The constant-velocity joint which transfers power between the transfer case and the rear drive shaft, may become damaged, possibly resulting in loss of power to the rear wheels.
A loss of power to the rear wheels can affect vehicle control, increasing the risk of a crash.
Additionally, when the vehicle is parked after a loss of power to the rear wheels and the parking brake is not engaged, unintended rollaway can occur, increasing the risk of a crash or injury.
What to do
BMW will notify owners, and dealers will replace the constant-velocity joint and inspect the transfer case, replacing it -- if necessary -- free of charge.
The recall is expected to begin May 18, 2020.
Owners may contact BMW customer service at (800) 525-7417.
