NHTSA Complaint #11631507 — 2022 AUDI Q5

I started the car and , put it in reverse and the rear back up camera never turned on as required when backing up today. Rear camera didnt activate but the parking light on the audi was red as usual indicating it was activated. However the screen just went to its default app page (settings, carplay, etc.) I was unable to see pedestrians as I backed out of the grocery shopping center parking spot. Yes. Audi dealership keeps telling me there is no update and that my software version 3606 is the latest software( I have told the dealer, I have a black screen without apps, only LTE and clock show up occasionally) they have done a factory reset and so have i without resolution. No warning lights came on, it just said welcome (user name) and went to the regular media screen. I have a 2mb 7 second video of the incident I took with my iphone if needed
