Known Problems

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

The engine may develop an oil leak from the lower crankcase portion of the engine block. Our technicians tell us that the engine must be removed from the vehicle to properly repair this oil leak.

The 2006-2011 Buick Lucerne is known to have 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.
