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.

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.

NHTSA announced a recall of 200,000 EV models from Kia, Hyundai, and Genesis due to a potential loss of drive power and faulty transmissions.
