ELECTRICAL SYSTEM
While charging at home with provided Level 1 Charger, the vehicle will suddenly stop charging. When it stops, it appears to be surging an electrical charge back into the home (black marks on outlets requiring an electrician to replace, black marks on the charger plug, and most recently, threw a breaker on our home electrical panel). This is a fire hazard.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
I was coasting into a library parking space with my foot off the accelerator. The car accelerated even with my foot on the brake, jumped a curb and was stopped with above ground tree roots. The dashboard should have been lighted up with collision warning indicators and the automatic braking should have engaged. It did none of that. The car was totaled. Nothing was ever checked to see if it was a mechanical error. My insurer totaled the car.

I am submitting an update to my existing complaint regarding the ICCU safety recall on my 2022 Hyundai Ioniq 5. Since my original submission, my vehicle has been at authorized Hyundai dealerships since July 2025 and remained undiagnosed and unrepaired for over three months. During this time, I received inconsistent and misleading information from both Hyundai corporate and the dealerships regarding the status of the recall repair, as documented via emails, texts, and recorded calls. On 10/31/2025, the dealership informed me that the issue may involve a floor harness/wiring problem and it is out of warranty; however, this appears related to the ICCU safety recall, and Hyundai has not provided a firm timeline for repair. Hyundai’s delay has caused significant inconvenience, as I have been without my vehicle while continuing to make car payments and insurance payments, and arranging temporary transportation. Additionally, Hyundai and the dealerships provided multiple assurances that the vehicle was being diagnosed and repaired, which were later contradicted, reflecting misleading and deceptive practices. I request that NHTSA consider this update as part of my ongoing complaint and investigate Hyundai’s failure to provide timely and adequate recall service, as well as the misinformation surrounding this safety recall.

ELECTRICAL SYSTEM
My ioniq 5 has had the ICCU and 12V battery replaced in April, due to ICCU failure. Since then on two separate occasions the car has drained the 12V battery while parked. Both times were shortly after driving the car, so the 12V battery should have been fully charged. I believe multiple recall campaigns have been made related to this issue, but my car still appears to exhibit the symptoms after receiving the updates. * I believe the ICCU software is faulty and is not correctly charging the 12V battery. * This fault makes the car likely to strand my family unexpectedly (a safety issue), as it affects even the newly replaced 12V battery. * I have not taken this vehicle back to the dealership since the ICCU was replaced, since the 12V battery has only drained twice since then, I feel like it is unlikely they will be able to reproduce the issue. * No warning lamps or fault codes stored in the ECU.

Despite being up-to-date on recalls for this vehicle intended to address failures with the integrated charging control unit (ICCU), I still experienced an ICCU failure. I was driving along a surface road at approximately 40 mph for about 9 minutes when I heard a pop that sounded like cargo shifting in the rear cargo area. The vehicle then flashed a "Check EV System" warning but otherwise continued to operate normally. About 2 minutes later, there was a warning to stop vehicle and check power supply. After I pulled into a parking lot, I restarted the vehicle, but the errors persisted. I had the vehicle towed to the dealer, where it was diagnosed as an ICCU failure. The vehicle was last charged ~15 hours before the failure on a level 2 charger at a peak rate of 6 kw. The vehicle was driven for about an hour after charging, sat overnight, before being driven when the failure occurred. The vehicle is primarily charged using level 1 and 2 charging, typically not exceeding 6.3 kw. Only a handful of times has level 2 charging rates exceeded 6.3 kw. The vehicle previously had the ICCU fail and replaced in 2023. The car is still at the dealership with no repair timeline.

