Air Bags:Side/Window — Inadvertent Deployment of Side Air Bags closed
On October 28, 2025, the Office of Defects Investigations (ODI) opened PE25018 to investigate complaints of inadvertent deployment of the side curtain and/or side thorax air bags. These complaints concern model year (MY) 2018-2022 Honda Odyssey vehicles manufactured by American Honda Motor Co. (Honda). Honda issued recall 26V227 on April 9, 2026, to address concerns of inadvertent side air bag deployment. In the recall filing, the company stated that “[a]s of April 2, 2026, Honda has had 130 warranty claims, 25 reports of an injury, and no reports of death related to this issue from January 24, 2017 – April 2, 2026.” Honda states that the Supplemental Restraint System (SRS) Electronic Contro

Engine — Engine failure open
The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline. The subject engine failures were analyzed as part of a Recall Query (RQ24013). It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751. Based on analysis of data from RQ24013,

Engine And Engine Cooling:Engine — No Restart After Auto Start/Stop Engages open
On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020

Engine — Engine failure closed
On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure.

Whether any of this applies to one specific Odyssey
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. Honda 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 Honda Odyssey, with what to do next. Nothing else, ever — no newsletter, no marketing, one-click unsubscribe in every message.

When owners reported it
miles, typically
Half the 263 owner reports with an odometer reading on file fall between 7,000 and 79,000 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.

Vs same age is this model year’s median for the system divided by the median of every 2018-model-year complaint about the same system, all makes: under 1× means owners of this car reported it at lower mileage. Here, owners reported earlier than same-age vehicles: electrical system (0.58×), structure (0.44×), service brakes (0.6×); later: engine (1.87×), fuel/propulsion system (1.82×), latches/locks/linkages (2.28×). Which systems go early across the whole fleet: the component study.
Across 2018–2020 model years the Honda Odyssey ranks 45 of 79 nameplates in the odometer-at-first-complaint study: owners reported problems at 1.18× the mileage of vehicles the same age (median 26,000 miles against a fleet 23,512).
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.

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.

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.

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.

Odyssey by model year
all years, side by side →Common questions about the 2018 Odyssey
Source: EPA, NHTSA and manufacturer press kitsDoes the 2018 Honda Odyssey have any recalls?
NHTSA has posted 16 recall campaigns for the 2018 Honda Odyssey, 2 of them rated critical. The most serious on file is 26V227000, covering Air Bags. Check your own VIN at nhtsa.gov/recalls; a recall applies to specific build ranges, not every car.
How safe is the 2018 Honda Odyssey?
NHTSA gave the 2018 Honda Odyssey 5 stars overall in its New Car Assessment Program tests — 5-star frontal crash, 5-star side crash, 4-star rollover. WhichTrim also grades it F (38/100) on its recall record, which is a different question from crash protection.
What is the fuel economy of the 2018 Honda Odyssey?
Across the 2 EPA-rated configurations of the 2018 Honda Odyssey, the best EPA combined figure is 22 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2018 Honda Odyssey?
Transport Canada measured it at 203.9 in long, 78.0 in wide (body, without mirrors), 67.7 in tall, on a 118.1 in wheelbase. Curb weight: 4,418–4,511 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 2018 Honda Odyssey?
Owners have filed 1007 complaints with NHTSA about the 2018 Honda Odyssey, most often about forward collision avoidance, electrical system, engine. Of those, 14 involved a crash, 3 a fire, 30 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 2018 Honda Odyssey?
The EPA smog rating for the 2018 Honda Odyssey 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 Honda Odyssey?
The manufacturer has filed 278 service bulletins and related communications with NHTSA for the 2018 Honda Odyssey, most often covering electrical system, equipment, engine. The most recent is dated 2025-02-19. 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 Honda Odyssey do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2018 Honda Odyssey failed the emissions check on 4.1% of first inspections — higher than the 3.0% for every 2018 model-year vehicle inspected; and the safety inspection on 1.9% (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.

| Service bulletins | 278 | NHTSA manufacturer communications | Everything the manufacturer told its dealers about a defect or malfunction, short of a recall. |
| Investigations | 4 | NHTSA Office of Defects Investigation | Open and closed defect investigations, with the agency's own narrative. |
| Driver-assist crash reports | 2 | NHTSA Standing General Order 2021-01 | Crashes the manufacturer or operator reported with a Level 2 or automated-driving system engaged. Notices, filed before verification; not comparable across makes. |
| Specifications filed with NHTSA | 13 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.
