Vehicle Offline / Missing Data

If data is missing or the vehicle is offline, it means Tesla or Tessie isn't able to contact the vehicle.

How can I fix it?

After analyzing years of data across the Tesla fleet and comparing diagnosis notes with Tesla Service Centers and engineers, we've found that this can also be caused by the following:

Weak cellular or WiFi signal (change to cellular or WiFi)
Hotspot tethering (change to cellular or standard WiFi)
Low or defective 12V battery (replace it)
Defective connectivity board (replace it)
Firmware versions prior to 2023.44.30.7 (upgrade firmware and the MCU, if necessary)
Modem and SIM card changes may cause issues

When in doubt, try an easy fix by restarting the vehicle.

Looking for old data?

Tesla vehicles do not store historical data, so it's not possible to retrieve drives or charges from before activating Tessie.

If you're needing to restart frequently

If tracking or connectivity are dropping out frequently and requiring regular restarts, it's highly indicative that Tesla may need to replace the 12V battery or the connectivity board.

(Legacy Model S/X) If the start of a drive or charge is missing

Enabling Sentry Mode will prevent missing data.

For pre-2021 Model S/X vehicles, Tessie stops data retrieval when the vehicle becomes idle to allow it to go to sleep. This time window is 20 minutes. If the vehicle doesn't sleep, and driving or charging begins, the start of the drive or charge may be missed.

Tesla is working on an improved tracking solution for these vehicles for late 2024.
