I took my car into the dealership this morning. I took a "test drive" with a technician that lasted all of thirty seconds. We never even left the parking lot when he acknowledged that there was creaking all over the place. He said it was the door seals and that it's a known issue. Pretty awesome how they took ownership of the issue right away. The only negative is that I have a Pontiac Vibe as a loaner... booo.
I'll post another update once I get my car back (hopefully today or tomorrow).
