My 2024 Hyundai Kona Electric lost power several times while driving on roads and highways at various speeds. The first instance was on [XXX] near Burlington, MA on [XXX], and then it happened several other times before we were able to get the vehicle to a Hyundai dealership for diagnosis and repair. The power loss typically manifested in the vehicle stuck at about 20-25 mph despite generous use of the accelerator pedal (often to the floor). There were no error messages or similar diagnostic information provided before, during, or after moments when power loss occurred. Often the vehicle would return to normal operation after a few minutes or by turning the vehicle off and back on again. The safety of the driver and passengers was at significant risk, especially on higher speed roadways due to the slow speed of the Kona in these moments. The dealer service department completed extensive diagnostics as detailed in the service report PDF attached. They ultimately found a nut (designated "ge09") connecting several ground wires to the chassis was loose. After replacing the nut and tightening to specification the problem has not recurred. We are satisfied with the communication and fix from the dealership and Hyundai corporate representatives, but concerned other Hyundai owners might encounter this issue with their vehicle.
