ok , my 2 week old lt2 has had a few vibration sounds coming from under passanger side under hood or car. took it to dealer and had a service guy ride with me and he thinks it might be a heat shield. didn't have time to put it on lift. anyone had this happen yet ? not sure if cold has anything to do with it or not........

This post should be under the Problems/Dealer Service thread, but regardless, what do you mean by vibration "sounds"?

Some of us are having a drivetrain vibration/shudder that is a physical shake under acceleration/cruising, but I have not yet heard of anything in relation to a vibration sound. More details? When, how, what is it like?
