Issue
Integrated Charging Control Unit (ICCU) failures causing vehicles to lose power or shut down while driving. Affects E-GMP platform vehicles from Hyundai, Kia, and Genesis. Hyundai issued recall 24V204 in March 2024, then expanded to 24V868 in November 2024 when the first remedy proved insufficient. In April 2026 Hyundai extended ICCU warranty coverage to 15 years / 180,000 miles, and a federal class-action lawsuit was filed alleging that replacement ICCUs installed under the recall are themselves defective.

Summary

The Integrated Charging Control Unit (ICCU) combines the on-board charger and the DC-DC converter that keeps the 12-volt battery charged. When it fails, an E-GMP vehicle — Hyundai IONIQ 5 and IONIQ 6, Kia EV6, Genesis GV60 and the GV70 and G80 Electrified — can lose drive power or shut down while driving. Hyundai issued recall 24V204 in March 2024 and expanded it as 24V868 in November 2024 after the first remedy proved insufficient. What the ICCU is and why it fails is explained on our ICCU knowledge-base page; this page tracks the recall itself.

Timeline

  • March 2024 — Hyundai issues recall 24V204 for ICCU failures that can cause loss of drive power.
  • November 2024 — The recall is expanded as 24V868 after the first remedy proves insufficient.
  • April 2026 — Hyundai extends ICCU warranty coverage to 15 years / 180,000 miles.
  • Ongoing — A federal class-action lawsuit alleges that replacement ICCUs installed under the recall are themselves defective.

Is the ICCU problem fixed in 2026 models?

Short answer: the 2026 model year is outside both Hyundai ICCU recall campaigns on this record (24V204 and 24V868), and our 2026 Hyundai IONIQ 5 assessment describes the earlier failure pattern as “substantively resolved through a combination of software refinements and hardware updates to the charging control unit itself.” That is our editorial reading of the record, not a regulator finding.

What is on the record: recalls 24V204 and 24V868 cover the 2022–2024 IONIQ 5, the 2023–2025 IONIQ 6 and the 2023–2025 Genesis GV60, GV70 Electrified and G80 Electrified. Hyundai extended ICCU warranty coverage to 15 years / 180,000 miles in April 2026, and a federal class-action lawsuit alleges that some replacement ICCUs fitted under the recall are themselves defective. A newer model year is therefore not, on its own, proof that the failure is gone: if you see the symptoms below on any model year, have the vehicle inspected and report it to the regulator.

ICCU failure symptoms

An ICCU failure usually gives warning before the car stops. The symptoms we track, from our ICCU explainer: a “Check electric vehicle system” warning light; the 12-volt battery discharging without explanation; an audible pop or click followed by loss of power; and DC fast charging that will not start. If any of these appear, have the vehicle inspected before relying on it and file a report with the regulator using the links below — the report helps other owners even if your dealer is already handling the repair.

Model-specific steps: Hyundai IONIQ 5, Hyundai IONIQ 6, Kia EV6, Genesis GV60.

ICCU warranty extension

In April 2026 Hyundai extended ICCU warranty coverage to 15 years / 180,000 miles. The recall documents linked below do not define which vehicles and model years that extension covers, so confirm the terms for your specific VIN with a Hyundai dealer before relying on it. Kia EV6 owners: this page does not have Kia’s extension terms on record — ask Kia directly and keep the written answer.

Affected models and years

Hyundai IONIQ 5 (2022–2024), Hyundai IONIQ 6 (2023–2025), and Genesis GV60, GV70 Electrified and G80 Electrified (2023–2025).

Help other owners — file with the regulator

If your vehicle is affected by this defect, filing a complaint with NHTSA, Transport Canada, DVSA, or your regional regulator helps build the data record. Each report contributes to pattern detection that can trigger formal investigations and recalls — protecting other owners of the same vehicle, not just you.

You can file at any time, even if your dealer or manufacturer is already handling repairs. The regulatory complaint is a separate channel that helps every owner of your vehicle.
