14th gen (P702) · 2021–present
2.7 EcoBoost V6 · 325 hp · 3.3 Ti-VCT V6 · 290 hp · 3.5 EcoBoost V6 · 400 hp · 3.5 PowerBoost hybrid · 430 hp · 5.0 V8 (Coyote) · 400 hp
Known problems
- Worth watching
10-speed automatic shift refinement (early builds)
Symptoms: occasional harsh or hesitant gear changes and a clunk when shifting into gear on early 2021 trucks
What to do: Some early 14th-gen trucks show the same 10-speed harshness as the prior generation. A dealer software update and adaptive relearn usually improves it; have it done under warranty.
- Worth watching usually from 50,000 mi (80,000 km)
3.5 EcoBoost cam phaser rattle (carryover)
Symptoms: a short metallic rattle on cold start-up on the 3.5 EcoBoost, mostly at higher mileage
What to do: The cam-phaser/timing-chain rattle that affected earlier 3.5 EcoBoost engines can still appear on higher-mileage trucks. Have a persistent cold-start rattle inspected and keep oil changes current with the correct specification.
- Good to know
5.0 V8 oil consumption (watch)
Symptoms: oil level falling between changes with no visible leak
What to do: The 5.0 V8's tendency to use oil can carry over; check the dipstick between services and keep it topped up. Have a dealer confirm the latest engine-control calibration is installed.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 7,000 mi (12,000 km) or 12 months | follow the oil-life monitor; halve for towing, heavy loads or short-trip use |
| Cabin filter | every 19,000 mi (30,000 km) | — |
| Air filter | every 28,000 mi (45,000 km) | — |
| Spark plugs | every 62,000 mi (100,000 km) | shorter (~60k km) on the turbo EcoBoost engines; ~160k km on the 5.0 V8 |
| 10-speed automatic fluid (10R80) important | every 93,000 mi (150,000 km) | service earlier if used for towing or in severe conditions |
| Brake fluid important | every 36 months | — |

Known problems
- Worth watching usually from 0 mi (0 km)
10-speed automatic (10R80) harsh or erratic shifting
Symptoms: clunky, jerky or delayed gear changes; a clunk on start-off or when shifting into gear; occasional hesitation
What to do: If the 10-speed shifts harshly or clunks, start with the dealer software update and an adaptive relearn; a transmission fluid service can help. Persistent cases sometimes need valve-body work, so address it while the warranty applies.
- Worth watching
3.5 EcoBoost intercooler condensation stumble
Symptoms: a brief misfire, shudder or hesitation under hard acceleration in cold, humid or damp conditions
What to do: On early (2015-2016) 3.5 EcoBoost trucks, condensation can pool in the intercooler and cause a stumble under wide-open throttle in humid weather. Owners address it with updated calibration or an intercooler drain/relocation; it is a driveability nuisance rather than a failure.
- Worth watching usually from 19,000 mi (30,000 km)
5.0 V8 (Coyote) oil consumption
Symptoms: oil level dropping noticeably between changes with no visible leak; occasional low-oil warning before the next service
What to do: On 2018-2020 trucks with the third-generation 5.0 V8, check the dipstick regularly and top up as needed. Ask a dealer about the engine-control software update that reduces the consumption, and keep documentation in case it needs escalation.
- Worth watching usually 50,000–124,000 mi (80,000–200,000 km)
3.5 EcoBoost cam phaser & timing chain rattle
Symptoms: a few seconds of metallic rattle on cold start-up, often fading once warm; may set variable cam timing fault codes as it worsens
What to do: A brief cold-start rattle on the 3.5 EcoBoost points to worn cam phasers and a stretched timing chain. Have it inspected before it progresses; the usual fix replaces the phasers and chain together. Keep oil changes on schedule with the correct specification to slow wear.

| Timing chain inspection | — | all engines are chain-driven — inspect for cold-start rattle rather than on a fixed interval |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
