Problem: Ford Motor Company (Ford) is recalling certain model year 2012-2014 Ford Edge and Lincoln MKX vehicles manufactured September 2, 2010, to November 30, 2013; 2013-2014 Ford Taurus and Lincoln MKS vehicles manufactured August 25, 2011, to November 30, 2013; and 2013-2014 Ford Flex and Lincoln MKT vehicles manufactured September 12, 2011, to November 30, 2013. In the affected vehicles, the halfshaft retention circlip may not have been properly installed, and as a result, the halfshaft may move outward and disengage from the linkshaft while driving and without prior warning.
Risk: If the halfshaft and linkshaft become disengaged while driving, power will no longer be transmitted to the wheels, increasing the risk of a vehicle crash. Additionally, if the parking brake is not applied before exiting the vehicle, the vehicle may roll away despite the transmission being placed in 'Park', increasing the risk of injury to exiting occupants and bystanders.
Fix: Ford will notify owners, and dealers will inspect the vehicles to make sure that the halfshaft is properly retained. If it is not, dealers will replace the linkshaft and also replace the halfshaft if it shows evidence of spline damage, free of charge. The recall began on August 4, 2014. Owners may contact Ford customer service at 1-800-392-3673. Ford's number for this recall is 14S10.
