I had the same problem and reported it to the dealer as well. They contacted Honda and the best they could tell was that the door seals needed to break in a bit and it would go away. I did notice a fair amount of "New Car Goo" around all the seals and the door to car sealing surfaces that I cleaned up to a mirror finish. The squeaking stopped when I did this. Maybe it was a combination of the two, I don't know. But it did go away.
Cheers!
