POWER TRAIN
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.

I leased the 2025 Hyundai Ioniq 6 in April of 2025, in November of 2025 the car charging time started to increase when using L3 charging stations. The normal charging time would be 15 minutes for the battery to reach 80% capacity and an additional 30 minutes for the battery to reach full capacity. After November it took 20 to 30 minutes for the battery to reach 80% capacity. On January 2, 2026, I was charging the car at a L3 station and when charging was completed the car no longer worked. The car displayed the message “Please unplug the charger to start the car.” But the car was not plugged in. I tried to trouble shoot for 20 minutes and had to call a tow truck for the car to be towed to Hyundai. The car sat at the Hyundai dealership for a week with the battery power draining from even though it was not turned on nor was it drivable due to the error message. According to the Hyundai website, there was an open recall on this car for the ICCU, and I show no record of this issue being fixed for this car prior to leasing it. The car is at the dealership still and has not been repaired.

ELECTRICAL SYSTEM
It is the ICCU (Integrated Charging Control Unit). The car lost power while I was going up a steep hill with a car behind me. The Hyundai dealership technician stated it is the ICCU (Integrated Charging Control Unit), and according to him, "We have ordered a replacement ICCU and FUSE. No eta on special order parts." The dashboard gave me the following message with a red battery symbol: “stop vehicle and check power supply.” In researching the VIN on the HYUNDAI SAFETY RECALLS AND SERVICE CAMPAIGNS website I learned that servicing was done on November 22, 2024 addressing this issue when it had just 19 miles on it. The Closed Campaign states: Recall 272, 2022-24MY IONIQ 5 (NE EV).2023-25MY IONIQ 6 (CE EV), 24MY IONIQ 5 ROBOTAXI (NERINTEGRATED CHARING CONTROL UNIT (ICCU) SOFTWARE UPDATE, ICCU & FUSE REPLACE. If my vehicle is repaired using a replacement ICCU that is of the same design, which has contributed to numerous failures, this does not instill confidence in their solution. I request that something be done to force Hyundai to FIX THE PROBLEM by identifying what is actually causing the ICCU to fail, and come up with a real solution, rather than a bandaid that needs replacing every so often.

POWER TRAIN
The ICCU assembly and high voltage fuse blew/broke at 6,255 miles as I was driving on Interstate 294. That immediately reduced the vehicle maximum speed to about 25mph, causing a hazard to myself and following drivers who were traveling at 55mph or more. I limped about 3 miles to the next exit, where Hyundai arranged for a tow and warranty service to replace the faulty parts. There were no prior symptoms or warnings. As this is both a known, ongoing (several years)Hyundai issue and apparently unrelated to driver behavior/practices, perhaps an NHTSA query will inspire Hyundai to actually resolve this issue instead of simply replacing the part(s)?

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 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.

ELECTRICAL SYSTEM
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 contact owns a 2023 Hyundai Ioniq 6. The contact received notification of NHTSA Campaign Number: 24V868000 (Electrical System), and the vehicle was taken to the dealer, where a software update was performed. The contact stated that the vehicle was charged at the residence, and the contact received notification through the Mobile App that the big battery charge was 80 percent. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The vehicle was towed to the dealer, where it was determined that the 12-Volt battery was completely drained and needed to be replaced. The contact stated that the recall remedy was intended to ensure that the big battery charged the 12-Volt battery during a charging session, but the recall remedy had failed to correct the issue as intended. The dealer informed the contact that the battery needed to be replaced prior to another attempt to perform the recall repair. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 55,000.

The ICCU on my 2023 Hyundai Ioniq 6 failed on December 5, 2025 after 19,616 miles. Luckily, the car was parked in my driveway when this occurred. If the car was in motion when the ICCU failure occurred it would have been very dangerous. The car cannot be driven. The car's system shows Hyundai Diagnostic Trouble Code (DTC) P1A906. The problem has been confirmed by a dealer. A new ICCU has been ordered. The car is under warranty and the dealer provided a loaner car while my car is being repaired.

ELECTRICAL SYSTEM, SERVICE BRAKES
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.

Subject: Safety Complaint – Sharp Upper Door Edge Causing Facial Injury (Hyundai IONIQ 6, 2023) Message: To whom it may concern, I would like to submit a safety complaint regarding my 2023 Hyundai IONIQ 6 (VIN: [XXX] ). On October 14, 2024, my wife suffered a facial injury caused by an extremely sharp upper edge of the front door. This occurred in our driveway at [XXX] . The injury happened when the front door stopped at its mid-detent position and the sharp, exposed upper edge made forceful contact with her forehead and the area next to her eye. She avoided a direct eye injury only due to quick reflex. This design presents a serious risk to passengers, especially those of shorter stature. I have photographic documentation showing the sharp door edge and the injury mechanism. Hyundai Motor America was informed, but they dismissed the case and advised us simply to “be more careful.” They offered a $150 virtual compensation card, which I did not use, because accepting it could be interpreted as accepting their proposed settlement. Hyundai insisted on dealer inspection, which is irrelevant because this is not a defect of a single unit — all vehicles of this model have the same door-edge geometry. I believe this is a safety-related design hazard affecting all Hyundai IONIQ 6 vehicles. I respectfully request that NHTSA review this case, as the risk of eye or facial injury is significant. Please let me know if you require additional information or photographs. Sincerely, [XXX] [XXX] Phone [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The ICCU had a failure and fuse also blew; vehicle needs those parts replaced. After reading about ICCU recalls, my vehicle was not in the last recall. It affected 2023-2025 models I started up my car in morning and was about to reverse out of my driveway. I heard a pop near the rear of my vehicle and then saw a "Check Electric Vehicle System" warning and battery light indicator on my dashboard. I tried driving around for a couple of minutes around my area, the car would not accelerate over 20-25 mph. I returned home and looked up the issue. My Hyundai app showed a Diagnostic Code of DTC P1A9096, which is related to the ICCU. I already have my car at a local Hyundai dealership to get it repaired under warranty but if it wasn't, I can only imagine the price it would cost to get this repaired. There should be more recalls.

I am reporting an odometer and title discrepancy involving a 2025 Hyundai Ioniq 6 (VIN: [XXX] ) purchased from Van Hyundai II LLC (Carrollton, TX) on January 6, 2025. The dealer issued two temporary tags with conflicting color entries and later reported the vehicle to the Texas DMV as having 57 miles at title assignment. However, the vehicle was involved in an accident on January 17, 2025, and the official Progressive Insurance repair estimate and Hyundai diagnostics (app data) both record approximately 535 miles at the time of loss. After the loss, the dealership and insurer (Progressive) processed a title transfer using the original Manufacturer’s Certificate of Origin (MCO), listing Progressive as buyer with $0 consideration and 57 miles. This resulted in a false odometer declaration on the title record and misrepresentation of ownership sequence. The matter is under review by the Texas Department of Motor Vehicles (Case #25-XXX) and other state agencies for related title and notary irregularities, but the mileage falsification falls under federal odometer regulations. I am submitting this to NHTSA to request review of potential violations under 49 U.S.C. §32705 (Disclosure of Mileage Upon Transfer) and 49 CFR §580.5–§580.8 (Odometer Disclosure Requirements). Supporting evidence, including the certified TxDMV title history, Progressive repair estimate, and Hyundai diagnostics..
