General Motors has issued a recall on its 2013 Cadillac Escalade, plus several other of its top-selling SUVs and pickups. The cause of the recall is due to a potential fault with the vehicles' ignition system.

The recall affects 2013 Cadillac Escalade, Escalade ESV, and Escalade EXT models, as well as the related Chevrolet Avalanche, Express, Silverado HD, Silverado LD, Suburban, and Tahoe, and the GMC Savana, Sierra HD, Sierra LD, Yukon, and Yukon XL.

And then it is only those models built from November 7, 2012, through December 18, 2012.

According to General Motors Company [NYSE:GM], there are some 54,686 vehicles affected by the recall.

The issue stems from the affected vehicles possibly being manufactured with a fractured park lock cable or a malformed steering column lock actuator gear in the lock module assembly. This may lead to the vehicles shifting out of the “Park” position with the ignition key removed or the ignition key in the “OFF” position.

The vehicles may also shift out of Park without application of the brake pedal while the key is off.

Should any of these scenarios occur, the vehicles may end up rolling away after the driver has exited and potentially cause a crash.

GM is in the process of notifying owners. They will be requested to take their vehicles to their nearest Cadillac, Chevrolet or GMC dealer, which will inspect the vehicle and replace the steering column as necessary, free of charge.
