Sorry to hear you were victimized. Having had a car stolen under my nose a few years ago I know you must feel fairly ticked off. Yours is the first story I have heard about that with the Titan, but I have heard about the problem on other types of vehicles that have a similar express window down feature when the key is turned in the lock. The rear sliding window on a lot of trucks can also be popped out with little or some effort to gain access (although limited to the size of the window). I try not to leave anything in the truck that would tempt someone to break in it, but a motivated car thief is hard to stop.
