Loose buttons?

Seemed to be a common problem with the regular Nexus 5.

Opened my 5X and noticed the power button and volume rockers are loose.

I guess this is a common problem with the 5X as well?

Loose piece inside the phone? Makes a rattle sound when shaking.

I got my N5x yesterday and I read online that some users are experiencing a loose piece of hardware inside the phone. I held the power/volume rockers down and shook again, it appears the loose piece is inside of the camera, or near it. When I opened my N5x, I tested this and mine's affected. I have a 32GB Carbon 5x. Anyone else affected by this? Do you think it should warrant an exchange?
