NHTSA Complaint #11624715 — 2024 KIA EV9

I was driving down the highway at approximately 60 mph with approximately 40% charge to the high voltage battery. While moving the car suddenly stopped accelerating and switched to neutral automatically. The instrument panel provided no audible alerts of a problem and in relatively small text stated "check electrical system" The brakes and the rest of the car's electronics worked such as turn signals and warning lights. We were able to coast and pull over to shoulder of highway and stop safely, but losing acceleration in middle of highway suddenly was very scary. Car is currently at dealer awaiting to be diagnosed.
