If engine misfiring, rough running, or fuel consumption issues are not resolved quickly, the catalytic converter can overheat and fail.
Pay close attention to warning lights and have the brakes inspected regularly—immediately address any brake problems. Hard driving habits will cause excessive brake pad and rotor wear.
Issues with the air flow meter flap or calibration can cause fuel mixture control problems.
The cooling system must be inspected regularly, as small leaks can develop at the reservoir. The heater valve and fan operation should also be inspected.
The release arm for the throw out bearing can bind and cause problems with the clutch. Flywheel wear can cause driving and shifting problems and may cause the hubs to fail.
