I am reporting a serious safety failure in my 2024 BMW iX related to the Forward Collision Warning (FCW) and Automatic Emergency Braking (AEB) systems. Recently, my vehicle failed to detect a slowing car ahead, and the emergency braking system did not engage, resulting in a rear-end collision. This malfunction has caused financial loss due to repair costs and raises severe safety concerns, especially since my infant child was in the vehicle at the time. A functional AEB system should have prevented this accident. Given recent BMW recalls for braking system issues, I am deeply concerned that this failure is part of a broader defect. I urge NHTSA to investigate potential system defects in the 2024 BMW iX to prevent further accidents and protect lives. Please advise on the next steps for escalating this safety concern.
