Tesla update 2023.12.1 adds several exciting features
Not a Tesla App
Tesla's 2023.12.1 software update brings various new features and enhancements to its vehicles. One of the most significant updates is the steering wheel customization, specifically for Model 3 and Model Y. The video below shows how easy it is to use and navigate multiple menus.
The left scroll button now has multiple uses, enabling drivers to adjust settings such as brightness and Acceleration Mode and perform actions like toggling the Camera App, opening the glovebox, and saving Dashcam footage. To access these options, long press the left scroll button to display a list of functions and scroll through the list. To choose the default function, go to Controls > Display > Scroll Wheel Function.
Steering Wheel Customization is currently only available for the Model 3 and Model Y, but that may be changing soon.
The Tesla release notes reveal an icon with an upward arrow on the car, suggesting possible future suspension adjustments from the scroll wheel menu — a feature currently exclusive to Model S/X.
New Search Function
The new search function, located under the menu, displays options as you type and offers suggestions for easier access to controls and settings. This should make it easier to adjust specific options, especially if you're unsure which menu they're under.
Points of Interest with Photos and Reviews
When selecting a point of interest or Supercharger location, the updated software now includes photos and reviews to provide users with more information. For example, you can tap on a restaurant and immediately receive information about the menu, pictures and reviews.
Undocumented Wiper Adjustment Feature

The ability to adjust wipers using the steering wheel has been discovered as an undocumented feature in the 2023.12.1 release notes. You
You can now adjust the windshield wiper speed by using the scroll wheel on the steering wheel. First, press the button at the end of the left stalk to activate the windshield wipers and have the controls appear on the screen.
You can then tilt the left scroll wheel left/right to cycle through the various speeds of the windshield wipers.
There are various enhancements and changes to the UI in this update that Tesla didn't mention in their release notes. For a full list of all those changes, be sure to check our the release notes for update 2023.12.1, where we list all the official release notes along with undocumented changes.
Optional Gear Chimes for Model 3/Y
Gear chimes have been added as an optional feature for Model 3 and Model Y vehicles. Similar to the same noise users hear when activating and deactivating Autopilot, a chime will provide an audible alert when the car is put in drive, park and reverse. This update is expected to extend to Model S/X and is available worldwide.
Spotify Web-based Player and Phone Call Controls
According to @GreenTheOnly, Tesla's Spotify player has transitioned to be a web-based player, similar to Apple Music. It appears that Tesla will be transitioning all music services to leverage their web-based player, allowing quicker development.
In the new Model S/X and Model 3/Y, you'll now also be able to control phone calls from the steering wheel. The left scroll button can be used to answer or decline incoming calls, mute/unmute during a call, or hang up.
Speed Assist
Speed Assist now leverages the car's cameras to detect speed limit signs, improving the accuracy of speed limit data on local roads and highways in select countries. Detected speed limit signs will be displayed in the driving visualization. The vision-based speed assist feature now includes support for several additional countries, such as Australia, Sweden, Portugal, and Luxembourg.
Expanded Zoom Availability in Multiple Countries
Tesla has extended Zoom availability to more countries, including Germany, France, Italy, the Netherlands, Norway and others. If you have a Zoom meeting in your Calendar, tap the link to start or join your meeting automatically. Participant video and screen sharing are only visible while parked and will switch to audio-only if you drive. It is the driver's sole responsibility to consult and comply with all local regulations while using Zoom. To access Zoom, tap Application Launcher > Zoom.

Perhaps one of the biggest changes is that you can now choose between Standard or Large text sizes for the touchscreen display in the Model 3 and Model Y. Navigate to Controls > Display > Text Size to adjust your preference. With these exciting new features and improvements, Tesla's 2023.12.1 software update enhances the overall driving experience for its users.

Another quarter has passed, and that means it’s time to submit questions and vote for Tesla’s Q2 2025 Earnings Call. While Q1 was a tough quarter for the company, Q2 saw some recovery in sales, although there’s still some work to be done.
However, there’s always a lot to be excited about during Tesla’s Q&A session, where we usually learn a lot about future software improvements and upcoming vehicles. We may hear more about FSD Unsupervised, Robotaxi, or the more affordable vehicle, or its upcoming larger 6-seater Model Y, the Model Y L. Tesla also mentioned a potential FSD price hike back in the Q1 2025 Earnings Call, so that could be something that is brought up as well.
Tesla’s Q2 So Far
Tesla has already released their Q2 2025 Production and Delivery numbers, which were up from Q1 of this year, but still down compared to Q2 last year.

