    Back over prevention: sensing system: camera

    Kia America, Inc. (Kia) is recalling certain 2020-2022 Niro EV vehicles. The circuit board for the rearview camera may become damaged and cause the rearview camera image not to display.

    Remedy: Dealers will replace the rearview camera, free of charge. Owner notification letters were mailed November 7, 2025. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall is SC342.
