Known Problems

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.

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

The fuel pump may fail causing engine to stall and not restart.

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

It is common for the driver side window motor and master window switch to fail.

The mass air flow (MAF) sensor may fail, resulting in drivability issues and/or illumination of the Check Engine Light.

Air flow from the dash vents may be incorrect due to a damaged engine vacuum hose near the battery tray.

The engine temperature sensor wire for the engine temperature gauge, or warning light, may touch the rear exhaust manifold causing a short to ground causing erratic operation of the temperature gauge or warning light.

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

A coolant leak may develop form the Intake manifold gasket causing overheating complaints. The coolant leak may be internal allowing coolant to mix with the engine oil, this condition can result in internal engine damage.

If the spark plugs are not replaced at 80,000 miles, the spark plug wires may burn and damage the ignition coil pack.

On vehicles with a 3.1L engine, the front motor mount may break, causing the engine to jump while shifting gears or accelerating; this can break the water neck (thermostat housing) resulting in coolant loss and engine overheating.

On the 3.1L engines, oil leaks from the O-ring on the oil pump drive, the front crank seal, the oil pan gasket, and the oil sending unit are quite common.

It is common for the power steering pumps to leak fluid.
