Every Tesla update includes smaller, undocumented changes. While the 2026.20 update was no Summer Update in terms of features, it did include up to 24 hours of Dashcam footage if you have a large enough USB drive. It also included Dashcam encryption for privacy, improved parental controls to lock out certain apps, and introduced Hey, Grok in additional regions.
Here is the list of undocumented features that didn’t make it into Tesla’s official release notes.
License Plate Frame
With Tesla’s recent addition of license plate customization, they also added a shortcut for it under Controls > Software, similar to the Colorizer/Wrap feature.
Tell Whether FSD is Enabled in App
With this update, Tesla tweaked the icon slightly by adding a license plate frame around the license plate image. Tapping this icon takes you directly to the license plate customization feature like before.
Tesla will now display whether a vehicle has FSD enabled in the Tesla app. In addition, the app will now also display the blue FSD path and even the rainbow road easter egg if it’s enabled in the vehicle.
This requires Tesla app update 4.58.5 or higher and vehicle update 2026.20.6.1 or higher.
Decrypt Dashcam Video
In update 2026.20, Tesla started encrypting Dashcam footage. This came at the same time as Tesla expanded recent video footage from 1 hour to up to 24 hours under certain requirements.
Encrypting the videos is an important privacy change, since if your USB drive is pulled from your vehicle, thieves can now have access to up to 24 hours of your driving, potentially revealing your workplace, home, and other important locations.
With this update, Tesla also added a button to the Dashcam Viewer that lets owners easily decrypt a specific clip, making it easier to see the footage if they mount the USB drive to their computer.
Tesla also introduced a tool that lets you decrypt any videos on your computer, as long as you log in to your Tesla account to prove that you own the video footage.
Bus Lanes
Tesla’s navigation now supports bus lanes, helping drivers be more aware of which lanes they can use.
This is even more important for FSD, so the vehicle can know which lanes are appropriate to drive in without having to read or potentially miss signs.
Service Mode Improvements
A new Forward Camera View Cleaning panel is available under Driver Assist to support cleaning the surface of the windshield in front of the cameras. The panel displays a live camera stream with the ability to zoom into the camera stream.
Models: Model 3, Model Y, Model S (2021+), Model X (2021+) with DAS AI4 and Cybertruck
The Drive Unit panel now supports interactive signal chart popups. Signals with a chart icon can be tapped to open a draggable, resizable popup window for real-time signal monitoring.
Models: Model 3, Model Y, Model S (2021+), Model X (2021+), Cybertruck
