Known Problems

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

The ignition coil housing may fail causing an engine misfire on one or more cylinders.

The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.

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

The front or rear exhaust manifold may crack causing an exhaust leak. Our technicians tell us the manifold should be replaced to correct this condition.

The engine vacuum hose to the MAP sensor may crack resulting in a vacuum leak causing the engine to run rough and/or stall.

The timing chain tensioner and guides are prone to wear and may develop an abnormal noise, requiring replacement.

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

The 2.3L 4 cylinder engine can be prone to head gasket failure. This can result in coolant loss and engine overheating.

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.
