When shifting into Reverse, a small portion of the rearview image may be obscured, or the screen may not illuminate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Risk: If the driver relies on only the rearview camera image, the missing or reduced rearview image view can increase the risk of a crash or injury.
Fix: BMW will notify owners, and dealers will inspect the rearview camera software and update it if necessary, free of charge. The recall began April 16, 2021. Owners may contact BMW customer service at 1-800-525-7417.
Power train:driveline:driveshaft
Problem: BMW of North America, LLC (BMW) is recalling certain 2020-2021 530i xDrive, 540i xDrive and 2021 740Li xDrive vehicles. The output shafts (left/right) which transfer power from the driveshaft to the rear wheels may break due to a heat treatment error during supplier production.
Risk: A broken output shaft can lead to a loss of drive power or a rollaway condition in a parked vehicle (if the parking brake is not engaged), increasing the risk of a crash.
Fix: BMW will notify owners, and dealers will replace the output shaft(s), free of charge. The recall began March 24, 2021. Owners may contact BMW customer service at 1-800-525-7417.

The connection between the 48-Volt battery and the starter-generator may not have been assembled properly, which can cause increased electrical resistance at the connections.
Risk: Increased electrical resistance can increase the risk of a fire.
Fix: BMW will notify owners, and dealers will inspect the connection between the 48-Volt battery and the starter-generator assembly, replacing it if necessary, free of charge. The recall is expected to begin April 12, 2021. Owners may contact BMW customer service at 1-800-525-7417.
