Your car and its mobile app are probably handing over all kinds of data to tech companies

When you hand over the keys to a modern car, you’re also handing over a treasure chest of data. A fresh study from Northeastern University, done with Consumer Reports, proved that the connected‑car ecosystem is leaking that treasure to the same tech giants that dominate our digital ad space. As a founder who runs real hosting infrastructure, I’ve seen how data pipelines get hijacked for profit, and this is a textbook case of the same thing happening on four wheels. The takeaway for independent hosting providers, OEMs, and anyone building a privacy‑first product is simple: you cannot trust “out‑of‑the‑box” telemetry. You have to own the data flow, audit every third‑party endpoint, and be ready to say no when a vendor tries to sell you a cookie‑filled link.

Scope of the leak: cars, apps, and the tech giants

The researchers tested 21 late‑model vehicles from 17 automakers – a mix that included big names like GM’s Cadillac and Chevrolet, Ford, Lucid, Rivian, Tesla, and Toyota. They also dissected 30 companion mobile apps. The result? Nineteen of the 21 cars sent traffic to at least one third‑party server, and seven of the apps handed over sensitive data – VINs, emails, phone numbers, and precise location – to advertising and tracking firms.

The third parties weren’t obscure data brokers; they were household names: Adobe, ContentSquare, Google, Microsoft, Meta, Snap, and Yahoo. When the companion app was paired with the vehicle, exposure roughly doubled, meaning the app layer is a massive amplification point for data leakage.

Why the data matters: profiling and resale

When advertisers and data brokers get a VIN, a driver’s exact location, and contact details, they can stitch together a granular profile that goes far beyond “I drive a sedan.” Those profiles are sold not just to ad networks but to insurers, banks, and other financial services that already have a vested interest in your driving habits. The study notes that the same data ends up in the hands of multiple downstream buyers, making it almost impossible for a consumer to shake the trail.

From a business‑risk perspective, that means any company that integrates a connected‑car platform inherits the liability of that data pipeline. If a breach or a regulatory audit uncovers that you’ve been feeding data to Meta or Snap without clear consent, you could face hefty penalties and a smashed brand reputation – exactly the kind of nightmare that keeps founders up at night.

OEMs’ response: blame‑shifting and token fixes

All manufacturers were contacted, and every one except Honda tried to shift the blame. Honda, after being nudged, actually ordered its vendor Amplitude to delete all geolocation data it had collected – a rare instance of a brand taking concrete action. The rest of the OEMs either pointed fingers at consumers for not reading the fine print or simply dismissed the findings.

This pattern mirrors what we see in the broader tech industry: vendors deflect responsibility, leaving the end‑user to shoulder the risk. For independent hosting providers, that’s a red flag. If a partner can’t own up to a data‑privacy issue, you can’t rely on them to protect your infrastructure either.

The hidden cost of “convenient” features

Features like remote start, unlock, and over‑the‑air updates are marketed as convenience, but they open a backdoor for telemetry. The study makes it clear that avoiding the data bleed would require either disabling those features or, more realistically, using a vehicle that doesn’t ship with a pre‑installed data‑sharing stack.

From an operational standpoint, that’s a nightmare for fleet managers and enterprise customers. You can’t simply tell a driver to turn off Wi‑Fi on their car. Instead, you need a solution that sits between the vehicle and the cloud, filtering outbound traffic and stripping out any identifiers that aren’t essential for the service you actually need.

What this means for hosting and cloud providers

Most of the traffic from these cars ends up at the same ad‑tech clouds that power the rest of the internet. If you’re running a data center or offering edge services, you’re likely already hosting some of those third‑party endpoints. That puts you in the crosshairs of regulators who will soon start asking: “Why is my data being sent to Google or Meta from a vehicle?” The answer, if you’re honest, will be “We didn’t know.” That’s not a defense.

Our own experience running a carrier‑grade hosting platform tells us that the moment you let a third‑party SDK into your stack, you inherit its compliance obligations. The safer play is to demand that OEMs give you a clean data feed – no embedded analytics SDKs, no hidden pixels – and then apply your own, audited telemetry layer.

Actionable steps for founders and providers

First, audit every API call that leaves your vehicle‑connected platform. Use a packet capture tool to map out which domains are being contacted. If you see any of the big ad‑tech names, flag them immediately. Second, negotiate contracts that require vendors to disclose all third‑party data flows and to give you the ability to block or delete that data on demand.

Third, build a privacy‑by‑design gateway at the edge. A lightweight proxy that can strip out VINs, exact GPS coordinates, and personal contact info before the traffic hits the wider internet will dramatically reduce exposure. Finally, educate your customers – whether they’re fleet operators or individual drivers – about the trade‑off between convenience and privacy. Transparency builds trust, and trust is the currency that keeps a hosting business alive when the hyperscalers start charging premium rates for “secure” data pipelines.

Bottom line: data is the new fuel, and you control the pump

The Northeastern study is a wake‑up call that the connected‑car market is still a wild west of data harvesting. The same ad‑tech giants that dominate web tracking are now sitting on the dashboards of our cars. If you’re a founder building a product on top of that ecosystem, you either become complicit in the data‑selling game or you take the hard road of building a clean, auditable pipeline.

My advice? Treat every third‑party endpoint like a potential breach. Vet, block, or replace it. Demand that OEMs give you raw sensor data without the attached advertising SDKs. And, most importantly, remember that the only way to protect your customers – and your business – is to own the data flow from the moment the car turns on. Anything less is just handing the keys to the data thieves.
