The 2021 Ford F-250 Super Duty is a pickup truck; vehicles over 8,500 lb GVWR are not certified for fuel economy by the EPA, so this page is built from NHTSA's recall, complaint and investigation records. NHTSA lists 12 recall campaigns for this model year, 1 rated critical, which gives it a Safety Signal grade of F. Owners have filed 167 complaints, most often about the fuel/propulsion system. NHTSA crash-tested it at 5 stars overall.

Where a range is shown, those versions differ. Width is the body without mirrors, which is why it can read narrower than a brochure figure. Before we used it we checked it against the US manufacturer press kits we hold (27 Sep 2026): wheelbase agreed within 1% on every vehicle we could compare, length on 98%, and the curb weight fell inside the manufacturer's range on 96%.

NHTSA defect investigations

Fuel System, Other:Fuel Filter — Sogefi Secondary Diesel Fuel Filter Leak open

The Office of Defect Investigations (ODI) has received 27 complaints alleging diesel fuel leaks due to a fracture in the secondary fuel filter housing in model year (MY) 2015-2021 Ford Motor Company (Ford) F-250, 350, 450, and 550 Super Duty vehicles equipped with 6.7L diesel engines. Of these complaints, 12 describe an engine compartment fire. The proximity of the secondary fuel filter to high heat sources creates a potential for autoignition thermal events and fires. ODI has contacted the vehicle manufacturer, Ford, and the filter manufacturer, Allevard Sogefi USA (Sogefi), and learned that the low-pressure fuel system is capable of a maximum operating pressure of 8.5 Bar, while the second

Whether any of this applies to one specific F-250 Super Duty

A campaign covers a build range, not a model year, so two identical-looking cars from 2021 can differ. Both of these check a VIN against the manufacturer’s own list, free, in about ten seconds. Ford publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.

Hear about a recall before the letter does

The manufacturer’s letter is the last step of a recall: it has up to 60 days after filing to mail owners, at the address on the registration. We email you the day NHTSA posts a recall on the 2021 Ford F-250 Super Duty, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

Half the 47 owner reports with an odometer reading on file fall between 31,000 and 77,000 miles. That is when problems get reported, which is not the same as when they start — and not a failure rate, because nobody knows how many of these cars never had a problem at all.

Vs same age is this model year’s median for the system divided by the median of every 2021-model-year complaint about the same system, all makes: under 1× means owners of this car reported it at lower mileage. Here, owners reported later: fuel/propulsion system (2.07×). Which systems go early across the whole fleet: the component study.

Across 2018–2021 model years the Ford F-250 Super Duty ranks 52 of 79 nameplates in the odometer-at-first-complaint study: owners reported problems at 1.38× the mileage of vehicles the same age (median 25,000 miles against a fleet 23,512).

Odometer readings as filed by owners with NHTSA. Readings under 100 or over 400,000 miles are dropped as data entry rather than history, and a component needs at least 12 readings before a median is shown for it.

Workshop Manual (WSM),

A service bulletin is the manufacturer telling its dealers how to diagnose or repair a known condition. It is not a recall, not a finding that the vehicle is defective, and the work is not automatically free — though a bulletin is often what a dealer works from when you describe a symptom, so quoting the document number can save a diagnosis. The count is every communication filed; the list shows the most recent, one entry per campaign, because a single campaign is usually filed as several documents on the same day. The summaries are NHTSA's; the full documents come from the manufacturer.

Generic codes (the second character is 0 or 2) mean the same thing on every vehicle sold in the United States. Manufacturer-specific codes (1 or 3) mean whatever the automaker assigned, and no honest source can define them for you — which is why the ones here carry the evidence instead of a definition. A code is a link when enough separate federal documents name it across the catalogue to be worth a page of its own; the rest are listed here, where the vehicle is the context that makes them mean something.

At the New York inspection station

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Ford F-250 Super Duty failed the emissions check on 0.69% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 2.4% (every 2021 vehicle: 1.5%).

