Some Hyundai models may have faulty wiring that would allow the vehicle to roll away. Other Hyundai, Kia and Genesis cars may have damaged EV charging units.

Omission of 48-volt electronics is particularly surprising in Hyundai's E-GMP vehicles, which incorporate various other advancements like 800-volt charging. Hyundai has even introduced a solution that does away with the old-style lead-acid 12-volt battery in some of its hybrids —but not any of its EVs thus far.

This isn't the first time E-GMP vehicles have been recalled over their Integrated Charging Control Unit (ICCU).
