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.

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.

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.

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.

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

Heater core leaks are common in this model, more so if the wrong anti-freeze/coolant is used in the cooling system.
