This update continues Tesla's recent trend and introduces various new features.
You can now customize the Quick Action buttons
New Notifications
You can now choose to turn on notifications when Cabin Overheat Protection is activated. You can also choose to turn on or off notifications when your car is done preconditioning.
Tesla App 4.3 gives you more control over notificationss
Customizable Quick Actions
You'll now be able to customize the quick action buttons that show up underneath the car.
The app still limits you to four buttons, but it allows you to swap out any of the existing buttons for just about any function the app can control. You can set a quick action button for the trunk, defrost, Sentry Mode and many more.
If you'd like to make room for an additional quick action button, you can remove the Charge button and replace it with a button of your chosing. You can then access the charging section by tapping the battery icon instead.
Adjust Cabin Overheat Protection
Another new feature is the ability to adjust your Cabin Overheat Protection. Cabin Overheat Protection allows your car to try to keep the interior temperature under 105° F by either using the HVAC fan or air conditioner.
The three options are to turn off Cabin Overheat Protection, try to cool using only the fan, or cool using the air conditioner.

Using the air conditioner option will do the best job in keeping the cabin cooler, but could result in significant battery usage on hot summer days.
Many users are unable to access the ability to adjust the Cabin Overheat Protection setting. It looks like this feature may require your car to have update 2021.40.5 or later in order to function.
It looks like the Cabin Overheat Protection options will appear in the Climate section of the app. They should appear within the slide up drawer, next to the Defrost and Bioweapon Defense Mode buttons.
Widget Improvements
The app widgets have also been improved and now feature the same quick action buttons that you define within the app.
Pressing on a quick action button within the widget will open the app and execute the function automatically. Some functions have confirmations, such as defrost. Once the app is opened, you'll need to confirm that you want to turn on the defrost function.

Sentry Mode Live Access
Sentry Mode Live Access enables you to view live video feeds from the car's cameras directly on your phone. The feature has been available in previous iOS app updates, but Tesla is calling out it's functionality in this update as well.
Sentry Mode Live Access doesn't appear to contain any new features with this update.
Ability to Unlock Supercharger Floor Locks
In China Tesla uses floor locks on Supercharger parking spots to prevent other vehicles from parking in those spots. Up until today, it required a Tesla owner to scan a QR code on the lock in order to lower the lock and allow you to charge.
With this app update, Tesla is now allowing you to unlock the Supercharger spot within the app.
Superchargers in China have floor locks
It's a great update for individuals living in China, but these floor locks are unlikely to be expanded to other regions as Tesla starts allowing non-Teslas to charge at Supercharger locations.

