I am new to the forum and have had a 2013 Cmax SE for about a year without any issues. Twice now I have found in the morning all my windows down. Once, yes during a rain storm! The second thank goodness high and dry. I absolutely know that when I last left the vehicle both times the car windows were up (They are tinted so its easy to tell) and the car locked. The only theory I have had so far besides some electrical failure is the FOB. Is there a combination of buttons that pushed accidently will trigger all the windows to go down. Very Strange!! Other than that the car has been fantastic as its my first hybrid.
