My 2014 Honda CRV makes a strange noise after starting?

It happens about 30 seconds after starting the car and sounds like a buzzing/vibrating sound coming from the dash. Any idea what this could be? Does not sound to be coming from the engine compartment so I think it is something electronic happening in the dash and it only happens after we start the car. It typically only happens once. Any ideas? Thanks
Added (1). And the noise only lasts 2-3 seconds then goes away and doesn't happen again until I turn the car on again.
