We regularly hear stories about companies that are selling your sensitive personal information including your location data to the highest bidder. The latest culprit appears to be General Motors.The Federal Trade Commission alleges that GM and Onstar GMs subscription-based in-vehicle safety and security system collected, used, and sold drivers precise geolocation data and driving behavior information from millions of vehicles without adequately notifying consumers and obtaining their consent. On Thursday, the agency issued a proposed order to ban the company from selling such data to consumer reporting agencies for five years.In its complaint, the FTC alleged that GM used a misleading enrollment process to get consumers to sign up for Onstar. Some users reported being unaware that they signed up for Onstars Smart Driver feature, which promised to use driving data to help drivers improve their vehicles performance and encourage safer driving.GM monitored and sold peoples precise geolocation data and driver behavior information, sometimes as often as every three seconds, FTC Chair Lina M. Khan said in a statement.This is the latest issue to beset the carmaking giant in recent weeks. Last month, GM pulled the plug on funding its autonomous vehicle unit Cruise, a company into which GM has invested more than $10 billion.Thursdays settlement with the FTC follows an investigation by The New York Times Kashmir Hill, who found GM had been collecting details about its customers driving habits including every instance of hard braking, late night driving, and speeding and selling the records to insurance companies and third-party data brokers. The result was that drivers began seeing higher insurance premiums, but couldnt figure out why.The potential misuse of customers data goes beyond increased insurance premiums. A persons geolocation data can reveal the most intimate details of a persons life, including where they live and work, and whether they visited a medical facility or place of worship. In the wrong hands, location data poses a serious danger to, for example, abortion seekers across the country.As part of the FTCs proposed order if approved by a court GM and Onstar will be banned from disclosing data to consumer reporting agencies, and would also need to obtain affirmative express consent from consumers before collecting any vehicle data in the future. The automaker would also need to allow customers to obtain and delete their data, as well as limit the data collection from their vehicles.Since its still a proposed order, the agreement will be subject to a 30-day public comment period before a final ruling goes into effect. TechCrunch has reached out to GM and the FTC for additional information and will update if we hear back.
