The sale of electric vehicles was slow in January 2014, reports The Detroit News.
Early-year, electric vehicles are often hurt because some owners rush to buy them in December to take advantage of tax credits of up to $7,500 before the tax year expires.
But poor weather and lower gas prices also were factors.
General Motors said sales of its plug-in hybrid Chevrolet Volt fell 19.5% in January to 918, down from 1,140 in the same month last year.
In January, GM also sold 41 Cadillac ELR vehicles, its upscale plug-in hybrid.
According to Ford Motor, sales of its plug-in C-Max were down 48% to 1,418, while Toyota Motor reported an 8.1% drop in sales of its plug-in Prius, to 803.
However, Nissan Motor said that sales of its all-electric Leaf nearly doubled in January to 1,252, up 93% over the 650 sold in January 2013.
