One problem related to rearview system braking has been reported for the 2020 Audi A6. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Audi A6 based on all problems reported for the 2020 A6.
The rear view camera on the vehicle stops working intermittently. I have provided photographs of this to the dealer. Their scanning of fault codes noted that the "right environmental camera faulty b127d04: rear environmental camera faulty. " the ticket also notes they found multiple sporadic faults for b127f04. Although they have admitted to finding faults with the camera, they refuse to fix this because they could not duplicate the exact behavior at the time it was in their shop. By definition, this is an intermittent issue. Audi had other model years recalled for this same issue. I believe this is a serious safety threat as one can't see things behind you and a person or vehicle could be hit. Audi is aware of this issue and is refusing to repair it under warranty.
