What's wrong?
The electronic power control unit, or EPCU, in the 2017 Hyundai Ioniq Electric manages high-voltage power for the electric drive system. It helps route and control electricity so the battery, motor, and related control electronics work together when the vehicle is moving. The circuit board inside that unit has to stay dry and protected.
On affected Ioniq Electric vehicles, the EPCU housing was cast with small voids from the manufacturing process. Those tiny openings let coolant reach the unit's circuit board. Coolant on that board can interrupt the electronics that keep propulsion working, which is why reported vehicles showed a "Check electric vehicle system" light and the motor turned off.
There is no warning sign before failure. If the condition appears, the driver can see the "Check electric vehicle system" light and lose motor power.

What happens at the repair
At the dealer, a Hyundai technician inspects the Electronic Power Control Unit for the coolant-related defect and replaces the EPCU if needed. The recall repair is free, with parts and labor covered. Hyundai says this EPCU repair is covered for 15 years or 150,000 miles under the new vehicle limited warranty, so prior out-of-pocket repair costs are handled through warranty coverage instead of a separate reimbursement program. Ask the service desk how that warranty coverage applies if you have prior repair paperwork.
