I live on a hill and often start my drives going down a fairly steep winging hill, about a half mile from top to bottom. Sometimes the engine starts before I get to the bottom of the hill despite having a full charge. I have found that it I shut of the car and restart it that it runs in EV mode again, albeit with a shorter blue line. I'm not clear why that happens, I'm not trying to force it to regen, but I do use the brake on the way down the hill. I have tried using the regen paddle and it happens also when I do that. Is this normal? Is it because its trying to regen on a full battery? The Volt I previously had would just add a couple of miles to the range but would not cause a problem.
