There is no proven privacy-friendly make or model for every buyer. Compare the exact vehicle—model year, trim, market and connected-service setup—before you buy. Read its current privacy notice and owner’s manual, check the in-car controls, and find out what data is collected, why, who receives it, how long it is kept, and what changes if you opt out.
Why car privacy depends on the exact vehicle
Connected cars may collect location, trip history, driving behavior, diagnostics, voice or image data, identifiers, and information from paired phones or infotainment apps. Which data is collected—and when—depends on the vehicle’s equipment, software, account setup and enabled services.
A brand-wide privacy policy or ranking can point to questions worth asking, but it cannot establish how a specific car is configured. Mozilla Foundation’s September 2023 review gave all 25 major brands it assessed failing privacy marks. That review examined public privacy and security information; Mozilla says it did not buy vehicles and test them in a lab. Treat the findings as a warning to inspect the terms, not as a current ranking of 2026 cars or a technical test of a particular model. Mozilla’s car privacy guide explains its approach.
What to compare before you buy
Get the current privacy notice and owner’s manual for the vehicle’s model year and market. Compare the specific trim and connected-service package, not just the name on the badge.

| Check | What to look for |
|---|---|
| Data collected | Whether the notice names precise location, trip history, driving behavior, voice, images, diagnostics, contacts, app use and identifiers—and whether collection is continuous, trip-based or feature-triggered. |
| Purpose and recipients | Whether data is used to provide requested features, support safety, improve products, advertise or calculate driving scores; and whether it may go to affiliates, service providers, insurers, data brokers or government agencies. |
| Consent and controls | Whether collection is opt-in, whether location and driving behavior have separate controls, and whether choices are available in the car, mobile app or account portal. |
| Retention and account exit | How long data is kept, and whether you can access, download, correct or delete it, close an account, cancel services and remove stored information before transferring ownership. |
| Feature trade-offs | Which remote access, navigation, emergency response, diagnostics or infotainment features stop working if you disable a modem, location, voice or phone integration. |
| Evidence quality | Whether a claim comes from a current notice and manual for your exact vehicle, or from a brand-level review of published policy language. |
Questions to ask the dealer or automaker
- Which data does this exact vehicle collect by default, and what starts only after I create an account or enable a service?
- Is precise location collected continuously, during trips, or only when I request a feature?
- Does the company share or sell data? Ask which categories of recipients may receive it and whether insurance, advertising, analytics or driving-score programs have separate permissions.
- Can I decline connected services and still use core vehicle functions? What stops working if I disable modem connectivity, location, voice features or phone-app integration?
- How can I review, download, correct, delete or opt out of data collection? Are the controls in the vehicle, a mobile app or an account portal?
- What data remains in the car after I disconnect my account, and how do I remove paired phones, contacts, navigation destinations, garage access and driver profiles?
- Do the privacy terms differ in my country or state? Can you provide the current notice and owner’s manual before purchase?
Check the settings and their trade-offs
Test the vehicle’s privacy menus and review its manual before activating connected services. Look for separate choices for location, driving data, app permissions and account-linked features; do not assume that switching off one option disables every data flow. The manufacturer’s notice should explain what a choice covers and which features depend on it.
For example, Ford’s US privacy notice describes possible location and app-related data flows and says available permissions and connectivity choices depend on the system and vehicle. Ford’s 2025 corporate article says the company does not sell connected-vehicle data and that current vehicles can be disconnected. Those are Ford’s statements, not independent verification of every vehicle’s settings or terms; check the documentation and controls for the specific car. Ford’s US privacy notice is a starting point.

Disabling collection may mean giving up remote access, navigation, emergency response, diagnostics or other services. Decide which features you need, then ask exactly what remains usable without an account or data sharing. Avoid treating a general “privacy” toggle as proof that all collection has stopped.
What recent US guidance and rules mean for buyers
In January 2026, the Federal Trade Commission finalized an order specific to GM and OnStar. Over the order’s 20-year term, it requires affirmative express consent for covered connected-vehicle data collection, use or sharing, with exceptions that include emergency first responders. It also requires ways for US consumers to request access and deletion, disable precise-location collection when the vehicle has the necessary technology, and opt out subject to limited exceptions. The order bars specified geolocation and driver-behavior data disclosures to consumer reporting agencies for five years. These requirements apply to GM/OnStar under that order; they are not a rule for every automaker or jurisdiction. Read the FTC’s announcement.

The FTC’s May 2024 guidance says collection, use or disclosure of location can be unfair in some circumstances, and that companies should not assume they may monetize personal information beyond what is needed to provide the requested product or service. It is enforcement guidance, not a complete account of every federal or state privacy law. Read the FTC’s guidance.
Dealer-arranged financing or leasing raises a separate issue: the FTC says the Gramm-Leach-Bliley Act Privacy Rule applies to certain personal information collected in connection with those transactions. Its FAQ distinguishes cash buyers and people who arrange financing independently; it addresses dealers’ financial information and does not resolve every question about connected-car data. See the FTC’s auto-dealer FAQ.

Buying used or preparing to sell
During a used-car inspection, test the privacy menus and ask for the reset procedure. Confirm that previous-owner accounts and paired devices have been disconnected, and check whether an embedded connectivity subscription is still active.
Before selling, returning or transferring a connected car, remove your account and clear stored preferences and imported data, including phones, contacts, destinations, garage access and driver profiles. Ford specifically advises using Reset for modem-equipped vehicles; follow the instructions for your own make and model rather than assuming the same reset process applies to every car. Ford’s privacy notice includes its guidance.

Use vehicle reports as leads, not guarantees
The Associated Press reported that Privacy4Cars offers a VIN-based vehicle privacy report that can summarize practices such as location collection and potential sharing with insurers, data brokers or law enforcement. A report can help you identify what to investigate, but confirm that the service is currently available and covers the vehicle’s market. It does not replace the manufacturer’s current notice, manual or in-car settings. Read AP’s description.
