Tesla owners who are dog lovers no longer have to decide between Sentry Mode and Dog Mode. That is just one of several enhancements in the latest update — 2022.40.1.
Other improvements include battery preconditioning, driver door unlock and radio station logos, while existing features have launched in new regions.
New Features
Let's start with the Sentry and Dog Mode combo. Both of these features would rate high on items that Tesla owners appreciate about their vehicles. Sentry is a best-in-class security/surveillance system, and Dog Mode keeps the cabin at an appropriate temperature for your pet while you are away.
However, the two systems did not work together because Sentry would constantly be triggered whenever the dog moved inside the vehicle. For those who have dogs that love car rides, this meant not being able to use Sentry to protect your car and your dog. Now both features can be used together for most vehicles. This update silences Sentry Mode alarms while still recording and keeping the temperature safe for your pooch.
Listening to the radio may get more appealing with the addition of radio station logos to the media player.
The radio in a Tesla doesn't get a lot of recognition since competes against music streaming services and other entertainment that have much more engaging screens, but Tesla did a great job with its radio implementation.
The radio will automatically scan for local stations, so you can just tap to get to your favorite station. It also offers a direct input instead of a radio dial and now features radio station icons to make it easier to find your favorite station. With this update the list of radio stations has been changed to a grid to make room for the station name and logo. When playing an FM radio station, the station's logo will also appear in the album artwork area of the music player. (Photo credit to ArsalamiSandwich).

Voice directions are now available in Hebrew in the Middle East. Tesla continues to expand the languages offered in its vehicles. It's estimated that 9 million people speak Hebrew worldwide.
Improvements to Existing Features
In an effort to speed up charging times, the thermal system control will now be optimized to match the charging station's power capability. The company has been expanding its vast network of Superchargers, which means there are many variations in the station output. This update means your Tesla won't waste too much energy preparing the battery if you're headed to a slower DC charging station.
Update 2021.44 added the ability to only unlock the driver's door when the handle is pressed to improve safety. However, it wasn't ideal when traveling with passengers as they would have to wait until you get into the vehicle to open the other doors.
With update 2022.40, Tesla did what it does best — improve vehicle features. If you have the Driver Door Unlock Mode feature on, you can now hold and press the interior driver door switch to unlock all vehicle doors and trunk.
If this update Tesla is also adding this feature to the new Model S.
To access Driver Door Unlock Mode, tap Controls > Lock > Driver Door Unlock Mode.
More vehicles and regions now have access to a consistent regenerative braking feel even when it's limited. For example, regenerative braking may not be available when the battery is at a max charge or in certain weather conditions. In May 2022, Tesla sent out an update to many areas and vehicles, allowing the car to behave the same way when it is decelerating with or without regenerative braking. This feature enables drivers to perfect the one-foot driving technique at all times.
With this update, it is now available for some legacy Model S and Model X vehicles.
With winter coming, the Tire Configuration program is now for the Model Y as well. It allows users to reset the learned tire settings after a tire rotation or replacement for an improved driving experience. To reset, tap Controls > Service > Wheel & Tire Configuration > Tires.
Other changes include exterior lighting improvements and Sentry Mode Live Camera Access added to Israel, Supercharger details included in China, and Boombox is now available in Japan. However, Hong Kong went against the trend as it continues to allow fewer features. The dashcam viewer has been removed, the country recently took away Tesla's arcade and Toybox.
In a new video posted to X, Tesla is showing the progress of its first Lithium Iron Phosphate (LFP) cell manufacturing factory in North America. The facility, located in Sparks, Nevada, will be used to produce LFP battery cells for Megapacks and Powerwall.
However, the implications of this new factory extend beyond Tesla Energy. By on-shoring the production of these cost-effective batteries, Tesla is not only securing its energy supply chain but also opening the door to potentially reintroducing LFP-based vehicles in North America.

