2021 Hyundai Sonata: Recalls and Reported Problems
Every NHTSA safety recall recorded for this model year, what owners report most often, and how to check whether one specific vehicle still has open work.
Two identical Sonatas can differ entirely: one may have had every recall repaired, the other none.
NHTSA lists 4 safety recalls for the 2021 Hyundai Sonata, alongside 129 owner complaints filed with the agency, most often about engine. Recall repairs are performed free of charge by a franchised dealer, with no expiry on safety recalls. A recall applies to a production range, so check the specific VIN — a previous owner may already have had the work done.

Recall campaigns for the 2021 Hyundai Sonata
Each campaign below is an official NHTSA record. The remedy is performed free of charge by a franchised dealer, and safety recalls never expire — but a campaign covers a production range, so only a VIN lookup confirms whether a particular vehicle is included and whether the work is still outstanding.
| Campaign | Component | Issue |
|---|---|---|
| 21V524000 | FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS | Hyundai Motor America (Hyundai) is recalling certain 2021-2022 Santa Fe and Sonata vehicles equipped with 2.5L turbocharged engines. Fuel may leak at the pipe connection between the high-pressure fuel pump and fuel rail. |
| 21V00M000 | VISIBILITY:WINDSHIELD | Hyundai Motor America (Hyundai) is recalling certain 2020-2021 Santa Fe, 2021 Sonata, and Elantra vehicles. During manufacturing, the windshield may not have been properly bonded to the vehicle, allowing it to detach in a crash. |
| 22V746000 | POWER TRAIN:AUTOMATIC TRANSMISSION | Hyundai Motor Company (Hyundai) is recalling certain 2021-2022 Santa Fe, Sonata, Veloster N, 2022 Santa Cruz, Elantra N, and Kona N vehicles.

| 25V796000 | FUEL SYSTEM, GASOLINE | Hyundai Motor America (Hyundai) is recalling certain 2020-2023 Sonata vehicles. A damaged check valve can allow air to enter the fuel tank, causing it to expand and contact hot exhaust components, melting the tank. |
How to check one specific Sonata
- Copy the 17-character VIN from the windshield or driver-door label — not from the listing.
- Run it through NHTSA’s free recall lookup to see open campaigns for that exact vehicle.
- Ask the seller for repair documentation on any campaign that shows as completed.
- Check title, odometer, and total-loss history separately; recalls say nothing about a vehicle’s past.
- Book an independent pre-purchase inspection focused on the systems owners report most.
What this data cannot tell you
- Whether a specific vehicle is included in a campaign, or whether its recall work was completed — only a VIN lookup answers that.
- Whether a complaint is accurate. NHTSA publishes owner reports without verifying them.
- How reliable the model is overall: complaint volume tracks how many vehicles were sold as much as how they hold up.
- Anything about title brands, accident history, odometer records, or liens on an individual vehicle.
