2019 Audi Q5 Exterior Lighting

The right back up light is defective. This light is in the right rear light housing that sits in the rear bumper. The defective light indicator came on before the 5 year/40k mile warranty had expired. The lamp bulb was changed as I believed this was the cause of the defect error. Took vehicle to Audi dealership where the car was purchased and the service advisor mentioned this happens "all the time" and the entire rear light housing will need to be replaced. Technician diagnostics confirmed this. The bulb was not in-fact out, the power/wiring to the housing was not malfunctioning and the error/fault/malfunction is in the rear bumper light housing. This same issue with 2018 and 2019 Audi's was reported in a thread on [XXX] as well. I feel this is a manufacturing defect and repair/replacement should be covered by the manufacturer, not the consumer. Not having an illuminated reverse backup light is a safety concern for all drivers. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving on the highway in the early morning hours and several warnings appeared stating that the left and right tail lights, left and right brake lights, and center brake lights where faulty. It was dark outside and raining, and I immediately had no rear lights of any kind driving on the highway. The dealership was able to correct the issue with a technical service bulletin, but given the extreme danger involved in not having any working rear lights, I would expect this to be a recall and done free of charge, regardless of warranty status. Because my vehicle was 10K miles beyond the warranty, I had to pay a flat diagnostic fee which simply doesn't make sense. If there is service bulletin, why isn't this update made proactively?
