Known Problems

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

The automatic transmission shifter may fail, or a wire may break near the shifter causing the ignition key to become stuck in the ignition lock cylinder.

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

Erratic and hard shifting can occur from a failed transmission pressure control solenoid. To fix this issue, a partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

Acid may leak from the battery at the cable connections, resulting in corrosion on the battery cable ends and in the battery tray. A Leaking battery should be replaced and the cables thoroughly cleaned or replaced if necessary.

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

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

The 2006-2011 Chevrolet Impala 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.

An engine oil leak may develop from the front crankshaft seal. Our technicians tell us a revised front crankshaft seal is available to correct this concern.
