NHTSA Complaint #11714291 — 2025 BMW X7

While driving under normal conditions, the Lane Keep Assist system on my 2025 BMW Alpina XB7 unexpectedly and violently jerked the steering wheel without driver input. The sudden steering intervention caused the vehicle to abruptly change direction and strike a curb, resulting in a loss-of-control event. This occurred without warning and could have resulted in a serious crash involving other vehicles, pedestrians, or roadside obstacles. Additionally, the adaptive cruise control system has repeatedly applied sudden and aggressive braking without an apparent reason or obstacle present. These abrupt braking events create a significant risk of a rear-end collision, as following vehicles are not anticipating such sudden deceleration. These issues involve advanced driver-assistance safety systems that are intended to enhance control and safety. Instead, they are operating in a manner that overrides driver input and introduces unsafe driving conditions. The servicing dealership acknowledged the issues and advised me not to use the Lane Keep Assist and cruise control features. Being instructed to disable safety systems due to unsafe behavior is unacceptable and does not resolve the underlying defect. Given the loss-of-control incident and the ongoing unpredictable braking behavior, I believe these defects present a serious safety risk to vehicle occupants and the public.
