Yep, I'm having the same problem with the rear hatch. It won't close fully without a lot of force. It closes easily when a door is open. I had the same problem with my C6 until the seal ruptured. It worked great after that. Not a good solution! I plan to be patient with the C7 for a while, but I do intend to follow up at the time of the first service if it has not become easier to close.