In this article, we’ll cover Tesla’s updates on Optimus, batteries, and Tesla Energy.
Optimus
Tesla has been working away on their humanoid robot and continues to make progress in software and hardware.
First, Tesla is preparing the Fremont factory for the Optimus pilot production line, which is scheduled for completion later this year. Once it is, wider deployments of Optimus for internal use within Tesla’s facilities are expected as well. Tesla aims to have several thousand Optimus units working in its North American factories by the end of the year once the pilot production line is operational.
Tesla’s goals for production remain extremely lofty - 1 million units per year by 2030. However, they could face some challenges when ramping production.
Key components like the shoulder actuators use specialized permanent and rare-earth magnets, which are currently sourced from China. Due to recent Chinese restrictions on the overseas sale of these magnets, Tesla is seeking an exemption or alternative suppliers. They have not yet looked into modifying the shoulder actuator but will likely do so if they cannot obtain the necessary materials.
Batteries
Batteries are another item that Tesla’s teams have been working on behind the scenes for years now. The second generation of the 4680 - the Cybercell - has been IRA-compliant for some time now. This means that the Cybertruck is eligible for the US Federal EV rebate.
Tesla also achieved the lowest cost-per-kWh of any of its cells with the 4680 battery - and it is potentially one of the cheapest cells being manufactured by any vehicle battery manufacturer at this point. With dry-cathode still being worked on, Tesla may be able to squeeze more optimizations and cost efficiencies from the 4680 cells.
Additionally, Tesla is progressing with its plans for lithium refining and cathode production in the US, both of which are scheduled to commence in 2025. While the company says they’re no longer supply-constrained for non-LFP vehicle batteries, on-shoring production and sourcing critical minerals from nations outside of China will be key.
LFP batteries continue to be supply-constrained, namely for the Tesla Energy division. LFP batteries and their materials are sourced from China. Due to tariffs and limited exports, Tesla can’t obtain enough and is considering potentially building an LFP production facility in North America.
Energy
Tesla’s energy division is still experiencing some of the highest growth of any of its divisions. Year over year, Tesla saw a 154% increase in energy storage deployments, including both Megapack and Powerwall - for a total of 10.4 GWh deployed in just Q1 2025. While deliveries in energy storage remain volatile due to the nature of Megapack installations, Tesla expects growth to continue rapidly in this segment.
Tesla also deployed 1GWh of Powerwall 3 residential storage this quarter, marking its strongest quarter. Powerwall 3 has received positive feedback from customers, many of whom appreciate its new capabilities with its built-in inverter for solar.
Megapack is continuing to see demand increases, currently highlighted by utility-scale Megapack systems, as well as data centers requiring stable power delivery. Megafactory Shanghai is also online now and producing Megapacks - with an annual production capacity of 20GWh today and up to 40GWh in the future. The site has also produced over 100 Megapacks this quarter, which are all awaiting delivery.
There was a lot of interesting news from Tesla’s Q1 2025 Earnings Call, covering everything from FSD and Robotaxi - to the less glamorous but equally important Megapack and Powerwall.
Tesla is heavily leaning into artificial intelligence, and its insurance offering is just another example of how it’s improving its product or lowering costs by leveraging AI.
Tesla recently started offering an insurance discount in select states when drivers use FSD for at least 50% of their drives and now it’s introducing an AI to help handle customer claims.
Tesla has developed an in-house voiced AI agent that can assist customers in handling simple support requests for Tesla Insurance.
For customers calling in from those states, the new AI agent provides a unique way to address the most common support calls. And it’s not just answering common questions but actually making requested changes to the owner’s account.
Policy Changes
The first key item is that it automates policy changes. Simple policy updates, including adjusting your deductible or coverage limits, are now done via AI. For policyholders who are simply looking to make quick changes and don’t have any questions, this makes the process a lot quicker by not having to wait for a representative. Tesla isn’t eliminating representatives, but this could reduce the number of representatives required or reduce wait times.
Continue Where You Left Off
The second item here, highlighted by Raj Jegannathan from Tesla’s internal IT team, is that Tesla’s AI agent is able to offer summaries of the user’s last interaction with Tesla Insurance. It will summarize your last interaction and provide assistance on that particular topic if you need to continue it. That means that you don’t have to wait for a human to review your file - the AI will kick off right where you left off.
Tesla appears to be focused on improving efficiency and making support more accessible. While actual items like claims are left up to humans due to their inherently complex nature, this helps free up employees to handle more complex items. While there’s no doubt Tesla will continue to develop this AI like they do everything else, we may soon see it take on even more tasks.
More AI
This isn’t the first AI agent that Tesla has demoed - there is now a chat-based AI sales agent available on the front page of Tesla’s website, which is able to answer common questions on Tesla vehicles.
Tesla has also been improving their AI support tool available in the Tesla App is able to provide feedback on common issues and also guide users towards either solving the problem or placing a support request.
Tesla’s strategy here is to influence the cost-heavy areas associated with having humans address simple requests and instead leverage AI, which can offer instant answers and reduce support costs.
Roll Out to More States
While this new AI is currently limited to just 12 states, it is likely to follow Tesla Insurance’s expansion. Insurance seems to have been at a bit of a standstill lately. Tesla continues to improve features such as the improvements to Safety Score V2.2, but we haven’t seen Tesla roll out support to new states since it added Minnesota in November of 2022.
