Every time I step out my vehicle I hear noise of the lock/unlock system, headlights come on, windows roll down, and doors unlock by themselves. Sometimes, the vehicle does these things after I have run upstairs; I usually watch thru one of my windows and, voila!!!, I see my windows had rolled down by themselves and my headlights are on. Then I have to come down the stairs and start the process of securing my vehicle again (several times) and wait until I'm sure it will stay that way. One night it was so creepy (watching my vehicle doing these things all by itself) that I almost take off running.
