The 2021 Ford F-450 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, 2 rated critical, which gives it a Safety Signal grade of F. Owners have filed 18 complaints, most often about the electrical system.

Measured by Transport Canada for its Canadian Vehicle Specifications database, which covers the North American versions of each model — here one configuration: SD P/U Crew Cab L/Box Drw 4X4. 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

Besides the recall remedy launched in January 2020, Ford also implemented a production update in November 2019.  At the time of the RQ opening, ODI had received eleven (11) Vehicle Owner Questionnaires (VOQs). ODI sent an Information Request (IR) to Ford in February 2021. In numerous meetings after receiving their IR response, Ford highlighted the drop in claims since the recall and production update and communicated how they were unable to verify the owners’ complaints or

Whether any of this applies to one specific F-450 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.

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.

Common questions about the 2021 F-450 Super Duty

Source: EPA, NHTSA and manufacturer press kits

Does the 2021 Ford F-450 Super Duty have any recalls?

NHTSA has posted 12 recall campaigns for the 2021 Ford F-450 Super Duty, 2 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. There is an active do not drive advisory — act on it before driving. 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-450 Super Duty?

NHTSA has not published a crash-test rating for the 2021 Ford F-450 Super Duty yet. On the recall record WhichTrim grades it F (43/100), which measures open and severe recalls rather than crash protection.

What are the dimensions of the 2021 Ford F-450 Super Duty?

Transport Canada measured it at 263.8 in long, 79.9 in wide (body, without mirrors), 81.1 in tall, on a 176.0 in wheelbase. Curb weight: 8,589 lb. 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-450 Super Duty?

Owners have filed 18 complaints with NHTSA about the 2021 Ford F-450 Super Duty, most often about electrical system, power train, structure. Of those, 1 a fire. 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-450 Super Duty?

The manufacturer has filed 237 service bulletins and related communications with NHTSA for the 2021 Ford F-450 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.

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.
