I took delivery of a new 2021 Q3 on 8/3/2021. Last week with about 200 miles on the OD, I was backing out of a driveway onto a perpendicular street. When turning the wheel I heard a loud "Crunch like sound" as if I had hit or rolled over something. I pulled forward and adjusted the steering wheel and backed up again. There was nothing visible in the rear view caner. Same loud noise as I turned the wheel to back into the road. (apox. 90degrees) Third time was a winner. No noise. The driveway and road are flat. There are nor curbs. Driveway and road are paved. Nothing visible showed up in the rear view camera. I only now have less than 400 miles on the vehicle and have not replicated the noise. Any thoughts??
