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.

Tesla Update 2023.12.1 in Action

Legacy S/X Writing Support in China

Writing support has been added to legacy Model S and Model X vehicles in China, expanding the functionality for these owners.

Text Size Customization

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.

This comprehensive overview of Tesla's 2023.12.1 software update showcases the automaker's commitment to continuously improving its vehicles' features and driving experience for its users. With each update, Tesla further cements its position as a leader in the electric vehicle market.

Tesla Accelerates India Entry: Eyes Gigafactory India

May 15, 2025

Tesla’s much-anticipated official entry into the Indian market appears to be shifting to a higher gear, with recent reports from Business Standard (paywall) indicating that Tesla is now looking into establishing Gigafactory India. Business Standard points to Tesla exploring land options in Satara, Maharashtra.

Satara is about 250km (155 mi) from the Port of Mumbai, placing it in an excellent location to easily receive parts and materials from other countries, as well as ship completed vehicles elsewhere around the world. The potential facility is reportedly planned as a “Completely Knocked Down” or CKD assembly plant, which means that Tesla would import parts and then assemble them locally.

This is key to Tesla’s strategy in addressing India’s traditionally high import tariffs on fully built vehicles, which have been a major hurdle for Tesla in the past. This push aligns with India’s updated EV policy, which calls for reduced import duties on EVs priced at $35,000 USD or above for companies that commit to investing at least $500m USD in local manufacturing facilities between 2024 and 2027.

According to the report, Tesla is prepared to invest substantially more, with figures around $2-3 billion USD cited for a plant capable of doing final assembly on up to 500,000 vehicles. Tesla supposedly aims to roll out the first locally assembled vehicle from the facility no later than March 2026.

Building the Indian Foundation

Beyond just manufacturing plans, Tesla has been actively laying the groundwork for its future Indian operations. Tesla has reportedly finalized leases for its first showrooms in Mumbai and Delhi - two of the largest cities in India. An office space in Mumbai to headquarter Indian operations is also on that leasing list.

Tesla has also begun to hire its initial tranche of employees, with over 30 positions already posted. Tesla is also hiring Autopilot Vehicle Operators in several locations, indicating that Tesla intends to test at least the FSD suite in one of the most complex traffic situations around the world.

Elon Musk also confirmed that he plans to visit India and speak to the Indian Prime Minister, likely to broker a deal focusing on building out Tesla’s presence and bringing new technology to the country.

The road to India has not been without its complexities. Reports confirmed the resignation of Prashanth Menon, Tesla's India head, with oversight of Indian operations temporarily shifting to Tesla's China team. Furthermore, earlier discussions with potential joint venture partners, such as Hyderabad-based Megha Engineering for land acquisition, reportedly did not materialize, leading Tesla to explore other avenues and locations like Satara.

Despite all the setbacks, Tesla’s efforts indicate that they are more determined than ever to make a formal and official entry into the Indian market.

Tesla's Spring Update Tear Down: New Grok Code, Ridesharing Features and More

May 15, 2025

Tesla’s software updates often contain far more than the release notes show, whether they’re undocumented features or preparation for the next big thing. The 2025 Spring Update is no exception - it’s filled with undocumented changes and, of course, new, inaccessible code that points to upcoming features.

Tesla hacker greentheonly on X has been digging into update 2025.14 and found some intriguing additions and hints about what’s coming next, so let’s take a look.

Grok Incoming

New hidden UI elements have been found pointing towards the integration of a Grok-powered smart assistant for Teslas. This includes references to a “personality” button, just like the Grok app. Tesla is likely hard at work on an advanced conversational AI and integrating the ability to control your vehicle.

Grok is the smart assistant that’s expected to replace the ancient voice commands that are available today. However, expect anything beyond vehicle commands to require Tesla’s Premium Connectivity.

While none of these new elements are active just yet, it is a good indication that it is likely on its way quite soon.

Siren Detection UI Removed

Code related to user-facing elements for siren detection has now been removed. We’ve confirmed that the orange dot is still in place with the Spring Update, but elements related to future changes and a UI for siren detection have since been removed from the code base.

Removals don’t indicate much - Tesla could be refactoring the code while they’re working on this or have changed directions on how to implement a future.

Insights into the New Dashcam Viewer

More significantly, for users on HW3, Green reported that the newly improved Dashcam Viewer isn’t just an improved version of the video viewer, but it was built from the ground up, and it’s now web-based. This technical detail explains why the updated viewer is only rolling out to AMD Ryzen vehicles and not older, Intel-based vehicles. HTML-based apps are often quicker to develop but usually require more resources to perform smoothly, which may be why we’re seeing the Ryzen infotainment system requirement.

This likely means that the new Dashcam Viewer won’t arrive on Intel vehicles in a future update unless Tesla can optimize the viewer enough to perform adequately on the older hardware.

HW3 vehicles already missed out on the new B-pillar recording feature. While Green thinks it’s technically possible to bring this feature to HW3 cars, unknown technical issues are likely preventing it. Older HW3 vehicles without a USB port in the glovebox only include USB 2 ports, limiting bandwidth, which could be one of the reasons, among others.

New Key Types

Perhaps a hint at Tesla’s third-party Robotaxi fleet ambitions, Tesla is building out new types of keys.

Rider Keys: These new keys appear to be designed to allow designated riders to access vehicles that are operating in “fleet mode.” This functionality sounds very much like what will be needed to allow Robotaxi customers to access a vehicle temporarily while they’re being given a ride.

Pre-Delivery Keys: Another new key type found is “pre-delivery.” While we don’t have an exact purpose nailed down quite yet, we’re assuming this could potentially allow new owners limited access to their vehicles for inspection prior to officially accepting delivery.

That’s plenty of interesting stuff found in the 2025 Spring Update - and we’re excited to see even more in just a few short weeks once Tesla launches their Robotaxi network in Austin.
