Tesla’s latest update includes a special feature for Cybertruck that may eventually be rolled out to the rest of the lineup. It appears Tesla is getting ready for the summer road trip season early by focusing on enhanced security for drivers who tow trailers and improving accessibility to its Supercharger network for such vehicles.

Cybertruck's New Trailer Alarm Feature

With update 2024.8.4 Tesla is introducing a trailer alarm system for the Cybertruck. This innovative feature extends the vehicle's alarm system to monitor the connection status of a trailer hitched to the vehicle. In practical terms, this means the vehicle's alarm will now also protect the trailer, ensuring an added layer of security for owners' valuable cargo.

Activating or deactivating alongside the vehicle's alarm system, this feature can be conveniently managed through the vehicle's settings under the "Towing and Hauling" section, where the "Trailer Alarm" option is located. Owners who prefer not to use this feature can disable it, tailoring the vehicle's security settings to their preferences. At this point, we only have confirmation of the feature in Cybertruck, but it would make sense to add it to the other models that haul trailers as well.

The release notes state:

“Your vehicle alarm now also monitors whether your trailer is plugged in to the hitch.

The trailer alarm sets and turns off along with your vehicle alarm. You can disable this security feature in your vehicle settings at Towing and Hauling > Trailer Alarm.”

Tesla Will Show Which Superchargers Include Trailer-Friendly Stalls

Tesla is also improving the Supercharging experience for drivers with trailers. Recognizing owners' difficulties when charging vehicles while towing, Tesla has been progressively introducing pull-through stalls at Supercharger stations. These stalls are designed to accommodate vehicles with trailers, eliminating the need to detach trailers before charging – a significant improvement over the traditional back-in stalls that dominate the network.

Wes Morrill, a Cybertruck engineer who has become more vocal on X, posted that the “Supercharger team is always looking for opportunities to install these at new locations. Will show trailer friendly stalls on the in-vehicle UI to make it easier when road tripping with a trailer.”

Once this feature is implemented, we expect Tesla to list the number of pull-through stalls next to the number of available stalls at each Supercharger location. Tesla already displays how many stalls are in use, how many cars are en route to the Supercharger, and if any stalls are out of order, as determined by their monitoring service.

Amid rising gas prices, Tesla's updates offer a cost-effective solution for summer road trips. The new trailer alarm and UI improvements for finding Supercharger stations address towing challenges, enhancing the Tesla experience. This initiative showcases Tesla's commitment to innovation and sustainable travel, enabling owners to bypass the impact of fuel costs and enjoy their adventures.

Tesla Software Update 2025.26: Grok, Light Sync, Audio Presets and More [VIDEO]

By Not a Tesla App Staff

Tesla has officially announced the next major software update, 2025.26. As expected, this update will introduce the Grok AI assistant to Tesla vehicles, although it’ll initially be limited to the U.S.

Tesla also announced several other features that will arrive in update 2025.26, such as Light Sync, the ability to create and save audio presets, and others.

We’ll break down each new feature and which models and regions we expect it to be available in.

Grok

Not a Tesla App

After the Grok UI was revealed in update 2025.20 and the Tesla app included the ability to log in to Grok, it’s not surprising that Tesla has finally unveiled Grok in Teslas.

As expected, Grok will only be available on AMD Ryzen-based vehicles. Tesla says that it will also be limited to the United States and require Premium Connectivity, but it looks like it won’t require a subscription to anything else, such as Super Grok.

Unfortunately, Tesla announced that Grok will not be able to control elements in your vehicle and that the old voice command system will still be used to do that.

In a post on X, Tesla showed off Grok in action for the first time, showing the interaction between the driver and Grok. The Grok interface displays sound waves in rainbow-like colors when it’s speaking, much like another popular device. Tesla’s video of Grok is below:

Supported vehicles: Based on Tesla’s post, this is expected to include all AMD vehicles, including the Model S, X, 3, Y, and Cybertruck.

Supported regions: U.S.

Light Sync

Not a Tesla App

Tesla continues to improve the ambient light feature in Teslas by integrating it into more things. Tesla recently started using the ambient lights during Santa Mode and Rainbow Road. They also turn the ambient lighting red when you’re in Service Mode. However, this time, they’re going one step further. The ambient lights can now react to the music you’re playing by presumably changing colors based on the beat.

You’ll also have the option to maximize the brightness of the ambient lights when this feature is enabled, but only when the vehicle is parked, which Tesla is calling Rave Cave.

In addition to reacting to the music, the lights can change color to match the album color of the music being played, which is kind of similar to the ambient lights on some TVs matching the content being displayed. A needless addition? Sure. But very cool as well.

Tesla shows a screenshot of this feature, which is included in the Toybox app, and shows that you can enable or disable each feature individually, including syncing the lights to music, max brightness, and matching the album artwork color.

Supported vehicles: All vehicles with the ambient lighting feature, including the Cybertruck.

Supported regions: Assumed to be available everywhere.

Audio Settings Update

Not a Tesla App

Another feature Tesla highlights is the ability to create presets for audio settings. These audio settings will be in a new Audio tab in the vehicle’s settings, and they’ll allow you to create and save presets for different types of music. For example, you can have a preset for spoken content and another one for pop music.

Each preset will let you adjust the equalizer and set the immersive sound level.

