1. Last night I plugged in my Karma and when I came back this morning it hadn't charged. I'm not sure why, but it'd be nice to have a little LED on the outside of the car that tells me Red when it's charging and Green when it's done charging. (Maybe "Blue" for "Car is parked but fans are on and cooling down the interior of your car for you"?)
2. I'd like to be able to turn off the "press lock twice for rolling all the windows down". Who uses that? I find that it happens to always be hit by mistake (or children) during rainstorms.
3. A pull down (or sideways) screen on the windshield to protect the leather interior from sunlight. This would look way more sophisticated than those dashboard protectors you can buy. Also, there is nowhere really in the Karma to store a dashboard protector.
