NHTSA Complaint #11522379 — 2022 KIA EV6

I was traveling on a neighborhood arterial road, when I heard a load thunk that seemed to come from beneath the rear seat. Moments later, I got a "Check electric vehicle system" warning, followed by "Stop vehicle and check power supply" in the dashboard. After another moment, the power was reduced to a maximum of 25 mph. I turned on the hazard lights because I was no longer able to match the flow of traffic (45 mph). No accident occurred. I was able to limp the car home on slower side streets. At home, I eventually got a "12v battery voltage low" message and the car was unable to move. I had to have the car towed to the dealership. The dealer service folks diagnosed the problem as a failed integrated charging control unit (ICCU). This same problem has been reported by others in the Kia EV forums. Kia Consumer Affairs says 87 of those parts are on backorder in the US with no ETA from Korea. Apparently, the part needs to be manufactured; they don't have them available in a warehouse.
