GM recalled the 2013-2014 Chevrolet Tahoe and Suburban, 2013-2014 GMC Yukon and Yukon XL, 2014 Chevrolet Express and Silverado HD for issues regarding the chassis control module. Small metal fragments were responsible for causing the system to short circuit and make the affected vehicles stall.
In 2014 GM recalled over 10 million vehicles affected by a multitude of issues. GM issued a recall Feb. 25, 2014 for 1,620,665 vehicles that had an ignition switch flaw. The flaw causes vehicles to shut off unexpectedly and disables important safety features such as power steering, braking and airbag deployment. The design flaw resulted in a total of 100 fatalities for those driving the 2005-2007 Chevrolet Cobalt, 2003-2007 Saturn ION, 2006-2007 Chevrolet HHR and 2007 Saturn Sky, as well as the Open/Vauxhall GT and Daewoo G2X.
Over 7 million vehicles including the 2004-2008 Pontiac Grand Prix, 1997-2005 Chevrolet Malibu, 1999-2005 Pontiac Grand Am, 2000-2005 Chevrolet Impala and Monte Carlo were affected by the key being bumped out of the run position while the vehicle was being driven. Added weight on the key ring makes it much easier for the key to slip from the ignition cylinder. To avoid replacing parts of the ignition system, GM decided to redesign the key to allow it to hold more weight and avoid slipping.
