Known Problems

An external Engine oil leak may develop from the distributor O-ring seal. A new O-ring seal will be needed to correct this leak.

For the 2.3L 4 Cylinder and 5.0L V8 engine, the electrical ignition switch poses a fire hazard. An updated switch is available.

While steering, if you hear a clunk or a rattle, or if you experience premature tire wear, this could indicate the inner tie rod ends are loose or worn and will require replacement.

If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

On higher mileage vehicles, one or more EGR orifice in the intake manifold may plug with sludge. This can cause the engine to misfire when first accelerating because too much exhaust gas is directed into the cylinders where the orifice is not plugged. Cleaning the clogged passages should correct this concern.

An oil leak may develop from the the right side head gasket.  Oil from this type of leak will commonly drip onto the starter. Our technician tell us an updated head gasket is available to correct this concern.

The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.

The exhaust manifold often warps and cracks, breaking off the studs between the cylinder head and the exhaust manifold. A ticking type noise may be noted most noticeable when the engine is cold.

The intake and valve cover gaskets may leak oil.

Valve seats (components in the cylinder head that help seal the valve) can fall out. When this happens, it causes rough running and creates noise. Replacement of the cylinder head is commonly required to fix this problem.

The rear window wiper may not fully contact the rear window. To fix, replacement of both the wiper blade and wiper arm is necessary. 

Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.

The instrument cluster (IC) may reset to its default settings when the ignition is turned off. Our technicians tell us revised IC programing is available which should correct this concern.
