Other Fuel System Tank Assembly problems of the 2018 Ford Edge

Car was in motion on a paved state of nebraska highway. I heard a load pop, did not see anything in road or feel that the car hit any kind of road hazard. Was two miles from home, no warning light came on. When parked I did smell gas but could not determine where it was coming from because there was a light rain. In the morning all fuel had drained out on the ground and down the street. Had it towed to shop, they found a hole in the gas tank and determined it was a road hazard collision. Ford seems unable to provide a replacement tank and it appears it will likely be months before they can get one in. Just concerned that this tank maybe prone to holes caused by perhaps just a rock being thrown up under the tank. This could have been a very bad situation as I am a smoker and often sit in my car and have one before going in the house. I am also concerned that Ford can't provide a replacement tank, and several places I have check say the tank for this car has been discontinued. Possible problem with the existing tank that they are not disclosing. Why should it take 3 months to get a replacement gas tank?.
