What is wrong: 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.
Risk: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1‑800‑521‑7300 (Buick), 1‑800‑458‑8006 (Cadillac), and 1‑800‑222‑1020 (Chevrolet). GM's number for this recall is 14299.

At 80xxx miles the drivers front door lock actuator became inoperative. At 90xxx miles the passenger front door lock actuator became inoperative. At 96xxx miles the passenger rear door lock actuator became inoperative. Each runs $250-300 to repair. Not repairing leaves the door unlocked (while driving) or unlocked (while parked and vehicle becomes accessible to anyone) or the door remains locked when trying to exit or enter. In an emergency, this may cause problems. Searching the internet, there are many complaints about this on the lacrosse.

The air bag light comes on intermittently. I took it in for service, and was told it would be $1300 to replace the passenger presence module. I've seen other complaints online regarding this same item. I've also had issues with the automatic locks. It initially started with the passenger front door, and has now progressed to all the doors. The price I was given to repair this was $1600. Again, I've seen numerous online complaints concerning this item. This is my 3rd buick, and I do not intend to buy another one. It seems once the warranty expires, several costly repairs are incurred.

In january of 2015 the electronic door lock system began to malfunction. The remote first failed to control the right rear door. Then the malfunction spread to the left front door lock. The situation became worse until the entire locking system could only be controlled manually. Even then the physical key control frequently malfunctioned. Safety hazards were created including locking the keys inside an unoccupied running vehile, being totally unable to unlock the vehicle, and generally inconsistent ability too maintain control over the vehicles locking status. Approximately $1,000 dollars have been spent using genuine gmc parts to correct the problem. It is still unstable and in a deteriorated condition.
