I also have got 2014 and I must say that on my vehicle this buzz took place not only when the ICE started to operate, but also on bumpy road. In attempt to do something about it, I broke the center console piece plastic. And the sound became even more annoying. So I went ahead and got a brand-new console piece(https://www.carid.com/center-consoles/), and put thin foamy vibration-reducing foam strip (adhesive). And I must say, this is probably the only thing in the car I do not regret breaking!
