My electric car lost power while driving with no warning. It came to a stop in the middle of the road and a message came on the screen that said ‘Stop vehicle and check power supply’. There was no advanced warning and I had to have the vehicle towed to the dealer. Upon inspection by the dealer I was told the ICCU unit failed and needed to be replaced. The dealer stated the the part was on backorder and there was no ETA for the part. Thankfully I was not driving on the freeway or I may not have been able to get the car to the shoulder. It was a very scary thing to lose all power in the middle of the road.
