To choose a car that collects less data, compare the privacy practices and controls for the exact model, model year, trim, market, and connected services—not just the automaker’s general privacy promise. Check what data the car collects, why it is used, who may receive it, how to opt out or request deletion, and which features stop working if you do.
Why car privacy deserves a closer look
Connected vehicles can collect sensitive information, including location and biometric data. The Federal Trade Commission warns that how companies collect, use, and disclose such information can affect consumers’ privacy and financial welfare. The exact data set depends on the vehicle, its equipment, and the services you activate. The FTC’s May 2024 guidance puts the basic principle plainly: “The easiest way that companies can avoid harming consumers from the collection, use, and sharing of sensitive information is by simply not collecting it in the first place.” FTC guidance on connected-vehicle privacy.
Data may be used for a feature you request, but policies may also describe analytics, marketing, or other purposes. Depending on the automaker’s terms and the circumstances, information could be shared with service providers, insurers, data brokers, dealers, or law enforcement. Do not assume every manufacturer shares every kind of data with every recipient; read the specific notice and its conditions.
What to compare before you buy
Ask the dealer to show you the privacy notice and settings for the vehicle you are considering, before activating connected services. Compare the following details across the exact models and service packages—not across brand reputations alone.

| What to check | Questions to ask |
|---|---|
| Data categories | Does the vehicle or service collect precise location, driving behavior, diagnostics, phone contacts or call information, app data, voice, camera, or other sensor data? Which categories apply to this vehicle’s equipment? |
| Purpose and retention | What information is necessary to deliver a feature? Is it also used for analytics, marketing, or other purposes? How long are records retained? |
| Recipients | Does the notice name service providers, insurers, data brokers, dealers, law enforcement, or other third parties? Under what stated conditions can information be disclosed? |
| Choice and withdrawal | Must you affirmatively enroll? Can you toggle individual purposes separately? Can you withdraw consent later, and how? |
| Feature trade-offs | Which navigation, convenience, safety, remote-control, diagnostic, or emergency features rely on data transmission or location access? What stops working if you decline? |
| Access and deletion | How can you request access, correction, or deletion? Can you erase paired-phone data and navigation history in the vehicle? |
| Ownership transfer | How do you unlink accounts and remove personal data when selling or buying the vehicle used? |
Policies and controls can vary by model year, trim, market, equipment, and service. Check the latest online notice as well as the in-car menu: a policy may cover multiple models or service packages, while a specific vehicle may have different available controls. The practical advice in the Associated Press’s November 5, 2025 buyer guide is to inspect in-vehicle settings and understand their trade-offs; its coverage reports that Mozilla Foundation reviewed 25 automaker brands in 2023. That is the size of that review, not a current ranking of all car brands. AP buyer guide to car privacy.
Check what an opt-out actually changes
Turning off a data flow can also turn off the feature that depends on it. Navigation and other connected services, for example, may rely on location or data transmission. Ask the dealer to demonstrate which services work without enrollment or consent, and distinguish essential vehicle functions from optional connected features. The answer should be specific to the vehicle’s equipment and service package; do not assume a setting has the same effect across a manufacturer’s lineup.

Read whether consent is bundled or whether you can decline particular purposes independently. Confirm that you can withdraw a choice after setup and find out whether that change takes effect in the car, the connected app, or through a separate account or customer-service request. For U.S. buyers, state and federal rules may shape available rights and practices; this guidance is not a substitute for checking rules in your market.

Subaru Starlink
In a response from December 2023 published in a congressional document in February 2024, Subaru said Starlink telematics requires voluntary enrollment and consent, that users can cancel, and that users can request deletion. Subaru distinguished telematics from information remaining in the vehicle and information sent to third-party infotainment providers.
