there is a thread on the power lift gate, so search and you'll find your answer on that, has to do with a firmware update to adjust the sensitivity of closing.
for things you can't push on the screen that are locked out you should be able to control via voice, but as far as i'm aware there isn't much that locks you out.
and for the update. i've had my car for about a month and a half now and i received my update in the mail 3 weeks ago. have you registered on syncmyride.com?
