3. Chevrolet Silverado (402,111 units sold)
The Silverado has long occupied the number-two spot in the U.S. sales rankings, but things aren’t looking good for Chevy’s light- and heavy-duty pickups so far in 2019. Sales of the light-duty model have dropped by 0.6 percent, while the heavy-duty truck is down 12 percent. This allowed a surging Ram pickup range to surpass it through September.
