Problem: Volkswagen Group of America, Inc. (Audi) is recalling certain 2021-2022 Q5 Sportback, SQ5 Sportback, 2018-2022 Q5, and SQ5 vehicles. A liquid spill in the rear seat, or water ingress from an insufficient body seam underneath the vehicle may allow liquid to penetrate the gateway control module, causing it to shutdown.
