Tesla has recently started rolling out update 2025.20, which means that most vehicles should now have received the 2025.14 update. While this Spring Update wasn’t as big as the 2024 update, it added several exciting features, such as Adaptive Headlights and Avoid Highways.

In addition, it also features 10 new features that didn’t appear in Tesla’s release notes. Join us as we go through all the smaller additions.

Improvements to Heated Steering Wheel

If the steering wheel heater is set to Auto, the steering wheel will now heat up based on the cabin temperature, even if the climate system is set manually.

Previously, the climate system needed to be set to Auto for the steering wheel heater to turn on automatically.

Apple Music Improvements

There have been several improvements to Apple Music. Besides shuffling an entire Apple Music playlist instead of just the first 100 songs, Tesla has also improved these other options:

- If you’re listening to one of Apple Music’s curated stations, such as Apple Music 1, the name of the song and artist will now be displayed in the music player instead of the name of the station.

- The latest Apple Music stations, including Apple Música Uno, Apple Music Club, and Apple Music Chill, are now selectable in your Tesla.

Language Support

While other Tesla models support a variety of languages, the Cybertruck was limited to English. With this update, you can now switch the on-screen language, the voice recognition language and navigation language to options available in other Tesla models.

Note: Navigation languages are limited by your map region.

Sentry Mode Improvement

Sentry Mode automatically turns off if the vehicle’s battery falls below a 20% state of charge. However, with this update, Sentry Mode will now automatically come back on if the vehicle is plugged in.

Lane Departure Avoidance Updated to FSD

Not a Tesla App

Tesla appears to be migrating core safety features from the legacy Autopilot stack to the newer FSD stack. Update 2025.14 added Lane Departure Avoidance (LDA) and Lane Assist to the Cybertruck—despite it not supporting Basic Autopilot, which these features were previously based on.

Instead, these features now appear to be based on FSD, which not only means that the Cybertruck can include them but that they’re also based on a newer and much better tech architecture that better understands the environment.

The visualizations have also been changed for these two safety features. Previously, when these features were activated, the visualizations would revert back to Autopilot.

Now, the visualization for LDA will feature a blue line on both sides of the lane marking you’re going over. These changes appear to only affect vehicles with FSD in North America for now. However, they apply to HW3 and HW4 vehicles.

We also wrote a more in-depth look at the updated Lane Departure Avoidance feature.

Improved Dashcam Viewer

Although vehicles with HW3 are not receiving the B-pillar camera recording for Sentry Mode and Dashcam, they are receiving the improved Dashcam Viewer if they include the AMD Ryzen infotainment chip.

The updated Dashcam Viewer has several new features, including a new grid view that lets you view four cameras at once, making it easier to view what happened during the event.

The updated player now also includes buttons to jump back or forward in 15-second increments, as well as the ability to jump directly to the next clip.

The different camera views are now placed along the bottom instead of at each corner of the video.

Camera App

Not a Tesla App

For HW4 vehicles (how to tell), the Camera app has been updated so that the repeater cameras are now displayed at the top instead of the bottom. Each camera feed is also labeled so that users can more easily identify the rear, left, and right cameras.

In addition, the field of view for the rear camera is now wider, not only in the vehicle but also when viewing the rear camera through the Tesla app.

In update 2025.20, Tesla is adding another change that will now let you switch between the wider and narrower views.

Speedometer

Not a Tesla App

In regions where km/h is used, Tesla has updated the speedometer to properly reflect km/h instead of KM/H.

Sentry Mode Menu

Not a Tesla App

The Sentry Mode menu has been updated to make it easier to turn on Sentry Mode for a one-time use.

Under Controls > Safety, Tesla now has separate controls to turn on and off Sentry Mode one time (the button with the Sentry Mode icon) and the option to enable Sentry Mode whenever the vehicle is parked.

The exclude home, work and favorites options only show up when you enable Sentry Mode when parked.

World’s Largest Tesla Supercharger: 168 Stalls, 100% Off-Grid, Powered by Sun and Battery Storage

By Karan Singh

In just 8 months, Tesla has gone from breaking ground to delivering electrons at its most ambitious Supercharger project to date, just in time to be ready for the busy Fourth of July holiday weekend. Project Oasis, the world’s largest Supercharger site, is now partially open to customers for its first phase in Lost Hills, California.

