GM’s Engineering Center Closed Over Legionnaires’ Disease

General Motors Co.’s Cole Engineering Center north of Detroit will be closed until at least Sept. 22 after two employees tested positive for Legionnaires’ disease, temporarily idling the site where about 10,000 people work on future vehicles and technologies.

GM shut down the facility in Warren, Michigan, on Sept. 10. Regular bacteria testing hasn’t found any issues, and the facility hasn’t been confirmed as the source of the infections, the company said in a statement.
