Brakes (hydraulic), Brakes (hydraulic) Vehicle recall #21V062000 · 2021 · 893 vehicles
What's wrong: The rotor and shaft within the integrated brake system May not have been welded properly and could separate during a hard braking event, possibly resulting in a loss of the antilock brake system (ABS) and braking assistance.
Why it matters: A loss of ABS and a reduction in braking assistance can increase the risk of a crash.
The fix: Bmw will notify owners, and dealers will replace the integrated brake system, free of charge. Owner notification letters were mailed on May 25, 2021.
Backup camera, Backup camera Vehicle recall #21V096000 · 2021 · 13,858 vehicles
What's wrong: 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."
Why it matters: 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.
The 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.
