Known Problems

The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.

 

The Chevrolet Impala SS has known issues with the EVAP system, a part of your emission control system.

The EVAP canister vent valve or valve solenoid wiring may fail causing illumination of the check engine light, setting code P0446, and problems filling the tank with fuel.

To correct the issue, the EVAP canister vent valve, solenoid, and wiring must be inspected. The most common fix is replacement of the wiring connector or replacement of the vent valve assembly.

A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

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.

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.

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.

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

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. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

The water pump may develop a coolant leak resulting in an engine overheating condition.

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

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.
