New vehicle sales in the U.S. are expected to have fallen slightly in the third quarter, even with improvement in September. But there are warning signs that consumers' appetite for expensive new cars, trucks and SUVs may be waning.
Edmunds.com says it expects sales to have fallen just under 1% in the period from July through September when the numbers from automakers are totaled up on Monday. Multiple companies reported sales declines for the quarter, with General Motors as a notable exception.
