I have a similar issue on my driver's side door

since i purchase my 300 c i notice a noise coming from the pass'. side door and getting worst. notify dealer and i'm still waiting for call that the part is in. going on 5 weeks other then this love the car.
I too have a scary sounding creaking sound whenever I open and close the driver's door. The sound seems to correlate with the detents which hold the door at various levels of openness.
I showed it to the dealer yesterday and the guy said he had seen this once before on a 300C (Mine is a Touring, and 3 weeks old). They are ordering a new hinge from the factory, because that did the trick before. We'll see...
