Hyundai, Kia, and Genesis are recalling almost 150,000 EVs within the U.S. over an electronics difficulty which will trigger 12-volt batteries to lose cost whereas driving.
The recall inhabitants consists of 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 GV80—in addition to 48,232 Kia EV6 electrical crossovers from mannequin years 2022 to 2024. That makes 147,110 affected automobiles in complete. This follows a recall of almost 170,000 Hyundai and Kia EVs in South Korea earlier this month for a similar difficulty.
All of those EVs have 12-volt batteries and electrical techniques along with their high-voltage battery packs. According to the National Highway Traffic Safety Administration (NHTSA), the fault right here lies with a part referred to as the Integrated Charging Control Unit (ICCU), which might be broken and cease charging the 12-volt battery, leading to a lack of drive energy.

This harm can happen by way of “various conditions such as overcurrent, over-voltage induced at the end of high-voltage battery charging, and certain thermal loading during operation or driving,” in line with recall paperwork. If a fault is detected, the automobile will difficulty warnings—together with chimes and dashboard lights—to the driving force and enter a “fail-safe” mode by which drive energy is step by step decreased.
Owners of affected automobiles can be contacted by the respective manufacturers relating to when to take their automobiles to dealerships, the place the ICCU and its fuse can be inspected and, if mandatory, changed freed from cost. Dealers may also set up up to date software program for the ICCU aimed toward reducing 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 techniques in new automobiles. One of the few fashions which have made the swap is the Tesla Cybertruck, which fits with 48-volt {hardware}. That’s after years of proposals, together with suppliers similar to Bosch proposing a vehicle-wide improve to 48 volts as a part of mild-hybrid upgrades.
Considering how the E-GMP platform utilized by the Hyundai Ioniq 5 and Ioniq 6, Genesis GV60, and Kia EV6 consists of 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.
