Rapide windows unlocking suddenly

Hey everyone! Just purchased a MINT condition 2011 rapide with only 35k miles. Beautiful car but noticed something odd after having it for a week. While driving, the drivers side front and rear windows “unlock” and lower 1” as if i was going to open the door. This is occurring randomly as i am driving. Any suggestions on how to fix this? I live in miami and we get lots of rain and this would not be a good thing to happen in a big storm.
