The automaker said it was petitioning to overturn the California Air Resources Board agreement to "relieve Stellantis of the competitive disadvantages arising from our continuing exclusion and to preserve our ability to best serve our customers by fairly allocating our products to all states."

Ford, Honda, Volkswagen and BMW struck a voluntary agreement with California on reducing vehicle emissions. Stellantis has since sought to join but been rebuffed.
