2020–2023 Hyundai Sonata: fuel system, gasoline recall
A melted fuel tank can leak, increasing the risk of a fire.
What was reported
Source: manufacturer filing, 49 CFR Part 573Reported to NHTSA Nov 17, 2025 by Hyundai Motor America, owners notified Mar 9, 2026.
What that means, in plain English
Source: WhichTrim's reading of the filing above — not NHTSA's wordingA melted fuel tank that can leak and ignite constitutes a fire/thermal event risk, placing this in the critical category despite the hedged causal chain (damaged check valve → tank expansion → contact with exhaust → melt → leak → fire).
Written for us by a language model from the manufacturer's filed text, which is quoted in full above. Where the two differ, the filing is the record and this is only our summary of it.

The advisory, as filed: “As required by federal law, dealers must not deliver new vehicles for sale or for lease to customers until all open recalls have been performed.”
Read from NHTSA’s copy of the manufacturer’s dealer documents (manufacturer campaign 286). The procedure itself is in the bulletin; a franchised dealer has the current copy on the manufacturer’s portal, and that copy governs. Working a lot or a fleet? Recall Watch carries this line on every VIN it checks: remedy status, hours, stop-sale.
Which vehicles are covered
Source: NHTSA campaign 25V796000Vehicles built Oct 22, 2019 to Oct 7, 2023 — a VIN outside that window is not part of this campaign even if the year, make and model match.
| Model year | Class | Safety Signal | Recalls on file |
|---|---|---|---|
| 2020 Hyundai Sonata | Large Sedan | C | 4 |
| 2021 Hyundai Sonata | Large Sedan | D | 4 |
| 2022 Hyundai Sonata | Large Sedan | D | 3 |
| 2023 Hyundai Sonata | Large Sedan | C | 2 |
Those are the model years inside WhichTrim's range, 2016 onward. The campaign may cover others outside it, and the only thing that settles whether one specific vehicle is included is its VIN.
How much of it has been fixed
Source: manufacturer quarterly report, 49 CFR 573.7of the campaign
3 quarters into the six-quarter reporting window, and still climbing.
This is the manufacturer's own cumulative count of vehicles it has inspected and repaired, divided by the vehicles the campaign covers. It files that count with NHTSA every quarter for six consecutive quarters, starting from the quarter in which owners were told a remedy was ready, and then the obligation ends — so a figure on an older campaign is where the count stopped, not where it stands today.
It rarely reaches 100%, and not because the work was not done. The same report asks manufacturers to count vehicles they could not reach at all — exported, stolen, scrapped, or simply never located — and those stay in the denominator. A low number means a lot of these vehicles are still out there unrepaired; it does not tell you which ones.

Common questions
Source: NHTSA, 49 CFR Part 573Is 286 the same recall as 25V796000?
Yes. 286 is the number Hyundai Motor America uses for this campaign in its own paperwork and in the letter it sends owners. 25V796000 is the number NHTSA files it under. One recall, two references — dealers and service departments generally quote the manufacturer's.
Does this recall repair cost anything?
No. Federal law requires the manufacturer to remedy a safety defect or a compliance failure at no charge, for vehicles up to 15 years old measured from the date of first sale. A dealer that asks you to pay for a recall repair is in the wrong.
How do I know whether my vehicle is included?
By VIN, not by model year. This campaign covers vehicles built Oct 22, 2019 to Oct 7, 2023. The manufacturer files a build range with NHTSA and only vehicles inside it are covered, so two identical-looking cars from the same year can differ. NHTSA's own lookup checks a VIN against the manufacturer's list.
What if the repair is not available yet?
It happens, and often. Manufacturers must notify owners when a defect is found even if the parts or the software are not ready, then notify them a second time once the remedy exists. The remedy filed for this campaign is described above.
What did the manufacturer say was wrong?
The problem, risk and fix quoted on this page are the manufacturer's own words as filed with NHTSA under 49 CFR Part 573. WhichTrim does not paraphrase them.
Who started this recall?
NHTSA's record credits the manufacturer. A recall can begin with the manufacturer's own testing, with a defect investigation, or with a compliance test against a Federal Motor Vehicle Safety Standard.
