I have the 8200. I always use my 1/4" foot, and I always set the machine to Mode 1, stitch 08, which automatically moves the needle to the correct position.
Does the needle move to any other position when you try? Or is it just not responding to moving right? I would call the dealer. Might be a solution they can tell you over the phone (before committing it to a service). At any rate, if it's practically brand new, it's probably under warranty.
