Owners/service Manual problems of the 2017 Ford Expedition

Automatic running boards came down when door open, as usual. They then went right back up and pinned my dogs front paws, legs between running board and car frame. Vehicle was stationary, in my driveway. I had to pull my dogs paws/legs out physically. Obviously painful. On the ring video that captured this you can hear my dog whining and struggling. I was told they see this consistently and the manual states owner is responsible. This malfunction is dangerous and cased injury, yet it is seen consistently per auto service tech at dealership. What if it had been my 88 year old mother? this could very well lead to her death at her age, had she been the one injured. Never made aware of issue at time of sale. I believe this malfunction is dangerous. And to be told they see this consistently, why is not made a more important issue? in this case the injury was to an animal. It could have been a child or as stated, my 88 year old mother. The undercarriage is cleaned every time it is washed.