New York’s emissions test on these model years is an on-board diagnostics check: it fails a car whose check-engine light is on or whose self-tests have not finished. First inspections only, so a car that failed and came back is counted once; private and special plates, not taxis, livery or commercial plates. A rate appears only where at least 200 inspections stand behind it. “Every 2021 vehicle” is every 2021 model-year car, SUV and pickup inspected in the same window, all makes. This is the state’s record of test results, not a reliability score by itself. Source: New York State Department of Motor Vehicles, Vehicle Inspections (data.ny.gov, Open NY terms).

Common questions about the 2021 F-250 Super Duty

Source: EPA, NHTSA and manufacturer press kits

Does the 2021 Ford F-250 Super Duty have any recalls?

NHTSA has posted 12 recall campaigns for the 2021 Ford F-250 Super Duty, 1 of them rated critical. The most serious on file is 25V626000, covering Steering. 2 of them were filed with no repair available at the time — NHTSA's file records what the manufacturer had in hand on the filing date, not what exists today. 1 campaign is phased, so the repair reached some model years before others. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2021 Ford F-250 Super Duty?

NHTSA gave the 2021 Ford F-250 Super Duty 5 stars overall in its New Car Assessment Program tests — 5-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it F (49/100) on its recall record, which is a different question from crash protection.

What are the dimensions of the 2021 Ford F-250 Super Duty?

Transport Canada measured it at 229.5–263.8 in long, 79.9 in wide (body, without mirrors), 78.0–81.5 in tall, on a 141.7–176.0 in wheelbase. Curb weight: 5,684–6,695 lb depending on configuration. Those are its measurements of the North American versions; every figure is in the table above.

What do owners complain about on the 2021 Ford F-250 Super Duty?

Owners have filed 167 complaints with NHTSA about the 2021 Ford F-250 Super Duty, most often about fuel/propulsion system, power train, suspension. Of those, 3 involved a crash. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.

Are there service bulletins for the 2021 Ford F-250 Super Duty?

The manufacturer has filed 242 service bulletins and related communications with NHTSA for the 2021 Ford F-250 Super Duty, most often covering power train, electrical system, engine. The most recent is dated 2026-10-06. A bulletin is not a recall: it is the repair procedure a manufacturer sends its dealers for a condition it knows about, and the work is not automatically paid for. It is still worth knowing — if the symptom matches, quoting the bulletin number at the service desk can save a diagnosis. The document numbers and summaries are listed above.

How does the 2021 Ford F-250 Super Duty do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Ford F-250 Super Duty failed the emissions check on 0.69% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 2.4% (every 2021 vehicle: 1.5%). The figures are New York State DMV’s own inspection records, first inspections only, and the table above sets each one against every vehicle of the same model year.

What we hold, and what an empty row means

Paid vehicle-history reports will not tell you the difference between “nothing happened to this car” and “we never received that record” — both of the big two say as much in their own help pages. Most of what is on this page comes from complete federal registers, so we can tell you which is which, row by row.

Sources & method

Safety Signal starts every model-year at 100 and subtracts points per open NHTSA recall campaign by severity: critical 15 (fire risk, park-outside or do-not-drive advisories), high 8 (brakes, steering, airbags, loss of drive power, structure, battery), moderate 6, minor 3 (software, labels, lighting fixed by an update). The most serious recall counts in full and each further one counts 85% of the one before, because a vehicle sold in millions is recalled more often than a rare one without being more dangerous — and because a flat subtraction bottomed the scale out, scoring a vehicle with 22 recalls within a point of one with six. A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, otherwise F. Read it as what it counts: recall campaigns on the federal record, weighted by severity. The damping reduces the sales bias by roughly 40% but does not remove it: like our complaint counts, this is not normalized by how many were sold, so a best-seller still scores somewhat worse than an obscure model with the same real risk. NHTSA crash ratings, do-not-drive and park-outside advisories, and the crash, fire, injury and death counts in owner complaints are reported separately on every page and never blended into the letter — a vehicle can hold five stars and a poor letter at once, and where that happens we say so rather than leave you to notice. Because the scale subtracts from a clean sheet, a model year too new to have been recalled, complained about or bulletined scores full marks on an empty record; we label those grades provisional rather than present them as earned.

EPA figures come from fueleconomy.gov vehicle records. Recalls, complaints, investigations and crash ratings come from NHTSA's public flat files, refreshed nightly.
