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

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.

The engine may develop a ticking noise from the front of the engine due to a worn timing chain. Our technicians tell us that replacing the timing chain and related component will generally correct this issue.

Various electrical issues may develop related to the body control module (BCM). There have been reports of water damage to the BCM caused by clogged or damaged sunroof drains. It is recommend to periodically inspect the sun roof drain for debris and clean as necessary.

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.

The AC compressor may fail causing the AC system to blow warm air, smoke may also appear from the engine. A failed AC compressor will require replacement. Mazda has extended the warranty on these compressors to 5 year or 60K mikes. If these conditions are noted our technicians recommend to turn the AC system off and have it inspected as soon as possible.

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.

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.

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.

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.
