January 28, 2026 The vehicle has stopped in the middle Of the street with sign «loss of power, check your battery» or something like that and after few attempts to turn it off and on it went to Accessory mode. After 15-20 minutes it completely died. So unsafe with kids in the car during extreme cold temperatures. Free Hyundai road assistance- quoted me 3 hours or so, i had to pay for towing elsewhere. No doubts its iccu, since tow truck driver attempted to jump start and from dead it went to accessory mode and died again almost instantly. I read on the Facebook about iccu problem of Hyundai, if this is engineering defect it should be remedied.
Horn fuse has blown 4 times in 5000 miles leaving the vehicle unsafe to operate. Problem is reproduced and confirmed. First started in November 2025 and 4th fuse was placed January 2026.

By the time I pulled over to the side of the road my car was dead. Ive been trying to get Hyundai and the dealership to dignose the issue.…

The vehicle popped up a screen that said check power source. Then within 30 seconds went into limp mode said power was limited and couldn't drive faster the. 25mph in the middle of a highway. By the time I pulled over to the side of the road my car was dead. Ive been trying to get Hyundai and the dealership to dignose the issue. Based on the error codes I was given it appears to be a dead iccu and 12v battery. I am in a ioniq group on Facebook and over the last week of being in it I've counted over 50 dead iccu on this group alone. All in one week.
I was driving, there was a loud pop, then warnings popped up on the dash and I lost power. I was able to limp the car back to my house, because I had just left. I assume it is the ICCU. I’m reporting this because it is a known issue that Hyundai has not seemingly been able to repair. With the pedal to the floor, I got up to…

I was driving, there was a loud pop, then warnings popped up on the dash and I lost power. I was able to limp the car back to my house, because I had just left. I assume it is the ICCU. I’m reporting this because it is a known issue that Hyundai has not seemingly been able to repair. With the pedal to the floor, I got up to 25 mph. Luckily, I was near home and not on a highway.
The iccu failed. The car went into check power mode the. Into slow mode then died on the highway. Hard to ah e it jumped to take it to the dealership only to find out the 12v and iccu died

The contact owns a 2023 Hyundai Ioniq 6. The contact had received a notice of NHTSA Campaign Number: 24V868000 (Electrical System), and the vehicle was taken to the dealer, where the Integrated Charging Control Unit (ICCU) software update was completed. The contact stated that while driving 50 MPH on the highway, the vehicle stalled. The contact was able to pull over to the shoulder of the road. It was unknown whether a warning light had illuminated. The vehicle failed to restart and was towed to the dealer, where it was diagnosed that the Integrated Charging Control Unit (ICCU), and the 12-Volt battery had failed and needed to be replaced. The dealer ordered the parts. The contact stated that the recall remedy had failed to correct the safety issue. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that parts would be shipped to the dealer for repair. The failure mileage was approximately 14,000.
The horn from my car has stopped working entirely. By having this system fail it endangers me from other clueless drivers on the road.

1PE24028 · Electrical Arcing And Thermal Events, Potentially Leading To Fires, While Utilizing Enel X Way Usa, Llc's Juicebox Residential Charger.
Opened Oct 3, 2024 · Closed Jun 5, 2025
Status: closed (inferred from source dates) · Equipment:electrical
On October 3, 2024, the Office of Defects Investigations (ODI) opened PE24028 to investigate alleged failures of Enel X Way's JuiceBox Level 2 residential EV chargers. The allegations were described as thermal incidents and electrical malfunctions, which could trip the circuit breakers in Juicebox owners’ homes and disrupt electric vehicle charge cycles. On October 2, 2024, Enel X Way posted on its website that Enel X Way North America would cease operations in the United States and Canada on October 11, 2024. The closure would potentially impact the charging app and supporting software. ODI sent Enel X Way an Information Request (IR) letter on October 21, 2024. Enel X Way provided an incomplete response to the IR on December 9, 2024. Enel X Way later provided a complete response to the IR on January 24, 2025. ODI reviewed Enel X Way’s IR submissions to determine whether further action is required. Based on ODI’s analysis, there was no clear trend in the cause of the failures described in customer complaints and warranty reports. Additionally, there have been no recent reports alleging safety issues. The available information does not warrant further action at this time. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency will continue to monitor for any safety trends and reserves the right to take additional action if warranted by future circumstances. To review the ODI reports cited in this Closing Resume, go to NHTSA.gov.
