Update 2025.26 - Release Notes

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.

If an unattended child is detected, the vehicle will flash the exterior indicator lights, play an alert tone, and send a notification to your Tesla app. This will repeat at regular intervals until you return to your vehicle. Cabin data is processed locally and is not transmitted to Tesla.

This feature is enabled by default. To disable, go to Controls > Safety > Child Left Alone Detection.

Experience light and sound in perfect harmony. Accent lights now respond to your music, adjusting in real time to both sound and surroundings to deliver a consistent visual impact across genres and lighting conditions.

For an even more immersive experience, you can also match the lights to the album's art color. While parked, turn on Rave Cave to transform the cabin into your own personal nightclub - with maximum brightness and full-on party vibes.

Go to App Launcher > Toybox > Light Sync.

The Dashcam app now lets you adjust playback speed for more flexible viewing. You can also choose whether the video fills the screen or keeps its original size.

While parked, go to App Launcher > Dashcam.

To improve the site arrival experience, new icons in the charger list now indicate locations that require valet service or pay-to-park access. Upon arrival, a notification provides key details such as access codes, parking restrictions, level or floor information, and restroom availability. This information is also available on the site card.

Customize your sound with personal equalizer presets. You can create and save multiple presets to match your listening preferences. Audio settings are now located under Controls > Audio and can also be found using the Controls search.

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 with the steering wheel, among other functions.

Go to Controls > Service > Onboarding Guide.

Tesla has added a new locking animation when you remotely lock your vehicle through the Tesla app or by walking away, and there’s still someone in the vehicle with a phone.

This new alert lets users inside the vehicle know that the vehicle can still be opened from the outside due to a phone key being nearby.

Tesla’s mobile access option, found under Controls > Safety, can safely disable your vehicle from being controlled from Tesla’s mobile app. This removes the ability to control any aspects of the vehicle, including seeing the location, unlocking and starting the vehicle.

To disable mobile access, you previously had to provide the email associated with your Tesla account. You can now provide the email address or the phone number associated with your Tesla account.

Tesla has removed its Battery Health Test feature from many, but not all, vehicles. Tesla’s Battery Health Test was initially added to Service Mode, but was later added to the vehicle’s main menus under Service — allowing more users to access it.

The test allows owners to see their vehicle’s battery degradation levels. While the tool under Controls and Service Mode are almost identical, the main menu version requires your vehicle to have less than a 20% state of charge before performing the test. It also only allows you to run the test once every six months to prevent further degradation from running the test too often.

It’s not clear why the feature has been removed at this time, even for vehicles that have never run the test, but the removal depends on your vehicle’s model, age, and potentially other factors.

In the latest software update, 2025.26, Tesla has added another new, undocumented feature that helps to improve the Cybertruck’s utility. When towing heavy objects, you need to be sure you balance the trailer and stay within the weight limits of the vehicle. Now, your Cybertruck can detect and warn you if the vehicle’s load rating is being exceeded.

Car Wash Mode has been improved with this update. While Car Wash Mode will still close windows when it’s initially activated, it will now also continuously monitor your vehicle’s windows and warn you if any windows are opened during the car wash.

New Vehicle Functions Panel (Service Mode Plus)

A new Vehicle Functions panel with an overview of all vehicle functions, their limitations, and respective states (no conditions detected, degraded, or unavailable) is available. The panel enables users to understand the impact of conditions on affected vehicle functions and pinpoint the respective underlying alerts.

Note: This feature was added in update 2026.26.3 and is not available in prior 2025.26 updates.

Make sure to maintain vehicle power and monitor the pressure in the Refrigerant panel while running the Drain and Fill routine.
