On 6/27/26 at approximately 12:30pm, I was stopped at a red light for about 10-15 seconds at a major intersection. The vehicle was stopped on a slight incline. My feet were not on the pedals, the car was set with one pedal drive engaged at the "high" setting, cruise control/pilot assist was not active, my seatbelt was on, `Creep Forward was disabled, and the car had been completely stationary for those 10-15 seconds. Suddenly, the car spontaneously started to accelerate - not slowly rolling forward, but actively accelerating with significant forward propulsion. Given the configuration in which the vehicle was set, the vehicle shouldn’t have moved at all let alone with such sudden speed. Fortunately, there was no one in front of me and I was paying close attention so I was able to immediately step on the brake pedal to stop the car. The car only traveled about 2-3 feet, but that's only because I reacted so quickly. Without immediate braking the car would’ve entered into the intersection and cross-traffic.No warning lights or symbols appeared prior to the malfunction and the dealership could not determine the cause. The vehicle experienced another unexpected propulsion event with another driver the day after the Volvo service department inspected it. I requested that Volvo cars preserve any available diagnostic, event, telemetry, or other vehicle data potentially associated with either incident so that it is not overwritten or lost.The vehicle is available for inspection upon request
