Welcome to the forum
@Newtali.
There is an issue with the windows apparently opening by themselves which is (usually, possibly always) caused by the driver (or maybe a passenger) accidentally touching the window controls when they get out of the car. The positioning of the controls seems to be a bit non-optimal in this respect. However I haven't heard of them moving by themselves when the car is actually locked or unlocked.
Are you absolutely sure this isn't a case of someone touching a window switch?
