The 'sufficient resistance' is high enough to mess up a child's finger.
But I think that's across the board with every manufacturer with those kind of doors.
I can attest to the truth in the statement from first hand experience. Not with a pacifica but with another minivan, and it takes a considerable amount of force to stop the door from closing. The sufficient resistance required is usually not something that a small child can muster, which often makes it a safety hazard. I hope you get it fixed before a child gets hurt
