Known Problems

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

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

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 ignition switch may fail causing a no start condition. This is not generally a theft system (passlock) issue because the security light does not illuminate or flash.

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

It is common for the high pressure power steering rubber hoses to leak. Our technicians recommend replacing leaky rubber hoses to prevent the loss of power steering.

The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.

Corrosion may develop at the connection between the ignition coil tower and spark plug wire resulting in an engine misfire. The Ignition coil and spark plug wire should both be replaced to correct this condition.

An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.

A weak battery or a burned out brake light bulb may cause the ABS light to illuminate.

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

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

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.

Front brake rotors can wear causing a pulsation felt in the brake pedal. Our technicians often recommend replacement of the front rotors and brake pads as the best option to correct this condition.

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.
