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.
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’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
