What Problems Does the 2021 Audi S5 Have?
While the 2021 Audi S5 generally enjoys good reliability ratings, some frequently reported problems involve the infotainment system. Users have occasionally reported glitches, slow response times, and connectivity issues with Apple CarPlay and Android Auto. Some owners have also noted minor electrical issues, such as sensor malfunctions or issues with the driver assistance systems.
Specific to the 2021 model year, it's crucial to check for any outstanding recalls related to fuel system components or airbag deployment. Information on recalls can be found through the National Highway Traffic Safety Administration (NHTSA) website.
Long-term reliability concerns often revolve around the complexity of the modern turbocharged engine and the sophisticated electronic systems. The turbocharger itself can become a point of concern as mileage increases. Proper maintenance, including regular oil changes with the correct synthetic oil and adherence to Audi's recommended service schedule, is critical to mitigating potential issues. The direct injection system can also lead to carbon buildup on the intake valves, which may require periodic cleaning. It's advisable to obtain a thorough pre-purchase inspection by a qualified mechanic familiar with Audi vehicles to identify any existing or potential problems.

How long will the 2021 Audi S5 last?
With proper maintenance, a 2021 Audi S5 can reasonably be expected to last for 150,000 to 200,000 miles or 10-15 years. Factors significantly impacting longevity include adherence to the manufacturer's recommended maintenance schedule, driving habits, and climate conditions. Long-term durability can be affected by potential turbocharger wear, carbon buildup in the engine, and the reliability of electronic components. Regular fluid changes (oil, transmission, coolant) are critical. Suspension components might require replacement around the 100,000-mile mark. The long-term reliability of the infotainment system is also something to monitor.
What Technology & Safety Features are Included?
The 2021 Audi S5 features a strong suite of built-in tech. The standard infotainment system includes a 10.1-inch touchscreen display with Audi's MMI interface, Apple CarPlay, and Android Auto.

How Does the 2021 Audi S5 Compare to Other Sedan?
The 2021 Audi S5 competes with vehicles like the BMW 4 Series/M440i, Mercedes-Benz C-Class/AMG C43, and Infiniti Q60 Red Sport. The S5 offers a good balance of performance and luxury, with its Quattro all-wheel drive providing excellent grip. The BMW 4 Series (especially the M440i) often boasts sharper handling and slightly better driver engagement. The Mercedes-Benz C-Class offers a more opulent interior but might not be as sporty. The Infiniti Q60 Red Sport delivers strong performance but lacks the refinement of the German rivals.
In terms of reliability, the Audi S5 is generally comparable to its German counterparts, although some reports suggest the BMW might have a slight edge. Price-wise, the S5 is competitive within its class.
Alternatives to consider: If ultimate performance is a priority, the BMW M4 is a step up. If luxury is paramount, the Mercedes-Benz C-Class might be a better fit. The Lexus RC F offers similar performance with potentially better long-term reliability but lacks the modern tech of the S5. Overall, the Audi S5 remains a strong contender, particularly for buyers seeking a balanced blend of performance, luxury, and all-weather capability.
