General Motors is recalling 12,626 2013 Cadillac XTS sedans built between October 12, 2011 through August 30, 2012 in the United States for the same defect that issued a recall in Canada: faulty head restraints. As a refresher, the head rests may not lock in the upright position after being folded forward. Of course this increases the risk of a neck injury. Therefore, General Motors will notify owners, and dealers will replace the head restraints, free of charge. Owners may also contact General Motors at 1-800-458-8006.
