After driving, when i put on park, turn off vehicle and remove key from ignition after I open driver door all windows roll down. Please help

 

It may be that your fob is pressing against something in your purse as described below. If not you need to take it to a dealer.

The RX my wife had would do the same thing, found out it was the key fob, if the unlock was pressed repeatedly all of the windows would roll down and the sun roof would open, thought it was a malfunction til I found that it is mentioned in the owners manual, is it programmed that way. Just like if you roll up a window accidentally on your hand it will automatically roll the window down just as soon as it senses a high load before fully closing.
So keep the key fob away from things that might be rolling around in her purse.
