Other Fuel System Pump problems of the 2012 BMW 135

Vehicle stalls when more than 1/8 throttle is applied, vehicle has difficulty starting. Check engine light comes on when applying small throttle inputs. The 4 previous years of this vehicle make and model, the high pressure fuel pump has had a known problem which resulted in a class action lawsuit that adjusted the warranty period for the four previous model years up to 120k miles. BMW made slight changes to the engine for the next model years, but left the exact same part that resulted in the original lawsuit settlement. That part is the point that failed on my vehicle. Should the warranty extension they agreed to in the settlement apply to all makes and models BMW made with the same defective part? this problem caused my wife to be stranded in the middle of the freeway and had to be towed out of the lanes of traffic.
