BMW of North America is recalling 28 model year 2020-2021 530i xDrives, 540i xDrives and model year 2021 740Li xDrives.
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.
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.
What to do
BMW will notify owners, and dealers will replace the output shaft(s) free of charge.
The recall is expected to begin March 29, 2021.
Owners may contact BMW customer service at (800) 525-7417.
