Buick LaCrosse RecallsFront Seat Mounted Side Air Bags Inflators Rupture
The front seat mounted side air bag inflators may rupture and spread metallic debris through the passenger compartment, possibly causing occupant injury or death. Dealers will replace the side impact air bag modules free of charge to resolve the concern.

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.
