NHTSA Complaint #11657178 — 2021 HYUNDAI KONA ELECTRIC

Fill coolant warning came on, we checked the coolant and the coolant level was good. I spoke to a Hyundai service center and the rep said that sometimes this happens with Hyundais and it may go off. Indeed it did but then Fill coolant warning came back and the coolant level was still good. After several weeks of the Fill Coolant warning being on more often than not, the car started one morning but couldn’t be driven as the handbrake was stuck on, the fill coolant warning was on and the tire pressure warning was on, (even though the tire pressure on all tires was ok) I guess this was the EVs way of saying “Do Not Drive Me”. We got the car to the dealership, they performed a scan and found no codes. They preformed a total coolant flush as per Service Campaign T9E. This service was performed on 21 April, 2025 and thus far the fill coolant light has stated off. We bought this car used just 2 months prior and found through previous maintenance history that this EV had this service Campaign T9E done in January 2024. Our concern with this issue is two fold, 1) My wife could have been anywhere when the car went into: Don’t drive me mode. 2) is this going to be an annual event, which will cost several hundred dollars to address each time when this may no longer be covered by warranty
