Update 2025.38.3.1 - Release Notes

Greetings Programs. Transform your vehicle into the Light Cycle.

Go to App Launcher > Toybox > Tron.

You can now see buildings and cityscapes in more detail with 3D view. To enable, switch to Map View and tap the 3D icon.

Requires Premium Connectivity.

You can now switch to satellite view by tapping the globe icon on the map.

Street names are now included in dashcam event details (when available), making it easier to distinguish between recorded events. In addition, the Mobile Dashcam Viewer now streams and downloads at a higher resolution. Requires Tesla App version 4.49.5+.

Editorial note: Legacy Model S and Model X receive the street name details in Dashcam events, but it does not include the Mobile Dashcam Viewer.

Your vehicle's side cameras (B-Pillar) will now be recorded to both Dashcam and Sentry clips.

Your left scroll wheel includes new options for quickly accessing various vehicle controls, such as Bioweapon Defense Mode, Mute Navigation, and Music Light Sync - if available in your vehicle.

Press and hold the left scroll wheel to open the menu.

You can now talk to Grok, an intelligent assistant built by xAI. Choose Grok's voice and personality, ranging from Storyteller to Unhinged. To launch, go to the App Launcher > Grok, or long-press the voice button on your steering wheel.

Requires Premium Connectivity or a Wi-Fi connection. Conversations are anonymous to Tesla and not associated with your vehicle.

Note: Grok is currently in Beta and does not issue commands to your car - existing voice commands remain unchanged.

The Onboarding Guide helps you get familiar with your Tesla. It covers adjusting driver settings, using the touchscreen as well as controlling lights, wipers, and Autopilot features - among other functions.

Go to App launcher > Manual > Get To Know Your Tesla.

- Street names are now included in dashcam event details (when available), making it easier to distinguish between recorded events.

- Apple Music provides an organized playlist view with folders, expanded artist pages and a Recently Played shelf that displays more of your listening history.

- You can log in to your media using a Tesla app notification for a faster, more seamless experience. (Not available for legacy Model S and Model X)

- You can now choose whether a phone key is required before a driver profile can be selected. Go to Driver Profile Settings > Require Phone Key for Profile. (Not available for legacy Model S and Model X)

- This update includes important security fixes and improvements.

Tesla has added Santa Mode to 2026 Model S and Model X vehicles. These cars use the Unreal Engine and did not include Santa Mode until this update. Santa Mode was noticeably absent from the Toybox, and when users tried to enable the feature through voice commands, the system would say that Santa Mode is not available and will be enabled in a future update.

When a user activates FSD from the Controls > Autopilot menu, Tesla will now present a one-screen guide that introduces the user to FSD.

The guide includes the same disclaimer as previous updates and now also includes an image of the steering wheel controls for FSD, letting the user know how to switch FSD Profiles and set the maximum speed (for FSD V13 and below).

The image used is specific to the vehicle and will either include steering wheel buttons or stalks, depending on the model.

While a vehicle is charging, Tesla now includes a link for ‘Additional Charging Information’ in the Controls > Charging section. If the vehicle is charging, the link will appear in blue in the top-right corner.

Tapping the link displays a pop-up containing additional information, such as the maximum and current battery input power.

Maximum Battery Input Power is the total power the charger can deliver.

Battery Input Power is the amount of energy that is being actively put into the vehicle’s battery. The battery input power may be less than the maximum charger capability for several reasons, including a high vehicle charge level. The vehicle will also draw power directly from the charger rather than draining the battery if it needs to run the HVAC system, screen, or other components. This reduces battery wear by using energy from the battery, only to have to re-add it.

The 2025.38 vehicle update adds support for the ‘Keep Accessory Power On’ option in the latest Tesla app. This option is part of the latest Tesla app update, which adds the new Charging menu that consolidates most charging options under a single menu.

It also adds a button for Low Power Mode, instead of just being under Quick Actions.

Tesla has added a Buy Parts button to Tesla’s Service Mode. Tapping the button displays a QR code that takes users to Tesla’s service site, where owners can buy parts directly from Tesla.

Parts can be shipped directly to the customer or to the nearest service center.

Tesla has added a visualization of a charger when the vehicle is parked and plugged in. In this photo, the owner is using a non-Tesla charger, so a generic charger is displayed. Tesla will presumably display a mobile charger, Wall Connector, or Supercharger if those are plugged into the vehicle.
