When vehicle was in Reverse parked in garage with garage door open, I removed my seatbelt and opened the door to exit vehicle believing it was actually in Park. The vehicle rolled backwards at idle speed as I tried to get back in to apply the foot brake. The open drivers door collided with the garage wall and stopped the vehicle before I could stop it with the brakes. A body shop manager doing an in home estimate told me that a 2024 F 350 has an Automatic Return to Park shift feature that should have immediately moved the column mounted shift to Park and applied the emergency brake. This feature was apparently installed in all Super Duty trucks in 2023 when the electric column shifter was added. It did neither of these things and collided with the wall damaging the wall and drivers door. I believe this is a defect in a safety critical system and filed a complaint with the Ford Customer Service Concerns department. They told me they would escalate to their general counsel but if I filed an insurance claim, that the complaint would no longer be active. No lawyer I contacted would take my case because a significant personal injury did not occur. I was advised to file insurance claim for both home and property policies.
