Around 1,000 workers are expected to be affected as GM attempts to reduce inventories.
General Motors has confirmed another shift elimination, laying off the late-night assembly crew at the Fairfax Assembly Plant in Kansas City.
The US automotive market has begun to stagnate in recent months, raising concerns that the post-recession industry boom may have come to an end. Many cars did not share in the good times as buyers flocked to SUVs and crossovers.
Dropping a shift at the Fairfax plant will help reduce output volume of the Chevrolet Malibu, which experienced a 29.9-percent drop in sales for the first five months of the year.
"Lower demand for passenger cars across the industry has caused us to adjust production of some models," the company said in a statement to The Detroit News.
To help keep inventories in check, GM has cut shifts at several other plants and extended planned shutdowns at others.