FUEL/PROPULSION SYSTEM
Battery conditioning (heating) is required for fast charging at cold temperatures. The current method of enabling this function takes many steps including going into the EV setting to enable this option (since it automatically turns off when changing some settings in the Hyundai Bluelink App), then opening the navigation screen, looking at a map and scrolling though a long list of charging sites, picking the desired charger then starting the navigation and route to that site. This has to be to done while in route to a specific charger, normally this would be on the freeway 20-40 minutes before arrival at a fast charging station. It is a distraction while driving and is an issue with all Ioniq 5's sold from 2022-2024. Hyundai fixed this problem for the 2025 model year but have not do so on the previous cars at this time. Hyundai needs to add this 1 touch preconditioning option for safety and driver ease of use. I feel it should required on all EVs that offer battery conditioning. I have told them about this several times and not gotten a response and according to posts in various online communities many other have also reported this issue to Hyundai but they have taken no action.

For the check electrical warning. Took to dealer and they diagnosed it as a failed ICCU. In another issue, smelling sharpie from the air vent. Which might indicate a HVAC issue.

ELECTRICAL SYSTEM, POWER TRAIN
The Integrated Charging Control Unit (ICCU) in my 2022 Hyundai Ioniq has not been diagnosed or repaired despite being at the dealership for 3 months for a safety recall. The ICCU controls the vehicle’s electrical and charging systems, and a malfunction could prevent the vehicle from charging or operating properly, creating a risk of loss of propulsion while driving. Two different Hyundai dealers have had the vehicle since July 11, 2025, but no diagnosis or repair has been completed. I have escalated the issue to Hyundai Corporate, but there has been no resolution or communication of a timeline. The vehicle is available for inspection upon request. No warning lamps or messages were reported prior to the dealer receiving the vehicle, as the car was delivered specifically for the recall repair. Due to this unresolved recall, I have been without my vehicle for 3 months, which has caused significant hardship and forced me to rent a vehicle temporarily. I was given a loaner vehicle eventually but this vehicle is not comparable to my ioniq5. Both dealer's gave excuses for the lack of diagnosing and repairs, ranging from "technician is on jurty duty" or "the climate is too hot outside to look at it."

WHEELS
A severe vibration started suddenly in the steering wheel and persisted between ~55 and 65mph. The first occurrence almost caused a crash on the highway and significant driver input force was needed to control the car. The dealer found that quieting foam glued inside the tire had come loose and caused an unbalance. They started they had seen this several times now on these cars.

The contact owns a Nuna Car Seat, Model Name: Rava, Model Number: (N/A), Model Type: (N/A), Manufactured Date: October 2023. The contact stated that the harness buckle was easy to release while attempting to secure the child in the car seat. The contact received notification of NHTSA Campaign Number: 24C002000 (Child seat). The manufacturer was made aware of the failure. The contact stated that the repair kit that was sent to repair the recall was an inadequate repair and did not address the safety concern regarding the harness buckle. The manufacturer was notified of the issue but offer no additional assistance. The contact was also denied a replacement car seat despite the car seat being under warranty.

I was driving along and got a warning to pull over due to low power. This is the third time this has occurred and is a well--documented failure point for this vehicle. I go in for "repair", things are checked and sometimes software is updated and then within months the problem returns. Very unsafe being stranded on a high speed, two land rural road at night. It has been flat bedded to the dealer and tomorrow I will here theri song and dance.

FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
On numerous occasions starting May 2024 and continuing through July 2025, my 2022 Hyundai Ioniq 5 displayed a “Check electric vehicle system” error upon starting the vehicle. In June 2024, Hyundai replaced the vehicle's VCM under warranty. In December 2024, the car wouldn't start. Hyundai replaced the 12v battery under warranty. In April 2025, the vehicle would not drive above 20 mph and warned of imminent shutdown while driving and Hyundai eventually replaced the ICCU under warranty. And in July 2025, Hyundai replaced the charging port under warranty. In all, the vehicle has been out service for 95 days while being repaired under warranty and most of those days I was not provided with a loaner vehicle. During the ICCU replacement, I was forced to rent a vehicle two separate times to get to work. Hyundai assured me that I would be reimbursed both for costs associated with the rental vehicles and the loss of use of my vehicle while under repairs, however despite multiple emails and conversations and having provided all requested documentation, I have received no reimbursement from Hyundai. Please assist me in obtaining reimbursement from Hyundai as soon as possible. Thank you!

