Connected vehicles are transforming daily mobility with GPS, Wi-Fi, remote access and companion apps. Yet a new peer-reviewed investigation led by Northeastern University shows that these conveniences can also expand the flow of personal information across the digital ecosystem.
Connected features, wider data trails
The research examined 21 recent-model vehicles from 17 manufacturers and reviewed 30 companion mobile apps. It found that 19 of the 21 vehicles communicated with at least one third-party service.
In seven apps, researchers identified the transfer of sensitive details including vehicle identification numbers, email addresses, phone numbers and precise location data to companies associated with analytics, tracking or advertising.
When a mobile app was paired with its vehicle, exposure to advertising and tracking services roughly doubled. Combining several data points can enable highly detailed consumer profiles, potentially extending beyond vehicle use into broader commercial services.
A growing focus on transparent mobility
The study highlights how carmakers, software vendors and app developers are shaping a more connected mobility experience. Some manufacturers noted that external pages opened through companion apps may use cookies, while Honda updated elements of its data collection approach after receiving the findings and requested deletion of geolocation data held by a vendor.
For drivers, the findings reinforce the value of reviewing app permissions, connected-service settings and privacy options when activating in-car features. As vehicles become software-defined platforms, clear consent tools and understandable data controls will be central to maintaining trust.
The next phase of smart mobility may be defined not only by seamless connectivity, but by privacy-by-design systems that give drivers greater visibility and control over their digital footprint.
