Emissions & certification
Source: EPA emission certificates| Configuration | Smog rating | Emission standard | Where it can be sold new | SmartWay |
|---|---|---|---|---|
| Clarity Plug-in Hybrid | 8 / 10 | California LEV-III SULEV20 / Federal Tier 3 Bin 20 | All 50 states (federal, all altitudes); California and states following California standards | SmartWay Elite |
| Clarity FCV | 10 / 10 | Federal Tier 3 Bin 0 / California ZEV | All 50 states (federal, all altitudes); California and states following California standards | SmartWay Elite |
Certified for all fifty states, so it can be registered new anywhere in the U.S.
The smog rating scores tailpipe pollutants other than greenhouse gases, 1 (worst) to 10 (best), and is comparable only within a model year. The standard is the federal bin or California tier the configuration was certified to. Both come from the EPA certificate behind the window sticker.

NHTSA defect investigations
Electrical System:Propulsion System — Pedestrian alert sounds closed
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021. On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject mat

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.
Component/System that Failed: The air conditioning system in my 2021 Honda Clarity Touring Plug-in Hybrid has failed — specifically, the AC evaporator, which no longer allows the car to blow out cool air. The part is still in the vehicle and is available for inspection upon request.
Received multiple warning alerts that adaptive cruise control, automatic emergency braking, forward collision warning, and Lane Departure/Keeping were not working while driving car. Took car to Honda dealership for repair and was told that this was a "DTC U3000-49" multipurpose camera unit failure.
I was reversing in order to go up a driveway at an Airbnb where my husband and I had been staying. The bottom of the car is low to the ground, and it was difficult to clear a rise at the bottom of the driveway.
The engine revs a lot when battery charge is low the engine and transmision gets very loud car has only 500 miles and is doing it constant

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.

|---|---|---|---|
| P1F86 | Manufacturer-defined — the meaning is set by the automaker, not the standard. | Engine | 2 bulletins |
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.

Clarity by model year
all years, side by side →Common questions about the 2021 Clarity
Source: EPA, NHTSA and manufacturer press kitsDoes the 2021 Honda Clarity have any recalls?

How safe is the 2021 Honda Clarity?
NHTSA has not published a crash-test rating for the 2021 Honda Clarity yet. On the recall record WhichTrim grades it A (100/100), which measures open and severe recalls rather than crash protection.
What is the fuel economy of the 2021 Honda Clarity?
Across the 2 EPA-rated configurations of the 2021 Honda Clarity, the best EPA combined figure is 68 mpg (MPGe on the electrified versions). Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2021 Honda Clarity?
Transport Canada measured it at 192.9 in long, 74.8 in wide (body, without mirrors), 58.3 in tall, on a 108.3 in wheelbase. Curb weight: 4,063 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 Honda Clarity?
Owners have filed 4 complaints with NHTSA about the 2021 Honda Clarity, most often about forward collision avoidance, engine, power train. Of those, 1 involved a crash. Complaints are unverified owner reports, so treat the pattern as a signal and the individual report as an anecdote.
How clean is the 2021 Honda Clarity?
The EPA smog rating for the 2021 Honda Clarity runs 8 to 10 out of 10 across its configurations. That score covers tailpipe pollutants other than greenhouse gases, and it only compares vehicles within the same model year. It is certified for all fifty states, so it can be registered new anywhere in the U.S. Its configurations were certified to different standards — California LEV-III SULEV20, California ZEV, Federal Tier 3 Bin 0, Federal Tier 3 Bin 20 — which the table above lists per configuration.
Are there service bulletins for the 2021 Honda Clarity?
The manufacturer has filed 9 service bulletins and related communications with NHTSA for the 2021 Honda Clarity, most often covering air bags, seats, engine. The most recent is dated 2022-01-29. 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.
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.

|---|---|---|---|
| Fuel economy & configurations | 2 configurations | EPA certification records | Every configuration the EPA certified for sale, with its own test figures. |
| Emission certificates | 2 configurations | EPA emission certificates | Smog rating, standard and the sales area that decides where the car can be sold new. |
| Recalls | none | NHTSA recall campaigns | No campaign has been filed. Because the register is complete, an empty row here means there is nothing to find — not that we are missing it. |
| Owner complaints | 4 | NHTSA complaint database | Also complete, but unverified: these are reports owners filed, not findings. Counts scale with how many were sold. |
| Crash ratings | none | NHTSA NCAP | NHTSA has not tested this model year. Cars are selected for testing, so untested is not unsafe. |

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.
