Known Problems

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

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

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

Extensive transmission damage can occur in some of the automatic transmission models when the transmission oil cooler fails and allows coolant to mix with the automatic transmission fluid.

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

Oxygen sensor and coolant temperature sensor failures are common.

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

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.

Throttle body failure is not uncommon and can lead to shifting issues with the automatic transmission and other drivability concerns.

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.

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.

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

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.
