What is causing the rattling noise in the front end of this car? on 2006 Buick Lucerne

Driving down the road if its a little rough, there is a rattling noise as if something is loose under the hood.
car only has 25,000 miles on it, so should still be in new shape. Been doing this the last 2000 miles or so.

If it's bump influenced and doesn't take place turning, you want to have the sway bar links looked at, the sway bar itself, and the rack mounts to the sub-frame...
thank you, will take it to the dealer
please provide me a follow up response/find to your problem, thanks AJ
