2007 Buick Lucerne Problems

Check Engine Light Due to Intake Manifold Vacuum Leaks

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.

Stalling Due to Failed Crankshaft Position Sensor

The crankshaft position sensor may fail causing the engine to stall intermittently, the Check Engine Light may or may not illuminate.

Coolant Leaks From Water Pump and Radiator

The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.

2007 Buick Lucerne Recalls

Ignition Lock Cylinder Concern

Excess weight on the key ring can cause the ignition switch to move out of the run position without warning, turning off the engine. This defect can also affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. Dealers will install two 13mm key rings and key insert into the vehicle's ignition keys to correct this concern.

Possible Under Hood Electrical Fire

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

Possible Under Hood Electrical Fire

The wiring to the washer system heater may overheat due to a failure in the heater module. This could cause other electrical features to malfunction, smoke to develop, and an electrical fire could result. Dealers will install a wire harness with an inline fuse to protect the washer heater module. This recall is expected to begin on September 12, 2008. The General Motors recall number is 08048.

I purchased my 2007 Buick Lucerne in July of 2006. It was on the dealers showroom floor and I fell in love with it. After 7 1/2 and 71,000 miles, I still enjoy driving it. It's the best car by far that I have ever owned. The dealer in Summerville SC I purchesed it from is the only place I have ever had it serviced. They preform the required maintenance and don't pressure to have things don...
I bought my 2007 Lucerne used with almost 27K miles. I now have over 94K. I love the reliability of this car (hope I didn't jinx myself). I love the roomy interior. My only complaints are the lack of glove compartment space and the blind spots. The many airbags take up a good bit of room and I notice quite a few blind spots. Only other problem was the tail lights, they seemed to go quicker than...
