American automakers are out shouting about their latest sales figures this week after the second quarter of the year ended last weekend. Light vehicle sales in America fell 1 percent during the three-month period as a computer glitch struck The ability of American dealers to sell cars.

Despite stagnant sales across the country, some automakers weathered the period better than others, with a report of Automotive news with the highlight being performances from GM, Honda, Subaru and Mazda, which all posted sales increases for the quarter. The fortunes were less rosy for Toyota, Stellantis, Hyundai, Kia and Nissan, which all posted declines in deliveries for the three-month period. Automotive news explains:

The U.S. new-car market lost some steam in the second quarter as affordability, higher prices and higher borrowing costs continued to weigh on consumers, even as dealers scrambled to salvage sales after a coordinated cyberattack took key software offline.

General Motors, behind higher demand for large trucks and electric vehicles, posted a slight increase in U.S. sales in the second quarter. GM and other automakers said some deliveries may be delayed or not recorded until the third quarter in the wake of cyberattacks at CDK Global in late June that derailed month-end results.

The biggest sales for the period were at General Motorswhich sold 691,680 vehicles in the quarter. This was followed by Toyota, which sold 621,549 vehicles and Hyundai-Kia, which delivered 438,602 models.

The biggest percentage gains for the quarter came from a rather surprising source, however, with Fiat posting triple-digit growth as a result of the launch of its all-electric 500 in the US.

Despite some positive stories from the quarterly results, sentiment was dampened by a computer glitch that hampered dealers’ ability to sell cars starting June 19. Automotive news adds:

The new vehicle market, which rose 5.6 percent in the first quarter, was on track for a more modest increase in June, with the widespread cyberattack on CDK denting final volume. Many sales will be recorded or recovered in July.

The outage, which began June 19, hampered deliveries during what is typically the industry’s strongest period for new-vehicle sales: the end of the month. Many automakers and dealers also pitch summer and Fourth of July holiday promotions to drive traffic and generate sales.

But now it appears that the situation is improving and that the outage will be long gone by the time the third quarter sales figures are announced in a few months.
