October 11, 2018: Johnson Controls has responded to a lawsuit launched on October 3 by General Motors, which is claiming costs of more than $28 million from the battery giant.

“We have fully complied with all of our contractual obligations to General Motors and intend to continue to do so in the future,” a company statement said. “While we truly value our long-term relationship and partnership, we intend to defend the case vigorously.”

The action relates to the supply of batteries to General Motors between 2014 and 2016. GM claims JCI owes it the money for costs associated with warranty claims on batteries for models, which include Chevrolet, Buick, GMC and Cadillac during the period.

GM had named Johnson Controls as its supplier of the year in 2014.
