Is the 2019 Audi S4 reliable?

The overview describes reliability as decent for these years, while also noting that Audis typically require more maintenance than rival brands and that the S4 is below average for reliability. For used buyers, that means the car can make sense if you stay on top of upkeep, but long-term ownership risk is higher than you might expect from some mainstream alternatives.

What should I look for when buying a used 2019 Audi S4?

At 73.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was cosmetic or structural. Put inspection priority on body condition, panel alignment, and signs of inconsistent repairs, then make sure the car drives cleanly and feels tight over bumps and during hard acceleration. Because this model is a performance sedan with premium features, you should also focus on overall condition and maintenance quality rather than just mileage alone.
