I came back to find the passenger side window open. Must be related to the faulty anti-pinch function. There's a problem with one-touch closing. The window goes up - hits the top - then goes down to 3/4 open. My old car had full-closure, so i always forget to close the windows before getting out. I used the key fob, and because I was driver-side, I walked off and didn't see the passenger-side window go back down. Have to remember to manually close the windows now - but at least they stay closed.
