Ik heb het maar aan chatGPT gevraagd (dus lezen met gezonde argwaan):
What is the root cause of Kia and Hyundai ICCU issues?
ChatGPT zei:
The root cause of Kia and Hyundai ICCU (Integrated Charging Control Unit) issues stems from overheating and potential failure of the ICCU, which can lead to 12V battery discharge, reduced power, and even sudden loss of drive power in affected vehicles.
Key Causes of ICCU Failure:
Excessive Heat and Overcurrent:
The ICCU handles charging and power distribution between the high-voltage and 12V battery systems. Some units experience overheating due to excessive current flow, leading to premature degradation of components.
Weak or Undersized Components:
Some reports suggest that certain internal components, such as fuses, diodes, or relays, may be undersized or prone to failure under extended use, particularly in high-demand driving conditions (e.g., hot climates, high-speed driving, or frequent charging).
Software and Communication Issues:
In some cases, faulty software or communication errors between the Battery Management System (BMS) and the ICCU may cause unexpected power cuts or improper charging, triggering warning lights and limp mode.
Affected Vehicles:
The ICCU problem has been widely reported in Hyundai Ioniq 5, Kia EV6, and other E-GMP platform vehicles (such as the Ioniq 6 and Genesis GV60).
Current Fixes:
Software Updates: Hyundai and Kia have released firmware updates to better regulate power flow and reduce stress on the ICCU.
ICCU Replacement: Some vehicles require a full ICCU replacement, often covered under warranty.
Fuses and Wiring Upgrades: In some cases, stronger fuses or revised wiring are being installed to improve durability.
Does the latest recall fix the iccu issue?
Yes, the latest recall aims to address the Integrated Charging Control Unit (ICCU) issues in certain Hyundai, Kia, and Genesis electric vehicles. This recall involves inspecting and, if necessary, replacing the ICCU and its fuse, as well as updating the ICCU software to prevent potential failures that could lead to a loss of drive power.
The affected models include:
Hyundai:
2022-2024 Ioniq 5
2023-2025 Ioniq 6
Kia:
2022-2024 EV6
Genesis:
2023-2025 GV60
2023-2025 Electrified GV70
