I was pulling into a parking space at very low speed and was in the final stage of positioning the vehicle in the parking space. I was intentionally controlling the vehicle’s movement by gradually lifting my foot from the brake pedal. Instead of continuing to move forward slowly as expected, the vehicle suddenly accelerated forward with substantial force and speed greater than would be expected from simply releasing the brake pedal, and crashed into a cement wall. I did not intentionally press the accelerator or attempt to accelerate the vehicle. The collision caused substantial damage to the vehicle. The repair estimate is $14,644.25. The vehicle was NOT in cruise control. The Volvo-installed rubber floor mats were securely attached to the factory retaining pegs on the floor and were not loose or displaced. The vehicle’s Forward Collision Avoidance system did not engage or provide an automatic braking intervention before the vehicle struck the cement wall. The airbag did not deploy. The seat belt did not lock into place during the crash. I am submitting this complaint because the vehicle was being maneuvered at extremely low speed during a parking maneuver and unexpectedly accelerated forward with sufficient force to cause a collision with a cement wall, and resulted in significant vehicle damage. I am concerned that this may represent a safety defect. I request that NHTSA investigate whether this incident is part of a broader pattern involving the 2023 Volvo XC40 B5 mi
