2013 Hyundai Sonata GLS whistling sound from AC vent

Anyone get whistling sound from AC vent?
I get it when I drive 70+ MPH.
I started noticing this now that I am using AC more often (bought 2013 sonata in winter)
Should I just take it to dealer?
I am afraid I will not be able to show the tech unless I drive it at 70+ MPH and even then I may not get whistling sound.

You could check the cabin filter and see if it is dirty/blocked. Does it whistle on MaxAC with the blower/fan speed at all speeds, or only when the blower is at the highest setting? Mine whistles when the blower is at full blast, but not at speeds 1, 2, or 3.

But no on all days and the speed has to be above 70mph.
