Known Problems

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

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.

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.

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

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

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

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.

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

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