Find/borrow/buy a diagnostic scanner. See if the car is throwing any codes. Post them here and I'm sure someone will help you figure out what to do next.

It can be challenging and time-consuming finding loose stuff that rattles when you drive. Can you hear it more clearly when you drive around with the windows open? If no, try looking around the interior first, then the engine bay. If you don't find anything suspicious there, then I would get the car up on a lift and go through the entire underside from front to back, checking for loose wiring looms, hoses/clamps, exhaust hangers, everything.
