Automatic Emergency Braking problems of the 2015 BMW X3

X3 started locking up the brakes, it seems that every time you pressed the breaks the calipers will engage and would not release them, making the vehicle completely stop or force you to accelerate to move the vehicle forward by force and get out of the moving traffic. No error codes came up at all or warning lights on the dashboard. The only way to resolve the issue was to turn the vehicle off and start again after a few minutes. The same issue occurs if you use the auto hold function, the vehicle will automatically engage the emergency breaks and you lose complete control of the vehicle, until the car is turned off to reset. The calipers were replaced and drained the brake fluids as a measure since no error codes were detected. Problem persisted and it got worse, making it very unsafe to continue to drive the vehicle. Fields BMW in winter park florida, confirmed the problem as the dsc hydro unit failure, although no error codes or warnings still and shared that they had several BMW's come in with the same issue and no error codes detected. 4k for the part only and in back order in germany for 2 months. I contacted BMW corporate to discuss the problem. It seems BMW corporate is aware of the issues with the hydro unit in some models, but not on my model, it seems to me that this is not only a major BMW design failure but a safety problem with the vehicle I believe needs to be addressed by the company.
