The 2020 Audi A5 has 4 recalls, the most serious involving a rear axle lock nut that can break and misalign the rear axle, causing the driver to lose control of the vehicle.
A related recall addresses the same rear axle misalignment issue from a different angle: when the axle goes out of alignment, tires can wear unevenly or prematurely, raising the risk of a crash before the driver notices anything is wrong. On the safety equipment side, the front passenger airbag sensor can fail to properly detect an adult occupant in the seat, which may cause the airbag to suppress itself when it should deploy, leaving the passenger without full protection in a crash. There is also a wiring concern specific to Sportback body styles: the wiring harness running near the spare wheel well may lack protective covering where it could chafe, and if the rear of the vehicle takes an impact, the damaged wires can disable the hazard lights and prevent the doors from being opened from outside, complicating any post-crash response.
