I was driving my vehicle and it suddenly lost all power. I had to stop in an unsafe place on the road and wait to get my car towed. I had previously been to the dealership three times to have recall and software updates done that we’re supposed to fix this issue. Apparently the ICCU to be a terrible problem.

Vehicle was involved in a double fatal. After viewing of dashcam video I suspect a malfunction of the vehicle may have occurred. The video appears to show the vehicle continuously accelerating despite the sound of what may be the driver attempting to repeatedly mash on the brakes. EDR records do not coincide with the dashcam video.

We are reporting a suspected thermal runaway incident involving our recently purchased used 2023 Hyundai Ioniq 5 and have significant concerns regarding the vehicle's safety. **Vehicle Information** * Purchased XXX, 36,662 miles * Clean inspection and no accidents per Carfax **Incident Timeline – XXX** Between 6:00 and 6:30 PM, while traveling northbound on [XXX] just past the [XXX] exit in [XXX], the vehicle struck a white piece of road debris that appeared flat, similar to Styrofoam (video available). There was no immediate loss of vehicle function. [XXX] The vehicle was then moved to the driveway for inspection after a low coolant warning appeared. Damage to the underside near the driver's side and observed blue coolant leaking from the area. The coolant reservoir under the hood was empty. Based on online guidance advising against driving a vehicle with a coolant leak, we decided to leave the vehicle parked in our garage overnight and arrange a flatbed tow to a Hyundai dealership the following day. The garage door was closed, and the vehicle was **not charging**. At approximately 8:10 PM, a burning smell was detected inside the home. Upon opening the door between the house and garage, smoke was observed. The family immediately evacuated, and XXX was called at 8:12 PM. The fire department arrived at approximately 8:18 PM and found the garage filled with smoke. At 8:30 PM, firefighters removed the vehicle from the garage. At 8:35 PM, flames were observed beneath the vehicle. Firefighters applied water directly to the fire until 11:00 PM, after which the vehicle was removed. [XXX] [XXX] [XXX] Manufacturer was contacted; denies any liability due to debris. However, we believe inadequate safety design contributed, including soft protection shield and poor location of coolant.

The vehicle repeatedly displays a "Stop Vehicle and Check Brake System" warning together with an ABS warning, accompanied by a loss of normal braking response. On XXX, while driving at approximately 60 mph on I-85 northbound near Exit XXX in [XXX], the warnings appeared and the brakes did not respond normally. I was maintaining a substantial following distance, and the braking system restored itself before I reached the point of needing to brake hard, so no crash or injury occurred. Had hard braking been required in that window, I do not believe the vehicle would have stopped as commanded. This is a recurring fault. The vehicle, purchased certified pre-owned and still under the Hyundai factory warranty, has been taken to the dealer (Ed Voyles Hyundai, [XXX]) three times for the same condition. On the first visit the Integrated Electronic Brake (IEB) unit was replaced; on the second, the Smart Junction Box was replaced; on the third, the dealer removed an aftermarket tracking device wired to the data link connector and referenced Hyundai TSB 24-GI-011H, representing the problem as corrected. The braking-loss event on XXX occurred after that repair. The vehicle has been out of service approximately 30 days total. Because the failure is an intermittent loss of braking response at highway speed, I consider it a serious safety hazard and no longer drive the vehicle.

