    Hyundai Motor America (Hyundai) is recalling certain 2021-2022 Santa Fe, Santa Fe HEV, Elantra, Elantra HEV and 2022 Elantra N and Santa Fe PHEV vehicles. Due to a damaged printed circuit board, the rearview camera image may fail to display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

    Risk: A rearview image that does not display reduces the driver's visibility and increases the risk of a crash.
