Owner complaint summary

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.
