Production at three Stellantis assembly plants in Europe has been stopped for several days due to a strike at a plant run by contractor MA France.
"Three sites have seen a production halt since the start of the week," a Stellantis spokesperson said on Thursday.
Two of the plants are in France at Poissy and Hordain, and the third is in Luton, England.
MA France, a division of Italian group CLN, specializes in stamped metal components.
