Now the tough question: how to fix it?
That other members car is a 2016 with competition pack and 5 bolt top mounts!!!! I also work in the industry as Racer20, after reviewing the video and discussion I'm very convinced its not the steering rack causing the noise.
Oops, I thought yours was a 2017. Thanks for the help Mitch!

The dealer's "area rep" was out today and is looking into the steering gear issue. I don't have faith that this can be solved at the dealer level beyond just replacing random parts and claiming it's fixed, but we'll see wheat they say.
