    I've had the car a little over a month. First 1000 miles were smooth (55mpg), but I have noticed that the ICE kicks in a lot more frequently now. I might be driving it incorrectly, but I've noticed my mpgs drop to under 50 for the last 800 miles driving the same commute. For an extreme example of the revving: I go to the store. Get out of the car for as little as 10 minutes after the car has been driven 15 miles or so — and even though the battery is more than half way charged, the ICE kicks once I start moving from my spot.

    Even if I'm just moving from one part of the parking lot to another going less than 10 mph. When I let off the gas, the ICE continues to run even after I come to a stop.

    Now I know it's getting colder (highs in the lower 50s these days), so I expect this in the morning after it sits out all night. But I don't remember this happening when I first got it (granted, it was warmer in mid Sept here).

    Am I nitpicking here? Do I need to learn how to drive this car better?

    I think its the weather. Look up grill blocking. If its cold out, the heat really gets sucked out. I could be wrong, but in the high 30's my ICE came back on after driving 1.3 miles at 45mph after I sat at a light for 1 minute.

    I'd go with weather being the reason as well. Now that it's high 50s and low 60s in the morning here, I notice the ICE does stay on longer or come on more frequently.

    Another vote for the weather. Also keep in mind that the ICE works more when you have the heat on.
