2009 Buick Lucerne Problems
RepairPal has identified the most common problems with the 2009 Buick Lucerne based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The fuel pump may fail causing the engine to stall and not restart.
The 2006-2011 Buick Lucerne is known to have issues with the EVAP system, a part of your emission control system.
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 intake manifold vacuum leak can develop from a variety of sources, often causing illumination of the Check Engine Light with codes P0171 & P0174 stored. Thorough diagnoses will be necessary to pinpoint the cause in order to make the correct repairs. A "smoke" machine is often used to isolate the cause of difficult to find vacuum leaks.
A Loose or worn gas cap may cause Check Engine Light to illuminate.
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.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