The ioniq 5 highway driving assist, which steers the car and keeps it centered in the lane, will disengage without clear warning - the small green steering wheel icon (which is at the top of the dash cluster) simply becomes grey and blinks, but there's no audible chime to indicate that the car has disengaged the steering assist. I have had multiple times on the highway where it disengaged and I don't notice (because I am looking at the road, not the dash) and one time on the highway it disengaged during a turn and hit the rumble strip, causing me to swerve back onto the road. My hands were on the steering wheel and I was paying full attention, but I was expecting the car to handle the turn, and it just disengaged without me noticing. Had there been another car in the middle lane or I reacted slower, it's likely a crash would have occurred. This has been documented as well on Reddit and confirmed by multiple owners, who have mentioned they have disclosed to the manufacturer: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. What component failed, and is it available for inspection? The Integrated Charging Control Unit (ICCU) failed. The vehicle is currently at the dealer's service center, so the failed component is available for inspection upon request. 2. How was your safety or others' safety put at risk? After parking and re-entering the vehicle following a grocery stop, the vehicle displayed "Check Vehicle Electrical System" followed by "Check Vehicle Power Supply" warnings. This occurred without warning while the vehicle was in normal use, and the vehicle had to be towed since it was no longer driveable. The sudden, unannounced failure of the electrical/power system created a risk of being stranded in traffic or in an unsafe location had the failure occurred while driving rather than while parked. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The vehicle was towed to the dealer's service center, where the Hyundai-certified service technician confirmed the ICCU failed and informed us it needs replacement. 4. Has the vehicle been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by the dealer's Hyundai-certified service technician, who confirmed the ICCU failure. No additional inspection by Hyundai corporate, police, or insurance representatives has occurred at this time. 5. Were there any warning lamps, messages, or other symptoms prior to the failure, and when did they first appear? No warning lamps or messages appeared prior to the incident. The first symptoms were the "Check Vehicle Electrical System" and "Check Vehicle Power Supply" messages, which appeared suddenly upon re-entering the vehicle after a grocery stop, approximately one week after purchase (used) at roughly 8,000 miles.

OnXXX, as we approached what I call the 6 o’clock position of a round-about in [XXX], we had braked almost to a full stop (0-5 mph) to wait on the car ahead of us to enter the round-about when we felt increasing movement. Despite braking, to wait on that car, our car with increasing speed started shoving that car into the circle. Fortunately, he was able to drive away from us, but that car had been damaged on the back and right side. With that obstacle out of the way, our car rapidly and exponentially increased speed - all while we were fully braking. Two witnesses said they saw our brake lights as we sped along. We hit the curb as we approached the 12 o’clock exit, and that turned us so that we crossed both lanes of the road and headed towards the far sidewalk and storefronts. When we hit that curb it pushed us diagonally to face the street again. Hard to estimate but we must have been doing 50 mph when we hit a very large brick planter and we finally were wedged to a stop when we slammed in between two vehicles parked parallel to the sidewalk. The motor ran for a few seconds after we stopped, and finally quit on its own. We KNOW the brake was applied the whole time; there were no visual or audible alarms from the car as we entered “UNINTENDED ACCELERATION”. Despite the incredibly strong impact (our car has been deemed totaled) the front air bags did not deploy. Only the driver’s side curtain deployed. The bumper of the parked transport van on our front left was damaged, and the small SUV on our front right was deemed totaled. No people were in those two parked cars; the first car was hit at the initial slower speed so those people were not injured. By some grace, no pedestrians were in our path or they would surely have been killed. The driver of our car (my husband) was miraculously not injured, but CT scans and x-rays showed I had several contusions and a fractured tibia that will require surgery due to brake, propulsion, no air bags.

Car indicated 12v battery was critically low and that I should stop safely. I was just starting it in a parking lot. This is a classic ICCU failure and the car is up to date on all recall updates. The car requires manual key unlocking for outside access at this point, and the rear hatch is only unlockable using the manual release mechanism which is recessed into the rear hatch and needs the key. The back two doors cannot be opened at all, from either direction and the handles don't work when the electrical system has failed and the child lock was engaged accidentally when it happened. This legitimately terrifies me for anyone traveling with back seat passengers who need quick exit. There isn't one.

