2016 Ford Flex Recalls, Issues & Maintenance

The 2016 Ford Flex carries 3 open NHTSA recalls — most recently covering turbo/supercharger and rear. Owners report 7 recurring issue clusters, led by “Rearview camera failure (Back Over Prevention recall).” Ford uses the Intelligent Oil-Life Monitor (IOLM) to determine when oil changes are due based on actual driving load — not just mileage. Ford's published cap is 10,000 miles or 1 year, whichever comes first. The schedule below reflects Ford's Normal service intervals; F-Series trucks and Super Duty have additional towing-specific items.

Issue: Ford Motor Company (Ford) is recalling certain model year 2016 Ford Taurus, 2016-2017 Ford Flex, Lincoln MKT, 2017 Ford Explorer and Ford Explorer Police Interceptor Utility vehicles equipped with 3.5L GTDI engines. Improperly brazed turbocharger oil supply tubes may leak oil on engine components.

Risk: An oil leak, in the presence of an ignition source, increases the risk of a fire.

Fix: Ford will notify owners, and dealers will inspect, and if necessary, replace the turbocharger oil supply tubes, free of charge. The recall began on January 31, 2017. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 16S46.

SUSPENSION:REAR

Campaign #20V072000 · Oct 2, 2020

Issue: 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.

Fix: 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.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Campaign #25V695000 · Oct 13, 2025

Issue: Ford Motor Company (Ford) is recalling certain 2015-2019 Flex, 2015 Explorer, Lincoln MKT, Lincoln MKZ, 2015-2016 C-Max, Escape, Taurus, 2016 Fusion, 2018-2019 Taurus, 2019 Lincoln MKT, Fiesta, and 2020 Mustang vehicles. The rearview camera may display a distorted, intermittent, or blank image when the vehicle is in reverse.

Risk: A rearview camera that fails to properly display an image can reduce the driver’s view behind the vehicle, increasing the risk of a crash.

Fix: Dealers will inspect and replace the rearview camera as necessary, free of charge. This will be a phased campaign, with the remedy becoming available in different phases based on model and model years. Interim letters notifying owners of the safety risk were mailed on October 25, 2025. Additional letters will be mailed once the final remedy is available on each phase. Mustang owner notification letters were mailed January 2, 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25SA9.

Essential maintenance

Critical for safety and preventing major damage

Engine Oil & Filter

Every 7,500 mi

Replace synthetic-blend or full-synthetic Motorcraft oil per the IOLM, or every 7,500-10,000 miles. EcoBoost engines require full synthetic; Coyote 5.0L V8 specifies SAE 5W-30.

Estimated cost — typical U.S. ranges

Dealer

~$120–$160

Shop

~$85–$115

DIY

~$25–$55

Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.

Tire Rotation

Every 10,000 mi

Rotate tires every 10,000 miles, or with every other oil change. F-150 4x4 owners should rotate every 5,000-7,500 miles to even out drivetrain bias wear.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Often free at the shop where you bought the tires — worth asking before paying.

Brake Inspection

Every 10,000 mi

Inspect brake pads, rotors, and brake fluid level every 10,000 miles. Front pads on F-150 and Explorer typically last 40,000-60,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$85

Shop

~$60

DIY

Free

Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.

Brake Fluid

Every 45,000 mi

Ford specifies brake fluid replacement on an inspection basis, but moisture testing every 3 years is recommended. Replace if reading exceeds 3% water content.

Estimated cost — typical U.S. ranges

Dealer

~$180–$200

Shop

~$125–$140

DIY

~$10–$25

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.

Important maintenance

Keeps your vehicle running smoothly and efficiently

Engine Air Filter

Every 30,000 mi

Replace the engine air filter every 30,000 miles. EcoBoost turbocharged engines are sensitive to airflow restriction — don't extend.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

5-minute job on most cars; the airbox lid usually has clips, no tools needed.

Automatic Transmission Fluid

Every 150,000 mi

Ford 6R80, 10R80, and 8F transmissions use Mercon LV fluid rated 150,000 miles under normal service. Severe service (towing, plowing) drops this to 60,000 miles.

Estimated cost — typical U.S. ranges

Dealer

~$330–$500

Shop

~$235–$355

DIY

~$60–$180

Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.

Transfer Case Fluid (4WD models)

Every 60,000 mi

F-150 4x4 and Bronco 4x4: replace transfer case fluid every 60,000 miles. Use Motorcraft XL-12 — do not substitute generic transfer case fluid.

Estimated cost — typical U.S. ranges

Dealer

~$105–$140

Shop

~$75–$100

DIY

~$15–$40

AWD/4WD vehicles only. Easy drain-and-fill on most platforms.

Rear Differential Fluid

Every 100,000 mi

F-Series and Expedition: replace rear axle fluid every 100,000 miles, or 50,000 miles if towing. Limited-slip rear ends require friction-modifier additive.

Estimated cost — typical U.S. ranges

Dealer

~$150–$195

Shop

~$105–$135

DIY

~$20–$50

Drain plug + fill plug — straightforward DIY. AWD vehicles have two; budget for both.

Spark Plugs

Every 100,000 mi

Iridium spark plugs on Coyote 5.0L, EcoBoost 2.7L/3.5L, and 2.3L are rated 100,000 miles. EcoBoost engines: never exceed the interval — gap erosion causes coil failure.

Estimated cost — typical U.S. ranges

Dealer

~$285–$390

Shop

~$200–$275

DIY

~$25–$100

Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.

Engine Coolant

Every 50,000 mi

Motorcraft Orange (Dex-Cool compatible) coolant: first change at 100,000 miles, then every 50,000. Older trucks with Yellow Motorcraft coolant: 50,000 miles throughout.

Estimated cost — typical U.S. ranges

Dealer

~$285–$330

Shop

~$200–$235

DIY

~$25–$60

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.

Recommended maintenance

Extends the life of your vehicle and improves comfort

Cabin Air Filter

Every 20,000 mi

Replace the cabin air filter every 20,000 miles. On F-150, located behind the glove box; on Escape and Explorer, accessed from the passenger footwell.

Estimated cost — typical U.S. ranges

Dealer

~$60–$95

Shop

~$45–$70

DIY

~$15–$40

Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
