strange noise when turning steering wheel
 

Hi all,

I've noticed a strange noise lately when I get in the car and turn the steering wheel. Below is a link to a video I shot where I turned the wheel lock to lock. This noise is generally only noticeable when I first get into the car and it is still parked. Not really noticeable when I'm actually in motion. Also, seems to be more pronounced on colder mornings.

Any ideas what it might be? I posted on Reddit and someone said to check the power steering fluid. But, when I do a search for that on the web I get hits that say this model vehicle uses EPS, so there isn't any fluid to leak out.
