The rear window is leaking so much that when driving in the rain, the people sitting in the back seat were getting dripped on constantly, ( they were soaked at the end of the ride). You can physically see the dripping coming down on them. When this happens, the windows fog up badly and that will not go away. the header inside collects a good amount of water and that keeps it very moist in the cabin compartment. You have to wipe front window down often while driving, to be able to see where you are going!
