My husband was driviing to work on the freeway when suddenly the instrument panel lit up and the Kona Stalled right there on the freeway. No indication that anything was about to occur, and he was traveling with the flow of traffic at about 65-70mph. We purchased the car used from a Hyundai dealership and we purchased the CPO extended warranty as well. Why do the dealers say they have no idea what it is because they can't duplicate it? It's intermittent, it happens when it wants to, it's happened to us four times now. Obviously from what I see here, this is a KNOWN PROBLEM.
