My 2016 is doing this too. It only happens when turning in reverse... It is odd. I've worked on cars for 10 years (6 years professionally) and I've never heard a noise like this. I wish I still had access to a chassis ear to help figure this one out.
With a few exceptions, my approach with difficult-to-find suspension noises has been: let the problem get worse until you can find it. Some exceptions are: check power steering fluid; check the brakes and studs; check the cotter keys on the hubs; check for grease fling from CV joints (might as well repack and throw-on a split boot... either that postpones failure a year or two, or it doesn't).
If it's a bearing or ball-joint and it's already making noise, then once you've spent days locating the problem, you'd have to pay the same amount to fix it, as you will once the cause of the noise is obvious.
I think mine was the hub. At least, my wife drove into a curb, the car was making a high pitched whining noise. Took it in. Left front hub was terrible; wouldn't even turn by hand. Replaced (about 500 bucks). Noise is now gone when turning the wheel.
