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.

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).
