 We have a company car also, so whenever I don't drive the Prius for ten days, I find a dead battery! I've used up my AAA for the year already, and have an expensive repair ($120) from trying to open the back hatch- you are completely locked out! No one ever warned us about this! Don't go on vacation w/o getting your car a babysitter!!  Also, I want to complain about an irritating design feature: when driving at night, there is a bad glare, a green bar of reflection onto the windshield right where you look to drive from the the display! If the top frame of it was extended a little, like a hood, it wouldn't happen. And I can't fix it. Same problem in the daytime, gps screen needs shade- bleached out.
