2009 Buick LaCrosse Recalls

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.

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.
