I PM'ed SocalTech and here's what he had to say about this issue:
The door seals tend to creak a lot on these cars. Depending on production date, you either have to replace the door seals, apply teflon tape to the door frame, or both.
Hope that was helpful. I went ahead and e-mailed my CA (as I don't have an SA yet) to make an appointment for next week. I'll let you know how it goes.
