These 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 RDX

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. Acura publishes its own lookup because federal rule 49 CFR 573.15 requires it to, and to keep it current to within seven days.

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 Acura RDX, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

When owners reported it

Reported at 30k

miles, typically

Half the 13 owner reports with an odometer reading on file fall between 3,000 and 60,000 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.

Too few readings for a curve — the 13 on file: 5 under 10k, 1 10k–20k, 1 30k–40k, 1 40k–50k, 1 50k–60k, 2 60k–70k, 1 70k–80k, 1 100k–150k.

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.

Honda (American Honda Motor Co.) report 62-2339 Feb 2022 NHTSA SGO filing

A report under the General Order is a notice the manufacturer or operator must file within days of hearing of a crash in which a Level 2 driver-assist or automated-driving system was engaged within 30 seconds of impact. It is filed before anything is verified, and entities with telematics hear of far more crashes than entities that rely on complaints, so counts say as much about the reporting as about the car and are not comparable across makes.

Service Bulletin - A coaxial cable terminal was not manufactured to proper specifications. An improperly manufactured terminal may lead to poor communication in the media-oriented system (MOST) bus network which can potentially affect the audio sound quality.

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 complaints

Codes 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
P0087 P0087 on Acura →	Fuel rail pressure is below what the system commanded.	Electrical System · Fuel pump →	6 bulletins
P061B P061B on Acura →	Manufacturer-defined — the meaning is set by the automaker, not the standard.	Engine	2 bulletins · 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.

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 RDX

Source: EPA, NHTSA and manufacturer press kits

Does the 2021 Acura RDX have any recalls?

NHTSA has posted 3 recall campaigns for the 2021 Acura RDX. The most serious on file is 26V332000, covering Air Bags. 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 Acura RDX?

NHTSA gave the 2021 Acura RDX 5 stars overall in its New Car Assessment Program tests — 4-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it C (79/100) on its recall record, which is a different question from crash protection.

What is the fuel economy of the 2021 Acura RDX?

Across the 4 EPA-rated configurations of the 2021 Acura RDX, the best EPA combined figure is 24 mpg. Figures are the EPA's own, per configuration, and every one is listed above.

What do owners complain about on the 2021 Acura RDX?

Owners have filed 117 complaints with NHTSA about the 2021 Acura RDX, most often about unspecified, engine, service brakes. Of those, 3 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.

How clean is the 2021 Acura RDX?

The EPA smog rating for the 2021 Acura RDX is 6 out of 10. 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 ULEV50, Federal Tier 3 Bin 50 — which the table above lists per configuration.

Are there service bulletins for the 2021 Acura RDX?

The manufacturer has filed 194 service bulletins and related communications with NHTSA for the 2021 Acura RDX, most often covering visibility/wiper, electrical system, structure. The most recent is dated 2026-05-18. 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 Acura RDX do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2021 Acura RDX failed the emissions check on 0.73% of first inspections — lower than the 1.9% for every 2021 model-year vehicle inspected; and the safety inspection on 0.90% (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.

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. Trim-level specifications and pricing are transcribed from the manufacturer's official press kit; every value carries its source in the data file.
