What's wrong?
The Electric Power Control Unit, or EPCU, in the 2021 Hyundai Kona Electric helps manage electrical power for the propulsion system. Inside it, the DC-DC converter changes high-voltage battery power into lower-voltage power the vehicle uses for other electrical systems. The unit also works near the coolant system, so its housing has to keep coolant out of the electronics.
On affected Kona Electric vehicles, the DC-DC converter housing was not sealed correctly during manufacturing. Hyundai traced the problem to inadequate steam cleaning before sealing, which left a path for coolant to leak inside the EPCU. The repaired EPCU uses a DC-DC converter with corrected sealing to stop that leak path.
An owner can see the malfunction indicator lamp come on. The information display can also show a "Check Electric Vehicle System" warning message.

Not every 2021 Hyundai Kona Electric is on the list. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
Coolant on the EPCU circuit board can cut drive power and increase the risk of a crash. If the malfunction indicator lamp turns on or the display shows "Check Electric Vehicle System," drive cautiously and contact a Hyundai dealer for guidance. Repair will be free at any franchised Hyundai dealer once Hyundai opens it.

What happens at the repair
Hyundai has not opened the final dealer repair yet. Once it opens, a Hyundai technician will inspect the Electric Power Control Unit, or EPCU, and replace it if the inspection shows the unit is affected. The final dealer repair will be free once available, with parts and labor covered under the recall. Hyundai's reimbursement plan covers out-of-pocket expenses paid to obtain a remedy for this recall condition. Ask Hyundai customer service or the dealer service desk how to submit documentation for reimbursement.
