2020 BMW X3 M electrical system problems

“I am reporting a chronic manufacturing defect on my 2020 BMW X3 that poses an immediate electrical short-circuit and vehicle safety hazard. The passenger-side panoramic sunroof drainage system/roof structure leaks water heavily through the side panel joint of the door frame, directly saturating the front passenger floor carpet. This issue has been ongoing since I received the vehicle in 2020.The vehicle has been brought to Kelly BMW of Columbus, Ohio, at least four separate times since 2020 specifically to address this leak. Technicians have replaced outer seals and cleared tracks, but the leak persists, and on the last visit, unqualified dealership staff claimed they "could not find anything wrong. "This is a severe safety risk: BMW places the primary electronic fuse blocks and vital vehicle wiring harnesses directly underneath the front passenger floorboard carpet. Constant water logging in this exact area threatens to cause sudden, catastrophic electrical failures, component shorts, or vehicle stalling while driving. The manufacturer has failed to issue a recall for this known, widespread G01 platform defect, and dealership service centers lack the training…”

“I am submitting this complaint regarding ongoing and potentially dangerous mechanical failures involving my vehicle that have repeatedly occurred despite numerous repair attempts by the dealership. Over the past year, I have taken my vehicle to the dealership more than 10 times for serious recurring issues. The problems have included: Drivetrain malfunction warnings Engine warning lights Oil leaks Smoke coming from the vehicle The vehicle unexpectedly shifting into neutral while driving Sudden loss of drivability requiring the vehicle to be towed The dealership has repeatedly stated that the issues were repaired, and at one point even provided a one-year warranty on the repair work. Despite this, the same problems have continued to occur. Most recently, the drivetrain malfunction warning and engine light returned again, smoke came from the vehicle, and the car shifted into neutral on its own, becoming completely undriveable and requiring towing. I have spent more than $10,000 on repairs related to these ongoing issues, yet the vehicle remains unreliable and unsafe. My primary concern is the safety risk posed by the drivetrain failure and the vehicle…”
