2010 Honda Pilot 2010 Honda Pilot noise when accelerating

When accelerating between 25-45 mph I hear a noise that sounds like a metal piece spinning very rapidly. It is not extremely loud, just rather annoying when no radio on, etc. It does not happen at lower speeds, and cannot really be heard above 45 mph. Any idea what this could be? Will it lessen over time with the break in of the new vehicle?

Thank you.
