While driving at approximately 25 mph on a local street in Seattle, WA, my Tesla suddenly engaged the brakes without any apparent reason. The vehicle was not in Autopilot or Full Self-Driving mode, and my foot was actively pressing the accelerator pedal at the time. The braking was abrupt and forceful, causing a sudden deceleration. The weather was clear with good lighting. There were no obstacles, vehicles, or road hazards in my path that could have triggered the braking. The unexpected stop was shocking and could have led to a rear-end collision, as there were vehicles behind me.
