Known Problems

The power door lock actuators may become slow to operate or stop working completely and require replacement.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

The inside and outside door handles are prone to breaking.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

The engine idle may be lower than normal due to deposits built up on the throttle body, which can restrict air flow at idle. To low of an engine idle can result in a stalling condition. Performing a throttle body service will generally correct this concern.

Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.
