The 2021 Ford F-150 belongs to the 14th generation (2021-present), built with 2.7L EcoBoost, 3.5L EcoBoost, 5.0L V8, or the 3.5L PowerBoost full hybrid. It takes 5W-30 full synthetic on most of the range. Oil changes run 10,000 miles with the oil life monitor. This is the first model year of that generation, so it is the build most likely to carry early-production quirks and the most likely to have accumulated technical service bulletins.
A 2021 Ford F-150 is 5 years old in 2026, which at an average 12,000 miles a year puts it around 60,000 miles - the interval that decides its future. At roughly 60,000 miles the bigger fluids come due - transmission, differential, coolant - and this is the window that separates vehicles that reach 200,000 miles from those that do not. Deferring here is what produces expensive failures later. On that mileage estimate it should already have had transmission or CVT fluid, differential fluid and brake fluid at 60,000 miles, and the next milestone is 90,000 miles - a second transmission service, suspension inspection and belts - roughly 2.5 years away at average use.
The fault most worth knowing about on this generation is Cam phaser concerns carried over on the 5.0L, though improved from the previous generation. Owners also report Early-build 2021 models had a run of software-related electrical complaints; and EcoBoost oil dilution persists on short-trip cold-climate use. None of these are certainties on any individual vehicle - they are the patterns worth checking for when you buy or when a symptom appears.

| Interval | Service |
|---|---|
| Every 7,500 mi (or IOLM) | Oil & filter change - use the grade listed for your engine and model year above (it is not the same across generations: the 5.0L V8 takes 5W-20 through 2020 and 5W-30 from 2021), Tire rotation, Inspect belts, hoses, brakes, Check fluid levels |
| Every 20,000 mi | Replace cabin air filter, Inspect brake pads & rotors, Inspect suspension components, Check 4WD transfer case fluid (4WD models) |
| Every 30,000 mi | Replace engine air filter, Inspect coolant condition, Inspect drive belts |
| Every 60,000 mi | 10R80/6R80 transmission fluid service (severe duty), Replace brake fluid, Inspect rear axle fluid (4WD) |
| Every 100,000 mi | Iridium spark plug replacement, Coolant flush & refill, Replace serpentine belt, PCV valve inspection |
| Every 150,000 mi | 10R80 transmission fluid service (normal duty), Inspect water pump, Full driveline inspection |
The table above is indexed by service interval. This is the same schedule indexed by odometer reading, for when you know your mileage and want the list. If your odometer sits between these figures, work back to the last one you passed and catch up anything skipped.
| Odometer | Service due |
|---|---|
| 30,000 mi (48,000 km) | Oil & filter change - use the grade listed for your engine and model year above (it is not the same across generations: the 5.0L V8 takes 5W-20 through 2020 and 5W-30 from 2021), Tire rotation, Inspect belts, hoses, brakes, Check fluid levels, Replace engine air filter, Inspect coolant condition, Inspect drive belts. |
| 60,000 mi (97,000 km) | Oil & filter change - use the grade listed for your engine and model year above (it is not the same across generations: the 5.0L V8 takes 5W-20 through 2020 and 5W-30 from 2021), Tire rotation, Inspect belts, hoses, brakes, Check fluid levels, Replace cabin air filter, Inspect brake pads & rotors, Inspect suspension components, Check 4WD transfer case fluid (4WD models), Replace engine air filter, Inspect coolant condition, Inspect drive belts, 10R80/6R80 transmission fluid service (severe duty), Replace brake fluid, Inspect rear axle fluid (4WD). |
| 100,000 mi (161,000 km) | Replace cabin air filter, Inspect brake pads & rotors, Inspect suspension components, Check 4WD transfer case fluid (4WD models), Iridium spark plug replacement, Coolant flush & refill, Replace serpentine belt, PCV valve inspection. The every-7,500 mi service runs on its own cycle - the nearest fall at 97,500 and 105,000 miles. |
| 120,000 mi (193,000 km) | Same as the 60,000 mi service. |
| 150,000 mi (241,000 km) | Oil & filter change - use the grade listed for your engine and model year above (it is not the same across generations: the 5.0L V8 takes 5W-20 through 2020 and 5W-30 from 2021), Tire rotation, Inspect belts, hoses, brakes, Check fluid levels, Replace engine air filter, Inspect coolant condition, Inspect drive belts, 10R80 transmission fluid service (normal duty), Inspect water pump, Full driveline inspection. |
| 200,000 mi (322,000 km) | Same as the 100,000 mi service. The every-7,500 mi service runs on its own cycle - the nearest fall at 195,000 and 202,500 miles. |

The 2021 Ford F-150 has 28 safety recalls on record with NHTSA, affecting the power train, visibility, air bags (as of 2026-07-09). Recall repairs are free at any dealer.
Maintenance keeps these away, but when the dash does light up these are the codes this vehicle throws most often - each with what it means and what the repair actually costs.
