They did replace something, the mechanic said it had something to do with the computer, but he just pulled out a part and put a new one in. When I asked what it was, he just said "oh, just an updated part" which I don't believe because typically companies don't activate recalls unless is pretty dam important, since it cost them a lot of money.
