When that happens, the air bags may not deploy in a crash.
The company has already recalled Chevy Cobalts from 2005 through 2007 model years and Pontiac G6s from 2007.
Now, GM says it is also recalling Saturn Ions from 2003 to 2007 model years, Chevy HHRs from 2006 and 2007 and Pontiac Solstice and Saturn Sky models from 2006 and 2007.
The recall is to correct a condition with the ignition switch where the key may unintentionally move or switch to the "accessory" or "off" position, turning off the engine and most electrical components on the vehicle.
In all, the recall affects more than 1.3 million vehicles.
