2007 Buick LaCrosse Recalls

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.

On some vehicles, the fuel tank may be missing the adhesive that bonds the barrier layer to the outer shell. This may allow fuel and/or fuel vapors to leak out between the layers, increasing the risk of fire. Dealers will inspect the serial numbers on the fuel tank and replace it if needed. The recall began November 13, 2006. The GM recall number is 06160.

I have been driving my 2007 LaCrosse for over 3 and a half years and the only issue I have is when I roll down the window the car gets a mildew smell, especially after a rain storm. Other tha that it has driven me through Western Ny weather like a champ.

I just bought this car last week, traded a 2000 Buick LeSabre for this 2007 Buick LaCross, I wish I had my other Buick back! I'm not happy with this car, with the air on it has no power, it keeps hesitating , I keep thinking it is going to die any minute. If I can get rid of this car, I will!!
