As your car is a 2011 model, it doesn't fall into the recall section. It sucks, but really there's precious little you can do here apart from suck it up and get it sorted at your own cost. Legally, I don't see where you can go as your contract is with the supplying dealer not Nissan (when did you buy the car?).
I agree that I'd be mad as hell too and vow never to buy another, but that's the world we live in I'm afraid. Nissan really do not have a clue about customer service, especially on their sporty models unless it's a GT-R.
