Car Will Not Start problems of the 2018 Ford Expedition

The vehicle failed to start 3 different times. The first time was immediately after purchase of the vehicle - it started after 30 min and was taken back to the dealership. They replaced the battery and no issues until 4 days then it occurred again. The vehicle was stopped and parked overnight and wouldn't start the next morning. The battery had enough power - jump starting didn't help. The 3 tow truck was finally called into tow the vehicle to the Ford dealership. They replaced the ignition switch and then took the vehicle back up to the purchasing dealership. They did a full review of the vehicle and didn't find any further problems. Then 4 weeks later it happened again where the vehicle would not start following sitting for a couple of hours. Again it took 4 tow trucks to come to get the vehicle to the Ford dealership. The problem was the vehicle wouldn't stay in neutral to be towed it would always return to park. The dearship then replaced the started and said it was then taken care of and won't happen again. The events were sept 4th - purchase vehicle - 1st episode, sept 8th - 2nd episode, November 19th - 3rd episode.
