What Problems Does the 2020 Audi S6 Have?

While the 2020 Audi S6 is generally considered reliable, some owners have reported issues. These include glitches with the infotainment system, such as occasional freezes or slow response times. Some have noted minor electrical issues, such as sensor malfunctions or issues with the ambient lighting.

There have been some recalls related to potential fuel leaks or airbag malfunctions, so checking the vehicle's VIN with the NHTSA (National Highway Traffic Safety Administration) is essential to ensure all recalls have been addressed.

Long-term reliability concerns typically revolve around the complexity of the engine and electronics. The twin-turbo V6, while powerful, can be prone to issues like oil leaks or turbocharger problems over time, especially if maintenance is neglected. The air suspension, while providing a comfortable ride, can also be a potential source of expensive repairs as the vehicle ages.

Some reports indicate that early production models might have experienced more frequent issues compared to later ones, so checking the production date can be beneficial. Overall, while the 2020 S6 offers a blend of performance and luxury, potential buyers should be aware of these possible issues and ensure a thorough pre-purchase inspection.
