Hyundai’s Recall Nightmare: Defective Cars Resurface, Owners Fuming

As soon as the ICCU recall was issued, the same defect reoccurred
Leading to the vehicle being towed

The controversy over the ICCU (Integrated Charging Control Unit) defect issue shows no signs of abating. Hyundai and Kia previously initiated a recall for approximately 170,000 electric vehicles. Almost all electric models are targeted, including the Ioniq 5, Ioniq 6, EV6, and Ray EV.

However, there have been cases where the same problem reoccurred on the same day the ICCU was replaced and updated, causing controversy. ICCU-related issues have been persistently raised in the past. Despite several updates to improve the software, the problem remained unresolved, leading to a flood of complaints from consumers.

On the way to work, the vehicle was picked up, and a power reduction occurred

The vehicle in question is known to be a Genesis GV70 electric car model. The “Check Power Supply Device” warning light was activated, which turns up when the ICCU has an issue and a power reduction occurs. The driver was ultimately forced to have the car towed as regular operation became impossible.

The ICCU manages high and low-voltage currents and charges the low-voltage battery. If the ICCU does not work, the low-voltage battery does not charge and discharges. Typical symptoms include a “thud” sound and the activation of a “Check Power Supply Device” warning on the dashboard. A decrease follows this in output.

Is Hyundai failing to solve the problem?
Criticism is pouring in

However, this situation had no “thud” sound, raising the possibility of an additional separate issue. As problems persist even after the recall measures, some point out that Hyundai may not be able to solve the problem. There have also been cases where those included in the ICCU recall visited the service center only to be told that the update had already been applied and no action was taken.

However, this year’s software update has a different codename from last year, suggesting a separate update. Due to this confusion, some service centers may have mistakenly provided incorrect guidance. With the unprecedented recall of 170,000 vehicles underway, there will likely be substantial confusion among vehicle owners and chaos on site.

Service center reservations are backed up, making getting a recall difficult

One vehicle owner was reportedly turned away after being told to make a reservation when he visited the service center at opening time. Depending on the service center, reservations can be backed up for more than two months, causing vehicle owners to scramble to make appointments. There have been instances of customers having to wait for several hours despite making appointments.
