SC258 March 7, 2023 ATTENTION: ALL DEALER PRINCIPALS THIS IS A FOLLOW UP NOTICE TO ADVISE THAT THE REMEDY IS NOW AVAILABLE. Kia America, Inc., pursuant to the National Traffic and Motor Vehicle Safety Act, is conducting a Safety Recall Campaign on certain 2020 MY Niro EV vehicles manufactured from June 18, 2020 to September 4, 2020. The Electric Power Control Unit (EPCU) assembly in the subject vehicles may have been produced by the supplier with improper sealing. Due to this improper sealing, coolant can internally leak in the EPCU and contact the EPCU circuit board. If coolant contacts the EPCU circuit board, the vehicle may stall while driving. A vehicle stall increases the risk of crash. Dealers will inspect the Electric Power Control Unit (EPCU) for internal coolant leakage. If coolant leakage is identified, the EPCU will be replaced with an improved one.
