Known Problems

The alternator may fail causing the battery to go dead. The charge light on the dash may or may not illuminate. The alternator may also develop an abnormal noise. A failed alternator will require replacement.

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.

A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
