    BMW of North America, LLC (BMW) is recalling certain 2020-2021 X3 sDrive 30i, X3 xDrive 30i, X3M 40i, X3 xDrive 30e, X4 xDrive 30i, X4M 40i, 530i, 540i, 540i xDrive, M550i xDrive, M5, 550e, 550e xDrive, and 550e iPerformance vehicles. A small portion of the rearview image may be slightly obscured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

    Risk: If the driver relies on only the rearview camera image, the reduced rearview image view can increase the risk of a crash or injury.

    Remedy: BMW will notify owners, and dealers will inspect and, if necessary, program the rearview camera with updated software. The recall began November 18, 2020. Owners may contact BMW customer service at 1-800-525-7417.
