Known Problems

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

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.

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.
