2017 BMW X5 MRecalls, problems, MPG & safety

“While driving, the electronic parking brake (EPB) system malfunctioned. The vehicle was stopped in DRIVE with Auto Hold active. When the driver door was opened briefly, the vehicle attempted to transition from Auto Hold to applying the electronic parking brake as a safety function. At that moment, the EPB malfunction warning appeared and the parking brake system faulted. There were no prior mechanical brake issues (no dragging brakes, no unusual noises, no brake wear symptoms). The issue appears to be an electronic/control-related failure of the EPB actuator/control unit rather than typical brake wear. A repair facility retrieved multiple diagnostic fault codes related to the electronic parking brake actuator/control unit and recommended replacement of the EPB actuator assembly followed by initialization/calibration and clearing of faults. This creates a potential safety risk because the electronic parking brake may apply unexpectedly or may not apply/release as intended during safety logic events (such as opening the driver door while stopped), potentially immobilizing the vehicle or creating a hazard in traffic or parking situations.”

“I am writing to formally document two significant incidents involving the complete failure of the high-pressure fuel system in my BMW vehicle, VIN [XXX] , which have raised concerns about the reliability of this component. On [XXX], while navigating city street traffic, my vehicle, with 57,376 miles, experienced a total loss of power, resulting in the vehicle stalling in the left lane. The vehicle was towed to an authorized BMW dealership, where the entire high-pressure fuel system was diagnosed and replaced under warranty. As the second owner of this vehicle, I acquired it from my neighbor, the original owner. Upon reviewing the complete service records provided by the previous owner, I discovered that a nearly identical issue occurred at 39,066 miles. The service documentation states, "Client reports that while driving, the vehicle lost power and stalled." At that time, the high-pressure fuel system was also fully replaced. Further investigation revealed that BMW issued a safety recall notice between these two incidents, acknowledging potential failures in the high-pressure fuel pumps. However, the recall indicated that no remedy was available at the time.…”
