This may sound like a very stupid question but I just want to make sure.. are you sure you're not confusing this rattling sound for the sound that the car makes when switching to 4 cylinders? In V4 mode it will sound like its puttering and slightly rattling, but its completely normal and of course..this only happens when cruise at the same speed.
