Questions buyers ask

How many TSBs does the Hyundai Kona have?

NHTSA's manufacturer-communications file lists 493 technical service bulletins and related communications for the Hyundai Kona across the 2018–2026 model years. The most bulletined areas are electrical, engine, transmission & drivetrain.

Are Hyundai Kona TSB repairs free?

Not automatically. A TSB tells dealers how to fix a known pattern; you pay unless the vehicle is under warranty or the bulletin is a warranty extension or service campaign that covers your VIN. Recall repairs, by contrast, are always free.

How do I get the full text of a Hyundai Kona TSB?
