   ICCU failure. I charged overnight at my home L2 charging as usual. I backed out of my garage and heard a loud pop. Almost immediately an “check electrical” warning came up. The car went to turtle mode and then completely died. The car was towed and I was informed the ICCU needed to be replaced. The car had all previous checks on ICCU performed (per mailed recalls) and was updated and passed each time.

   The ICCU unit failed. The message "Check Electrical System" appeared on the instrument cluster. Low-voltage battery voltage was 12.0V and vehicle speed was limited to 60 mph. Maximum speed was gradually reduced to 30 mph over a period of 40 minutes (voltage was 11.5 V) with minimal 12V loads. I pulled over and called a tow truck to the nearest service center. Kia confirmed the ICCU was defective and replaced the part under warranty.

Vehicle then displayed "Stop vehicle and check power supply,"…
