Every time I get in the Leaf and press the start button the audio system also turns on even though it was off when I turned the car off. At first I thought I was mistaken about having turned it off, but I've verified several times that it was indeed off when I shut off the car. It's kind of annoying because when it happens as I'm backing out of the driveway I can't shut it off until I'm done backing up (the buttons are unresponsive while backing), not to mention the general annoyance of the radio turning on and blaring when I didn't want it on in the first place.
