While executing a manual parking maneuver (< 5 mph) in "B Mode" (one-pedal regenerative driving mode, where easing off the accelerator initiates vehicle deceleration), the instrument cluster displayed a "Parking assistance malfunction" warning message. Simultaneously, without driver accelerator pedal input, the electric drive unit initiated an uncommanded full-torque power surge. The vehicle surged forward uncontrollably, mounted and jumped over two concrete parking barriers, collided with two stationary parked vehicles, and pushed both vehicles approximately 4 feet from their original position before coming to a stop. This created an extreme, life-threatening situation in an active parking area where pedestrians and drivers were exiting nearby vehicles. The physical energy required to clear two concrete barriers and displace two 4,000+ lb stationary vehicles demonstrates continuous, uncommanded high-torque motor output rather than a foot slip. Because "B Mode" operates by lifting off the accelerator pedal to slow down, no pedal-swapping or braking confusion was occurring at the time of the event. Current Status: Vehicle is at Braman BMW under a strict hold for Event Data Recorder (EDR) and Electronic Control Unit (ECU) diagnostic extraction to preserve freeze-frame fault data and active diagnostic trouble codes associated with the "Parking assistance malfunction" warning. Executive case opened with BMW North America and insurer (USAA) for product liability subrogation.
