CHICAGO -- General Motors (IW 500/4) announced on Friday that it  will recall about 55,000 vehicles in the United States to fix a defect that could cause them to roll away after the car was parked.

GM said it is not aware of any injuries or accidents as a result of the defect, which it will correct free of charge.

It has discovered that some of the vehicles were built with a fractured park lock cable or a malformed steering column lock. This could allow the vehicle to shift from the park position once the key is removed or in the "off" position.

"Either of these scenarios may cause the vehicle to roll away after the driver has exited the vehicle, resulting in a possible vehicle crash and/or injury," GM said in regulatory filings.

The recall affects certain 2013 models of the Cadillac Escalade, Escalade EXT and Escalade ESV; Chevrolet Express, Silverado, Tahoe and Suburban and GMC Savana, Sierra, Yukon and Yukon XL.

"About one in 1,000 of the recalled vehicles are expected to have the defect, and the majority of those were believed to be on dealer lots or on their way to dealers," GM said.

All unsold vehicles are being inspected, and GM will also send notices to new owners to bring their vehicles in to be checked.
