ELECTRICAL SYSTEM
Warning came on the dashboard to check electrical and stop driving which I did and started up the car again and was only able to drive another minute until the entire car lost power while trying to accelerate and I had to have an emergency pull off into a strip mall off of a busy street car was towed although the Hyundai Road assistance did not know that the dealer they towed to was not able to work on electric vehicles, and therefore had to be restored. At this time, I was told it was an ICCU issue. The part was ordered, and I am waiting to hear back from the dealership.

ELECTRICAL SYSTEM, POWER TRAIN
-ICCU failure, identified by dealer service department as the cause of catastrophic failure. -The car suffered a catastrophic failure on a 2-lane country road in Princeton NJ on [XXX] at approximately [XXX] at night in 20 degree temperatures. Every function except blinkers (temporarily functional) ceased to work. I waited in the car, without heat, for an hour before service arrived. The car could not be moved and was left in the road until 3:00 am, when the towing company I paid towed the car to my driveway a mile from the failure site. -My safety was at severe risk while I waited in the car. -Dealer replaced ICCU assembly with the same part, with the possibility of repeated failure. -Warning messages appeared somewhat over a mile before catastrophic failure. The car slowed to 11 mph. -Hyundai has known of the potential for catastrophic ICCU failure in their electric cars since 2022. I took possession of this 2025 model in March 2025. I was never informed of any recall, although it appears that a recall was issued at the end of 2024. -Hyundai has denied compensation for irresponsibly, with knowledge of the potential failure, subjecting me to a hazardous, life-threatening situation. -Anecdotally, of the 4 Ioniq owners I know, 3 have experienced ICCU failure.

ELECTRICAL SYSTEM
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)?

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..

WHEELS
My car was parked and I noticed that there was a bump in the sidewall of my vehicles driver front tire. This is the 2nd time this has happened in a month with factory installed tires that came with the vehicle when purchased brand new. I have had my 2025 Hyundai Ioniq 6 SEL since 12/13/2024. I already submitted an NHSTA safety ticket on 2/3/2025 due to my driver rear tire exploding while driving. Ticket # 11640496. This is extremely dangerous and can kill myself or someone else on the road, especially on highways. There is a defect in these tires that Hyundai had partnered with Pirelli to install on brand new Ioniq 6 SEL vehicles. I am lucky I caught the bump on the side of the tire before it exploded while driving. I have attached the pictures of the tire from this 2nd incident.

TIRES:TREAD/BELT
Pirelli 245/40 R20 99W The driver rear tire had blown out on me as I was merging onto a highway. I heard a heard a loud pop sound and the car shook and I had to swerve back into my lane. I looked around me and there were no objects or pot holes. My tire emptied down to 7 PSI in about 5-10 seconds. I immediately pulled over to the side of the road. I inspected my tire and there was no damage to the exterior of the tire (nails, screws, debris, etc.), as well there was no scraping of the tire or abrasion. When the repair tech took off the tire to replace it he noticed the steel belt had separated on the tire and had protruded from the inside out and caused the tire to blow. This was extremely scary and dangerous. If there would have been a car to my right my car would have crashed into another car. My car is brand new and I've had it for about 1 1/2 months. It is a 2025 Hyundai Ioniq 6 SEL that was manufactured in 2024. The car has it's original tires from the manufacturer Hyundai. The tire is defective and was not safe to drive. I contacted Hyundai corporate and the dealership about this and they did nothing to reimburse me for the defective tire. I not only am still working for compensation for the tire that was $400 after taxes and fees, but I am trying to alert Hyundai about safety of this model tire.

We were not informed of the recall in a timely manner. Discovered it online and called dealer to make appointment. They would not give us an appointment for about 3-1/2 weeks and we were told we have to leave the car for 4 to 5 hours. Notification we eventually got later stated repair would take 30 minutes. The dealer provides no transportation to or from, so it means waiting there for 5 hours or paying a service to drive us home and back. This is inexcusable. The car is brand new and repair is supposed to be free. It would cost us $100 in transportation to and from if we do not wait for it. If this is a safety issue, we should not have had to wait so long for an appointment. That is NOT timely.
