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. Risk A gateway control module shutdown will suddenly reduce engine power, increasing the risk of a crash. Fix Dealers will install a protective cover on the gateway control module and seal an underbody seam as necessary, free of charge. Owner notification letters were mailed January 21, 2022. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 90S9.

Two numbers, one recall

Every safety recall carries two identifiers. 90S9 is the number Audi assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 21V947000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.