What makes this remarkable is the speed of execution. In just eight months, Tesla has constructed a site that will eventually feature 168 stalls (84 stalls are now open), supported by 11 MW of solar power and 10 Megapacks of battery storage. That construction speed is pretty impressive, but what is even more impressive is how this new station operates and what it means for future Supercharging infrastructure.

Self-Sufficient Energy Oasis

Not a Tesla App

The first 84 stalls at Lost Hills are now open, and according to the Tesla Charging team, they are currently powered solely by the sun and operate off-grid.

This makes it more than just a new Supercharger site. It serves as a proof of concept for a new type of Supercharger. Unlike nearly every other charging site in the world, which draws power from local utilities, this station generates its own clean electricity from its massive solar array and stores it in its array of on-site Megapacks. 

Self-sufficient charging stations are something completely different than what we see today. They are highly resilient since they’re not reliant on the grid. That means that even if there is a local power outage, brownout, or blackout, one can always come to Lost Hills to Supercharge.

If you’ve got a Cybertruck, you could take advantage of the Cybertruck’s Powershare feature and charge up at Lost Hills to help keep your home powered during a blackout, utilizing the Cybertruck as a portable battery charger. Now that’s true independence and self-reliance.

The Future of Charging

Solar-powered Superchargers help avoid massive new loads on already stressed electrical grids, especially during peak afternoon and evening hours, when demand is the highest.

This is Tesla’s vision for the future of charging: a clean, fully closed-loop ecosystem that sustains itself. The sun’s energy is captured, stored, and delivered directly to vehicles on site at any time of day without relying on the electrical grid or fossil fuels.

Largest Supercharger in the World

This opening of 84 stalls is just the first phase of the project. Tesla says that the remaining stalls, as well as a new on-site lounge, are coming later this year. Once complete, the 168-stall site will be the largest Supercharger site in the world.

While the speed of building such a massive project in just eight months is a testament to Tesla’s execution, the true innovation is actually that self-sustainability. Let’s hope we see even more large, self-sufficient Supercharger sites across the world in the near future.

Elon Musk Considers Solar Gigafactory in North America to Power AI Boom

By Karan Singh

Elon Musk is once again seeking to expand Tesla’s vertical integration in the energy sector, this time focusing squarely on solar power. Following discussions on X that highlighted the massive gap in solar deployments between the US and China, Elon is now discussing the need for a Tesla Solar Gigafactory in the United States.

This potential move is driven by a specific catalyst: the exponential growth of AI is creating an insatiable demand for electricity. For Tesla and xAI, two of Elon’s companies betting their future on AI, building the power generation required is a strategic necessity.

A new factory wouldn’t just be about making panels; it would be about manufacturing the final missing piece in Tesla’s vertically integrated energy ecosystem.

Catching Up to China

The context for this renewed focus is pretty stark. In May, China reportedly added a staggering 93 gigawatts (GW) of solar power capacity. In contrast, the United States installed approximately 14 GW over the entire first quarter, roughly 20 times less than China.

The primary driver of this demand is the revolution in AI. Training ever-larger and smarter AI models involves operating vast data centers, which consume staggering amounts of power. Google, Amazon, and Microsoft have turned to small-scale nuclear reactors, with Microsoft petitioning to reopen the infamous Three Mile Island for its AI operations.

For Elon’s companies, whose future products like FSD, Optimus, and Grok are built on a foundation of real-world AI, securing a massive and sustainable energy supply isn’t a side quest. It is part of the main mission, especially in conjunction with grid-scale storage, such as Megapacks and Powerwalls. You can’t power a world of autonomous robots without a world of abundant, clean energy.

The Tesla Ecosystem

A US solar gigafactory would be the final, logical step in completing Tesla’s energy hardware ecosystem. While Tesla already manufactures some solar panels and the Tesla solar roof, the scale is too minuscule to matter. 

By mass-producing its own panels, while also increasing Solar Roof production, Tesla would become a true one-stop shop for all things green energy. This would allow the company to supply its own large-scale projects, like the massive solar array for Project Oasis - the world’s largest Supercharger site.

It would also enable more complete residential packages, like the Giga-Small Haus concept home, combining Tesla-made panels and roofs with a Powerwall 3. This level of vertical integration would give Tesla complete control over the technology, cost, and supply of every major component in its energy ecosystem, from generation to storage to mobility.

Building a new Solar Gigafactory is about much more than just simply producing solar panels. It’s a requirement to power Tesla’s future products and make solar panels accessible to everyone.
