NHTSA's VIN data lists these trims for the 2021 Kona. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 146 complaints with NHTSA about the 2021 Kona. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 3 recall campaigns for the 2021 Kona over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Hyundai Motor America (Hyundai) is recalling certain 2021 Kona EV vehicles. The Electric Power Control Unit (EPCU) may have been improperly sealed and may leak coolant internally.
Risk: Coolant contacting the EPCU circuit board may cause a loss of drive power, increasing the risk of a crash.
Remedy: Dealers will inspect and replace the EPCU, as necessary, free of charge. Owner notification letters were mailed March 22, 2023. A second notice will be sent once the final remedy is available. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 239.
Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Elantra, 2019-2021 Kona and Veloster vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which could result in engine damage.
Risk: A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.
Remedy: Dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software. Owner notification letters were mailed August 24, 2021. Owners may contact Hyundai customer service at 1-855-371-9460.
Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Nexo Fuel Cell and 2019-2021 Kona Electric vehicles. The Integrated Electronic Brake (IEB) system may detect an abnormal sensor signal and as a result, may significantly reduce braking performance.
Risk: Reduced braking power could lengthen the distance required to stop the vehicle, increasing the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will update the IEB software, free of charge. The recall began January 25, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 199.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
