Volkswagen sales declined at a stronger clip to begin the new year as the company continues to struggle with the scandal over diesel emissions.
Federal regulators in September found that hundreds of thousands of VW vehicles were equipped with software to manipulate emissions levels during official testing.
The German automaker could face billions in fines and was hit hard by sales declines in subsequent months.
November’s sales were down 25 percent compared to the previous year, but the drop eased to 9 percent in December.
Last month, however, VW sales fell by 15 percent in the U.S. according to numbers released Tuesday.
The company attributed the totals to rough weather in the Northeast and seasonal variations in its fleet business, and noted that deliveries of its Tiguan compact SUV set a January record.
Other automakers, meanwhile, reported mixed results for the beginning of 2016 after a record 2015.
Fiat Chrysler sales climbed by 7 percent for the company’s best January in years, while General Motors sales increased by just 0.5 percent and Ford sales declined by 3 percent.
Toyota sales fell by 4.7 percent and Honda sales fell by 1.7 percent, although the Honda division remained flat. Nissan, meanwhile, saw sales grow by 1.6 percent.
Those six companies comprised more than 75 percent of the U.S. auto market in December, according to numbers from The Wall Street Journal.
Automakers noted that January 2015 included two fewer selling days and one less weekend than the previous January, along with rough winter weather.
