The mass air flow (MAF) sensor may fail, resulting in drivability issues and/or illumination of the Check Engine Light.

Engine oil leaks are common from the valve cover gaskets and camshaft chain tensioner gasket.

One or both head lights may not work due to premature head light bulb burnout and/or bulb harness failure. Care should be taken to inspect the head light harness connector for damage when replacing bulbs. Damaged connectors should be replaced.

The water pump may fail resulting in engine overheating and possible timing belt damage. Overheating and/or timing belt failure can result in very expensive engine repairs. As a precaution, it is recommended to inspect the timing belt and water pump at regular intervals.

Electrical issues that are difficult to diagnose—and sometimes intermittent—are typically due to ground wiring issues. The most troublesome ground locations are under the battery or at the engine.

A coolant leak may develop after oil filter replacement. The coolant o-ring seal can be damaged if the oil filter housing turns when removing or installing the oil filter. The recommended procedure is to hold the filter housing when tightening or loosening the oil filter.

The water pump and/or other cooling system may develop a coolant leak. Oil leaking from the  valve cover gasket is also common.

An ignition coil or spark plug may fail unexpectedly resulting in an engine misfire and possible illumination of the Check Engine Light. Vehicles equipped with spark plug wires may also develop a misfire caused by a failed spark plug wire.

Reverse gear failures and noise in the manual transmission models are common.

The Check Engine Light may illuminate because of evaporative (EVAP) emission failures and/or intake manifold vacuum leaks.

Due to an ignition component and/or engine coolant temperature sensor failure, the Check Engine Light may illuminate. Replacement of the failed component will be necessary to correct this concern.

A dirty or failed throttle body can cause various drivability issues and illumination of the Check Engine Light.

The rear brakes tend to wear out quickly; rotors may need replacement by the first brake job. Our technicians recommend that the brakes be inspected for wear regularly.

A damaged water pump impeller may cause an engine overheating condition. Our technicians tell us the repair should include replacement of the water pump, thermostat, and flushing the cooling system.

Erratic turn signal operation can be a result of a failing turn signal flasher relay which will require replacement.
