Known Problems

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

A fluid leak may develop from the transmission output shaft seal. This leak may cause the transmission mount to become oil soaked and require replacement of the mount along with the leak repair.

The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.

Timing gears may wear causing a mild to severe knocking noise from the front of the engine. Replacement of the timing gears is necessary.
