I had washed my vehicle in my driveway. As I was drying it off, I heard a loud pop sound. When I went to put the car back in the garage, there was a warning displayed on the dash advising to check the vehicle electrical system. I immediately opened the MyHyundai app and it had a warning of an issue with the elecrtrical system and advised to schedule service. I had had no issues with the vehicle or its operation prior to this suddenly happening today. I fear that this is an ICCU issue as I have seen numerous complaints on forums and Reddit of over 90K 2025 Ioniq 5 vehicles this year alone having this issue. That’s an awful lot of vehicles to have the same issue.
Integrated Control Charging Unit (ICCU) malfunctioned. Turned car on and heard a popping noise, then car displayed check electrical system. Code P1A9096.

On [XXX] while driving the car on a city street in Northhampton, MA, I heard a loud "pop" and there were multiple warning lights, beeps and messages indicating there was a problem with the electrical system. The car slowed dramatically and I was unable to drive at a safe speed to keep up with traffic. The car slowly lost power and I was able to pull over to the side of the road. The temperature was 15 degrees F - very cold, no heat and I had to stay with the car in freezing cold temperatures to await transport via tow to the local dealer. The tow service required that someone be with the vehicle in order to receive a tow. The dealer diagnosed the car with a failed ICCU - a well-known, increasingly common issue with these cars - and said there were already 10 Ioniqs on the lot awaiting replacement ICCUs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I was on the highway going at approximately 60mph when the car without any warning reduced speed to first around 40mph and then to 20mph all within a matter of a few minutes, causing me to pull over to the side of the highway. Luckily, I wasn't injured. I exited the highway, called my insurance company Geico and had the vehicle …

I was on the highway going at approximately 60mph when the car without any warning reduced speed to first around 40mph and then to 20mph all within a matter of a few minutes, causing me to pull over to the side of the highway. Luckily, I wasn't injured. I exited the highway, called my insurance company Geico and had the vehicle towed to the dealership where I leased this brand new vehicle from just about 7 months ago on a 2year lease. The dealer was kind enough to provide a smaller loaner vehicle but had no idea when my car would be returned, as there were others with similar failures ahead of me that were waiting for the part to arrive. Apparently, this is a known failure issue of the ICCU that Hyundai has done a poor job of addressing. I continue to make my lease payments while waiting for the part to arrive. In the meantime, I wanted to let the government know of my experience and how this could have had a disastrous effect on my family and other families with a similar build.
Drove 50 miles. Charged car at a supercharger. Unplugged car normally. Pushed start normally. Heard a light “pop” sound. Car would drive but with low acceleration. Warning lights came on. Then bright “stop now” lights and beeping. Then it died in the parking lot and would not start at all.
The ICCU failed under normal utilization The vehicle went into limp mode which changes expected driving dynamics The dealer confirmed ICCU failure and the manufacturer has confirmed the vehicle is a lemon as per MA state law No warnings prior to the failure
Turned on my car one day after charging and heard a 'pop' from the rear of the car, followed by warning lights activating on the dash and an electrical system error message. I had the car towed to the dealership (Santa Monica Hyundai) and they confirmed the issue was an ICCU component failure. There were no warning signs or issu…

Turned on my car one day after charging and heard a 'pop' from the rear of the car, followed by warning lights activating on the dash and an electrical system error message. I had the car towed to the dealership (Santa Monica Hyundai) and they confirmed the issue was an ICCU component failure. There were no warning signs or issues before the failure. The dealership currently has no ETA for a fix.

My Ioniq5 has experienced a recurring water leak that has repeatedly exposed the left rear seat belt and seat belt retractor to large amounts of water. I noticed recently that after it had rained the left back seat belt was soaked and dripping water when pulled out. After fully pulling out the belt as far as it would go it was clear that the water had fully soaked the belt and retractor. It is unclear when this started or how long this has been occurring, as there was no warning or other indication that there was a leak until the belt happened to be put on soon after it had rained. I am uncertain if this poses an actual risk to the function of the seat belt or seat belt retractor. However, even though it is unknown if the water intrusion limits the seat belt's function, there is a perceived risk that this could corrode or degrade the function of the internal components due to the repeated water exposure. The car was taken to the dealership twice. The first time they claimed they were unable to repeat the issue. However, days later it rained again and the belt and retractor were again soaked. After the second return to the dealership they were able to confirm a leak in the glass roof of the vehicle that was allowing the intrusion to the seat belt and retractor. The car is still currently at the dealer awaiting repair for the water leak with an unknown timeline
