Turns out the scale of General Motor’s Ignition switch debacle is bigger than expected, as the auto maker expands the recall. Affected cars include various Chevrolet, Pontiac and Saturn models, built from 2003 to 2007. The total number of recalled vehicles is 1,367,146.

The models now involved in GM ignition switch recall include 2003-2007 Saturn Ions, 2006-2007 Chevrolet HHRs, and 2006-2007 Pontiac Solstice and Saturn Sky, 2005-2007 Chevrolet Cobalts and Pontiac G5, and Pontiac Pursuit sold in Canada.

The affected cars have a problem with ignition switch that may shift itself to accessory or off position. If this happens while the vehicle is moving, the engine will be shut, which means you will have almost no control over the steering and brakes. It also shuts down the electrical systems, which means if you crash – because you have no steering or brakes – the airbag won’t deploy.

GM will notify all affected customers and will work with them on an individual, case-by-case basis to minimize inconvenience while performing repairs at no charge to the owners.
