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.

NHTSA Probes Tesla’s Robotaxi Plans; Seeks Answers on FSD in Poor Weather

By Karan Singh
Not a Tesla App

As anticipation builds for Tesla’s Robotaxi network debut in Austin, potentially just a few short weeks away, the National Highway Traffic Safety Administration (NHTSA) is turning its official eye onto Tesla. The ask? How will Tesla’s FSD handle the unpredictable realities of challenging weather?

The NHTSA Request

The NHTSA has sent a formal letter to Tesla, which was made public on May 12th, requesting detailed information about Tesla’s Robotaxi service. The NHTSA inquiry centers specifically on the safety and performance of FSD when faced with reduced visibility conditions like rain, fog, and sun glare. The request is tied to an ongoing NHTSA investigation, which was initiated in October 2023, examining Tesla’s FSD and Autopilot suite following incidents in poor visibility.

Tesla’s executives, including Elon Musk, have previously stated that the company is full steam ahead to launch Robotaxi in Austin this June. However, NHTSA’s pointed questions come even as Tesla has recently discussed its plans to work on region-specific and weather-specific FSD training.

Tesla’s executive leadership acknowledged the need to adapt the system to diverse environmental and weather conditions. Now, regulators want specifics on how Tesla intends to address environmental conditions and how that translates to operational safety for the fleet.

Request Breakdown

NHTSA’s letter outlines a need for detailed information from Tesla before the service launches and covers several key areas. We’ve broken this down into various sections below:

Deployment Scale

NHTSA is looking for the exact number of vehicles and models that will be part of the initial Austin fleet, and what the projected service availability times would be for said fleet. Tesla has previously said it’d launch with 10-20 Model Ys, but looks like NHTSA is looking for additional details.

Oversight

In terms of oversight, NHTSA is looking to confirm whether the Robotaxis will operate under real-time supervision of Tesla’s employees, either remotely or in-vehicle.

This is a question on our minds as well. A recent app update suggested that Tesla could have a driver in the vehicle, but it wasn’t clear whether this was referring to Tesla’s own fleet or customer-owned vehicles. The only thing we have heard officially from Tesla is that Tesla “may” use remote support, but that they were still looking into it.

Adverse Weather Capabilities

This is the meat and potatoes of the request - how will Tesla ensure safety during sun glare, fog, heavy rain, snow, or dust? What specific protocols are triggered if poor visibility is encountered mid-trip? Will the vehicle pull over or call home and cancel rides?

Sensor Technology

Surprisingly, NHTSA is looking for details regarding the vehicle the Robotaxi sensor suites and how Tesla intends to use those sensors to ensure safe operation under varied conditions. NHTSA has had previous submissions from Tesla in regard to its sensor suite and how it uses the technology, so it feels odd that they are requesting another batch - but this could be related to the use of the next generation of FSD (Unsupervised).

Compliance

Does Tesla’s FSD system adhere, either fully or partially, to established industry standards for autonomous driving? This likely refers to the NHTSA Automated Vehicles for Safety guidebook, which lays out the “L0 to L5” driver assistance vs automation system.

Future Expansion

Finally, NHTSA is looking for the timeline for enabling Robotaxi functionality on vehicles not directly owned or controlled by Tesla. Tesla has already come out and said that customer-owned vehicles wouldn’t be allowed on the robotaxi network until 2026, but obviously, NHTSA wants to hear directly from Tesla and likely has more specific questions covering a wide variety of potential issues.

These questions will likely have to be answered with considerable amounts of data and justification for the NHTSA. Once all that is done, Tesla will be in a better position to receive regulatory approval at a larger scale than just within the city of Austin or the state of Texa with the NHTSA’s backing.

Successfully addressing this letter will be the key for Unsupervised FSD moving forward, but Tesla hasn’t issued a public response to the agency’s letter, and likely won’t in a public manner. So we’ll have to wait and see how the launch of the Robotaxi network pans out next month.

FSD V13.2.9 Rolls Out for HW4 as Part of Tesla’s 2025.14.6 Update

By Karan Singh
Not a Tesla App

After an 84-day wait since the last FSD update, Tesla has finally begun rolling out a new version of FSD V13 to its AI4-equipped vehicles. This new release, V13.2.9, is rolling out to all vehicles, including the Cybertruck.

Unfortunately, since it’s a minor point release (from V13.2.8), the release notes are the same, and Tesla hasn’t included a change log or changed what’s coming in the future.

Software Update 2025.14.6

The FSD update is rolling out with Tesla software update 2025.14.6. Interestingly, update 2025.14.6 is seeing a wider distribution and is also being made available to vehicles without FSD and outside North America. For those vehicles, this update just includes bug fixes.

TCU Fix

There’s one fix in particular that’s expected to be included in this update, according to a message from Tesla Service. In earlier 2025.14 updates, there was a bug in some vehicles that prevented some vehicles from falling asleep properly due to a Telematics Control Unit (TCU) issue. This bug caused additional battery drain since some of the vehicle’s systems remained on.

Tesla Service said they planned to include a bug fix in update 2025.14.6, but it hasn’t been confirmed whether the fix actually made it out in this release.

Early Access Users and More

FSD v13.2.9 was first rolled out to Tesla’s standard Early Access group, including well-known community members and content creators. It has also reached participants in the newer, Texas-based Early Access Program, suggesting that the update is relatively stable and may serve as a foundation for upcoming FSD releases.

Tesla could be intending to use the Texas Early Access Program to test various features, perhaps related to the upcoming Robotaxi network launch in Austin. While this is plausible, it is merely speculation, and we’ll be keeping a close eye on that group to see what exactly Tesla does.

HW3 Users

While Tesla has recently been including FSD updates for HW3 and HW4 in the same release, this update does not include any changes for HW3 users. HW3 vehicles that are receiving this update are staying on FSD V12.6.4, which means that whichever fixes this update includes they’re specific to FSD V13 or HW4.

Point Release - Not Much New

Being a point release, V13.2.9 isn’t expected to introduce any major new capabilities. Tesla hasn’t provided specific release notes detailing changes from V13.2.8.

Hopefully, Tesla has taken into account recent user feedback on V13.2.8 about lane centering and lane selection, and this update addresses some of those issues. However, early feedback is that those issues are still present.

There is always potential for a more substantial update in the near future, so keep your fingers crossed, but after such a long wait, we expected more to be included. It seems like Tesla may have felt the need to address a bug in this release instead of waiting for the next major release, which is expected to either be FSD V13.3 or FSD V14.

Update 2025.14.6

FSD Supervised 13.2.9
Installed on 6.8% of fleet
499 Installs today
Last updated: May 14, 12:35 pm UTC

Roll Out

The fact that Software Update 2025.14.6 is going out wider than the Early Access audience suggests that Tesla is confident in this release and that it likely only includes very minor changes. We expect this update to continue going out over the coming days.
