I've had two episodes recently where my Clarity was in Eco mode, with a full or mostly full battery and the gas engine came on inexplicably. The first time was several weeks ago. I was stopped at a light and all of a sudden the engine came on and stayed on for a mile or two after I pulled away from the light, before switching off and back into EV mode. As it should have never come out of EV mode while stopped, much less on a full charge, I had the dealer look at it and they ran a diagnostic and checked Honda's internal forums and found nothing. This afternoon, I floored it up a small hill in Eco mode kind of just playing around and the engine kicked in, as expected. But then it wouldn't go off. For the next 15 minutes, the car would not flip back into EV mode, even though I was driving 35 mph in Eco mode with 75% battery charge and using the regen paddles. Finally, when I thought I was going to have to pull over and turn the car off and then on again, it suddenly switched back to EV mode and then worked fine for the rest of the drive home (15 miles). Thoughts? Similar experiences?
