While exiting the vehicle from the front passenger door, I put my left hand on the door frame to close the front door. Simultaneously, the passenger in the rear passenger side exited the vehicle and closed the door. One of my fingers got caught between the door frame and the door and severed part of my my finger off. While I understand closing the door on my hand is not Jeeps fault, the normal result of closing the door on a finger is not instant amputation! I used a stick to see if I could replicate the results, and 100% of the time the door snapped the stick when placed above the door hinge. If that had been a childs hand, it would have cut it clean off.