The Integrated Charging Control Unit (ICCU) failed on my 2023 Hyundai Ioniq 5. The vehicle stopped charging prematurely overnight via AC Level 2 charging and then refused to charge again at all. The ICCU is responsible for maintaining the 12V battery by topping it up during normal operation. No warning or check engine light came on, I was only made aware when I attempted L2 charging and the car would refuse to take the charge. I understand that with a failed ICCU, if I'm unaware of the failure (e.g., relies solely on DC fast charging which bypasses the ICCU), the 12V battery can deplete without warning while the vehicle is in motion, potentially causing sudden loss of vehicle systems including power steering, brakes, and other safety-critical electronics. The vehicle was parked at the time charging failure was discovered. No injuries occurred.

My Hyundai IONIQ 5 has repeatedly lost 12V power and shut down. The vehicle had to be jumped by AAA multiple times. After being restarted, it died again, and after two days of use it was dead again. I am concerned this is related to the known ICCU / 12V battery charging issue affecting IONIQ 5 vehicles, which can cause loss of motive power or make the vehicle undrivable. The vehicle is currently at Hyundai Southern States in Raleigh, NC for diagnosis and repair.

While charging my vehicle at home using a level 2 charger, the ICCU failed. When it failed, it caused a power surge and my level 2 charger “exploded.” It also caused the master breaker to trip, cutting the power off to my entire house. The vehicle no longer charges, will not drive over 25mph and has to be towed to a dealership for repair. Also, the level 2 charger is fried and no longer works.

On XXXXX, while parked at a campsite approximately two hours from my home, the vehicle displayed an “electrical failure” warning on the dashboard. The vehicle had been parked for less than 20 minutes when this issue occurred. I contacted Hyundai customer support that same evening to report the problem (Case #XXXXXX). On April 4, 2026, the vehicle was towed via Hyundai roadside assistance to Winner Hyundai in Dover, Delaware, where Tracy is my current point of contact. This situation left my family of four, along with our belongings and pet, stranded without transportation. Despite significant effort, we were unable to secure a rental vehicle in the Dewey Beach area, even after contacting multiple rental agencies and the dealership directly. This was later resolved, and I am currently in a rental through Enterprise; however, the stress and uncertainty of potentially being stranded was significant and unacceptable. While at the dealership, my wife witnessed the tow operator unloading the vehicle without proper equipment to safely lower it. As a result, the vehicle’s hitch made forceful contact with the pavement and became lodged. Multiple dealership employees observed the incident. After considerable effort to free the vehicle, it was released abruptly and rolled into another vehicle on the lot, causing additional damage. An argument then occurred between the dealership owner and the tow operator, which my wife was forced to witness.

On June 8, 2023, the Office of Defect Investigation (ODI) opened PE23011 to investigate allegations of loss of motor power on model year (MY) 2022 Hyundai Ioniq 5 vehicles. Some consumers reported loss of motor power immediately after a warning lamp illumination or reduction of motive power while the vehicle was in motion. This investigation found that the Integrated Charging Control Unit (ICCU) may be subject to various conditions such as overcurrent, overvoltage induced at the end of charging, and certain thermal loading during operation that can damage its internal components and open the ICCU fuse, resulting in an inability to charge the 12-volt battery. The vehicle could eventually lose all motive power, increasing the risk of a crash. In July 2023, Hyundai issued a service campaign to address certain MY 2022-2023 Ioniq 5 and MY 2023 Ioniq 6 vehicles that may have low 12V auxiliary battery charging occurrences due to an ICCU fault and may set the DTC P1A9096 “DC/DC Converter Input Voltage Sensor Fault”. On March 15, 2024, Hyundai filed Safety Recall 24V-204 for 98,878 MY 2022-2024 Hyundai Ioniq 5 vehicles and MY 2023-2024 Hyundai Ioniq 6, Genesis GV60, Genesis GV70 “Electrified” and Genesis G80 “Electrified” vehicles. The recall remedy provides an inspection, and if necessary, a replacement of the ICCU and the associated fuse. The ICCU software reduces the risk of overcurrent and implements voltage peak reduction at the end of EV battery charging. The recall also includes a software update that revises the electric water pump operational threshold to reduce thermal loading during charging and driving. In view of the recall action being taken by Hyundai, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
