The recall involves the 2012-2014 Ford Edge and Lincoln MKX; the 2013-2014 Ford Flex and Lincoln MKT; and the 2013-2014 Ford Taurus and Lincoln MKS.
The company says that due to the improper installation of a clip in the axle, the halfshaft can disengage from the linkshaft. If that happens, power won't be transmitted to the wheels, increasing the risk of a crash. Also, the vehicles could roll out of the "park" position if the emergency brake isn't engaged.
Ford says there have been no reports of injuries or accidents related to the defect.
Ford will notify owners and begin free repairs by the end of August.
