The largest U.S. automakers reported lagging sales for the first half of 2017 in their latest monthly disclosures.
Among the nation's top six auto manufacturers, five reported sales in that six-month window below the record pace of 2016, which will likely fuel expectations that full-year sales will fall short of last year's totals.
The "Big Three" domestic automakers — General Motors, Ford and Fiat Chrysler — on Monday reported lower June sales as well as six-month totals below last year's pace.
Their top Japanese counterparts, meanwhile, reported monthly sales increases in June, but only Nissan reported a year-to-date increase in sales.
GM, which recently acknowledged that its 2017 sales would likely fall short of the previous year's total, reported a 5 percent decline in sales last month and a 2 percent decrease over the first six months of the year.
Ford's sales fell by 5 percent and 4 percent, respectively, over those windows, and Fiat Chrysler reported 7 percent sales declines for the month and the year-to-date.
Toyota and Honda, meanwhile, reported sales increases of 2 percent and 1 percent, respectively, last month. Toyota's first-half sales, however, were off by nearly 4 percent. Honda sales were generally flat over the first six months of the year.
Nissan saw a 2 percent increase in June sales and a nearly 3 percent sales increase for the first half of the year.
Those six companies comprised more than 75 percent of the U.S. auto market in May, according to numbers from The Wall Street Journal.
The auto industry in general saw sales of larger trucks and SUVs at the expense of smaller cars; Nissan's truck sales increased by 21 percent in the first half of the year, which helped outweigh a 12 percent decline among its cars.
