Driving the car at 30 mph, the vehicle suddenly failed to accelerate while pressing on the gas pedal. I was forced to pull over as soon as possible to try to resolve the issue at hand. Thankfully, the breaks still worked and I was able to come to a full stop, turn off the car, and restart the car. There were no warning lamps/ messages that appeared before or after the time of the incident. (Incident occurred Aug 11) This is the second incident that my car's acceleration failed while in the middle of driving. Previously, this had happened while on the freeway during stop and go congestion (Oct 2025). This is a severe life-threatening safety concern as the failures have happened while the car is in motion during traffic. When I have taken the vehicle in for an inspection and diagnosis after the first incident, the Hyundai dealership was not able to reproduce the problem (Oct 2025) and therefore, could not provide any corrective services. I have not taken it in again for the second incident. The car is available for inspection upon request.

1. The HORN suddenly stops working. This happened 3x in a 6 month span. The first time the horn wouldn't work all day. However, next day it did. Second time it didn't work for 3 days. Last time it stopped working completely just before Memorial Day weekend. I have read it is a known issue in Hyundai Ioniq 6 forums. 2. Forward Collision Warning is to Invasive. Once it even stopped on the freeway while trying to merge in a difficult interchange. 2 cars almost hit me from behind when my car suddenly stopped. I was however in complete control of the situation. 3. Rear Backup camera stops to much when person is 8 feet past my car. It just suddenly STOPS even when person is walking away from the car. Snaps my neck too. Also, stops at night after rain. I believe it sees a reflection and thinks it is a hazard.

I experienced a safety critical failure in my 2024 Hyundai Ionic 6. While attempting to start the vehicle, the car displayed a red 12 Volt battery warning light, a battery discharge warning, and then refused to enter ready mode. The vehicle would only shift into neutral and was completely undrivable. After sitting for many hours, the vehicle started again, which is consistent with an intermittent ICCU/DC-DC converter dropout. This type of failure is known to cause loss of power and has been documented in NHTSA investigation PE23-011 for other Hyundai EV's. The dealership states they cannot replicate the issue and refuses further diagnostics. Hyundai corporate is deferring entirely to the dealership and will not authorize a loaner or confirm reimbursement, leaving me without transportation. They also stated they cannot commit to any repair unless the failure happens again despite the clear safety implications. This failure mode can cause sudden loss of motive power, which poses a serious risk if it occurs at highway speeds. I am reporting this because the vehicle is unsafe to operate, the failure was severe, and Hyundai is refusing to investigate the root cause unless it reoccurs. I am requesting NHTSA review this incident as part of the ongoing concerns regarding ICCU/DC-DC failures in Hyundai E-GMP vehicles.

What component or system failed or malfunctioned, and is it available for inspection upon request? The vehicle's cellular connectivity becomes 100% non-functioning until head unit reset. This occurs some days after the car is parked in an area without cell coverage and is then driving into cell coverage area, even directly under cell towers. It appears to give up trying to connect when parked out of range and never attempts to reconnect. until manually reset. How was your safety or the safety of others put at risk? Without in-vehicle connectivity, automated crash alerts / location information is unavailable. There's NO indication there's a problem unless certain information screens are visible, and only then, the indication is the lack of any connectivity signal level bars (a missing very small and dim icon) Has the problem been reproduced or confirmed by a dealer or independent service center? Yes via live phone assistance with Hyundai bluelink support. They suggested the manual reset and observed the re-establishment of connectivity. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not yet. I had the car in for a recall, but the service department said there was nothing they could do until Bluelink provided a fix. There's no fix announced. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, just the missing icon if you know where to look

