    Back over prevention: sensing system: camera

    Volkswagen Group of America, Inc. (Audi) is recalling certain 2019-2026 vehicles. Please see the recall report for a complete list of models.

    Risk: A rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash.

    Remedy: Dealers will update the software, free of charge. Owner notification letters were mailed January 14, 2026. Owners may contact Audi customer service at 1-800-253-2834.
