Priority codes mean nothing these days, my priority code 19 2022 was built before quite a few priority code 2 2022 Expeditions in May, I highly suspect that it's a matter of commodity food-chain that causes one Expedition to be built before another. If they do not have all of the parts in house, the trucks are no longer being scheduled on the line, to wait in a holding area (Ford has over 50,000 such vehicles in holding areas across the country right now, as reported by Ford Corp) for those missing items to be delivered. 100,000 sub assemblies and assembly pieces go in to making an Expedition, if one major item is missing, that truck is getting bumped further down the line, no matter if it is a priority 2 or a priority 19....Yes, it really is that simple these days.
You can call and complain, threaten to pull your order and deposit, but until the supply chain woes get better, it will not make a bit of difference.
