General Motors will close a Detroit factory for six weeks starting in mid-November due to weak sales, The Wall Street Journal reported Thursday, citing unnamed sources.

The move will affect 1,500 workers who work on four models that are in low demand among consumers: the Buick LaCrosse, the Cadillac CT6, the Chevrolet Volt and the Chevrolet Impala, the paper said.

"As a result of declining overall industry volumes, the Detroit-Hamtramck plant will be making schedule adjustments to keep supply and demand in balance," said a GM spokesman in a statement sent to CNBC. "Effective October 20, the plant will operate under a reduced production schedule. This action will help maintain more stable production."

The Detroit-Hamtramck plant will likely produce 20 percent fewer vehicles once production resumes in 2018, the Journal said.

GM declined to comment to the Journal and was not immediately available for comment to CNBC.
