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 ILX

A campaign covers a build range, not a model year, so two identical-looking cars from 2018 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.

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 2018 Acura ILX, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

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.

At the New York inspection station

Source: New York State DMV

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2018 Acura ILX failed the emissions check on 2.4% of first inspections — lower than the 3.0% for every 2018 model-year vehicle inspected; and the safety inspection on 1.6% (every 2018 vehicle: 1.9%).

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 2018 vehicle” is every 2018 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 2018 ILX

Source: EPA, NHTSA and manufacturer press kits

Does the 2018 Acura ILX have any recalls?

NHTSA has posted 4 recall campaigns for the 2018 Acura ILX. The most serious on file is 25V859000, covering Service Brakes, Hydraulic. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.

How safe is the 2018 Acura ILX?

NHTSA gave the 2018 Acura ILX 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 (76/100) on its recall record, which is a different question from crash protection.

What is the fuel economy of the 2018 Acura ILX?

For the 2018 Acura ILX, the best EPA combined figure is 29 mpg. Figures are the EPA's own, per configuration, and every one is listed above.

What are the dimensions of the 2018 Acura ILX?

Transport Canada measured it at 181.9 in long, 70.9 in wide (body, without mirrors), 55.5 in tall, on a 105.1 in wheelbase. Curb weight: 3,120 lb. Those are its measurements of the North American versions; every figure is in the table above.

What do owners complain about on the 2018 Acura ILX?

Owners have filed 23 complaints with NHTSA about the 2018 Acura ILX, most often about fuel/propulsion system, electrical system, engine. Of those, 2 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 2018 Acura ILX?

The EPA smog rating for the 2018 Acura ILX is 3 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 ULEV125, Federal Tier 3 Bin 125 — which the table above lists per configuration.

Are there service bulletins for the 2018 Acura ILX?

The manufacturer has filed 68 service bulletins and related communications with NHTSA for the 2018 Acura ILX, most often covering structure, equipment, suspension. The most recent is dated 2022-01-22. 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 2018 Acura ILX do at state inspection?

In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2018 Acura ILX failed the emissions check on 2.4% of first inspections — lower than the 3.0% for every 2018 model-year vehicle inspected; and the safety inspection on 1.6% (every 2018 vehicle: 1.9%). 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.
