Hi. New owner. Purchased 2019 Clarity brand new a month ago. Weird thing happened yesterday. Driving on the freeway at about 68mph EV mode. About 40 miles left on battery. 5 people in the car. Suddenly EV mode turns off. HV does not show up on the dash either. So I didnt even know what mode the car is driving in. Pushed HV button a couple of times, but did not go back to EV mode. About 5 minutes later the car switches to EV by itself. I dont understand what happened. Never happened before on the freeways, even at faster speeds. The only difference was that the car was carrying 5 people. Could the weight be the culprit?
