Tesla usually packs a bunch of smaller, undocumented changes into every update, and this year’s holiday update isn’t any different. In fact, the holiday update contains massive improvements under the hood, especially for vehicles with the Intel Atom processor. The undocumented changes in this update are just as good as the features themselves, and for some owners, they may be even more of a gift than what Tesla has outlined in the release notes.
Come with us as we go through each feature that may have gone under the radar.
Update: Since we originally published this article, there have been an additional two undocumented changes found. They’re listed below.
Explicit Audio Content
The explicit content setting now applies to Apple Podcasts in addition to the 'Streaming'
Not a Tesla App
In the Audio Settings Options section, Tesla lets you block explicit content. Until now it only applied to the music service Tesla calls ‘Streaming,’ which is Slacker. However, with update 2023.44.30, this now applies to the new Apple Podcasts app as well. Unfortunately, it still does not apply to other streaming services such as Spotify or Apple Music yet.
More Wheel & Tire Options
New wheel options
Roz_420
Under the Wheel & Tire section, you can now select from additional wheel options. Tesla has added two new Gemini wheel options. Although the metallic aero wheels are only available in China, you can now select them from the Wheel & Tire menu in other regions as well. This will update your vehicle’s visualizations on screen and in the app to show these wheels instead of the vehicle’s default wheels.
The other new option introduced is the Gemini Cap Kit wheel option, which is the same Gemini wheel, but with the covers removed and with the bolt covers, known as the cap kit added.
Switching your wheels in these menus will cause the infotainment system to restart.
Improved Transition to Cellular
Tesla has improved their transition from Wi-Fi to cellular connections
Previously, if a vehicle was connected to WiFi, it would often not have an internet connection for a period of time until the cellular connection was established.
The transition from WiFi to cellular now appears to be instant. Tesla may be activating the cellular connection as you enter the car, instead of waiting until the vehicle is put into drive.
Improved Reverse Functions
These has made two improvements to the vehicle while in reverse

There are two improvements to reverse in this update when the vehicle is in reverse.
The vehicle's visualization will now display reverse lane markers when the vehicle is in reverse, indicating the vehicle's path.
For vehicles equipped with ultrasonic sensors, the update brings an innovative feature - the distance to objects behind the vehicle will now dynamically change based on the steering wheel's position (video). For example, if the steering wheel is centered and will go straight backward, then the distance to an object will be for the object behind the vehicle. However, if the steering wheel is turned, then the distance will be for the object that is in the vehicle's direction.
View Supercharger Amenities on Map
When viewing details about a Supercharger in the vehicle, the amenity icons are now buttons that can be tapped to view the locations on the map. Before, Tesla would show you what type of amenities were nearby, but you can now view the exact shops or stores.
Autopilot / FSD Beta Strike Reset
FSD Beta strikes have been reset in the holiday update
Not a Tesla App
With the holiday update, FSD Beta strikes have been reset for everyone. This gives everyone a clean slate when using the updated system that now applies to FSD Beta and Autopilot use.
If your vehicle has a cabin camera, you’ll lose access to Autopilot and FSD Beta after accumulating five strikes. If your vehicle doesn’t have a cabin camera, then you’re limited to three strikes.
Cabin Camera Privacy
You can now view the features the cabin camera is used for
Not a Tesla App
You can now view which Tesla features have access to the cabin camera. Simply navigate to Controls > Software > Cabin Camera.
The vehicle will display all features that are enabled and have access to the vehicle's interior camera.
Dashcam Icons
Tesla has made various improvements to the vehicle's Dashcam feature
Not a Tesla App
The dashcam now features an icon that is more informative. The dashcam icon will now display these states:
Saving / Loading: This icon features a gray badge with arrows letting you know the dashcam is saving or retrieving footage to the USB drive.
Saved Footage: After successfully saving footage to the USB drive, a green checkmark badge will now briefly appear on the dashcam icon.
Error / Not Recording: If there is an error with your dashcam, USB drive or recording is turned off, there will be a gray badge with an 'X' that signifies that the dashcam is not actively recording.
Paused: A red pause badge shows up on the dashcam's icon if the dashcam is temporarily not recording, like if the Dashcam Viewer is actively being used.
Automatic Wipers
Windshield wipers no longer need to be set to Auto while in Autopilot
Not a Tesla App
Automatic windshield wipers can now be turned off, even while Autopilot or FSD Beta is enabled.
Previously, you could change the time interval between wipes, but you could not turn off the wipers completely.
Dashcam Viewer Improvements
Tesla's Dashcam viewer is now much faster
Not a Tesla App
Thanks to hardware video decoding, the Dashcam Viewer is now faster and more responsive. When scrubbing the progress bar, video is now smoother and jumps around less.
Tesla Theater Improvements
Thanks to hardware decoding, Tesla's video services are also seeing improved performance
Not a Tesla App
Similar to the Dashcam Viewer improvements, Tesla Theater is now much faster and smoother as well. Improvements are noticed while browsing content, playing content and minimizing Tesla Theater.
Automatic Emergency Braking, Now Required
If you have Autopilot or FSD enabled in settings, then AEB is now required
Not a Tesla App
Automatic Emergency Braking, which can help stop your vehicle for perpendicular dangers, or in reverse, must now remain enabled if your vehicle is set up to use Autopilot or FSD Beta, even if they are not active.
Ability to Turn Off Automatic 911 Calling
Automatic 911 calling is an optional feature
Not a Tesla App
With this update, your vehicle will automatically call 911 if airbags are deployed and your phone is actively connected to the vehicle via Bluetooth.
The vehicle shows a countdown in such as situation, which allows you to cancel the call, however, the feature is optional and can be turned off by navigating to Controls > Safety > Automatic 911 Call.
The holiday update appears to have been a massive clean up by Tesla, where they not only improved performance but included many quality-of-life features. This is resulting in a smoother experience for owners and hopefully leaves some additional bandwidth for additional features in the future.

Tesla’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.
Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.
Semi Factory & Production Ramp
Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.
Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.
Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.
Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.
New Tesla Semi Features
Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.
New Electric Power Take-Off (e-PTO)
The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.
Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.
On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.
46 Semi Charger Sites Coming
The 46 new MCS sites coming soon.

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.
This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.
The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.
Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.
B-pillar Camera Recording
With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.
This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.
Updated Dashcam Viewer
These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view that allows you to view four cameras simultaneously. It also allows users to jump back or forward in the video in 15-second increments.
However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.
We have confirmed that Tesla is only adding the additional camera recording on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.
For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.
While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.
Update: Tesla is including the new Dashcam viewer for Ryzen vehicles.
New Dashcam Viewer is Available on HW3 / Ryzen Vehicles
Tesla doesn’t include the new Dashcam Viewer as a feature in the 2025.14.3 release notes, but owners with Ryzen-based HW3 vehicles are receiving the improved Dashcam player. However, they’re only receiving the improved player, not the B-pillar camera recording. The new player is a worthy addition, so it’s great to see Tesla include this feature even if B-pillar recording isn’t possible.
The new player includes four improvements:
New grid view that lets you view four cameras at the same time
Different camera views, including the grid view are spread out across the bottom instead of at each corner
You can jump back and forward in 15-second increments
Users can jump to the next Sentry Mode video by tapping the button on the top right corner, making it easier to jump to the next event instead of having to go back to the list of events.
Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.
Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.
Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.
Adaptive Headlights
Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.
All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.
If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.
Legacy Model S & Model X
As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.
Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.
These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.
While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
