Vehicles with a V6 engine may develop an engine misfire under load (acceleration). This can be caused by a valve cover gasket leaking oil into a spark plug well, shorting the spark plug to the cylinder head. To repair this concern, the valve cover needs to be resealed and the spark plugs and wires should be replaced.

I went in for an oil change today at the Mazda dealership and was told that I had a battery cable corrosion issue. My service rep told me the cable wires that attach to the battery are corroded and that I would need to replace them with a new wiring harness as soon as possible. Due to this problem, I also need a new battery. The estimated cost is $600. The service rep said at any time the cables could snap causing the car to completely sto...

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.

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 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.

If the engine cranks but will not start, it may be due a failed distributor. In the diagnosis, it may be discovered that the Electronic Engine Control (EEC) Unit is the cause if ignition spark is restored after disconnecting the Spark Output (SPOUT) Connector.

Our technicians report the original paint tends to fade and the clear coat peels off, though many cars have now been repainted.

Water intrusion into a connector (X309) located under the cab, beneath the driver's seat, can cause a rough idle, erratic speedometer operation, ABS Light and Check Engine Light illumination, and automatic transmission shifting problems. If needed, connector repair parts are available from Mazda dealers, and possibly some Ford dealers.

A leaking coolant pump can leak onto the timing belt and cause it to tear. Our technicians recommend replacing the coolant pump and timing belt every 60,000 miles to help avoid this problem. It is also important to follow the fill procedure for coolant on this engine to avoid problems.

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

Be sure to check your owner's manual and use the correct engine oil. Mazda does not recommend using synthetic oil in the RX-8's rotary engine.

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

Some models may have a problem where the Check Engine light illuminates indicating an improperly tightened fuel cap. Due to improperly manufactured threads on the fuel filler pipe, the filler pipe may need to be replaced.

The flywheel can warp causing a shudder when the vehicle is in reverse.
