Well the dealership just called me back. They basically said: Well, we checked it out and everythings fine so you are all set. Are you kidding me? I guess because it didn't do it for them. But come on, like I made this crazy car convulsion up? I'm not sure what to do because the noise only lasts about a minute so I can bring it back in if it does it but they won't hear it. They claimed if it does it there they can diagnose it then because their scanner will show it, but then why didn't it show it when I brought the car in within an hour of it happening? I hope others post here and let me know what they did. Or get more attention to this issue so I get a better response than I got.