SERVICE BRAKES
When coming to a stop on a slight incline, the vehicle will come to a full and complete stop and occasionally begin to roll backwards after half a 2nd without changing brake pedal position. If the brake pedal is not push further down, the vehicle will continue to roll backwards. I have tested this on multiple IONIQ 5 models with the same result (2022 and 2023). This could cause a collision if there is another car behind the problem vehicle. No warning lamps. Both vehicles have done this since new. Nothing is wrong with either of the vehicles according to multiple dealers.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
Ok.... So, if anyone reads about Hyundai Electric line.... Ionic series... they would know that since Day 1, Hyundai has had problems with their electrical system. It 1st started with the system never charged the onboard standard 12V battery. I had to purchase Jumpstart boxes, I couldn't run my car ever on acc bc since day 1, my car has never been charging the onboard 12v battery. This caused me to not be able to start my car on more than 5 occasions. I had to ask strangers for help at times, locked out of my car on the side of the street, in parking lots, driving to Auto Zone after a complete trickle charge didn't work bc battery is so drained. During this drive, my cars safety features wouldn't work correctly, everything blinking and i had to make it to Auto Zone to have to buy a new GSM battery. I feared for my life on that drive. Certainly a safety issue. When I asked Hyundai on numerous occasions, they said there's no way for us to test if the recall fix we did actually is helping the issue. So I had to buy my own DC volt meter. I took that car in 4 times to deal with this issue. Now, after my last visit to Holler Hyundai in Winter Park a few months ago, now my car won't charge at home. I tested it with the 2nd charger. F2 fault code on standard home charger. Red lights on my ChargePoint charger. Car charges fine at DC Supercharger (6 times as expensive). I have told Daytona Hyundai multiple times (General Manager knows me) about how I have taken this in to have this problem fixed on many occasions. The GM said he apologizes, doesn't know why it wasn't fixed, they were unprofessional aside from him making many mistakes. The original dealer i bought it from was a bad experience and I do not trust them at all and would not buy from them ever again. I have video and pics of spiders in my car/roaches, etc. Dealership didn't even respond after I emailed them pics. I have bought and owned over 30 cars. This definately needs attention

Car started issuing a burning smell, emitting a noxious burning smell through the air vents making it impossible to drive with the windows closed. The HVAC system had to be shut off. The Ioniq 5 and all E-GMP Hyundai vehicles have known issues with the charging port and ICCU (integrated charging control unit). This vehicle has had all previous recalls related to charging and the ICCU addressed, but it has still resulted in failure of the vehicle charging port. Dealership stated charging port needed to be replaced, but stated it would not be covered under warranty with now explanation provided despite the fact that this is still covered under several recalls.

The ICCU in the car failed. It immediately limited the speed of the vehicle to 25mph. There were no warnings, it happened all at once. I had to drive on the shoulder of the interstate to the next exit. Obviously, driving 25 on the shoulder while cars passed me at 65+ was not a safe situation.

STRUCTURE:BODY
Interior driver's side door handle broke off. The driver cannot open the door without lowering the window (electrically operated) and reaching outside to pull the exterior door handle. The car must remain of to do this (if off, the window cannot be lowered). I deem this to be extremely dangerous in the event of an accident when the car cannot be started; the driver is stuck in the car.

My EV’s ICCU failed. It has since been fixed and is not available for inspection. Yes, my safety was at risk because my speed was suddenly limited away from home and I had to get my family home. After a wait of about 3.5 weeks, the dealer confirmed it was an ICCU failure and replaced the ICCU about one week after that. There were no warnings until the failure occurred. I believe Hyundai’s ICCU problems are well-known, but want NHTSA to be aware.
