Purchased my Ram 2500 Laramie w/6.7 Diesel three weeks ago. My wife, who's visually impaired, nearly fell out of the truck, when the power running board didn't deploy when she opened her door. I exited the truck and went around and tried opening and closing the door (front and rear) and the board would move about 20% and then return to the stowed position. Has anyone else had any problems?
