2025 BMW I4 EDRIVE40

On November 18, 2025, I was driving a 2025 BMW i4 eDrive, VIN [VIN], at approximately 10–15 mph in slow traffic. I applied the brake pedal firmly when the vehicle in front of me slowed, but the vehicle did not decelerate as expected. The vehicle continued moving forward, resulting in a rear-end collision with the car in front of me, which in turn struck another vehicle. Prior to this incident, the vehicle occasionally exhibited brief reductions in forward drive power that were subtle and initially attributed to drive mode (e.g., comfort/eco or battery status). At the time of the incident, the vehicle was subject to Safety Recall 25V-395, but I had not received any recall notification prior to reporting the incident to BMW. This appears to be a potential vehicle safety defect involving braking performance or interaction of propulsion and braking systems, as the vehicle did not stop when brake input was applied under normal conditions. I am reporting this to NHTSA for investigation of a possible safety defect. Related documents, including accident reports, repair invoices, and correspondence with BMW regarding ongoing investigation and requested diagnostics, are available upon request.
