What year, what trim level, does it happen when driving or standing still...
Record it with your phone, upload the video to you-tube and post a link to it here.

Neither has the dealer I have a feeling it has something to do with the heater core possibly leaking slowly and making a sound that you can’t physically hear an the noise cancellation is picking it up trying to cancel the sound
