Passenger door opens when going over railroad tracks. I was traveling at only a few miles and I guess the tracks clicked it open some how. So now it seems that the door not only opens while driving at any speed but also if the car hits a bump or something on the roadway even at low speeds.. I was traveling on a county road.
