Re: Rattling under hood
It could be a number of things, from engine pulley, to a loose component - use your hands and make sure air intake, wires, relays are all snug and attached somewhere. You might want to phone a local dealer and give them your VIN, then they can tell you if any TSBs have been issues for your vehicle and if any have been performed.
I know on my Taurus, there was some suspension noise and I later found out about a coil spring recall! A phone call won't hurt.
