Earlier this year I was notified by BMW that as of Feb 2022 my car would lose all networking capability due to the phase out of 3g cell towers. The "connecteddrive" package would become inoperative, and importantly, would no longer be able to route my travel according to traffic. My heads-up display is currently very well integrated with the navigation system, adaptive cruise control, and safety warning systems. I consider these important safety features. BMW has offered no fix for this. I have suggested to them that simply permitting the driver to tether the navigation (by usb or bluetooth) to a cell phone would solve the problem, but they have refused. The nav system and the BMW cell phone app both prevent tethering, which otherwise is built into the BMW's windows ce-based operating environment. I don't want to navigate using my phone, as it would be a 3rd display (the one in the dash, the hud, and the phone). I think one driver with 3 screens would be a safety hazard. Can you help get them to permit tethering to my cell phone once the 3g towers are gone?.
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.
