When owners reported it
Related recalls (2)
Air bags:sensor:occupant classification; electrical system:wiring
Problem: General Motors LLC (GM) is recalling certain model year 2009-2010 Chevrolet Impala vehicles manufactured April 25, 2008 through February 16, 2010. The front passenger seat frame may contact and damage the wires of the passenger presence sensor module.
Risk: If the wires are damaged, the passenger presence sensory system may fail to recognize that the passenger seat is occupied, disabling the air bag. Damage may also cause the air bag fuse to short resulting in a loss of all air bags and seat belt pretensions. Both conditions increase the risk of injury during a crash.
Fix: GM will notify owners, and dealers will double wrap the wires with anti-abrasion tape and replace damaged wires as necessary, free of charge. The recall began on August 1, 2016. Owners may contact Chevrolet customer service at 1-800-521-7300. GM's recall campaign number is 36110.
Electrical system:ignition
Problem: 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.
Fix: 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.
