I bought my Clarity a few months ago, and I drive it mostly highway miles. Lately I've noticed that even on a full charge (ie, the charger stops because battery is full) the estimated EV range is only about ~40 miles, sometimes even less. I charge on 110V at home, sometimes on 240V at a public charger. Is anyone else regularly seeing far less than the stated 47 miles EV range? Any ideas why?
