Known Problems

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

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

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.

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.

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

One or more power windows may fail. Our technicians tell us this is commonly due to a failed window regulator which will require replacement.

Shifting issues due to internal problems in high mileage automatic transmissions can be difficult to resolve without transmission replacement.

The Check Engine Light may illuminate due to throttle valve related fault codes. The repair is to replace the appropriate connectors, if the problem persists the throttle body should be replaced.

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.

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.

Condensation in the heater case may cause a musty odor from the heating, ventilation and AC (HVAC) system after sitting for two hours or more. Our technicians tell us that a cleaner is available for the heater case and the drain system should be checked for debris.

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.

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

To avoid sludge accumulation inside the engine, our technicians recommend using the proper synthetic oil with the appropriate oil filter.

The Check Engine Light may illuminate as a result of a oxygen sensor and coolant temperature sensor fail. Replacement if the failed part will be necessary to correct this issue.
