Your Car Is Spying on You. A New Study Shows Just Who It’s Telling Your Secrets To.

Every car tested in a recent study sent data to third parties — a silent, invisible pipeline of personal information flowing from your dashboard to advertisers, trackers, and analytics firms. That’s not just invasive; it’s the new normal. Researchers from Northeastern University and Consumer Reports uncovered that all 21 vehicles across 19 brands shared data externally, and more than half connected to advertising or data-tracking domains. Seven companion apps went further, transmitting phone numbers, VINs, and exact locations — the kind of details that don’t just identify your car, but you.

What’s most alarming isn’t just the scale, but the lack of transparency. Many drivers don’t realize their car is constantly reporting back — and opting out isn’t easy. The FTC’s recent action against General Motors and fines against Ford and Honda underscore a growing regulatory push, but the damage may already be widespread. In my experience guiding founders through investor pitches, I’ve seen how data privacy gaps can sink valuations — yet here, entire industries operate on shaky ethical ground.

Some automakers are responding: Honda wiped location data and updated its app, a move toward accountability. But others still defend data harvesting as legal, which misses the point. Legal doesn’t always mean trusted. As more devices become data collectors, consumer trust becomes the real currency. For entrepreneurs building tech-driven products, this is a cautionary tale: if you’re not transparent about data use, you’re building on a foundation investors will question.

The road ahead demands better defaults — privacy by design, not by demand. Until then, assume your car is listening.
