02 / Official safety campaigns

5 recall campaigns on file.

A campaign can cover only certain production dates or configurations. The count does not tell you whether an individual car has an open recall.

Jul 3, 2014 Safety recallELECTRICAL SYSTEM:IGNITIONCampaign 14V400000

Reported concern

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) notified the agency on July 3, 2014, that they are recalling 5,877,718 model year 2000-2005 Chevrolet Impala and Monte Carlo, 1997-2003 Chevrolet Malibu, 2004-2005 Malibu Classic, 1999-2004 Oldsmobile Alero, 1998-2002 Oldsmobile Intrigue, 1999-2005 Pontiac Grand Am and 2004-2008 Pontiac Grand Prix vehicles. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.

Manufacturer’s stated response

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 9, 2014. GM's number for this recall is 14350.

Vehicle Wide Programming (VWP) is a new process to update software on GM Vehicles. It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.
