Incident Description: On April 4, 2025, after placing the vehicle in "Park," it suddenly and rapidly began reversing without driver input. The open door struck me, knocking me to the ground and the vehicle rolled over my legs, groin and arm before stopping after colliding with a dirt pile. This resulted in severe injuries and hospitalization. The vehicleâs gear selector is the rotary dial type. Post incident diagnostic reports showed communication faults between the shifter assembly and transmission control. Jaguar Land Rover North America (JLRNA) currently has the vehicle under extended diagnostic evaluation but has not provided a confirmed root cause. The malfunction may relate to electronic gear-shift or transmission control failures. I am reporting this incident for federal safety review, as this defect presents a potential risk of uncommanded vehicle movement and serious bodily harm. Additional Information: The vehicle remains in JLRNA custody. Original diagnostic codes were recorded by their engineer. I have experienced significant injury and loss of use. I request NHTSAâs review and tracking of this defect for other potential affected vehicles.
