And as I figured, I have sat and done my research, for Expeditions coming off the line the last week, they are being fully built, with the tracker showing the build is complete and waiting for shipment. I have even found a few that have the identical builds as mine. I knew once mine got put "Off Site" that it would sit there until they got around to it. I know someone we say that I could be wrong. But I have been able to pull the window stickers as well as the tracking for these vehicles. They were ordered after mine by a few months, and they went in to production within the last week and are built. One even went in to production yesterday, and is listed as built yesterday and is already awaiting shipment. Identical build as mine. Mine has been offsite for 20 days now. Can't tell me something is not wrong with this situation. On top of that, it was a dealer order, and not a customer order.
I'm not surprised by this. it is much more efficient to run the production line as it's designed. Also, for the missing motors or chips, all the cars go through a diagnostic check at the end to make sure the components are working within set tolerances. Obviously, if you're missing parts, that step cannot be completed either. It is far more inefficient to modify the line for these situations.
Ford does not want 3400 vehicles sitting off site. from an economics perspective, 3400 vehicles at ~40k each (build cost, not dealer/MSRP), you're looking at 130M in inventory sitting out in the elements. Even if that source is wrong, and the figure is half, that's still tens of millions in inventory they need to move.
Ford will more than likely run the line as designed, then shut it down for a week or so to catch-up on parts inventory, in that week, they will then install the missing components in the surplus 'built' inventory.
