UNDATED (AP) — Auto makers are reporting their December and full-year sales today. Car shopping site Edmunds.com expects 1.7 million cars were sold, which would make last month the biggest December in history for the auto industry. It also expects the reports will show 2015 was the biggest sales year in the industry's history.

General Motors said its U.S. sales rose 6 percent and Ford's sales increased 8 percent. However, those totals fell short of analysts' projections, and shares of GM fell 90 cents to $32.41 and Ford declined 41 cents to $13.56.

Elsewhere, Fiat Chrysler sales grew 13 percent, Toyota's sales rose 11 percent and Nissan's sales climbed 19 percent.
