My wife just said the car is buzzing/humming in the garage. I walked in and sure enough there was a buzz. With the echos I could not pin point it.

I pulled it out of the garage, closed the garage and buzz was gone.

Drove back in and shut off ignition. No buzz.

Ever heard of this?

Yes. Same question has been asked here a number of times. It's probably the fuel evaporation control system running a test. Seems to do this after the car is stopped for a few hours. I believe the 2013 is the first year with this particular test. If I recall correctly, someone posted that it might be mentioned in the 2013 owners manual.
