How Ford schedules service: Intelligent Oil-Life Monitor
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.

SEATS:MID/REAR ASSEMBLY
Campaign #21V765000 · 30/09/2021
Issue: Ford Motor Company (Ford) is recalling certain 2020-2021 Ranger Super Cab vehicles equipped with rear seats containing fixed head restraints. The fixed head restraints may interfere with proper installation of certain types of child seats. Additionally, the child seat may not attach properly to the lower-rear anchors. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 225, "Child Restraint Anchorage System."
Risk: An improperly attached child seat can increase the risk of injury in a crash.
Fix: Dealers will inspect the rear-lower child restraint anchorages for correct alignment and adjust as necessary. Separately, dealers will replace the non-removable head restraints with removable head restraints, free of charge. Interim owner notification letters were mailed on November 5, 2021. Owner notification letters were mailed on March 17, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 21C24.

FORWARD COLLISION AVOIDANCE: SENSING SYSTEM: RADAR
Campaign #21V982000 · 16/12/2021
Issue: Ford Motor Company (Ford) is recalling certain 2021 Ranger and Bronco vehicles. The cruise control radar module was misaligned during production.
Risk: A misaligned radar module may prevent the vehicle from maintaining a safe distance from other vehicles when adaptive cruise control is active. In addition, the automatic emergency braking (AEB) system may react slowly, or not react at all, during a pre-collision assist braking event. Any of these scenarios can increase the risk of a crash.
Fix: Dealers will adjust the angle of the cruise control radar module, free of charge. Owner notification letters were mailed January 21, 2022. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 21S52.

SEAT BELTS:FRONT:WEBBING
Campaign #21V811000 · 15/10/2021
Issue: Ford Motor Company (Ford) is recalling certain 2019-2021 Ford Ranger Super Cab vehicles. The front passenger outboard seat belt may not have been assembled properly, allowing the seat belt to be misrouted. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 208, "Occupant Crash Protection" and 209, "Seat Belt Assemblies."
Risk: A misrouted seat belt may not adequately restrain an occupant in a crash, increasing the risk of injury.
Fix: Ford will provide owners with instructions to perform a preliminary inspection of their front seat belts. Owners that detect an issue with the driver's seat belt, are unsure of the results, or do not want to perform an inspection, should not drive their vehicles and contact a Ford dealership. Dealers will inspect the front row outboard seat belts and replace them, if necessary, free of charge. Interim owner notification letters were mailed on November 5, 2021. Owner notification letters were mailed December 22, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 21C25.

EQUIPMENT:OTHER:LABELS
Campaign #23V379000 · 26/05/2023
Issue: Ford Motor Company (Ford) is recalling certain 2022-2023 Bronco, 2023 Super Duty F-250, and 2019-2023 Ranger vehicles. The Tire and Loading Information (TREAD) label states the incorrect load carrying capacity, which can result in an overloaded vehicle. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."
Risk: An overloaded vehicle increases the risk of a crash.
Fix: Ford will mail a new TREAD label to install over the existing label, free of charge. Owners will also have the option to take their vehicle to a Ford or Lincoln dealer to have the new label installed, free of charge. Owner notification letters were mailed July 21, 2023. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 23C18.

Campaign #25V442000 · 27/06/2025
Issue: Ford Motor Company (Ford) is recalling certain 2018-2022 Transit Connect, 2019-2020 MKZ, MKX, Edge, Continental, F-150, Nautilus, Fusion, 2019-2023 Ranger, Mustang, 2020-2021 EcoSport, Expedition, Navigator, 2020-2022 Escape, F-250 SD, Corsair, 2020-2023 Aviator, Transit, 2020-2024 Explorer, 2021-2024 Bronco Sport, and 2022-2024 Maverick vehicles. A software error may cause the rearview camera to display a blank image, or the image may remain on the display after the backing event has ended.
Risk: A rearview camera that displays a blank image can reduce the driver's view behind the vehicle. A rearview image that continues to be displayed after the vehicle is shifted out of reverse may distract the driver. Both of these situations can increase the risk of a crash.
Fix: Dealers will update the rearview camera software, free of charge. Owner notification letters were mailed September 4, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S72.

Issue: Ford Motor Company (Ford) is recalling certain 2016-2019 Lincoln MKC, 2016-2023 Explorer, 2019-2020 Fusion, 2019-2024 Ranger, 2020-2022 Lincoln Corsair, Escape, 2021-2024 Bronco, Bronco Sport, and 2022-2024 Maverick vehicles. The engine block heater may crack and develop a coolant leak, causing it to short circuit when the block heater is plugged in.
Risk: An electrical short circuit can increase the risk of a fire.
Fix: Owners are advised not to plug in their block heater until the vehicle is remedied. Dealers will replace the block heater, free of charge. Owners will also have a alternative option to replace engine block heater element with a threaded blanking plug, and remove the block heater electrical cord. Interim letters, notifying owners of the safety risk, were mailed December 3, 2025. Additional letters will be sent once the final remedy is available, anticipated September 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25SA4.

Essential maintenance
Critical for safety and preventing major damage
Engine Oil & Filter
Every 7,500 miReplace 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 miRotate 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 miInspect 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 miFord 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 miReplace 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 miFord 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 miF-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 miF-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 miIridium 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 miMotorcraft 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 miReplace 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.
