I have an 07 4dr and the top has yet to leak. I don't have power windows and noticed the windows dropped during the winter when I had the doors on. They didn't drop enough to appear open but enough to allow water in when I brought it through the car wash. I was lucky enough to be in the car and catch it before too much water got in. Now I always have to roll them up an 8th of an inch when I wash it.
