G80/82 Brake Recall?

I seen this posted for multiple vehicles that included the 2021 M3/M4. This maybe why there are no driver reviews.

Date February 10, 2021

Component SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:MASTER CYLINDER | SERVICE BRAKES, HYDRAULIC:POWER ASSIST:HYDRAULIC

Summary BMW of North America, LLC (BMW) is recalling certain 2020-2021 8 Series Coupe, Grand Coupe and convertible 840i, 840i xDrive, M850i xDrive, M8 and 740 Li, 740 Li xDrive, 750 Li xDrive, M760 Li xDrive, X6 sDrive40i, X6 xDrive40i, X6 xdrive50i, X6 M50i, X6M, and 2019-2021 X5 sDrive40i, X5 xDrive40i, X5 xDrive50i, X5 M50i, X5M, X7 xDrive40i, X7 xDrive50i, X7 M50i, and [COLOR="DarkRed"]2021 M3, M3 Competition, M4 Coupe, M4 Competition Coupe, [/COLOR]X5 xDrive45e, 745 Le xDrive.

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.
Consequence A loss of ABS and a reduction in braking assistance can increase the risk of a crash.

Remedy BMW will notify owners, and dealers will replace the integrated brake system, free of charge. The recall is expected to begin April 5, 2021. Owners may contact BMW customer service at 1-800-525-7417.

Seems to be a different issue.

On certain vehicles, an internal part in the integrated brake system could fail during hard braking. If
this happens, there would be a reduction in brake boost and the antilock brake system (ABS) would
turn off. This can cause an increase in brake pedal effort that is required to stop the vehicle. A
sudden increase in brake pedal force and a loss of ABS braking could lead to an increase in
stopping distance. This could increase the risk of a crash.

The hydraulic unit needs to be replaced.
