NHTSA Complaint #11630748 — 2015 BMW R1200 GS

It is not clear which brake component is failing. It seems to be either the master cylinder or the ABS control module, but nothing seems to be conclusive. The failure alters the power of and force required to apply the rear brakes, changing the riding characteristics of the motorcycle that could lead to serious injury or miscalculations in application of both front a rear brakes to minimize stopping distance. Apparently the component has been inspected by the manufacturer, however there has been no concrete solution that would guarantee a permanent solution. There are no warning lamps or visual indicators to prepare riders that the rear brakes may be compromised or dysfunctional. There have been multiple incidents of this failure from new.
