I am submitting this complaint based on recurring drivetrain and structural failures in my 2020 BMW X7 (VIN: [XXX] ), which raise serious concerns about reliability and safety. Most recently, the vehicle exhibited shuddering, power loss, and a -??neutral-like-?? disengagement at low speeds. BMW of Pembroke Pines confirmed this through a test drive. However, instead of mechanical replacement, the dealer performed a VTG oil flush and attempted a calibration, which-?"according to their own documentation-?"-??lost connection.-?? These signs point to recurring issues with the ATC (transfer case), a known point of failure in several BMW X models. Additional manufacturer defects I-??ve experienced include: - Two incidents of cabin water intrusion from separate leaks - A dashboard panel burst shortly after purchase - Rear seat failure requiring a $7,000+ repair BMW North America refuses to provide further assistance despite acknowledging the repair history. This leaves me with a potentially unsafe vehicle, prone to recurring drivetrain failure without a clearly defined remedy. I respectfully request that NHTSA investigate whether the Active Transfer Case and related VTG components in the BMW X7 pose a defect trend requiring formal attention.

The failed component was observed when the Restraint warning icon appeared. There was no accident because the vehicle was taken to the BMW dealership for investigation. There is a warning not to drive because the Restraint system may not work properly. This is a safety issue with no work around to operate the vehicle in a safe manner. After reviewing multiple threads online, it appears that my situation is not uncommon with BMW. I took the vehicle to BMW service and they confirmed there is a fault in the harness that allows the airbag, seat belt and tensioner to not operate properly in the case of a collision. The service advisor admitted they have seen this before and knew how to repair it. The repair is too costly to investigate the harness where the defect in the wiring occurred, so the opt to replace the harness in a parallel manner, which still takes 7 hours and over $2200. The vehicle is only a few months out of warranty and has less than 18,000 total miles. They is no way that the harness experienced normal wear over the years to cause this with such low miles. They attempted to blame the Arizona heat as possible cause, but the vehicle was in Illinois to 2 of the 4 years and while in Arizona, it is parked in my air conditioned garage. Heat is not the cause. This situation is a design defect during assembly or a defective harness at manufacturer. BMW would not accept any responsibility for the issue, which is a safety liability to passengers.
