The 2020 Audi S6 has 6 recalls, the most serious being two that can cause sudden loss of control: a broken rear axle lock nut that can misalign the rear wheels, and liquid spilled in the rear seat penetrating a control module and cutting engine power without warning.
The passenger airbag presents a separate safety concern: the deployment panel may not be scored correctly, meaning the bag could fail to open properly in a crash or send plastic fragments into the cabin. On the instrumentation side, the fuel level sender can stick and display an inaccurate reading, potentially causing the engine to stall when the tank runs dry without warning. There is also a rear axle alignment issue that, while less acute than the lock nut defect, can cause uneven or accelerated tire wear that degrades handling over time. Rounding out the list, a software error can prevent the rearview camera image from appearing when reversing, reducing visibility behind the vehicle.
