Although the S4 has only been partially rated (full marks in rollover tests), the A4 sedan on which it is based has been comprehensively evaluated. Safety reviews for the Audi A4 are excellent, with only front crash tests yielding anything less than perfect from the NHTSA. The IIHS concurs with a full complement of top scores - the A4 was also awarded Top Safety Pick+ for 2022.
NHTSA safety ratings are not available at this time.
Standard equipment includes LED headlights with auto high beams, rain-sensing wipers, a rearview camera, lane departure warning, and forward collision detection with autonomous emergency braking. Six airbags for frontal, side-impact, and curtain protection are also included. Rear side-impact airbags are optional, as are features like Audi side assist with rear pre sense and parking sensors, but only on the base car as part of the Convenience package. Previously optional and now unavailable on Premium and standard on some of the higher trims are features such as head-up display, park assist, blind-spot monitoring with rear cross-traffic alert, and vehicle exit warning, adaptive cruise control with traffic jam assist, and traffic sign recognition.

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.
