Our 2025 Hyundai Ioniq 5 has been sitting unrepaired for almost five months due to a complete lack of availability of an essential replacement part (front bumper lower molding part number 86569PI000). The car was involved in a minor collision on [XXX], and although no one was hurt and the airbags did not deploy, the vehicle has remained unrepairable and inoperable. The car sensors can not be calibrated without this part, thus affecting all front sensors of the vehicle. Both the Hyundai-certified repair facility and our insurance company have confirmed that the necessary part is on national backorder with no estimated date of arrival, despite extensive efforts to source it — including looking on eBay and through nationwide networks. This was also confirmed by Hyundai Customer Support with whom we opened case [XXX]. The part involved is necessary for proper calibration of front sensors of the vehicle. We are continuing to pay on the lease while the car sits undriveable and depreciating. This has placed a major financial burden on us and raises broader safety concerns. Hyundai is apparently unable or unwilling to supply parts for its current-year models, which may compromise the safe restoration of structurally- or electronically-damaged vehicles. We respectfully request that NHTSA investigate Hyundai’s inability to supply safety-critical parts for its 2025 models, and determine whether this systemic delay poses a risk to consumers and undermines post-collision safety standards. The repair shop is Advanced Collision Repair in Escondido, CA, 760-741-7565. The shop’s manager is John McLure.

1. The Integrated Charging Control Unit (ICCU) and associated high-voltage harness/fuse appear to have failed. According to the dealership, both the ICCU harness and a high-voltage fuse are being replaced. The vehicle is still at the dealer for repairs and can be made available for inspection upon request. 2. While merging onto a freeway on-ramp after charging at a Tesla Supercharger in Barstow, California, the vehicle suddenly stalled, losing all propulsion power. This occurred in live traffic while attempting to accelerate, putting me at significant risk of a collision. I was forced to stop the vehicle on the on-ramp and eventually had to call a tow truck. The situation was hazardous, as there was no shoulder to safely exit the vehicle and other vehicles were traveling at high speeds. 3. Yes. The issue was confirmed by the authorized Hyundai dealership where the vehicle was towed. The dealership stated that the ICCU harness and a high-voltage fuse are being replaced under warranty. However, they have also indicated that the required parts are backordered, and no ETA has been provided. 4. The vehicle has been inspected by a Hyundai dealership technician, and Hyundai Motor America is involved in the case. It has not been inspected by police or insurance representatives. Hyundai Customer Care has acknowledged the issue and is in contact with me, but a resolution has not yet been reached. 5. Yes. Approximately 5 to 10 seconds after finishing DC fast charging at the Barstow Tesla Supercharger, the vehicle displayed a brief warning message related to the charging system. Unfortunately, the warning disappeared quickly before I could take a photo or read it in full. Immediately after, as I attempted to enter the freeway on-ramp, the vehicle stalled.

I purchased this car this week. The vehicle is equipped with a safety feature called Forward Attention Warning (FAW). Its purpose is to monitor the drivers attention (eyes??) and trigger an alert when the drivers attention is distracted for a period of time. I took it for the first time on a 150 mile trip. During the trip, the FAW alarm was triggered constantly. I tried changing my head position, taking my glasses on/off, changing my hands holding the wheel, etc. Nothing seemed to matter. It is not only a nuisance, but it causes other automated functions to be disabled. I was able to partially turn it off, but it still caused misfunctioning of other auto driving functions. Its not just a nuisance, its a hazard. If it cant be fixed easily, Hyundai should at least give the operator the ability to completely disable it.
