The 2023 Audi S4 is a compact luxury sport sedan that blends everyday comfort with serious performance, positioned as a quicker, sharper alternative to the A4. It’s ideal for drivers who want all-weather traction, a premium cabin, and strong acceleration without stepping up to a larger (and pricier) S6 or full-on RS model. The 2023 model continues the B9-generation S4 (updated styling and tech introduced for 2020), so it benefits from a mature platform with well-sorted handling and refinement. In the segment, it competes with the BMW M340i and Mercedes-AMG C 43, emphasizing a balanced, confidence-inspiring feel.

1) 3.0L turbocharged V6 power: The 2023 S4 uses a 3.0-liter turbo V6 with 349 horsepower and 369 lb-ft of torque, delivering quick passing power and strong midrange pull. 2) Standard quattro all-wheel drive: Audi’s quattro system is a major reason shoppers choose the S4, improving traction in rain and snow while helping the car put its power down cleanly. 3) 8-speed automatic transmission: A responsive 8-speed Tiptronic automatic comes standard, tuned for both smooth commuting and faster sport driving. 4) Sport-focused chassis and braking: The S4 includes performance-tuned suspension, strong brakes, and multiple drive modes to change steering weight, throttle response, and transmission behavior. 5) Modern tech and safety suite: 2023 models typically offer Audi’s Virtual Cockpit digital gauge cluster, available driver assistance features (like adaptive cruise control on properly equipped cars), and a premium interior with supportive sport seats.

Shoppers searching “2023 Audi S4 reliability” should know the S4 is generally solid for a high-performance luxury sedan, but it isn’t maintenance-free. The most common “2023 Audi S4 problems” tend to be technology glitches, wear items, and a few recurring Audi/VW turbo-engine themes. 1) Infotainment and connectivity glitches (often early ownership): Some owners report intermittent Bluetooth pairing issues, MMI screen freezing/rebooting, or CarPlay/Android Auto dropouts. These problems may show up within the first 5,000–15,000 miles and are often improved with software updates or module resets. 2) Thermostat/water pump coolant leaks (can appear 20,000–60,000 miles): While not every 2023 S4 will experience it, Audi turbo engines have a history of cooling system seepage at the thermostat housing or water pump area. Symptoms include coolant loss, sweet smell after driving, or a warning message. Catching leaks early helps prevent overheating and secondary damage. 3) Brake wear and brake dust (varies with driving style; often 15,000–30,000 miles): The S4’s performance brakes can wear faster than a standard A4, especially with spirited driving or heavy city traffic. Some owners also note high brake dust on the front wheels, which is more of an annoyance than a failure but commonly reported. 4) Suspension noises or alignment sensitivity (commonly 10,000–30,000 miles): A few owners note clunks or creaks over bumps, sometimes tied to bushings, end links, or simply wheel/tire setup and alignment. The S4’s sport-tuned suspension and low-profile tires can make it more sensitive to potholes and uneven road surfaces.
