Known Problems

An engine vacuum leak may develop from the throttle body gasket causing a higher than normal idle speed. Failed gaskets should be replaced.

The intake manifold gasket may develop an external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

The steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.

One or more fuel injectors may become stuck closed causing an engine misfire  and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.

The inside and outside door handles are prone to breaking.

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.

The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2000-2003 models is #4114K (trade number).

One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

A clicking noise may be noted from the turn signal flasher after the turn signals are switched off.  This is commonly cause by a faulty turn signal switch which will require replacement.

The CD player may fail due to an internal fault with the radio. Our technicians tell us that in most cases, the radio unit will need to be sent to a specialty repair shop to correct this issue.

A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.

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

The rear axle bearings have been known to wear grooves in the rear axle shafts, creating a grinding noise and leaky axle seals. An indication that this problem has occurred is axle fluid leaking onto the wheel.

The engine may develop a misfire due to worn valve seats. This fault will cause the Check Engine Light to illuminate. Our technicians tell us the misfire may or may not be felt while driving. They further recommend that both cylinder heads be removed and thoroughly inspected and repaired as necessary.
