The FTC has reached a proposed settlement with GM, prohibiting the automaker from sharing customer geolocation and driving behavior data.

“GM monitored and sold people’s precise geolocation data and driver behavior information, sometimes as often as every three seconds,” FTC Chair Lina Khan said in a statement. “With this action, the FTC is safeguarding Americans’ privacy and protecting people from unchecked surveillance.”

The Federal Trade Commission has taken action against General Motors and OnStar for allegedly sharing details about drivers to third parties without their consent.

General Motors reached an agreement to settle allegations that the automaker shared drivers’ locations and behavior data without their consent, the Federal Trade Commission said.

GM sold precise driver data collected through OnStar and a discontinued feature called Smart Driver. The information could have hiked insurance rates.
