Call Gm customer service. Get the sales guy involved. Get the service manager involved. Make a scene in the service department and the show room, that you just bought a new vehicle from them and they will not or can not fix it. It only has 2800 miles on it. The longer you have it the harder it will be for you to get them to do something about it.
