NHTSA Complaint #11567790 — 2022 HYUNDAI IONIQ 5

I started the car, and saw a "Check Electric Vehicle system" alert on the dashboard, and began driving. I was not far from my home, when I saw several messages saying "Stop Vehicle and Check Power Supply" - and the car began slowing and becoming unresponsive while I was in traffic. With my wife and infant son in the car, and being less than I mile from my home I was able to proceed cautiously and make it there. This is likely a known flaw in the integrated charge control unit of this model, which was subject to a voluntary service bulletin put out by Hyundai. I took care of the recommended service and firmware update in September 2023, but it did not prevent this electrical system failure - the service bulletin should have advised replacement instead of putting my family in danger without any warning.
