The U.S. carmaker had been harvesting drivers' data that was of particular value for insurers keen on better assessing the risk posed by policyholders.

An investigation by the Federal Trade Commission determined that consumers had not been aware that the automaker was providing their driving information to data brokers.

The Federal Trade Commission has taken action against General Motors and OnStar for allegedly sharing details about drivers to third parties without their consent. The agency launched an investigation into the automotive company after The New York Times found that GM had collected data about customers' vehicle use and sold it to third-party platforms used by insurance companies.
