ICCU Recall
for My Ioniq 5

March 28, 2024



Earlier this month I heard that Hyundai Motors had issued a recall to fix a potential problem in the Integrated Charging Control Unit (ICCU) in 2022-2024 Hyundai, Kia, and Genesis EVs that share the same drivetrain. Those who would like to know more about the history behind this particular repair are welcome to open this PDF by the National Highway Traffic Safety Association.

I am glad to see that Hyundai takes such a proactive approach to supporting its vehicles —and its customers. As readers will recall, Tesla refused to cover a similar problem with its charging controller under the High Voltage Battery Warranty —which really soured me on the automaker and ultimately led me to get rid of my Model 3 and replace it with my Ioniq 5 Limited.

To be fair, I should point out that, in reality, Hyundai’s ICCU problem is not as widespread as one might believe: out of ~146,000 EVs sold, only 618 instances have been reported. Since my 2024 Ioniq 5’s VIN is included in the list of vehicles affected, I immediately contacted my local dealer, Findlay Hyundai, to set up an appointment for the recall. They fit me into their schedule in less that a week, and here is a brief report of having the work done.

I arrived at the Service Center at the dealership a few minutes before my appointment at 9:15 in the morning. Because I had once contacted Hyundai to report that Bluelink wasn’t working, they wanted to also reinstall it as part of their service —even though I had already activated Bluelink.

Here is my Ioniq 5 ready to enter the service bay for the repair. I surmise that Hyundai insisted that they reactivate Bluelink again to make sure it was operating properly. I consented to let them do so. In fact, I have noticed that now the Bluelink app on my phone shows a photo of my car —which wasn't there before!

Until only recently, Findlay Hyundai was not selling or servicing the automaker's EVs, but just last month I noticed that they had finally decided to follow the example of other dealerships. I was pleased to see that they now had an Ioniq 5 identical to my own on display, right next to a new Kona.

Inside the showroom, I saw a Hyundai Venue, which struck me as a competitor to small hatchbacks like the Mini Cooper EV and the Fiat 600e.

I told the sales rep in the showroom that the Venue would be real winner if they simply managed to make it an EV runabout.

It took the service technicians about 3 hours to complete both the Bluelink activation and the ICCU recall. For those interested in the work performed, here is a copy of the service invoice for the work —which of course cost me zero, zip, zilch, nada.

Let’s hope that the new software installed for my ICCU will eliminate whatever problem previous owners had experienced with its power and charging. The only thing I noticed upon retrieving my vehicle was that many of the car’s functions had reverted to the factory settings, an understandable consequence of rebooting the system after installing new software. I have since re-entered my own preferred settings for Drive Mode, the Heads Up display, the layout of the infotainment screen, my bluetooth devices, my Driver Profile, etc. I was glad to get the vehicle back without delay, for we had already planned to take a day trip to Las Vegas the very next day.