Recall 272 - ICCU Ioniq 6 : ICCU fuse and update were required. Dealership ONLY did update. Did not replace fuse. Vehicle was "updated" for Recall 272 on 2/19/2025. Jenkins Hyundai Service Mgr, Savannah, confirmed on 5/18/2026 that this information is correct. In March 2026, the power seating failed to operate. This is directly related to Recall 272. However, when the vehicle was taken in for service, the dealership failed to diagnose and ONLY repaired pieces related to the seat. The vehicle was taken in on 3/18/2026 and stayed at the dealership for "repair" until 4/4/2026. This should have triggered the dealership to the Recall 272. On [XXX], within 1 hour of picking up the vehicle, all alarms went off indicating to stop driving the vehicle due to an electronic system error. DTCP1A9096. The vehicle was inoperable and had to be towed to the dealership. This should have triggered the dealership, again, to the Recall 272. On 4/22/2026, I was informed the vehicle was ready for pickup after replacement of the 12 volt battery. The issue was, again, directly related to the unrepaired recall 272. I was told that the 12 volt was not holding a charge. This should have triggered the dealership service, with the original issue, that it related back to the Recall 272. On [XXX] the power seats failed to operate. Again, related back to Recall 272. On May 9, 2026, the vehicle was taken to the dealership. On May 11, 2026 the dealership called to say that the fuse blew and was repaired. I ref

I was parking my car a Hyundai Ioniq 6, in an easy parking space when I briefly removed my foot, which was lightly depressed on the gas pedal to hit the brake pedal, the car suddenly accelerated jumped the curb hit another car and hit a tree. The airbag did not deploy I am uninjured. The other car was parked, but was damaged. My car was damaged. It all happened in about two or three seconds and my foot was no longer on the gas pedal. Moreover, the automated systems for parking collision warning, and for automatic stopping did not work. This is what came up when I googled it. Reports suggest some Hyundai Ioniq models, including potential Ioniq 6 instances, may exhibit unexpected, brief acceleration following a software update meant to address a separate braking recall. This issue is often linked to the "N-shift" mode, where the car may accelerate for 2-3 seconds after the driver lifts their foot. I had that software update

I was driving on the highway, 65mph when I had a sudden loss of power, check electrical system warning and a battery picture came on. I was reduced to approx 10mph suddenly in rush hour traffic, in the left lane, with no shoulder to pull over to. I was able, with the kindness of other drivers slowing down, able to move to the right lane, then to the shoulder. Called AAA for tow to dealership. 12v battery and ICCU damage.

Vehicle steering wheel was off-center and the vehicle wandered whenever the road changed camber or had rough sections. The vehicle was purchased used from Carvana,. I took it in for 4-wheel alignment and the tech reported that "All adjustment hardware at rear were pretty loose", and stated that it probably left the factory this way as he saw no evidence of prior adjustments. The left rear tire is badly worn on the outside and he recommended immediate replacement, which is awaiting warranty claim processing. Possible safety issues: Rear tire blowout, rear suspension alignment failure with loss of control.

ICCU failed. The car suddenly decelerated from 40mph to 25mph or less with no warning. The ICCU is confirmed to be an issue for Hyundai. I had the software update to fix the problem in 2025. It is currently at the dealership in Fort Mill, SC. DTC error code shows it as an ICCU failure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps to until the failure occurred.

After several days of below freezing temps, started car after work and received "check electrical systems" warning. Couldn't drive above 15-25 mph. Eventually led to total shutdown, could not start, lock/unlock doors, etc. Had to tow to dealer which they eventually deemed the ICCU to be at fault. 12v battery was dead and new battery they put in to test died it sounds like as well. Or they "recreated the problem" was their words after trying to claim it was only a bad 12v battery.

Driving 65 on the highway, the ICCU popped and died and the car immediately went into slow mode and decreased to 20mph in traffic in the snow. It displayed a message to pull over immediately and check the power system.

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.

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.

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.

ICCU failure. 5 minutes into my drive to work, the car slowed down, dashboard said electric failure and then died. It had to be towed to the dealership where it took a week to get ICCU replaced. Apparently a lot of Ioniq owners are having this problem. No warning signs, the car just dies. Car has 26,000 miles.

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.

ICCU SHORTED AND BLEW FUSE AFTER CHARGING. Shut off driving down the road.

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.
