Your Car May Be Sharing More Data Than You Think
A new study by researchers from Northeastern University and Consumer Reports found that connected cars continue to pose serious privacy risks for drivers. The team analyzed 21 vehicles from 19 brands and discovered extensive data sharing with advertisers, analytics firms, and major technology companies. While all connected cars communicated with their manufacturers, some models contacted dozens of additional third-party domains. Tesla's Model 3 was identified as one of the most aggressive data sharers, reaching numerous advertising, tracking, and infotainment-related services. Researchers also found that companion mobile apps often exposed users to even more trackers, with apps from General Motors, Toyota, and Nissan among the most data-hungry. Many automakers argued that data-sharing practices are covered by privacy agreements and user consent mechanisms, though critics say these policies remain overly complex and restrictive. The study highlights how declining data collection can sometimes reduce vehicle functionality, leaving consumers with limited privacy choices. One positive outcome emerged when Honda reportedly changed some of its practices and stopped sharing precise location data with at least one tracking company after being contacted by researchers.
