2007 Buick LaCrosse Recalls

Headlights & Daytime Running Lights

These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.

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.

Fuel or Fuel Vapor May Leak from Fuel Tank

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.

This is defiantly a poor design. Hopefully they f...
Though I only have 30k on my CXS, it has been a dependable car. Handles well, looks great and has some power with the 3.6. I have experienced the common gas cap and steering "clunk" problems which were addressed by the dealer as well as a faulty speed sensor, all within the last 5k miles. This is my third Buick since a 1984 Regal and they all have been comfortable, reliable, low maintenan...
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.
