Hyundai, Kia, and Genesis are recalling practically 150,000 EVs within the U.S. over an electronics situation that will trigger 12-volt batteries to lose cost whereas driving.
The recall inhabitants contains 98,878 Hyundai and Genesis EVs from mannequin years 2023 and 2024—together with the Hyundai Ioniq 5, Hyundai Ioniq 6, Genesis GV60, Genesis Electrified GV70, and Genesis Electrified G80—in addition to 48,232 Kia EV6 electrical crossovers from mannequin years 2022 to 2024. That makes 147,110 affected automobiles in whole. This follows a recall of practically 170,000 Hyundai and Kia EVs in South Korea earlier this month for a similar situation.
All of those EVs have 12-volt batteries and electrical methods along with their high-voltage battery packs. In accordance with the Nationwide Freeway Site visitors Security Administration (NHTSA), the fault right here lies with a part referred to as the Built-in Charging Management Unit (ICCU), which may be broken and cease charging the 12-volt battery, leading to a lack of drive energy.

This harm can happen by way of “numerous situations equivalent to overcurrent, over-voltage induced on the finish of high-voltage battery charging, and sure thermal loading throughout operation or driving,” in accordance with recall paperwork. If a fault is detected, the car will situation warnings—together with chimes and dashboard lights—to the motive force and enter a “fail-safe” mode through which drive energy is steadily lowered.
Homeowners of affected automobiles might be contacted by the respective manufacturers relating to when to take their automobiles to dealerships, the place the ICCU and its fuse might be inspected and, if crucial, changed freed from cost. Sellers may even set up up to date software program for the ICCU aimed toward lowering thermal loading and peak voltage. The software program additionally alters the operation of the water pump to additional decrease thermal loading.

Automakers have been very sluggish to do away with 12-volt electrical methods in new automobiles. One of many few fashions which have made the swap is the Tesla Cybertruck, which fits with 48-volt {hardware}. That is after years of proposals, together with suppliers equivalent to Bosch proposing a vehicle-wide improve to 48 volts as a part of mild-hybrid upgrades.
Contemplating how the E-GMP platform utilized by the Hyundai Ioniq 5 and Ioniq 6, Genesis GV60, and Kia EV6 contains numerous developments like 800-volt charging, 48-volt electronics are a shocking omission. Curiously, Hyundai launched a brand new answer that does away with the old-style lead-acid 12-volt battery in a few of its hybrids—however none of its EVs function the answer.
