2023 S4 Sedan Reliability

Thus far, the 2023 Audi S4 has not been subjected to recalls. However, last year's model suffered one for an inoperative rearview camera display. The 2021 lineup was also recalled for potentially malfunctioning seat belt retractors and lock nuts on the rear axle assembly that may fail.

Should something uncharacteristically go wrong, the S4 gets coverage in the form of a limited and powertrain warranty that protects you for four years or 50,000 miles, whichever comes first.
