While driving my car a warning flashed stating ‘check electrical vehicle system.’ Pulled over, contacted Kia of Abilene and asked if we could drive the car to the dealership. While on the phone another warning flashed »Stop vehicle and check power supply.’ Attempted to drive car, ‘Limp mode or turtle mode’ occurred and the max speed for the car was 25mph, sudden loss of acceleration. Made it home, which was approximately 2 miles away, and it seems like the 12V battery was draining quickly. Eventually the vehicle stalled at home and became unresponsive, no power. Contacted roadside assistance and the vehicle was towed to Kia of Abilene. All of this occurred March 29th at approximately noon. The dealership finally contacted us today, April 2nd, and notified us it was an ICCU failure and the part wasn’t available with no foreseeable time-frame for repair. The car is absolutely inoperable!
