Windows mysteriously opening spontaniously

The front driver’s and passenger’s side windows on my 2006 Murano, on at least 6 occasions, opened by themselves while the car was unoccupied, turned off and parked. I live in a city and have no garage, so my car is typically parked on a street and can easily can be stolen if the windows are open. Also rain and snow have entered the car on two of these incidents. I’ve taken the car to a Nissan dealer and they could not find any problem with the electrical system. Has anyone had a similar problem? If so, what solution have you found? Thanks for suggestions.

Can your windows be opened from the remote? If so, are you certain you’re not accidentally pushing the buttons in your pocket while you’re in the house?
