The National Highway Traffic Safety Administration on Wednesday urged owners of recently recalled Ford vehicles to get them "fixed as soon as possible."
The automaker on Friday issued a safety recall for about 390,000 newer cars with door latch issues. It affected some 2012-2014 Ford Fiestas, all 2013 Ford Fusions and Lincoln MKZs, and certain 2014 Fusions and MKZs.
A broken part in the doors can lead to difficulty in closing them, leaving the "potential the door may unlatch while driving," Ford said in the initial recall. The company noted two cases in which a door bounced back and hit individuals when they tried to close it.
The NHTSA told owners to look out for notifications from Ford and check vehicle identification numbers to see if a car is included in the recall.
"Ford and NHTSA share the same goal: we both want to ensure that vehicles are safe for customers," Ford said in a statement.
Ford shares closed 0.7 percent higher on Wednesday.
The automaker did not immediately respond to a request to comment.
