Known Problems

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

A Loose or worn gas cap may cause Check Engine Light to illuminate.

The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern.

A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

Brake fluid can become dirty and may cause problems with the hydraulic system parts in the brake system.  We recommend flushing the fluid at least every 60,000 miles.

The front and rear light bulbs are prone to premature failure. Our technicians tell us that the front bulbs can be very difficult to replace.
