What's wrong?
The electric oil pump assembly in the 2023-2024 Hyundai Kona, Elantra, Tucson, Sonata, and Palisade helps move transmission fluid where it needs to go, including during Idle Stop & Go operation. Its electronic controller tells the pump when to run, so the transmission has oil flow when the engine stop-start system is active. That controller depends on a printed circuit board with stable electrical components.
On included vehicles, capacitors on the pump controller's printed circuit board were damaged during production. A capacitor is a small electrical part that stores and releases charge. When damaged capacitors are inside the controller, the controller can overheat instead of operating the pump normally. Hyundai says the replacement electric oil pumps use properly manufactured printed circuit boards from a different controller supplier.
Warning signs include smoke from under the vehicle, a burning or melting odor, or a malfunction indicator light with other warning lamps on the dash. Treat those signs as a reason to stop driving and contact a Hyundai dealer.
