Report: Hyundai Extends Warranty on Problematic EV Charging Control Unit
What Car Shoppers Need to Know
- Reports of issue with onboard charger date to 2021
- Onboard charger failure can completely disable a vehicle.
- Hyundai and Kia reassuring owners with 15-year/180,000-mile warranty on affected component
Hyundai, Genesis and Kia already boast the best warranty coverage of any brands selling cars in the U.S. Powertrain coverage lasts for 10 years or 100,000 miles, while the bumper-to-bumper warranty covers the rest of the vehicle for the first five years or 60,000 miles. For owners of many of the brands’ EVs, that safety net just got a lot bigger: 15 years or 180,000 miles — but only for a specific part related to charging.

ICCU: I Can Cover U
The warranty applies to a part called the integrated charging control unit, or ICCU. Colloquially known as the onboard charger, the ICCU manages electricity flow in and out of the vehicle’s battery pack, and between that high-voltage pack and the auxiliary 12-volt battery. (Yes, even EVs have a standard 12-volt car battery.) While Hyundai Motor Group includes Kia and Genesis, so far, only Hyundai the brand has announced any action.
After customers worldwide began experiencing problems with their ICCUs in 2021, HMG finally issued a recall for almost 150,000 EVs in 2024. You can read about the issue in depth by clicking the link to the recall story, but the bottom line is that a failed ICCU can lead to a complete lack of power and an immobile EV.
Which Vehicles Are Affected?
The EVs affected are mostly based on HMG’s Electric Global Modular Platform, or E-GMP. The E-GMP architecture underpins small electric SUVs from Hyundai, Kia and Genesis. Other Genesis EVs may also be affected. The full list of vehicles and their associated model years with potentially faulty ICCUs is as follows:
Hyundai
- 2022-24 Ioniq 5
- 2023-24 Ioniq 6
Kia
- 2022-24 EV6
Genesis
- 2023-24 GV60
- 2023-24 Electrified GV70
- 2023-24 Electrified G80
Will Kia and Genesis Follow Suit?
Hyundai (the brand) announced the extended warranty in a statement to Torque News. It would make sense to expect similar statements from Kia and Genesis, but none have been issued yet. Kia responded to our inquiry by saying the brand “will update our dealers and EV6 owners on a similar program in the coming days,” and Genesis has not responded as of this writing. Stay tuned.
