Fatal crashes in the US
From 2020 to 2023, 28 S4 vehicles were involved in crashes on US public roads in which someone died, and 19 people died inside them. These are counts, not crash rates: a model with more cars on the road shows up more often, and people killed outside the vehicle are not counted here.

These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
