Not a Tesla App

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.

The improvements include a seamless transition from WiFi to cellular data, eliminating dead zones, as well as hardware video decoded, which improves the Dashcam, Sentry Mode and lowers CPU usage, even while the vehicle is in use. However, there are many more. In total, we found eleven undocumented changes in this year’s holiday update.

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

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

Not a Tesla App

Even if your vehicle is connected to WiFi, it will now immediately connect to cellular data once the vehicle is put into drive or reverse.

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 New Signal Viewer Panel in Service Mode+ Allows You to View Real-Time Data

@scotsrule08 on X

Tesla’s latest software update, version 2025.2, brings new features to Service Mode, continuing the trend of improving in-vehicle diagnostics.

Currently, this feature is only available for vehicles with AMD Ryzen infotainment systems and requires Service Mode+, which is a subscription service aimed at technicians. Intel-powered vehicles aren’t supported yet, but we expect this feature to roll out to them as well unless hardware limitations prevent it.

Thanks to Spencer for providing an image of the panel in action.

Signal Viewer Panel

While update 2025.2.6 adds four service mode improvements, including updates to brake burnishing, charge port calibration, and noise recording panel improvements. In this article, we’ll focus on the new signal viewer panel.

This new panel offers a live data feed from selectable vehicle sensors. You select the signals you’re interested in and it’ll plot the signal on a graph. In addition to allowing you to view real-time signal data, it also allows you to record them.

The signals are searchable and can be easily added or removed from the panel. You can track up to 10 sensors, and the UI allows three of them to be viewable at once.

However, this is Service Mode and it’s more than just pretty looks. You can really dig down into these charts. You can pan them left and right through time, and tapping a specific point shows the exact value of that signal. The panel also supports pinch-to-zoom, enabling you to adjust the time scale across all panels simultaneously.

This feature is exclusive to Service Mode+, which requires a subscription to Tesla’s ToolBox3 software and a connection to a computer. It’s designed to help technicians diagnose issues related to signal quality, noise in the vehicle’s electrical systems, and signal variance in components during driving.

We’re excited to see Tesla’s continued focus on repairability, especially with additions like the Cybertruck’s Interactive Wiring Diagram and the launch of the Tesla Online Parts Catalog, which lets customers purchase parts directly.

Plus, with the reduced cost of ToolBox 3 subscriptions, even DIY enthusiasts now have access to tools that make Tesla repairs more accessible.

Tesla Introduces New Model Y Variants in Europe; Ends Launch Series

Not a Tesla App

Tesla has updated its Model Y lineup in Europe, introducing new standard configurations while discontinuing the limited-edition Launch Series. With the new variants now available, European customers will have more choices and cheaper options to pick from.

The Launch Series and some of its exclusive features will no longer be offered—except in the UK, where it remains available alongside the new lineup.

New Models Introduced

Tesla’s new Model Y lineup in Europe includes three main variants. The prices vary slightly from country to country.

• Rear-Wheel Drive (RWD): Priced at €44,990, this model is the most affordable new Model Y, but it also has the shortest range and is missing a few features available on other trim levels.

• Long Range Rear-Wheel Drive (LR RWD): Available for €49,990, this version is essentially the same as the RWD model, but with a larger battery. It has seen a €1,000 price increase compared to the outgoing Long Range RWD model.

• Long Range All-Wheel Drive (LR AWD): At €52,990, this model has seen a price drop of €2,000, making it a better deal than the previous LR AWD Model Y. This is also the only new Model Y to come with most of the same features as the Launch Series, including additional speakers, a subwoofer, premium materials inside the cabin and improved acceleration. Acceleration boost should also become available for this model, letting it match the performance of the Launch Series.

All Model Y variants come with all the improvements that we’ve discussed about the new Model Y, including the new front and rear light bars, improved aerodynamics, ventilated seats, improved heat and sound isolation, and the 8-inch rear touchscreen. Some exclusive options, like the Midnight Cherry Red paint, appear to no longer be available. However, Tesla has already said that they’ll be introducing new paint options for the Model Y in North America.

Compare Model Y Variants

Here’s how the various Model Y variants compare to each other:

Launch Series Ends

Not a Tesla App

The Launch Series, which debuted just weeks ago in Europe, has now been phased out. This limited-edition model was priced at €60,990 and included a suite of premium features comparable to a bundle deal you may find with other products. It came equipped with Full Self-Driving (FSD), Acceleration Boost, and exclusive badging on the rear liftgate, door sill plates, and puddle lights.

While the Launch Series is no longer available for new orders in most European countries, customers can still get a similar vehicle by opting for the Long Range AWD model and manually adding premium features like FSD. Acceleration Boost, which was standard in the Launch Series, is expected to become available for purchase once these vehicles are delivered or soon afterward. However, some exclusive elements, such as badging and trim details, will remain unique to the discontinued edition.

For now, the UK remains an exception, still offering the Launch Series alongside the newly introduced models.

Performance Model Still to Come

With Tesla now introducing the expected variants of the refreshed Model Y, one notable absence is the Performance model. While the Launch Series was fast due to the Acceleration Boost addon, there’s no doubt the Performance version will be in a league of its own.

What we saw Tesla do with the 2024+ Model 3 Performance variant was more than just using binned motors. The vehicle featured unique bumpers, a spoiler, an improved suspension, sport seats, Track Mode V3 and other features that made the vehicle stand out compared to the Model 3 AWD.

The Performance version of the new Model Y is expected to become available later this year, however, expect it to carry a $5-$8k premium over the AWD model.

Other Regions to Follow

As Europe phases out the Launch Series, other regions are expected to see similar changes. With the other models now revealed, owners in other regions have a better idea of whether they should buy the Launch Series or wait for the additional models to arrive.

Tesla naturally adjusts its offerings based on market demand, and if sales of the Launch Series remain strong in other parts of the world, Tesla will likely wait it out a little longer before offering the other models.
