Study shows connected cars share data with advertisers and tech firms

A Northeastern University and Consumer Reports study found that nearly all modern connected cars transmit user data not only to automakers, but also to advertisers, analytics companies, and major tech firms. By testing 21 vehicles from 19 brands and 30 companion apps, researchers uncovered extensive network activity—often far beyond core vehicle functions—and limited consumer control over this sharing. Some vehicles reached dozens of external domains, including for advertising purposes.

• Nearly all tested cars sent data to external companies
• Some cars contacted over 30 ad and analytics domains
• Apps linked to cars often increased data sharing
• Automaker, advertiser, and tech firm domains were contacted
• Consumers have little control over this data flow
