Engine Knocking and Detonation
Owners report a knocking or pinging noise during acceleration, particularly noticeable after refueling. The knocking is often related to improper combustion and can indicate potential engine damage if not addressed. The issue has been documented across multiple 2022 Kona vehicles with the 2.0L engine.
Hyundai issued TSB 22-01-001 addressing engine knocking noises during acceleration. Dealers will inspect the engine for faulty components and replace them as needed. Using the manufacturer-recommended 87 octane or higher fuel is important. In severe cases, engine internals may need replacement.

On 2018-2022 Kona vehicles equipped with the 2.0L engine and AWD, the transfer case pinion oil seal can overheat, causing oil leaks and a burning oil smell. Owners may notice oil spots under the rear of the vehicle or smell burning oil during and after driving.
Hyundai released a TSB addressing the transfer case oil seal issue. Dealers will replace the pinion oil seal and clean any leaked oil. The repair is covered under the powertrain warranty.

Certain 2022 Kona vehicles may develop a slight coolant leak at the radiator. Owners may notice a slow drop in coolant level, a sweet smell from the engine bay, or coolant puddles under the vehicle. If not addressed, the leak can lead to overheating.
Hyundai released a TSB providing inspection and radiator replacement procedures. Dealers will pressure test the cooling system, identify the leak source, and replace the radiator if necessary. The repair is covered under warranty.
