model years 2002-2003 to address this concern. Please click here to find a Mazda dealer near you.

Engine -- Verified

A loud ticking noise (hydraulic valve lifter noise) may be heard from the top of the engine, particularly when the engine is still cold. The noise may occur more frequently on higher mileage vehicles; Hydraulic valve lash adjusters may need to be replaced to correct this issue. Following the maintenance schedule for oil changes will also help prevent a recurrence of the noise.

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.

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.

Electrical & Lights, July 14, 2003

RepairPal Expert Overview:

The heat generated by a fog light bulb can cause the socket holder to be pushed rearward in the light casing. This, in combination with the normal vibration during vehicle operation, can cause the bulb holder to separate from the light casing. Should this occur, the bulb socket and harness can drop inside the bumper and possibly result in the bumper being burned by the hot bulb. Dealers will install a spring to prevent the socket holder from separating from the lamp case. The Mazda recall number is 1103F.

2003 Mazda MPV Reviews

I like to drive this car, been driving it for about 5 years. But it has some serious (idiotic) design problems:
-Transmission had to be completely replaced at 100,000Km. -Alternator is BELOW the car, I think front axle needs to be removed in order to remove alternator, sludge gets there easy.
-Oxygen sensors 4x, chronic problem - one of them is extremely difficult to replace. Generating engine trouble warnings on dashboard.
-Rear heater - pipes under car, originally made of steel, will rust out in few years - cause cooling liquid leak > engine overheating - there is no indication other then temperature gauge needle, easy to miss.
-Spare tire attached to bottom of the car by little crane, will rust out in few years, becoming unusable.
-Front light-left - bulb is very difficult to replace. Battery needs to be removed first etc
-Steering, vibration from road is felt - feels like unbalanced tires, but body is not vibrating only steering wheel.
Good part - I still like the drive (except the steering vibrations), never have had problems with engine, AC, electrical, electronics, brakes.

We have owned this car since new, Have had some problems with plug wires and coils being replaced (2) and only 90k, but over all it has been a good van and would buy Mazda again
