Known Problems

If the ABS light on the instrument panel illuminates, our technicians recommend checking the brake lamps first. It could indicate that a brake light is not working or has burned out.

This engine may leak oil from the valve cover gasket.

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.

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.

Contaminated brake fluid can cause problems in the brake system and it should be flushed every 60,000 miles.

It is very 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 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.

Our technicians highly recommend that the engine coolant be replaced every 30,000 miles.

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

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

A ticking noise may develop from the engine due to a cracked exhaust manifold. Damaged exhaust manifolds will require replacement to correct this issue.

The display on the heater and AC control panel may become dim or go completely blank. Our technicians tell us the control panel must be replaced to correct this fault.

The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally 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 your local GM dealer to find out what the latest repair is for this condition.
