ELECTRICAL SYSTEM:IGNITION · Campaign 14V355000 · Jun 23, 2014
Defect: 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.
Consequence: 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.

A RECALL WAS IMPLEMENTED IN 2008 TO ADD A FUSE TO THE CONTROL CIRCUIT HARNESS TO ADDRESS THE POTENTIAL CONSEQUENCES OF A PRINTED CIRCUIT BOARD (PCB) ELECTRICAL SHORT. HOWEVER, THERE HAVE BEEN NEW REPORTS OF THERMAL INCIDENTS ON HWFS MODULES AFTER THIS IMPROVEMENT WAS INSTALLED. THESE INCIDENTS RESULTED FROM A NEW FAILURE MODE ATTRIBUTED TO THE DEVICE'S THERMAL PROTECTION FEATURE. THE SIGNIFICANCE VARIES FROM MINOR DISTORTION TO CONSIDERABLE MELTING OF THE PLASTIC AROUND THE HWFS FLUID CHAMBER.
Consequence: IT IS POSSIBLE FOR THE HEATED WASHER MODULE TO IGNITE AND A FIRE MAY OCCUR.
Remedy: DEALERS WILL PERMANENTLY DISABLE AND REMOVE THE HEATED WASHER FLUID MODULE. AN UPDATED PAGE FOR THE OWNER MANUAL WILL BE PROVIDED AND INSERTED IN THE OWNER MANUAL TO DOCUMENT THAT THE FEATURE HAS BEEN PERMANENTLY DISABLED AND REMOVED FROM THE VEHICLE.
