Known Problems

Rattling noises from the front suspension while driving over rough roads can be caused by defective front sway bar bushings. Replacing the bushings with the updated design is a common repair.

Mazda issued an emissions recall due to a problem with the Swirl Shutter Valve; this would cause the Check Engine light to illuminate.

Internal failure of the ignition switch may create a condition where the key reminder continues to chime even though the key is removed. In addition, the doors cannot be locked with the keyless entry system. Replacing the ignition switch with an updated switch is the typical repair.

If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.

An electrically shorted air flow sensor can cause a crank-no start condition. Diagnosis may show that ignition spark is normal, and there are no trouble codes stored.

The "Bypass Air Control Valve" can fail causing a low engine idle and possibly stalling.

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.

Misfires under load (acceleration) can be caused by the valve cover gaskets leaking oil into the spark plug wells shorting the spark plugs to the cylinder head. New spark plug wires will be needed and the valve cover needs to be resealed.

A dirty, or contaminated mass airflow (MAF) sensor can cause the engine to run poorly. There may be a Check Engine Light with trouble codes relating to the MAF sensor, P0102 and/or P0103. In some cases, carefully cleaning the sensor element will fix the problem, but replacement may be required.

A knocking sound heard from the front or rear suspension while driving over rough roads may be caused by the sway bar linkages. The linkages should be inspected for tightness and condition; there are redesigned linkages if replacement is necessary.

If the climate control's heat/cold knob is not adjusting to the desired temperature, a new climate control unit may be needed.

A Loose rear stabilizer bar link can cause a rattling noise from the rear suspension while driving on rough roads. Our technicians tell us if the rear stabilizer bar and links are not found to be loose, there are updated sway bar bushings available which should correct this problem.

Some models may have a problem with stalling under light acceleration. Updated software for the powertrain control module (PCM) is available which may help with this concern.
