My son would be in the car and while I am saying it sounds like it's coming from his footwell he is telling me it's coming from my footwell. Eventually I narrowed it down to the EPS unit which is mounted to the steering column right behind the dash. The EPS seems to only make sounds at parking lot speeds and over very small but sharp bumps like road reflectors.
This morning on the way to work I wanted to find a nice long stretch of reflectors and cut the ignition while going over them to see if the sound stops when the EPS loses power but with traffic and all I didn't get a good chance. If this method works it would be a good way to prove if EPS is the source.
I have a 2013 with 97K on it. When I got the car it had 83k and didn't make this noise. It started after my first autox and suspect it was due to the high loads put on the EPS when autoxing. My car is completely stock suspension wise.
Here are some videos from the EPS thread which give good examples of how it sounds:
And this one when hard braking:

Wow, this noise sounds almost identical to mine. However, I do not think this is my issue.
I am fairly confident my noise is coming from the rear. On my way to lunch I pulled my EPS fuse. It was a beast to turn but my noise was still present.
