Hyundai and Kia will extend warranties for cars with ICCU issues

Hyundai Motor Group has announced that it will extend warranties for cars that suffer from a rare issue which has nevertheless plagued some owners, potentially causing cars to lose power.

Some of Hyundai and Kia’s E-GMP vehicles have suffered from a persistent issue with the cars’ Integrated Charge Control Unit which can lead to loss of power, either stopping a car from starting or even stranding drivers mid-drive.

While the issue is rare (around ~1% of cars), affected owners have sometimes had to wait months for service or had multiple failures even after the part was replaced.

Hyundai has implemented some fixes, including a recall and software updates, attempting to reduce voltage spikes that could pop a fuse when charging the 12-volt battery, which seems to be the problem.
