1) This is the second occurrence of this issue within the past 12 months. While driving, my EV displayed various blinking lights and a “Check EV Connection” message, followed by a “12v Battery Critical” warning. The entire system began shutting down in the middle of the road. I managed to pull over before the car completely shut off. 2) This malfunction posed a significant safety risk to me and others. The rapid deceleration and uncertainty of an imminent shutdown almost caused an accident, either from other vehicles crashing into me or from my inability to stop in time, potentially hitting another car. I have faced this life-threatening situation twice within a year due to the same issue. 3) The problem was confirmed by my dealership less than a year ago, and my car is currently being towed back to the dealership for re-inspection of the same issue. 4) The vehicle and its components have not been inspected by the manufacturer, police, insurance representatives, or other parties for the current situation. However, the manufacturer issued a recall for this problem last year AFTER my initial report, incident, and repair. They claimed to have fixed the faulty issue or replaced the necessary parts, when my vehicle was repaired less than 12 months ago. Despite this, I am experiencing the same critical problem again. 5) During the incident, my entire panel started blinking with a “Check EV Connection” message, followed by a red warning sign indicating a 12v Battery Critical Failure warning. The system then went black, and the panel continued to blink white and black consistently while parked. The car cannot be started or moved.

Less than 48 hours after getting the latest Integrated Charging Control Unit (ICCU) recall performed (Hyundai Recall Number 272, NHTSA Recall Number 24V-868), the ICCU on my car failed. This resulted in the 12V battery no longer being charged by the EV's main battery, and the car entering "Limp-Home Mode", limiting the car's speed to 20mph. Error messages include "Check electric vehicle system" and "Stop vehicle and check power supply". These messages appeared when the ICCU failed, not before. ICCU failures are well known with this car, hence the recall. However, there is anecdotal evidence in the Ioniq 5 Facebook forums that indicate that the ICCU failure rate INCREASES on cars that have had the recall performed. Hyundai and the NHTSA need to examine the failure data to see if there is a cause-and-effect relationship between recall repair and increased failure rate, or if the failures observed by the community are just coincidental.

Turning into my driveway one evening, the car displayed the "Check Electric Vehicle System" alert on dash. The following morning while backing out of the driveway to wait for a tow, the alert changed to "Stop vehicle and check power supply". Got car towed to dealer, and after diagnosing, confirmed that ICCU failed. Car has been at the dealer for almost 2 weeks at this point, and the part is still back-ordered with no ETA, according to the service advisor I have been working with.

I took my Hyundai in twice to a local dealership for the recall to be fixed. They failed both times to remedy the situation, and said they would handle it again at my next scheduled service appointment. A few weeks later my car suffered from the ICCU failure and I was stuck without a working vehicle. I had my car towed to the dealership 20 days ago but they have no ETA on the part needed to fix the recall.

I had the most recent recall (code 702 I believe) done on January 13th. I believe the recall was an NHTSA required recall and after the software update that was part of the recall my car will no longer charge. It has been with the dealer since January 15th with no resolution in sight. The software update was I believe the 4th such update intended to prevent a part called an ICCU from failing. It took 4 business days but the dealer Hyundai of Roseville confirmed the ICCU needs to be replaced and they don’t have an ETA on when the part will be shipped. Online I have seen reports of the same thing happening to others and the ICCU repair process taking 1-2 months.

Electrical system failure. Available for inspection upon request. While driving, warning appeared on dashboard. Warning said, "Stop Vehicle and Check Power Supply" The safety of vehicle occupants and others on the road was put at risk. I lost control of the vehicle in the middle of traffic due to the loss of electrical power. The problem has been confirmed by San Leandro Hyundai as part of the Safety Recall for the Integrated Charging Control Unit, Recall number 272. NHTSA Recall number 24V-868. The recall repair was completed but the ICCU was not replaced and is still defective. A few minutes prior to the eletrical failure a warning message appeared on the dashboard. The warning message said, "Stop Vehicle and Check Power Supply". First appeared on Saturday January 11th at 4PM (PT).

