2018 AUDI S4 Recalls — Canada & USA

The 2018 Audi S4 has 2 recalls, both involving the front passenger airbag, which can be disabled by a fault in the passenger seat detection system and fail to deploy in a crash.

Corrosion on the wiring connected to the passenger seat sensor can cause the system's software to misread the fault and shut off the passenger airbag entirely. A separate issue with the sensor itself can produce the same result. In either case, a front passenger would have no airbag protection in a collision.
