I was taking my child to school for a field trip. We were in the parking lot for approx. 20 min with the engine off. Then out of nowhere a big gush of gray/black smoke appeared. I immediately got myself and children out of the car and proceeded to call 911. At this time the 2 bus drivers came and ask me to pop my hood assuming it was my car running hot when they lifted the hood there was flames. They got a fire ext. And put it out. I proceeded to find a way to get home and get my other children to school. I then called my mechanic and asked him to meet me at my truck. He inspected it and determined the sw asy and brake fluid lines had burned and melted. He talked to a couple of his friends whom own junkyards and they told him in the last year they have had 10 or so Expedition come in burned from the same problem. I called Ford and have had no response. I believe this is a man. Defect that needs to be looked into. Any help or comments would be appreciated because it could have turned out worse than what it did if I didn't have bus drivers there to help.