On December 22, 2024, I went out at 8 AM to have breakfast with my dad. On the way back, I noticed my car starting to slow down, and the "turtle mode" activated. Normally, this mode only occurs when the battery level is under 1%, but my battery was at 75%. As I tried to park in a safe location, the car suddenly lost power and displayed a warning instructing me to stop due to an electrical problem and to contact service. I was able to safely stop at a small shopping center plaza and called Hyundai's towing service. When the towing company arrived, they found they couldn’t turn the car on and had to use a wheel-lift tow method. Unfortunately, I had to wait nine hours for the car to be towed. The car was dropped off at the dealership on December 22, 2024, but it wasn’t checked until December 31. By the end of the first week or early in the second week of January, I was informed that the replacement ICCU (Integrated Charging Control Unit) had arrived. However, due to the dealership's schedule, they said they wouldn’t begin the installation until the following Tuesday, with hopes of completing the work by the end of that week. This incident was especially frustrating because I had already experienced an ICCU failure in January 2023, just nine months after purchasing the vehicle. At that time, no one could explain why the ICCU component had failed, and now I’m facing the same issue again.

POWER TRAIN, ELECTRICAL SYSTEM
The vehicle has no power whatsoever. Upon approaching the vehicle, it did not unlock. I used the physical key to open the drivers door. I then tried starting the vehicle only to have the gauge and center display flashing on and off with a red warning That the 12v was dead, to pull over and top immediately then the displays turned off. There are no lights or power to the vehicle no whatsoever. It cannot turn on any of the interior lights or even power door locks. This means only the front doors can be opened or locked and the vehicle will obviously not move. The 12v battery system has been a continuing issue with the vehicle. It has been repaired and the subject of several recalls during my short ownership and is still a problem. Due to a blizzard, I have been unable to have the vehicle taken to the dealership and have been without transportation for 3 days already with no clear resolution from Hyundai.

The ICCU on my Ioniq 5 failed without any warning from the car or mobile app. All recalls were performed on the vehicle prior to it failing. I was unable to charge the vehicle on level 1 or level 2 charging. The dealership replaced both the ICCU and fuse on the vehicle.

12 V battery died after being plugged in to charge overnight. The 12V battery was replaced in May 2024 due to a similar issue. It seems that the ICCU recalls and software updates have not been fixing the problem.

SEATS
Passenger side rear seat (40% side) is missing all mounting bolts required to secure seat to vehicle. I purchased the vehicle as a preowned unit and noticed squeaking and a rattle coming from the rear seats. Upon inspection, I discovered that the seat is only resting on the floor and with little effort the seat can be dislodged.

Unknowingly my cars ICCU failed. I went to charge my car on December 23. The EVSE then immediately tripped the breaker. The EVSE gave an error code of a stuck relay fault and made the EVSE unusable. This happened to 2 different Juicebox chargers and both are not permanently disabled and need to be replaced.

Hyundai has absolutely dropped the ball on this Ioniq 5's ICCU and 12V battery issue. After numerous recalls to fix a hardware problem through a series of software fixes that don't work and refusal to give a loaner for loss of use, I would like to pursue a buyback option for this vehicle. On Tuesday, [XXX], I went to Napleton Valley Hyundai in Aurora, IL to complete RECALL CAMPAIGN #272 NHTSA RECALL # 24V868000. After the recall, my 12V battery went dead on Wednesday, [XXX] and had to be towed to dealership. Their only solution was yet another software update and then charge the 12V and said it was ready for pickup on Thursday, December 5. I told them then to also do a wheel alignment and they said during that process, the 12V battery went down again. They then charged it back up and gave it back to me and said it was good. I encouraged them to pursue a better solution but they had no interest. So, it was picked up on Friday, [XXX]. On Saturday [XXX], the 12V battery went dead again and will have to be towed back to the dealership. Over the phone, my service advisor said it would have to be charged and released. If this issue then happens again, then a replacement might be considered. Calls to Hyundai North America headquarters have not yielded any results and they claim they need 3 business days to assign my case while I have no working car.

Hyundai issued TSB 22-01-094H for my vehicle which is an update to the battery management system,, but after 4 attempts Hyundai dealerships have still not been able to complete the TSB. Hyundai corporate has also not helped after multiple cases. After many hours of research, I have determined that my vehicle's BMS software was updated to an intermittent version (version 700x) that does not support this TSB via automatic update, and the correct BMS Rom (version 540x) must be selected manually, which the dealerships are unwilling or unable to do.