The immediate beneficiary of the new Nevada LFP facility is Tesla’s Energy division. LFP chemistry is ideal for stationary storage products like Megapack and Powerwall. It offers a very long life cycle, is extremely thermally stable and safe, and is significantly cheaper to produce than nickel-based batteries, partly because it contains no cobalt.
Until now, Tesla has relied on suppliers like CATL in China for these cells. A dedicated, domestic supply will enable Tesla to dramatically ramp up Megapack production to meet North America’s increasing demand for grid-scale energy. On the other hand, Megafactory Shanghai continues to utilize CATL’s LFP batteries and will support the rest of the world.
Tesla first revealed that they were planning to onshore LFP production in North America at the Q1 2025 Earnings Call, which will help them avoid costs, innovate in new technology, and insulate themselves from geopolitical supply chain risks.
A Potential Return for LFP Vehicles?
Another exciting application for Tesla is what this new factory means for Tesla’s budget-oriented lineup. For years, Tesla has been constrained in its ability to offer LFP-based vehicles in North America. While LFP packs are used in other markets for specific standard-range RWD vehicles, tariffs on important Chinese cells made it difficult to import these cells for use in North America.
With a domestic supply of LFP cells produced in Nevada, this tariff-related barrier will be mostly eliminated, pending the sourcing of lithium from a North American site. This is likely to lead to the reintroduction of LFP-based vehicles to the North American market, possibly in late 2026 or 2027.
An American-made LFP pack could lead to a more affordable base Model 3 or Model Y, or potentially help Tesla cut costs on the next-generation Affordable Model even further. This helps to give customers a lower-cost entry point without sacrificing a lot of range, and with the added benefit of being able to regularly charge to 100%.
Mega Nevada
With Mega Nevada now progressing well, Tesla is in an excellent position to continue iterating on its vertical integration and scaling Megapack and Powerwall—two of Tesla’s fastest-growing businesses—further. There are tons of benefits for consumers in the future as Tesla continues down this path, with more affordable Powerwalls for the home, cheaper electricity prices thanks to grid-forming Megapacks, and cheaper LFP vehicles.
The next major upgrade for Tesla’s in-car experience is pretty much already here - just hiding beneath the surface, awaiting the flick of a switch. According to new details uncovered by Tesla hacker Greentheonly, a fully functional version of the Grok conversational AI assistant is already present in recent firmware builds, just waiting for Tesla to activate it.
The feature, which is currently behind a server-side switch, could be enabled at any time by Tesla for vehicles running update 2025.20 and newer. The findings provide a better picture of what we already learned from Green’s breakdown on Grok last month.
Grok’s Requirements
@greentheonly on X
According to what Green determined from the latest software builds, the foundation for Grok was laid with update 2025.14, with more abilities and functionality added in 2025.20 to flesh it out. He also determined exactly which vehicles will be receiving Grok.
In terms of hardware, any vehicle with a Ryzen-based infotainment computer will receive Grok. This means that vehicles with the older Intel Atom processor will not be supported, at least initially. The underlying Autopilot hardware is not a factor, as Grok’s processing is not done in-vehicle.
Grok will also require premium connectivity or a Wi-Fi connection for the vehicle. At this point, we’re not sure whether Grok in your Tesla will also require you to sign up for SuperGrok, X Premium, or X Premium+, but Tesla is requiring you to sign into your Grok account. It’s just not clear whether the free version of Grok will work, or if you’ll need the premium version.
Grok User Experience
@greentheonly on X
Green also revealed the user interface for Grok for the first time. You’ll find many of the same features from the Grok app, but surprisingly, it looks like it’ll have a dark UI, even if you’re using light mode in your vehicle.
It appears that there will be a Grok app, likely for settings. However, Grok will largely operate in a modal, similar to voice commands, which are displayed near the bottom left corner of the screen.
There’s an on-screen microphone button, as well as drop-down menus for the voice and type of assistant you’d like to use.
Similar to the Grok app currently on mobile devices, you’ll be able to select from a set of voices and then define their personality. The available voices for now are the standard Ara (Upbeat Female), Rex (Calm Male), and Gork (Lazy Male).
There’s also a settings button, which, when expanded, allows you to enable or disable NSFW mode (including swearing and adult topics), as well as a Kids Mode, which will tone Grok down to be suitable for when kids are in the car.

How Grok Will Work (Button / Wake Word)
Users will be able to activate Grok by pressing a button, likely the same one that activates voice commands today. Grok will then remain enabled for the duration of your conversation, allowing you to go back and forth, asking and answering questions. To end your conversation, you’ll press the mic button again.
While it doesn’t appear to use a wake word yet, Green says that some code refers to a wake word, so it’s possible that this could be an option Tesla plans to activate in the future.
Replacing Voice Commands
The most significant implication of Grok’s future integration is in its potential to fully replace the existing and relatively rigid voice command system. Green notes that internally, this feature is part of the car assist module, and that eventually, the plan is for Grok to take over car control functions.
Unlike the current system, which requires specific phrases, a true conversational AI like Grok can understand natural language. This will enable more intuitive requests, completely changing how drivers interact with their car.
Language Support
@Greentheonly/X
Grok will also launch with multi-language support, similar to its current abilities in the Grok app. Green says that it already appears to have support for English and Chinese and one or two other languages.
Release Date
Grok appears ready to go from a vehicle standpoint, but Green wasn’t able to actually test it out. While development appears to be nearly complete in the vehicle, Tesla and xAI may still be working on some server-side changes to better integrate with the vehicle. If they plan for Grok to replace voice commands on day one, then it’ll need to be trained and be able to execute a variety of vehicle commands.
It’s possible Tesla is actively testing Grok or adding server-side changes to replace voice commands. However, it looks like vehicle development is nearly complete and Grok could launch as soon as the next major Tesla update, which is expected to be update 2025.24.
