I noticed a noise when I drive up hill with this car.

It sounds like a rattle and I also hear like a rumble loud noise like the tire is hitting that plastic tire well cover but it is not that.

It happens going up hill all the time but, it also happened when I press the brake and I am at a stop then when I take off I will hear it for a couple of seconds. Then it will go away.

I did that test where you hold the brake all the way down put it in drive and hold rev it and when I reached about 1,500 rpm's it will make that noise constantly. It does not do nothing in reverse just drive.

Anyone know anything about these vehicles that would do that?

Good afternoon.

There is a shield on the catalytic converters that prevents items for hitting them and catching fire.

Check the shield and see if it is loose. Very common failure. Use a rubber mallet and tap it and see if you can hear the noise.
