Known Problems

The high pressure power steering hose will commonly leak fluid; it should be replaced.

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

Fuel injectors can short-circuit electrically causing a rougher than normal idle and reduced performance.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.

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

The oxygen (O2) sensor may fail causing the engine to burn to much fuel and may cause the check engine (SES) light to illuminate.

An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

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

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

The automatic transmission shifter may fail causing the ignition key to become stuck in the ignition lock cylinder.

The instrument panel and switch backlighting may fail due to a faulty dimmer control module. A failed module will require replacement.
