NHTSA's VIN data lists these trims for the 2013 Flex. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 580 complaints with NHTSA about the 2013 Flex. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 6 recall campaigns for the 2013 Flex over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Ford Motor Company (Ford) is recalling certain 2013-2018 Lincoln MKT and Ford Flex and Taurus vehicles with the Police Interceptor or SHO Performance Pack. The rear suspension toe links may fracture due to stress on the rear suspension.
Risk: A fractured rear toe link will cause a sudden change in vehicle handling and increase the risk of a crash.
Remedy: Ford will notify owners, and dealers will replace the rear suspension toe links, free of charge. Remedy parts are not currently available. Owners were notified about the recall on March 3, 2020. A second notice will be mailed when remedy parts become available, which is currently expected to be the end of September 2020. The recall began October 28, 2020. Owners may contact Ford customer service at 1-866-436-7332 or Lincoln customer service at 1-800-521-4140. Ford's number for this recall is 20S04.
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: 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.
Ford Motor Company (Ford) is recalling certain model year 2013 Explorer, Explorer Police Utility, Taurus, Taurus Police Interceptor, Flex, Lincoln MKS, and Lincoln MKT vehicles. In the affected vehicles, the fuel delivery module may crack, allowing fuel to leak.
Risk: A fuel leak in the presence of an ignition source may result in a fire.
Remedy: Ford will notify owners, and dealers will replace the fuel delivery module, free of charge. The recall began on December 21, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 13S04-S1.
Ford Motor Company (Ford) is recalling certain model year 2011-2012 Ford Fusion vehicles without a 3.5L engine and Lincoln MKZ hybrid electric vehicles, 2011 Mercury Milan vehicles, 2011-2012 Ford Taurus, Ford Flex, Lincoln MKS, and Lincoln MKT vehicles equipped with a 3.5L GTDI engine and 2013 Ford Taurus, Ford Flex, Lincoln MKS, and Lincoln MKT vehicles equipped with any available engine. The affected vehicles have electric power steering assist systems that may shut down as a result of a steering motor sensor fault.
Risk: If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, increasing the risk of a vehicle crash.
Remedy: Ford will notify owners, and dealers will check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTC). If dealers find any loss of steering assist DTCs, the steering gear will be replaced, free of charge. If, no codes are found during the PSCM inspection, the PSCM software will be updated, free of charge. The recall began on July 21, 2015. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 15S18.

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.
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.
