Loud hum in 2015 Buick Enclave

I have a loud humming sound coming from the front end when driving. Any idea what it may be.

Does it change in frequency as you change speed? On a open road with no traffic, try shifting into neutral. Does that change the sound?

My guess is a wheel bearing, which is dangerous as the wheel could fall off. Get it checked out.

Is it under warrantee? if so, get it to a dealer. In any case, get it checked.
