2021 Mercedes-Benz Sprinter
The 2021 Mercedes-Benz Sprinter is a van; 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 18 recall campaigns for this model year, which gives it a Safety Signal grade of F. Owners have filed 62 complaints, most often about the forward collision avoidance.

Filed by the manufacturer with NHTSA under the federal vehicle-identification rule and decoded from the VIN pattern — not a manufacturer press kit, so it describes one configuration rather than every trim (seen: 907 (VS30)). Figures for the trim you are looking at may differ.
Dimensions & weight

| Width (body, without mirrors) | 79.5 in |
| Height | 96.5–117.7 in |

Measured by Transport Canada for its Canadian Vehicle Specifications database, which covers the North American versions of each model — here 37 configurations: 1500 Cargo 144-IN Wb High Roof, 1500 Cargo 144-IN Wb Standard Roof, 1500 Passenger 144-IN Wb High Roof, 2500 Cargo 144-IN Wb High Roof, 2500 Cargo 144-IN Wb High Roof 4WD, 2500 Cargo 144-IN Wb Standard Roof …. 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%.

VS3UXPOBOXThese are vehicle campaigns — the ones the automaker filed against this model. NHTSA also records equipment recalls, filed by a parts maker against a component (a tyre, a child seat, an aftermarket part), and those are not listed here or counted above. nhtsa.gov/recalls shows both for a VIN.
Whether any of this applies to one specific Sprinter
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. Mercedes-Benz 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 Mercedes-Benz Sprinter, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

In owners' own words
Filed with NHTSA by the people who own these cars, one per problem area. Quoted as written, with anything identifying removed.
Mercedes Dealership is refusing to get the vehicle in to make this safety recall repair in a timely manner. I have been told that i will need to wait for over a month just to drop the vehicle off with no time frame given in terms of how long the vehicle will be gone while being repaired
This recall was issued on March 17, 2022. It has now been over 120 days since that recall was issued and the parts are not yet available. I believe the manufacturer has exceeded a reasonable amount of time for the recall repair
The Distronic Cruise Control stops working and then will start working again several times on long trips. After research it appears if the radar doesn't detect anything in front of your vehicle for an hour it thinks it is inoperable and and shuts the Distronic Cruise Control off and it cannot be reengaged.
Vehicle is unable to move apparently because of a design flaw that allows water to travel down cables into the EIS as described here and here
Fuel pump recall July 5. No resolution. Vehicle deemed unsafe per recall. Please advise. Have contacted Mercedes Benz and also local dealer. No resolution at this time. What are the next steps?
The contact owns a 2021 Mercedes-Benz Sprinter 3500. The contact stated that while driving at an undisclosed speed, the message “Driver’s Side Air Bag Deactivated” was displayed. The vehicle was taken to a dealer, where it was diagnosed, and determined that the wiring harness needed to be rewired.
Complaint counts are raw owner reports to NHTSA, not verified defects, and scale with how many were sold. Use them to spot patterns, not to rank.
Reported by Mercedes-Benz itself: 2 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 1 killed, 1 injured, as claimed, not verified — about 6.9 per 100,000 built. Every Sprinter model year, by year and system → Dated and by system, they are exhibit F of the defect dossier.

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.
Diagnostic trouble codes on file
Source: NHTSA manufacturer communications and complaintsCodes documented against this model year in the federal record. A code appearing here does not mean this vehicle will set it — it means the code is part of this nameplate-year's documented history.
| Code | What it means | Most often filed under | Where it appears |
|---|---|---|---|
| P012C | Manufacturer-defined — the meaning is set by the automaker, not the standard. | Engine | 1 owner report |
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
Source: New York State DMVIn New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Mercedes-Benz Sprinter failed the emissions check on 0.47% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 0.40% (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).
Sprinter by model year
all years, side by side →Common questions about the 2021 Sprinter
Source: EPA, NHTSA and manufacturer press kitsDoes the 2021 Mercedes-Benz Sprinter have any recalls?
NHTSA has posted 18 recall campaigns for the 2021 Mercedes-Benz Sprinter. The most serious on file is 23V876000, covering Structure. 3 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. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2021 Mercedes-Benz Sprinter?
NHTSA has not published a crash-test rating for the 2021 Mercedes-Benz Sprinter yet. On the recall record WhichTrim grades it F (51/100), which measures open and severe recalls rather than crash protection.
What are the dimensions of the 2021 Mercedes-Benz Sprinter?
Transport Canada measured it at 233.5–290.2 in long, 79.5 in wide (body, without mirrors), 96.5–117.7 in tall, on a 144.1–170.1 in wheelbase. Curb weight: 4,696–6,173 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 Mercedes-Benz Sprinter?
Owners have filed 62 complaints with NHTSA about the 2021 Mercedes-Benz Sprinter, most often about forward collision avoidance, service brakes, unspecified. Of those, 4 involved a crash, 1 reported injuries. 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 Mercedes-Benz Sprinter?
The manufacturer has filed 517 service bulletins and related communications with NHTSA for the 2021 Mercedes-Benz Sprinter, most often covering engine, electrical system, unknown or other. The most recent is dated 2026-09-29. 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 Mercedes-Benz Sprinter do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Mercedes-Benz Sprinter failed the emissions check on 0.47% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 0.40% (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.
| Data | Held | Source | What it covers — or what empty means |
|---|---|---|---|
| Fuel economy & configurations | none | EPA certification records | The EPA does not certify vehicles rated over 8,500 lb GVWR, so heavy-duty nameplates have no entry at all. |
| Emission certificates | none | EPA emission certificates | The EPA published no certificate we could match to a configuration on this page. |
| Recalls | 18 | NHTSA recall campaigns | A complete federal register: every campaign covering this model year, with severity and advisory flags. |
| Owner complaints | 62 | NHTSA complaint database | Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold. |
| Crash ratings | 3 tested | NHTSA NCAP | Only the configurations NHTSA chose to crash-test, which is never all of them. |
| Service bulletins | 517 | NHTSA manufacturer communications | Everything the manufacturer told its dealers about a defect or malfunction, short of a recall. |
| Investigations | none | NHTSA Office of Defects Investigation | No defect investigation has been opened. |
| Driver-assist crash reports | none | NHTSA Standing General Order 2021-01 | No report has been filed. Only entities named in the order report, and only crashes they hear of — so this is also what an unequipped car, or a manufacturer without telematics, looks like. |
| Specifications filed with NHTSA | 9 fields | NHTSA vPIC, decoded from VIN patterns | What the manufacturer filed under the federal VIN rule — a configuration, not the full trim ladder. |
| Measured dimensions | 7 fields | Transport Canada, Canadian Vehicle Specifications | Length, width, height, wheelbase, track and curb weight, measured on the North American versions. |
| Trims, pricing & equipment | none | Manufacturer press kit | We have not transcribed a press kit for this model year yet. This is our gap, not the manufacturer's — the one row here where an empty cell means we are behind. |

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.
