Ford Motor Co. said Monday that shortages of certain parts will result in a higher-than-planned number of unfinished vehicles in its inventory.

“Vehicles on wheels” have been built but are still in need of some parts, the company said. Ford said it expected to have about 40,000 to 45,000 such vehicles in inventory at end of the third quarter. Those vehicles “disproportionately include high-demand, high-margin models of popular trucks and SUVs,” Ford said.
