Just another reason to do the work yourself or use an independent garage. Yes, I know that for a factory recall you have to go to a dealer, but limit you visits. I suspect a bad situation would develop very quickly should they try to pull a stunt like that on me. FWIW I was very paranoid when I lived in Kalafornia [driving an older van] for that very reason. By the same reasoning though I seen a few vehicles that made me very uneasy knowing they were being driven on the streets the same time I was on them. They were not about to see a dealer though.
