2020 Audi S5

The 2020 Audi S5 sits at the apex of a three-year reliability valley, logging 25 complaints—second only to the 2018 model’s 26 and a sharp rebound from 2019’s six—alongside four recalls and 943 TSBs, a volume second only to the 2021 model’s 965. While 2021 saw owner complaints plummet to a single entry despite recalls climbing to five, the 2020 model remains the complaint peak for this generation, with electrical system and unspecified categories each generating six grievances though the data specifies no root cause. This positions the 2020 model at the tail end of a volatile 2018-2020 arc that contrasts sharply with the relative stability of 2015-2017 and the cleaner post-2021 record. With zero crash or fire complaints recorded, the concerns appear confined to non-catastrophic failures, yet the volume suggests persistent irritants. Given this concentrated documentation of problems and the demonstrably more reliable 2021 successor, buyers should either bypass the 2020 model or verify exhaustive completion of all four recalls and relevant technical service bulletins before purchase.
