My 2017 Civic has done this
My 2017 Civic has done this twice during a severe storm. Neither key fob was accessible during the time, but when I walked out the next morning all four door windows and sunroof was half opened. The whole inside of the car was drenched and took two days to dry out. This car is doing it during an electrical storm without manipulating the key fob. Very irritating. I am now having to cover my car just in case it happens again.
