I am writing to report a serious safety issue introduced by a recent firmware update regarding the Sport mode and 1-pedal driving behavior. After driving the vehicle in Sport mode, parking, and restarting, the dashboard prompts me to return to Sport mode. When I select "Yes," the dashboard indicates that the vehicle has switched to Sport mode. However, the vehicle silently reverts to Normal mode, which has a much more relaxed braking pattern for 1-pedal driving than the expected, shorter braking path of Sport mode. Compounding the danger, this issue occurs inconsistently. Sport mode occasionally does stick upon restart, which creates a false and dangerous level of confidence in the system. The unexpected drop in braking responsiveness has already caused multiple near-miss collisions.

On August 19, 2026, I was involved in a collision in my 2025 Ford F-150 Lightning after a suspected malfunction involving the automatic emergency braking, adaptive cruise control, and/or acceleration controls. Cruise control was on; BlueCruise was not. While on an exit ramp, I heard a loud warning beep, experienced automatic braking, and then felt the truck suddenly accelerate into the vehicle ahead. The unexpected braking and acceleration compromised my ability to control the truck and avoid a collision, putting me and occupants of the other vehicle at risk. I am concerned about driving this vehicle again, including with my daughter. Before the collision, I experienced three incidents in which the automatic brakes activated when no vehicles were around. I also reported a warning/error during a December 2025 service visit. The service record documents that visit; I do not know whether that issue is related to the collision. The loud warning beep occurred immediately before the collision. The truck has been at a Ford dealership for evaluation and is available for inspection upon request. The dealership has not confirmed or reproduced the suspected malfunction. The service manager told me its diagnostic testing would not necessarily show what happened during the incident and indicated limitations in obtaining crash-related data. I am requesting further investigation into the braking, cruise control, and acceleration systems. Ford Corporate and State Farm have been notified. I cannot confirm whether Ford Corporate, police, or insurance representatives have performed a technical inspection of these systems or retrieved event data. The cause remains unconfirmed.
