NHTSA lists 2 safety recalls and 106 owner complaints for the 2009 Buick Lacrosse. Most complaints involve exterior lighting (47) and electrical system (31).
General Motors LLC (GM) is recalling certain model year 2007 Pontiac Grand Prix, 2006-2009 Buick LaCrosse, 2006-2007 Buick Rainier, Chevrolet Trailblazer, GMC Envoy, 2006 Chevrolet Trailblazer EXT, GMC Envoy XL, 2006-2008 Isuzu Ascender, and Saab 9-7x vehicles. In the affected vehicles, the headlamp driver module (HDM) may overheat and fail, causing the headlamps and daytime running lights to not illuminate.
This defect can 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. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.

“WAS DRIVING DOWN ROAD GOT TO MY DESTINATION PARKED IT AND WHEN I CAME OUT IT WOULD NOT START FOUND A BURNT FUEL PUMP RELAY CHANGED IT AND DROVE IT HOME. 20 MIN LATER I DROVE IT AGAIN AND MADE IT 2 MILES SAME THING HAPPENED TO RELAY ONLY WHEN I WAS DRIVING IT.”
“The passenger airbag light started coming on and going off intermittently. After several weeks of this, it was on every time the car is driven. Testing by an ASE certified mechanic revealed that the permanent light results in no front seat airbags. The failed part is the seat presence sensor. The part is - and hasn't been for quite a while - manufactured by GM. Aftermarket parts are costly and the installation cost is in the hundreds of dollars. Research indicates that this is a well-known and long reported issue. Why not a recall years ago? Other than brakes and steering, could there be any more unsafe components than those affecting airbags? The only remedy other than continuously replacing the faulty part, is a bypass module. If it functions correctly, the airbag will deploy regardless of passenger weight. This puts any child or underweight rider in danger. And, of course, considering the expense, many owners will do nothing with possibly grave consequences. I think you "dropped the ball" big time on this one!”
