Was backing in a tight circle, very loud bang/thud from under the front end. I checked everything and couldn't find any broke parts. Still drove fine, but steering wheel was turned slightly to the right.

Took it to the dealer, tech finally found that the steering rack had jumped a gear and was starting to leak out both ends. New steering rack ($720 part) and she drives better than ever.

Had complained about a slight pull to the right since it was new. Now wheel is centered and she goes straight down the road.
