Check what information the car gathers, why it is used, who may receive it, which uses you can decline, how to request deletion, and what features stop working if you opt out.
What data might a connected car collect?
Depending on the vehicle and services you activate, information may include precise location, driving behavior, vehicle diagnostics, phone contacts or app information, voice, camera, and other sensor data. The Federal Trade Commission identifies location and biometric information as examples of sensitive data and warns that collecting, using, or disclosing it can threaten privacy and financial welfare. The precise data set is vehicle- and service-specific. FTC guidance, May 2024

The FTC’s practical privacy principle is to avoid unnecessary collection: “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.”

- Data categories: Identify whether the car or service collects location, driving behavior, diagnostics, phone information, voice, camera, or other sensor data.
- Purposes and retention: Separate data needed to provide a feature from analytics, marketing, or other secondary uses. Look for how long records are kept and whether the notice explains deletion or retention limits.
- Recipients and conditions: Check whether information may go to service providers, insurers, data brokers, dealers, law enforcement, or other parties—and under what conditions. These are possible recipients, not a claim that every automaker shares with each of them. Congressional Research Service overview
- Consent and choice: Find out whether enrollment is affirmative, whether separate purposes can be toggled independently, and whether you can withdraw consent after setup.
- Feature trade-offs: Ask which navigation, convenience, safety, remote-control, diagnostic, or emergency functions rely on data transmission or location access. Turning off a data flow may reduce or disable related services.
- Access and deletion: Look for routes to access, correct, or request deletion of account data. Also check how to erase paired phones and navigation history in the vehicle.
- Ownership transfer: Determine how to unlink accounts, remove personal information, and reset the vehicle before selling it or after buying it used.
Inspect the settings before you buy
- Ask to see the current privacy notice before activation. Request the notice for the exact model year, trim, market, and connected-services package, rather than relying on a general brand statement.
- Open the in-car privacy menu with the salesperson. Review available controls and ask what each one changes. The labels and options vary by vehicle, so verify them on the car you are considering.
- Ask which services work without consent or connectivity. Get specific about navigation, remote access, diagnostics, emergency functions, and any other features important to you.
- Check how to reverse enrollment. Confirm how to withdraw from each connected service later and how to submit data access or deletion requests.
- Re-check the online policy before delivery. Notices and service details can change; confirm the current version and the settings on the vehicle you will actually receive.
These steps reflect U.S.-focused guidance and examples. Privacy rules and service availability differ by market, so buyers elsewhere should check local requirements and the terms that apply in their country.
Examples show why model-specific checks matter
Subaru Starlink: the company’s description of opt-in telematics
In a response dated December 2023 and published in a congressional document in February 2024, Subaru told Senator Markey that Starlink telematics requires voluntary enrollment and consent, that users can cancel, and that they can request deletion. Subaru distinguished telematics from data remaining in the vehicle and data sent to third-party infotainment providers. This is Subaru’s account of its program at that time; it does not establish that every Subaru data flow is opt-in or that all models and services currently work identically.

Ford: reset and account disconnection depend on equipment
In its U.S. notice accessed in October 2026, Ford says available privacy controls depend on vehicle equipment and restricting transmission can affect connected services. Ford describes a master or factory reset as removing imported personal information and disconnecting modem-equipped vehicles from Ford or Lincoln accounts. It recommends resetting before transferring a vehicle and after acquiring a pre-owned one. Confirm the procedure for the particular car and account setup in its owner’s manual. Ford privacy notice

GM and OnStar: a resolved FTC settlement
In January 2026, the FTC announced a finalized order prohibiting the sharing of certain consumer data with consumer reporting agencies and requiring more transparency and choice. The announcement resolved allegations concerning earlier collection and sale of precise location and driving-behavior data without informed consent. It is an enforcement outcome, not proof that every current GM data practice is identical to the conduct alleged. FTC announcement

Use vehicle privacy reports as a starting point
The Associated Press describes Privacy4Cars’ free, VIN-based Vehicle Privacy Report as a summary of stated automaker practices. It can help you identify questions, but it is not a substitute for the current automaker notice or checking the vehicle’s actual settings. A report should not be treated as a privacy guarantee or a complete audit of every data flow. Associated Press buyer guide, November 5, 2025 · Privacy4Cars Vehicle Privacy Report
The AP guide reports that the Mozilla Foundation reviewed 25 automaker brands in 2023. That figure describes the size of that review, not the total number of car brands or a current ranking of specific models. No universal privacy winner follows from those examples: a useful comparison needs current, comparable evidence for the vehicles and market you are considering.
