Very soft, random beeping that comes from drivers console in my 2014 Tahoe

[John Hardison]

I have a very soft beeping that comes from somewhere around the steering wheel of my 2014 Tahoe. At first, I thought it was part of the music I was listening to, but I turned the radio off and it continues. It is very soft, somewhere between a buzz and a beep. It is not a chime. It is totally random, sometimes going as often as once every 5 seconds, sometimes minutes will pass before hearing it again. I just bought the vehicle used, so I don't know if it always did it or just started. It is driving me a little crazy. Any ideas?
