Ford Motor Co. is recalling certain model year 2013 Ford Explorer, Taurus and Lincoln MKS vehicles manufactured Nov. 29, 2012, through Dec. 12, 2012.

In the affected vehicles, with sufficient door openings and closings, the child safety locks may change from an activated position to a deactivated position without notice, according to the National Highway Traffic Safety Administration.
