2024 Hyundai Ioniq 6

The morning after a successful level 2 charge (from 35% to 80%), the ICCU fuse blew, resulting in no power to the car. I had to have it towed to have it fixed (both the fuse and ICCU were replaced under warranty). The car had 20,013 miles when the fuse blew and I had both safety recalls (software updates) addressed when they came out. I thought the updates were to prevent this from happening. Fortunately I was in my garage and not on the road; however, just the evening before, I was on I-95 for over an hour and glad it did not occur then. So now I'm fearful that it could happen again when far from home.

I had the ICCU unit recall taken care of on my car. While driving yesterday evening, I had a complete power failure. There were warning lights on the dashboard so I slowed down until it finally totally stopped. The warning lights said check electrical system and a yellow turtle light came on. While waiting for the tow truck all electric stopped including the flashers. It was dark, during rush hour and 10 degrees outside. I was left stranded, blocking traffic and with no heat. People were honking their horns and fighting to get around me. The street became one lane. It was very dangerous for me, I was a sitting duck. It also became dangerous for pedestrians trying to walk while cars squeezed around my car. Again, all of this happened in the dark in 10 degree weather. I waited all day to get a diagnosis from the dealer but they were too busy. I was not given a loaner car and have been stranded at home and lost a day of work. I had to have my car towed home last night and waited for a tow again to take it to the dealership. I may lose another day of work tomorrow.

When driving recently, the car suddenly began showing a warning message “check electrical system” and would not go beyond 25mph. I was on the way home but still far, and had to turn on my hazard lights to alert other drivers. Eventually the car escalated the warning to “pull the vehicle over” and implied that the main battery was having an issue. I had to have th car towed to a dealer (closest is 10 miles) who eventually diagnosed the issue as a blown ICCU. My understanding is this is a critical component to the charging infrastructure and must be fully operational for the car to safely drive. Hyundai repaired the part and I had the car back in a few days, but I could get no assurances on what happened or whether or not it would occur again. The car has 14,000 Miles in the Washington DC area. It seems incredibly unsafe that this component could blow at any time. I also understand there are many other owners with this exact issue.

Two years into my lease. I used my turn signal as normal, heard a loud CRACK as I pushed it down to signal a left turn, and the turn signal started to sag inside of its compartment behind the steering wheel. I did not use more pressure than normal, and I have never had this issue with another car before. The turn signal BROKE with normal use. This is not covered by warranty and I was quoted $1400 repair by the dealership.

The ICCU failed on my vehicle after 25,000 miles on a 2024 model year car. Driving on a cold and wet night, after pulling away from a stop sign, we heard a large POP and then dashboard lights indicating an electrical system problem. Apparently the sound was a fuse blowing, and then the car went into limp mode. We were able to drive at approximately 24 mph for about 5 minutes before the car told us to stop immediately. We had to get the car towed to a dealership the next day, after getting it towed to our house first. If this had happened on a freeway it would have been a very dangerous situation. We were told it was a just a "bad part". But there had been a previous recall for software update, and this part still blew up. There is nothing we are told that can be done and some of the units are just bad. Hyundai should find the ROOT CAUSE of this issue, and fix it!

The power system failure warning came on as I was driving up on an intersection. WhenI released the accelerator because I was in i-pedal mode (one pedal driving), the cars braking system did not activate. Consequently, I ran the red light. The car power was reduced, and I was able to pull into the parking lot of a strip mall as a police vehicle pulled behind me. After explaining our situation and receiving my traffic ticket, the officer asked me to move the car out of the driveway, but I was unable to shift the car into drive given the power warnings that were flashing on the display. The officer asked if I needed a tow and I let him know I would use the brand’s Roadside Assistance for my vehicle. I turned the car off and the officer left. I waited about 10 minutes and I tried turning on the car again and was able to shift into drive and get out of the driveway and into a parking space. However, the car operated in low power mode and could only travel about 3 miles an hour. The tow truck driver had to jump the 12 V battery which was completely depleted in order to turn on the vehicle to move it. At Hyundai Service center, the car turned off abruptly as he was trying to move it into a parking spot. Despite supposedly having been addressed in a recall, the failure of the vehicle’s power system due to the ICCU put me in my family at risk while actively driving on a road with traffic.
