My caras ICCU (Integrated Charging Control Unit) failed, causing the 12-volt battery to stop charging and die, leading to a loss of power to the vehicle, resulting in the vehicle being completely immobile. I was driving on a busy road when all of a sudden the car started to slow down dangerously which almost caused the cars behind me to crash into me. The car’s screen said it was entering limp mode. Then the vehicle completely stopped. I was stranded far away from home. I had to call a tow truck to tow the car to the dealer. The problem was confirmed by the dealer. The dealer confirmed the ICCU and 12-v battery failed. The dealer took 3months to repair the car.
