Noise when steering

I have a 2013 DCSB v6 and have noticed an intermittent high pitch whine coming from the firewall area whenever I corner relatively hard, or hit a bump while cornering. The noise typically stops a few seconds after the turn/bump and I don't notice any difference in the handling when it occurs.

Anybody know what this is? Is it something I should be concerned about?

 

Wheel bearings? Does it happen when you corner left? Right? Both? Do you get the noise if you turn full lock while parked?

 

I've primarily noticed it when turning left, but its happened when turning right as well. It only happens when I'm cornering at speed (30-40mph) under decent g-forces. It almost sounds like a small electric motor/pump running.
