The recall covers door latches that may contain a broken pawl spring tab, preventing the door from totally latching.
There is potential for the door to come ajar while moving, increasing the risk of injury to the driver and other occupants.
The total amount of Ford vehicles affected stands at 545,906. This expansion of the recall adds an additional 156,000.
Ford reports two allegations of soreness resulting from an unlatched door bouncing back when the customer attempted to close it. Another documented case details an unlatched door swung open and struck an adjacent vehicle.
This happened as the driver was pulling into a parking space.
