Automakers reduced their North American production schedules in the third quarter by 26,900 units to 3,355,700 cars and trucks. That includes an estimated 36,900-unit shortfall in July, followed by a 14,200-unit increase in August and a modest reduction of 4,200 units in September. The revised schedule does not include changes from Ford, which is not expected to make major changes in its build schedule though some fine tuning is expected.
