General Motors Co. failed to warn U.S. drivers of a Cadillac sport-utility vehicle about a defect that causes headlights to malfunction because moisture gets inside the glass, creating a safety hazard for more than 300,000 of the cars, according to a lawsuit filed Tuesday in Detroit.

Three plaintiffs in the federal suit are seeking class-action status, which would allow them to pursue claims on behalf of anyone who bought or leased Cadillac SRXs for model years 2010 to 2015. Exterior seals on the headlights erode prematurely, allowing moisture in and causing light beams to dim or fail, they said in the court filing.
