Selling a connected car? Wipe more than the glovebox

Why deleting a phone pairing is not enough

An infotainment system can retain contacts, messages, call history, destinations, home and work addresses, Wi-Fi credentials, media accounts, and paired-device identifiers. The vehicle may also remain attached to a manufacturer's account that controls remote unlock, location, charging, subscriptions, or driver profiles.

A separate garage-door opener, toll transponder, dashcam memory card, insurance telematics device, or aftermarket head unit can hold additional access or history.

How to delete data from a car

Selling a connected vehicle requires a transfer checklist. Complete these steps before the vehicle leaves your control, then confirm that the buyer cannot see the car in your account.

• Remove every driver profile, paired phone, contact list, destination, Wi-Fi network, and voice history available in the vehicle menus.
• Sign out of music, maps, charging, parking, tolling, and other embedded apps.
• Erase dashcam and event-recorder media you own; do not destroy records subject to a legal or insurance hold.
• Clear garage-door and gate codes and revoke shared digital keys.
• Factory-reset the infotainment system using the owner's manual procedure.
• Remove or transfer the VIN in the manufacturer's app and connected-services account; cancel subscriptions and insurance tracking programs.
• Keep confirmation of the transfer or account removal.

If you bought the car used

Reset it again, check for unknown profiles and Bluetooth devices, inspect the diagnostic port for third-party trackers, and establish yourself as the account owner through the manufacturer's documented process. Contact the manufacturer if a previous owner still controls remote functions.