How to Submit & Vote
Tesla lets shareholders submit a question that will be voted on and may be answered during the Q&A session. To submit your own question or vote on an already submitted question, you’ll need to be a verified shareholder. You can go to Say’s platform and link your brokerage accounts.
Once it is verified, you’ll be able to log in and vote your shares on your own question, or on someone else’s question.
Here’s the link to get started on Say’s Tesla Q&A. You must submit your questions and votes by July 23rd, 2025, at 4:00 PM EDT.
Top Questions So Far
Unsurprisingly, people have already been submitting questions, and here are the top ones so far.
Can you give us some insight how robotaxis have been performing so far and what rate you expect to expand in terms of vehicles, geofence, cities, and supervisors?
What are the key technical and regulatory hurdles still remaining for unsupervised FSD to be available for personal use? Timeline?
What specific factory tasks is Optimus currently performing, and what is the expected timeline for scaling production to enable external sales? How does Tesla envision Optimus contributing to revenue in the next 2–3 years?
Can you provide an update on the development and production timeline for Tesla’s more affordable models? How will these models balance cost reduction with profitability, and what impact do you expect on demand in the current economic climate?
Are there any news for HW3 users getting retrofits or upgrades? Will they get HW4 or some future version of HW5?
When do you anticipate customer vehicles to receive unsupervised FSD?
And here are some other ones we found interesting:
Have any meaningful Optimus milestones changed for this year or next and will thousands of Optimus be performing tasks in Tesla factories by year end?
Are front bumper cameras going to be necessary for unsupervised full self driving? If so, what is the companies plan to retrofit vehicles that do not have them?
Will there be a new AI day to explain the advancements the Autopilot, Optimus, and Dojo/chip teams have made over the past several years. We still do not know much about the HW4.
Earnings Call Details
Tesla will hold its earnings call on Wednesday, July 23rd, at 4:00 PM EDT. It's still early for an access link, but we’ll make sure we have a link up on the site before the earnings call that day.
If you do miss the earnings call, no worries. We will provide a full recap following the call, and we’ll also do some in-depth dives into what was said and what we know.
Tesla’s Summer Update, 2025.26, has finally launched, bringing with it a batch of interesting new features for some, and a bunch of quality-of-life improvements for everyone else.
Grok AI Assistant
The star of the Summer Update is Grok, xAI’s conversational AI assistant, which has now landed in Tesla vehicles. For now, it's available in any Tesla that has an AMD processor and is potentially coming to Intel-based vehicles in the near future. The feature is also only available in the U.S., but it’s expected to expand to other regions — hopefully soon.
Grok is in its first iteration as an in-vehicle assistant, and for now, cannot control the vehicle, which means that Tesla’s voice command system is still intact. However, there is a lot it can do already. Grok is activated by pressing and holding the voice button (right scroll wheel on older vehicles), while a short press of the button is still reserved for voice commands. Grok will support a wake word in the future, letting you activate it without pressing a button.
You don't need to sign into Grok to use it in your Tesla!

Once Grok is open, which can also be done by tapping the Grok app icon, users can tailor the AI personality according to their preferences by selecting a persona and voice of their choice.
There are also several other settings for Grok under the settings button. You can enable NSFW mode, Kids Mode, or disable access to your vehicle’s location.
Grok has contextual awareness of your vehicle location, which means it can provide relevant answers to questions like “Where should I go for dinner?”
Logging In Not Required
Grok is free with Premium Connectivity, or if you’re using your phone’s hotspot feature or connected to WiFi, so anyone can try it for free. In fact, you don’t even need to log in to start using Grok. However, logging in adds some additional features.
If you’d like to log in, you can do so by scanning the QR code in the vehicle, which will provide chat management and transcripts, SuperGrok access (if you pay for a subscription), and better privacy control.
Tesla has added a new Light Sync feature that pulses the vehicle’s ambient lighting in sync with the music being played. This option is turned on under Toybox > Light Sync. There are also a few options, including the ability to match the ambient light colors to the album’s artwork, instead of using your selected color.
In addition, in Park you can enable Rave Cave when parked, which cranks up the ambient lighting brightness to the maximum.
Dashcam App Update
The Dashcam app now allows you to adjust playback speeds, just like the older Dashcam Viewer, which is still used on Intel-based vehicles.
In addition to adjusting playback speed, you can now adjust the video view so that it’s displayed without being obstructed by the buttons at the top (video below). The difference is small, but could be useful if you’re trying to see something slightly out of view or that’s hidden behind the top Dashcam buttons.
While the Cybertruck has also received the updated Dashcam Viewer with this update, it does not have the new B-pillar camera recordings like other HW4 cars.
Sentry Mode is getting one of the best uses of the vehicle’s ambient lighting that we’ve seen so far. The ambient lighting will now slowly pulse red while Sentry Mode is activated to grab someone’s attention, instead of just relying on the vehicle’s display.
While you can disable Sentry Mode sounds, we’d love to see an even more stealthy Sentry Mode that also disables the ambient lighting and screen, allowing the vehicle to record without anyone being aware.
Since the ambient lighting is being used in this case to make people more aware of a feature, Tesla could also use it in other modes, such as Dog Mode.
There are a lot of potential uses for ambient lighting. Tesla can make it glow while the vehicle is charging, with the brightness potentially related to the vehicle's charge level.
When you navigate to a Supercharger, new icons in the charger list will indicate locations that require valet service or pay-to-park access.
Upon arrival at the location, a notification will appear on your screen, displaying important details such as access codes, parking restrictions, level/floor information for parking garages, and restroom availability. This information will also be available on the site card in the navigation.
Equalizer Presets

Tesla has moved the audio settings from the music player, directly into the vehicle settings — making them much easier to find. In addition to creating a new “Audio” section in settings, you can now create and save equalizer presets.
Each preset can have a name, custom EQ settings, and a setting for immersive audio.

Onboarding Guide
Not a Tesla App
Tesla has introduced a new Onboarding Guide for new owners. The guide covers driver settings, touchscreen use, steering wheel and seat setup, and how to control key portions of the vehicle, including lights, wipers, and Autopilot features.
The Onboarding Guide is automatically initiated when a new owner accepts delivery of a Tesla, or can be manually initiated at any time by going to Controls > Service > Onboarding Guide.
This appears to only be available for the new Model 3 and new Model Y.
In typical Tesla fashion, this 2025.26 update is rolling out gradually in small waves initially. Three waves have already gone out, so all signs are looking good for it going into a wide release soon.