What’s nice here is that it seems that Tesla has redesigned the audio settings and moved them to the main vehicle controls instead of only having them accessible through a button in the music player. You can see the Balance tab at the top, although it doesn’t look like you’ll be able to save the balance as part of the preset.

Supported vehicles: This is expected to be available on all vehicles, although it could exclude the legacy Model S/X.

Dashcam Viewer Updates

Not a Tesla App

This Dashcam Viewer update is only for AMD-based vehicles. It includes the ability to change the playback speed of the video being played, a feature of the old Dashcam Viewer which was surprisingly not included in the new player.

The playback speed is shown on the screen, and you’ll be able to tap it to cycle between varying speeds. The older Dashcam Viewer lets you choose between 0.5x, 1x, 1.5x, and 2x playback speeds, and this is expected to be the same in this update.

With this update, the new Dashcam Viewer also arrives on the Cybertruck for the first time, which was the only Ryzen vehicle excluded when the update was originally released.

Supported vehicles: All AMD Ryzen-based vehicles.

Supported regions: Assumed to be available everywhere.

Supercharger Improvements

Not a Tesla App

As we talked about in an earlier article, Tesla is adding more information to the Supercharger list in your vehicle. Tesla will now show which Superchargers require paid parking, valet, or an access code.

This isn’t as exciting a feature, but it surely prevents a lot of unnecessary frustration for users who arrive at a Supercharger location only to find out it requires you to pay for parking, is only available for valet service, or has other requirements.

If the Supercharger is in a garage, Tesla will now include the floor or level number that the Supercharger is on. While there are usually physical signs at these locations, knowing the floor number the charger is on ahead of time will definitely make it easier to find.

Supported vehicles: Expected to be available on all vehicles.

Supported regions: It’s not clear whether this will be available in all regions.

Onboarding Guide

Not a Tesla App

The last feature that Tesla is highlighting in update 2025.26 is a new onboarding guide that will help new owners become familiar with their vehicles.

According to Tesla, the new guide will run through several features, such as adjusting your seat and mirrors, as well as controlling certain vehicle functions, including the lights, wipers, and Autopilot. This will be a great addition for new owners, as accessing some of these features isn’t apparent, especially if they require use of the unlabeled scroll wheel, such as activating Autopilot on newer vehicles without a stalk.

Supported vehicles: This is expected to only be available on AMD Ryzen vehicles, but Tesla doesn’t specify which vehicles it’ll be available on. Once the update starts rolling out, we should have more information.

Supported regions: This will likely be available in all or most regions.

Release Date

There may be other features included in update 2025.26 that Tesla isn’t highlighting in their post. Tesla often doesn’t include smaller additions or features that were previously introduced but have now been added to more regions.

There’s no doubt that the biggest feature in this update is Grok, but the other updates are nice improvements as well. This feature is expected to roll out to employees this weekend, and it should start rolling out to customers in the next week or two.

Tesla’s Robotaxi Expansion: Tesla Applies in Arizona and Creates Job Postings

By Karan Singh
Not a Tesla App

Tesla is moving to aggressively expand its Robotaxi Network at a rapid pace, with new information revealing that an expansion into Arizona is imminent, pending, of course, regulatory approval. Tesla has already begun looking at building out the program to other cities, just weeks after the launch of its pilot program in Austin, Texas.

Phoenix, Arizona, is Next

In a letter received following a query submitted by Sawyer Merritt, the Arizona Department of Transportation (AZDOT) has confirmed that Tesla had officially applied for Robotaxi permits on June 26th, 2025. According to AZDOT, Tesla had applied for the permits for both autonomous vehicle testing and operation with and without a safety driver.

The department also confirmed that Tesla has expressed its interest specifically in operating within the Phoenix Metro area, with a decision on the permits expected by the end of July. This is the first official step to establish Robotaxi within a second state, which is exciting to see.

Tesla Hiring Vehicle Operators

The move into Arizona isn’t an isolated event. It’s the first step in a broader national expansion, as per Tesla’s recent job postings for Robotaxi Vehicle Operators and FSD testers on Tesla’s Careers page. 

These positions, which are necessary for Tesla to launch and validate the service in new locations, show us where Tesla plans to deploy Robotaxi next. The areas include:

  • Tempe, Arizona

  • Palo Alto, California

  • Fremont, California

  • San Diego, California

  • Henderson, Nevada

  • Jacksonville, Florida

Tesla is simultaneously laying the groundwork for expansion in at least three other states besides Texas and Arizona, and that’s a good sign for the network’s quick expansion. Tesla’s executive cadre pointed to a timeline of late 2025 for Robotaxi to be deployed in multiple cities across the United States, and it appears that this timeline is on track.

The Scalability Advantage

This strategy of pursuing multiple markets in parallel highlights the advantage of Tesla’s generalized autonomy approach. Because FSD is designed to be a generalized solution that learns from a global fleet, Tesla does not need to spend years meticulously pre-mapping every street in a new city. 

Instead, it can target new locations and use a smaller fleet of operators to validate the performance and safety of FSD within a new environment. After all, every city has its own unique traffic regulations and environmental considerations that need to be understood.

The key here is that Tesla can turn on a fleet in a whole new location in just a fraction of the time required by other methods, such as HD mapping - which can require hundreds of mapping vehicles, thousands of hours of real humans driving, and many hours of engineering to get all the data cleaned up and ready for use.

The Austin pilot is just the beginning of Robotaxi. Tesla is already planning to expand the geofence this weekend and plans to scale the network to other cities soon.
