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).

Hyundai and Kia are recalling over 208,000 electric vehicles to fix a pesky problem that can cause loss of drive power, increasing the risk of a crash.
