An Early Look at Tesla's 2023.20 Update and Its Features

Tesla is introducing the ability to track your tire mileage in update 2023.20

Preparations are underway for Tesla's next software update, version 2023.20. Although currently in testing, this update has been drawing attention since it was first noticed last week. Considering Tesla's 2023.12 update brought numerous new features, it appears this next may be smaller. However, we now have our first look at some of the features included in Tesla's 2023.20 update.

Ability to Track Tire Mileage

A noteworthy improvement under the upcoming update pertains to tire service tracking. Post-update, vehicle owners can track how many miles have been driven since their last tire service. This feature can prove valuable for monitoring mileage since your last tire rotation, changing to new tires, or switching between season-specific tires.

You or your service center will need to manually reset the counter each time your tires are serviced. You can view the mileage traveled or reset your counter by navigating to Controls > Service.

The official release notes state:

Go to Controls > Service to see how many miles it's been since your last tire service.

When you get your tires rotated, replaced, or swapped, tap 'Reset' to reset the counter.

Furthering Global Reach: Text Size Adjustment

Another feature gaining more ground is text size adjustment. While 'Text Size' was introduced in the 2023.12 update, the ability to adjust the size of the text in the vehicle's UI was limited to select languages. The feature has now been extended to all languages supported by Tesla. This expansion affirms Tesla's commitment to accessibility for its global user base, ensuring a seamless experience across different regions and languages.

While the Text Size feature in update 2023.12 only applied to the Model 3 and Model Y, it's not clear whether update 2023.20 also introduces the feature to the Model S and Model X. Based on Tesla's feature release history, this feature will likely apply to at least the redesigned Model S and Model X in the future, but it's not immediately clear whether that is happening with this update.

The release notes for 2023.20 state:

Large text size feature is now available in all supported languages.

To update your settings, go to Controls > Display > Text Size.

Release Date

Although Tesla does not provide release dates for upcoming software updates, we may see update 2023.20 start rolling out in the next week or two. This timing can change if Tesla uncovers issues that need to be addressed before a public release.

2023.12 Update: A Look Back

As we anticipate the rollout of 2023.20, it's worth reflecting on the last major update - 2023.12.1. This update significantly enriched Tesla's features, particularly for Model 3 and Model Y. One standout was steering wheel customization. A long press on the left scroll button revealed a host of adjustable settings and functions.

Moreover, introducing the new search function facilitated more accessible access to controls and settings, along with points of interest that included photos and reviews. The ability to adjust wipers using the steering wheel scroll wheel emerged as a valuable, undocumented feature.

Perhaps one of the most user-friendly updates was the option of Standard or Large text sizes for the touchscreen display, which now applies to all languages under the 2023.20 update.

Other improvements included optional gear chimes for Model 3/Y, the transition of Tesla's Spotify player to a web-based format, enhanced phone call controls, and vision-based speed assist feature expansion. Tesla also broadened Zoom availability to more countries, added writing support for legacy Model S and Model X in China, and continued to make user interface enhancements.

While this is an early look at the upcoming features update 2023.20, it provides a glimpse into Tesla's continuing pursuit of improving user experience and convenience. There may be additional features in this update that are not listed here since not all Tesla features are available for every vehicle or region.

As we wait for the public release, it's evident that Tesla continues to push boundaries in its software development, setting high standards in the electric vehicle market.

Tesla Activates In-Cabin Radar in Software Update 2025.2.6

Not a Tesla App

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.

Why Not Vision?

Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.

What Tesla Announced

Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.

Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.

New Feature in Update 2025.2.6

Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.

In the release notes, Tesla describes the update as:

“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”

For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.

Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.

Supported Models

Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.

The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.

At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.

We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.

Tesla Updates App: Adds Robotaxi Code, New Model Y Models and New Tesla Service UI

@olympusdev_ on X

Tesla has updated the Tesla app to version 4.42.0, and this time, it’s more than just bug fixes. The app includes a new service interface, introduces support for the new Model Y, and, for the first time, includes some code for the Robotaxi coming later this year.

This update was released for iOS and should be available on Android within a few days.

Refreshed Model Y 3D Model

First up in the update is the introduction of the 3D model for the refreshed Model Y. Interestingly, while we all know it as Juniper, the file code name inside the update lists the vehicle as “Bayberry.” The Bayberry name was introduced in Tesla app update 4.41.5.  Tesla’s internal code names sometimes change as the vehicle evolves - and we’ll continue to refer to it as the refreshed or new Model Y for ease of understanding.

As usual with Tesla’s 3D models in the app, there’s a lot of detail, although it’s not easy to see since you can pinch and zoom the model in the app. The 3D models used in the app are actually the same models that Tesla uses in the vehicle, although sometimes they include different lighting effects, but they’re all highly detailed.

Robotaxi API

Tesla has added a new endpoint in their app for Robotaxi - and it’s the very first Robotaxi or Cybercab-related item we’ve seen in the app. With the Robotaxi fleet launching in June, according to Tesla, it looks like they’re now adding support to the Tesla app.

What the Robotaxi interface is supposed to look like in the future.

Not a Tesla App

The new app API is called “rides_feedback_upload,” which seems pretty explanatory. Tesla will need to gather a lot of information on ride quality and all the little things in between. What better way than to get feedback directly from users?

While Tesla previously released prototype images of what the Robotaxi app will look like, the introduction of this API into the Tesla app leads us to believe that Tesla will utilize the current app for Robotaxi use.

Updated Service Interface

The Updated Service Panel in the Tesla App

Not a Tesla App

Tesla has released an updated UI for the Tesla Service panel, and we have a ton of details on these changes. This new pane displays appointment details more prominently. If you have a service appointment scheduled, you’ll now see a lot more details on the main service screen. The app will now display:

• Your current service status

• Appointment date and time, which you can now tap on to add the event to your calendar

• Address and hours of the service center. You can now also tap on the address to open up the location in your maps app

There’s also a new appointment details screen (the right portion of the image). This screen displays additional details that were previously unavailable, such as your transport type. The app will display whether you’ll get a loaner vehicle, demo vehicle, or something else.

There are a ton of user experience (UX) improvements in this update regarding service, including clearer language, improved UI fixes to images, and more.

Tesla has been making a lot of positive updates to the Service-related sections of the app lately, and we’re happy to see these coming rapid-fire. Tesla Service is now easier to use and understand. In the previous app update, Tesla also added the ability to pull down to update the service screens.
