Ford Motor Co. is expanding its door latch safety recall to include about 156,000 more cars, bringing the total to 545,906 vehicles in North America.

Ford agreed to the recall expansion at the request of the National Highway Traffic Safety Administration. Ford dealers will replace all four door latches at no cost to the customer.

The recall includes:

• Certain 2011-2014 Fiesta vehicles built at Cuautitlán Assembly Plant from Nov. 3, 2009, to May 31, 2013

• Certain 2013-14 Fusion vehicles built at Hermosillo Assembly Plant from Feb. 1, 2012, to May 31, 2013

• Certain 2014 Fusion vehicles built at Flat Rock Assembly Plant from April 12-26 in 2013

• Certain 2013-14 Lincoln MKZ vehicles built at Hermosillo Assembly Plant from Feb. 1, 2012, to May 31, 2013.

In these vehicles, the door latch pawl spring tabs may break. As a result, the doors may not latch properly or may unlatch unexpectedly while the car is in operation.

“Ford is aware of two allegations of soreness resulting from an unlatched door bouncing back when the customer attempted to close it, and one accident allegation when an unlatched door swung open and struck an adjacent vehicle as the driver was pulling into a parking space,” the company said in a released statement.

A total of 456,440 of the recalled vehicles are in the U.S. and federalized territories. The remaining cars are in Canada (50,681) and Mexico (38,785).
