General Motors has expanded its car recall that was initially announced two weeks ago. The recall was issued because of a problem with the ignition switch that could result in the key shifting to the “off” or “accessory” position while the car is in operation. If this occurs, the engine and many of the electrical components of the car may turn off, resulting in an accident.

The expanded recall now reaches 1,367,146 GM cars in the U.S., including some models of the 2005-2007 Chevrolet Cobalt, 2003-2007 Saturn Ion, 2006-2007 Chevrolet HHR, 2006-2007 Pontiac Solstice and Saturn Sky as well as some 2007 Pontiac G5 models. With the additional cars being recalled, GM said that the number of reported accidents involving these cars also has grown, with 31 incidents causing or contributing to the non-deployment of the front air bags, resulting in 13 front-seat fatalities.

GM said that the problem is the result of the ignition switch not meeting torque specifications, allowing it to move out of the “run” position due to a heavy key ring, driving off road or “some other jarring event.” It advised consumers driving cars affected by the recall to use their ignition key alone, with nothing else on the key ring, until a dealer can complete the recall repair.
