Toyota saw US sales drop 0.6 percent to 2.4 million, but the company highlighted strength in its popular Camry sedan, the RAV4 crossover and SUVs.
Mustafa Mohatarem, GM's chief economist, forecasts 2018 total vehicle sales (including medium and heavy trucks) to exceed 17 million units for the fourth year in a row.
Ford's sales fell 1.1 percent to 2.6 million compared to 2016, but it reported a surprise increase in December, fueled in part by the continued success of the F-Series pickups and other large vehicles. Fiat Chrysler reported a decline of 8 percent compared with 2016. Cadillac and Lexus both saw their sales drop 8 percent previous year; Lincoln sales plummeted 17 percent in December.
Honda's USA sales rose 0.2% for the year to 1.6 million.
Toyota Motor North America reported December sales dropped 8.3% from December 2016 on a volume basis.
Record sales were also posted by nearly all luxury vehicle brands, including Audi, BMW, Mercedes-Benz and Porsche.

A few automakers say luxury sales have struggled.
Ford's overall sales increased by 0.9% in December, but the automaker, which is more and more dependent than ever on the success of its trucks and sport-utes, saw full-year sales drop 1.1% led by a 14.2% decline in vehicle sales.
GM also published its December sales figures Wednesday, which showed total sales were 2% up on the same month in 2016.
Despite the usual year-end push to get vehicles out the door, most automakers endured tough sledding in December.
And, the USA auto industry continues to enjoy strong demand for larger vehicles, including SUVs, pickup trucks and "crossover" models. Chevrolet was offering $11,000 off a 2017 Silverado pickup last month. The company's Acura luxury division fell 12.2% in December and 4.2% for the full year. Low unemployment and rising consumer confidence are expected to boost demand this year.
