The 2020 Audi S8 has 4 recalls, the most serious being two separate issues that can cause loss of vehicle control: an engine that may stall without warning and a rear axle that can fall out of alignment.
Moisture can enter the engine control module through a missing sealing pin in the connector, causing the module to malfunction and the engine to cut out while driving. On the suspension side, a rear axle lock nut can break and allow the rear axle geometry to shift, pulling the car off its intended path. This same rear axle misalignment also contributes to a separate tire concern: when the rear wheels are not properly aligned, tires wear unevenly or prematurely, which can reduce grip and raise the risk of a loss of control over time. There is also a camera-related recall: a software error can prevent the rearview camera image from appearing when the car is in reverse, leaving the driver without the rear visibility display they would normally rely on when backing up.
