16V-621Aug 25, 2016

Fuel System, Gasoline:Delivery:Fuel Pump

Ford Motor Company (Ford) is recalling certain model year 2013-2015 Ford Taurus, Ford Flex, Lincoln MKS and Lincoln MKT vehicles equipped with 3.5L GTDI Ecoboost engines and 2013-2015 Ford Taurus Police Interceptor vehicles. A component within the fuel pump electric module (PEM) may overheat causing a loss of electrical power to the fuel pump.

Risk and remedy

Risk: A loss of power to the fuel pump will cause the engine to stall or prevent the vehicle from starting, increasing the risk of a crash.
Remedy: Ford will notify owners, and dealers will inspect the fuel PEM part number and replace the fuel PEM, as necessary, free of charge. The recall began on December 1, 2016. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16S31.

14V-393Jul 2, 2014

Power Train:Axle Assembly:Axle Shaft

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 and remedy

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.
Remedy: 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.

Should you keep driving it?

This page can't tell you that. 1 of 35 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
