Limit Car Data Sharing: Privacy Settings Guide

Modern cars collect a lot of data—location, driving habits, even your phone contacts—and share it with automakers, insurers, and third parties. This guide shows you how to limit that sharing through your car’s privacy settings, giving you more control over who sees your personal information. You’ll learn where to find the settings, what each option does, and how to make the right choices for your privacy.

What You’ll Need

• Access to your car (or the automaker’s mobile app)
• Your car’s owner’s manual or quick reference guide
• An account login for the automaker’s app or website (if applicable)
• 10–15 minutes of time to go through the settings

Step-by-Step

1. Identify your car’s data-sharing features. Check your owner’s manual or the infotainment system’s menu for terms like “Data Sharing,” “Privacy,” “Connected Services,” “Telematics,” or “Vehicle Data.” Common features include: connected navigation, remote start/status via app, roadside assistance, and vehicle health reports.
2. Start with the infotainment screen. Turn on your car and go to the main settings menu. Look for a submenu labeled “Privacy,” “Data,” or “System.” The exact location varies by make and model, but it’s usually under “Settings” or “General.”
3. Review each data-sharing toggle. You’ll typically see options like:
   • Share location data: Used for navigation, stolen vehicle recovery, and traffic updates.
   • Share driving behavior: Used for usage-based insurance, fleet management, or driver scoring.
   • Share vehicle health/telemetry: Used for diagnostics and maintenance alerts.
   • Share voice recordings: If you use voice commands, these may be recorded and analyzed.
   • Share personal data (contacts, calendar): If you sync your phone, this data may be uploaded.

   Turn off any toggle you’re not comfortable with. If you’re unsure, start by disabling everything and only re-enable what you truly need.

4. Adjust the settings in the automaker’s mobile app. Many cars sync with an app (e.g., FordPass, MyChevrolet, Tesla app). Open the app, go to “Settings” or “Privacy,” and find similar toggles. Changes made here often override or mirror the car’s settings.
5. Disable “connected services” if you want maximum privacy. This cuts off most data transmission, but you’ll lose remote start, live traffic, and over-the-air updates. You can usually find this in the same privacy menu, or by contacting the automaker’s customer support.
6. Opt out of data sharing with third parties. Some automakers share data with insurance companies, data brokers, or marketing firms. Look for a separate opt-out option, often labeled “Share with partners” or “Data for analytics.” If you can’t find it, call the automaker’s privacy line and request a full opt-out.
7. Check your owner’s manual for a “privacy mode” or “valet mode.” Some cars have a setting that stops all data collection while the car is parked or driven by someone else. Enable this if you’re lending your car or are concerned about surveillance.
8. Review your privacy settings periodically. Automakers may update their software and reset your preferences. Set a reminder to check every few months, especially after a software update.

Common Mistakes

• Assuming the car’s settings are the only place to change things. The app and website often have separate toggles. You must check all three.
• Turning off everything and then wondering why your navigation doesn’t work. Real-time traffic and location-based services require location data. If you need those features, you’ll have to leave location sharing on.
• Not reading the privacy policy. Automakers often bury the opt-out in a long document. Look for a summary or “privacy choices” page on their website.
• Forgetting about voice assistants. If you use voice commands, your recordings may be sent to the cloud for processing. Disable voice assistant features if you’re concerned.
• Assuming “anonymous” data can’t be tied to you. Even if the car doesn’t send your name, your VIN, address, and driving patterns can be linked back to you. Treat all data as personally identifiable.

Tips

• Use a “guest” profile for valet or rental. Many cars allow multiple driver profiles. Use a guest profile when someone else drives, and that data won’t be saved to your profile.
• Disable “syncing” of your phone contacts and calendar. This prevents your personal data from being uploaded to the car’s system.
• Contact the automaker’s privacy office directly. They can provide a list of all data collected and how to opt out of each category. This is often more thorough than the in-car menu.
• Consider a privacy filter for your infotainment screen. This prevents passengers from seeing your personal data, but doesn’t affect data sharing.
• Keep a record of your settings. Take a photo of your privacy settings screen so you can compare if they change after a software update.

Troubleshooting

• I can’t find the privacy settings menu. Try the “Settings” gear icon, then “System,” “General,” or “Privacy.” If you still can’t find it, search your owner’s manual for “privacy” or “data.” Some automakers hide it under “Connected Services” or “Telematics.”
• I turned off data sharing, but the car still sends data. Check the app and website—they may have separate toggles. Also, some features like emergency SOS (eCall) are mandatory and cannot be turned off. That’s a legal requirement in many regions.
• My car’s settings reset after a software update. This is common. Revisit your privacy settings after every update. If it keeps happening, contact the automaker and ask them to preserve your preferences.
• I opted out, but I’m still receiving targeted ads. The opt-out may not be immediate (up to 30 days). Also, your data may have been sold to a data broker before you opted out—you’d need to contact the broker directly to remove it.
• The app won’t let me turn off a specific toggle. Some features are bundled. For example, you can’t have remote start without location sharing. You’ll need to choose between the feature and the privacy.

Frequently Asked Questions

Can I completely stop my car from collecting data?

No. Some data collection is mandatory for safety and legal reasons, such as the eCall emergency system. However, you can turn off most non-essential data sharing through the settings described above.

Does turning off data sharing affect my car’s warranty?

No. Automakers cannot void your warranty for disabling data sharing. Your warranty is tied to maintenance and repairs, not telematics. If a dealer claims otherwise, that’s a violation of consumer protection laws.

Will my car still get over-the-air updates if I disable data sharing?

No. Over-the-air updates require a data connection. You’ll have to re-enable data sharing temporarily to receive updates, or visit a dealer for manual updates.

How do I know what data my car is actually sharing?

Check your owner’s manual or the automaker’s privacy policy. Many automakers provide a “data transparency” page on their website where you can see a list of data categories and opt-out options.

Is my driving data being sold to insurance companies?

Some automakers share driving behavior data with insurers if you’ve opted into a usage-based insurance program. If you haven’t opted in, check your privacy settings to ensure “driving behavior” sharing is off.

Can I delete data that’s already been collected?

In many cases, yes. Contact the automaker’s privacy office and request deletion of your data. They are required to comply in many jurisdictions, though it may take a few weeks.
