This things scares you to death because it happens on the highway.....and just like going to the dentist, it never happens when you are trying explain it to a mechanic.....here's what I've noticed:

It happens on the highway

You never know when it's going to happen

Window just pops open (ajar) not all the way up / interior lights also come on which makes things worse at night.

Mechanic teased me and said the car was haunted

I monitored the situation slightly and start opening and closing the window every 4-5 days which seems to have helped slightly (but I'm not sure)
