Hyundai and Kia will be contacting the owners of certain 2021-2023 vehicles because of an internal fault affecting the electric oil pump in their transmissions. These automobiles are equipped with 2.5L turbocharged gasoline direct injection (T-GDI) engines and 8-speed dual-clutch transmissions (DCT)

Hyundai first became aware of the problem in September 2022 when the NHTSA’s ODI contacted them about a 2022 Hyundai Santa Cruz allegedly experiencing a loss of motive power while driving at various speeds. An investigation into the problem identified an internal fault with the DCT’s high-pressure electric oil pump as the likely cause of the vehicle entering “fail-safe” driving. Based on the information received, Hyundai decided to conduct a recall for affected vehicles. Because the same components are used on certain Kia vehicles, Kia also decided to conduct a recall.

The vehicles affected include:

According to the defect report, “The electric oil pump within the 8-speed dual-clutch transmission (DCT) may experience an internal fault due to insufficient soldering of a component of the electric oil pump circuit board. As a result, the subject vehicles may set a diagnostic trouble code with warnings and allow the vehicle to be driven normally for 20-30 seconds, followed by complete loss of motive power due to disengagement of the transmission drive gears.” If this happens, drivers will hear an audible warning chime, the message “stop safely immediately” on the instrument cluster and an illuminated malfunction indicator light (MIL).

Hyundai has received 229 unique incidents in the US related to this problem. Kia has identified 36 alleged incidents of loss of motive power due to an internal fault with the electric oil pump. Hyundai’s number for this recall is 236 and the NHTSA campaign number is 22V-746. Kia’s number for this recall is SC250 and the NHTSA campaign number is 22V-760.
