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.

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.
I have a 2018 Hyundai Kona, with approximately 42,000 miles on it. The right front passenger door began having problems sometime in 2022. When I first inquired about the door at Riverside Hyundai, I was advised that the problem might be covered under warranty. I did not have the problem diagnosed at that time.
UNKNOWN. AC stopped working. According to repair shop, alternator belt sliced through the aluminum housing tube and Freon cannot be recharged . It needs total rebuild/reroute of AC tubing as The position and location of alternator belt is too close to the aluminum housing/tubing for cooling system. This is a bad build/design.
Car antenna broke off while driving on the interstate. Possible projectile that can cause an accident. Airconditioning system in the car smells like mildew. Possible prolong exposure that can cause a health hazard. It only happens when the car starts every time
When driving at night 98 % of oncoming drivers flash their lights at me to indicate that I had forgotten to dim my lights when in fact I did not have my high beams engaged. I took this issue to the dealership which did it's best to fix the problem but was unable to correct it.
I AM requesting investigation into excess glare from LED headlights on the Kona limited model, year 2018 for those manufactured prior to june. Excessive glare originates from the LED lights and results in consistent "bright beam" flashes from on coming drivers, as they think you have your brights on.

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 Hyundai itself: 2 death-or-injury claims on this model year in its quarterly Early Warning reports to NHTSA (49 CFR 579.21): 2 injured, as claimed, not verified — about 5.3 per 100,000 built.

When owners reported it
miles, typically
Half the 24 owner reports with an odometer reading on file fall between 5,000 and 50,000 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.
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 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.

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.

Kona by model year
all years, side by side →Common questions about the 2018 Kona
Source: EPA, NHTSA and manufacturer press kitsDoes the 2018 Hyundai Kona have any recalls?
No NHTSA recall campaigns are on file for the 2018 Hyundai Kona. New campaigns appear here within a week of NHTSA posting them, and a clean sheet on a recent model year often just means the vehicle is new.
How safe is the 2018 Hyundai Kona?
NHTSA has not published a crash-test rating for the 2018 Hyundai Kona 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 2018 Hyundai Kona?
Across the 4 EPA-rated configurations of the 2018 Hyundai Kona, the best EPA combined figure is 30 mpg. Figures are the EPA's own, per configuration, and every one is listed above.
What are the dimensions of the 2018 Hyundai Kona?
Transport Canada measured it at 164.2 in long, 70.9 in wide (body, without mirrors), 59.1 in tall, on a 102.4 in wheelbase. Curb weight: 2,890–3,256 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 Hyundai Kona?
Owners have filed 75 complaints with NHTSA about the 2018 Hyundai Kona, most often about engine, unspecified, power train. Of those, 9 involved a crash, 10 a fire, 12 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 Hyundai Kona?
The EPA smog rating for the 2018 Hyundai Kona is 5 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 ULEV70, Federal Tier 3 Bin 70 — which the table above lists per configuration.
Are there service bulletins for the 2018 Hyundai Kona?
The manufacturer has filed 96 service bulletins and related communications with NHTSA for the 2018 Hyundai Kona, most often covering electrical system, equipment, power train. The most recent is dated 2026-10-08. 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 Hyundai Kona do at state inspection?
In New York’s inspection lanes over the 12 months to Oct 10, 2026, the 2018 Hyundai Kona failed the emissions check on 1.7% of first inspections — lower than the 3.0% for every 2018 model-year vehicle inspected; and the safety inspection on 2.3% (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.

| Emission certificates | 4 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. |

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.
