2025 HYUNDAI IONIQ 6 Complaints

On the evening of February 11, 2026, my 2025 Hyundai Ioniq 6 SEL experienced a complete ICCU failure while I was traveling with my minor son. The vehicle became fully inoperable and left us stranded on the side of the road at night, in the middle of a winter storm. I was forced to call for a tow truck, wait in dangerous conditions, and arrange emergency transport for myself and my child. The vehicle was towed to Visions Hyundai of Henrietta, located in Rochester, New York. That was over three weeks ago. As of the date of my complaint, my vehicle remains at the dealership. I have been told that the replacement ICCU part is on indefinite backorder, with no estimated delivery date provided. I am left making full monthly payments on a vehicle I cannot drive.

ICCU failure. Sudden total electrical shutdown. According to this site, there was a recall filled but NOT COMPLETE since November 2024! We are now February 2026. There has been NO warning issued to Hyundai consumers about this. When the ICCU fails, it puts consumers at risk. When it happened to me, there was no shoulder to pull onto. Because there was a snowstorm that morning, the flatbed tow truck did not come for 3 hours. My car was in the shop for 3 days. The bottom line is that the failure of communication about this defect puts consumers at risk!

My leased 2025 Hyundai Ioniq 6 experienced a sudden malfunction resulting in loss of vehicle operation. The vehicle has been at the dealership with delayed diagnosis and no clear repair timeline provided. This appears to be a safety-related defect involving the electric system. I am aware of multiple reports and recent news coverage describing similar failures in Hyundai/Kia electric vehicles related to ICCU (Integrated Charging Control Unit) defects, which can cause sudden battery discharge and loss of propulsion. Media reports indicate that this defect has affected numerous vehicles and, in some cases, repairs have taken more than a month due to part availability and diagnosis delays. My vehicle experienced similar symptoms, including loss of power / inability to operate normally, and the dealer has not been able to promptly resolve the issue. This appears to be a broader safety-related defect rather than an isolated incident.

The car displayed “Check Electric Vehicle System”. The 12-V battery stopped charging. The vehicle could not be driven very far or very fast. The car had to be towed to a Hyundai dealer.The ICCU was diagnosed as failed. The ICCU has been an ongoing issue with Hyundai EVs.

I TOOK POSSESSION OF THIS VEHICLE ON SEPT 1, 2025 SINCE DAY 1 THE BLUELINK APP STATES THAT THE CAR NEEDS SERVICE I SPOKE TO HYUANDI CUSTOMER SERVICE & THEIR ONLY RECOMMENDATION IS THAT I GO BACK TO THE DEAL / I SAID TO THEM JUST YESTERDAY (FEB 12, 2026) SO LET ME GET THIS STRAIGHT / AM I SUPPOSED TO GO BACK TO THE DEALERSHIP EVERY DAY I THINK A RECALL IS NEEDED TO SEE WHAT IS GOING ON WITH THESE HYUNDAI CARS MY ORIGINAL CASE # IS XXX

THIS CAR WAS PREPPED BY COCONUT CREEK HYUNDAI AND I AM BEING TOLD BY YOUR CUSTOMER SERVICE DEPARTNEMTN THAT THERE MIGHT HAVE BEEN SOME DEBRIS ON THE WIPERS THAT CAUSED THE SCRATCHES / HOW IS THAT MY FAULT HYUANDI HAS WALKED AWAY FROM ANY RESPONSIBILITY / IN FACT THEY ASKED ME IF I CHANGED THE WIPER BLADES / I JUST GOT THE CAR 5 MONTHS AGO WORST CUSTOMER SERVICE

Battery is not charging to full capacity. The ICCU has been replaced and the battery is still not holding a full charge.

My car horn has ceased to work. I have not taken it in to be fix yet, but feel it is a safety issue.

this vehicle was delivered to me on Sept 1, 2025 / i have been back to the dealership a few times regarding the front windshield is totally scratched up this had to happen from the windshield wipers the issue is that when i drive into the sun the glare from all the scratches is annoying the second issue that hyundai cannot fix is that the app on the phone has stated since day 1 that the cars vehicle health needs attention / hyundai corporate response is that I should take it back to the deal EVERY DAY / i have no clue what is wrong with the car and if it is safe to drive hyundai corporate is washing their hands regarding both of these issues / they are doing the same thing now that they did to me in 2018 when they told me that I had to pay them to break a lease on a lemon law claim when they could not fix the 20+ issues that were wrong with my car i have case numbers if you want them

The ICCU died and the fuse on my traction battery blew. Both had to be replaced. I realized I had the problem when I started my car and it showed "Check Electric Vehicle System". When I tried driving it, I was limited to speeds below 45MPH, then eventually 25MPH, and eventually it would enter "turtle mode" and I could limp along at a couple MPH. I found the car would no longer charge the 12V accessory battery and it would no longer receive a charge from my home charger.
