Why Tesla doesn't update all of its vehicles at once

How to check for a software update

Not a Tesla App

Tesla releases a major update about once a month that includes feature improvements, safety enhancements or new features.

While some owners may receive an update within a few days of it being released, most owners will actually not receive the latest update for several weeks.

There are a couple of reasons why Tesla doesn't update all of its vehicles at the same time.

Unfortunately, updates for Teslas aren’t like mobile devices where an update is available for everyone right away. There’s a little more that goes into pushing updates for vehicles, especially for a vehicle that can drive itself.

How Tesla Rolls Out Updates

Tesla rolls out updates to its fleet based on the vehicle's VIN, region, model, hardware, and other factors. The main reason Tesla rolls out updates in this manner is to minimize risk and to assess how an update is performing.

Rolling out updates slowly lets Tesla quickly iterate on their update and focus on feedback and bug fixes before a potential issue has the chance to affect a large number of vehicles.

If, for example, an update caused the MCU reboot , making the display go dark while the vehicle was in motion, Tesla could more easily isolate the issue. Tesla would then be able to roll out a fix before the issue had a chance to affect a larger portion of their fleet.

Your vehicle model or other hardware in your vehicle is taken into account as well. For example, if Tesla is looking to gather feedback on a feature that requires MCU 2 or MCU 3, they may first send the update to those vehicles before releasing it more widely.

If you look at our software updates page you'll see that there are Tesla vehicles on a wide variety of updates. Some may be on the same major update, but on a different revision, while others may be one or two major updates 'behind'.

Although a vehicle can have an update that gets 'stuck' while downloading, that's usually relatively rare. If you notice that your vehicle falls too far behind, you can send a message to Tesla Service to see whether there is an issue with your vehicle.

What do the Numbers in Tesla Updates Mean?

Tesla's release process is why you may notice several versions for the same update.

For example, Tesla may first release update 2022.36, but as new issues are found and Tesla fixes them, Tesla will roll out further updates such as 2022.36.1 and 2022.36.2.

The 2022 in the version number stands for the year in which development began for this update. The 36 stands for the week number, and the last number stands for the revision of the update.

So in general, 2022.36.1 would include the same features as update 2022.36 but would contain several fixes for issues that were found in 2022.36, while 2022.36.2 would contain fixes that were fixed after 2022.36.1 was released.

This isn't always the case since Tesla does sometimes release new features with a minor revision, or but in general it's a good rule of thumb.

Once Tesla is confident they have solved all known issues, they'll then send out the update to the entire Tesla fleet.

Can I Force My Vehicle to Receive an Update?

Unfortunately, no. Under normal circumstances, there is no way to force your Tesla to receive an update. You'll simply have to wait until the update is available for your vehicle.

However, there are a couple of things you can do to receive updates as soon as possible.

It's not clear how much this toggle does anymore, but if you're interested in receiving updates as soon as they're available it's a good idea to toggle on “Advanced Updates” under the Software tab in your vehicle.

You'll also want to make sure your car is connected to Wi-Fi as often as possible, such as at home or work. Tesla prefers to download updates over Wi-Fi so this will ensure you get an update as soon as it's available to you.

You can track which updates are going out to by checking our software updates page.

How to Check if Your Tesla is Running the Latest Update

If an update is available for your Tesla, it will usually show up in your mobile app, although it's not clear how often the mobile app checks for updates. If you suspect an update may be available for your vehicle, you can check in your vehicle, although Tesla has recently started limiting this check to once per 24-hour period.

To check if there is an update available for your Tesla, tap Controls (the car icon), and then tap on Software. On the right side, you'll be able to check your vehicle's version and whether an update is available.

Your vehicle does not need to be connected to Wi-Fi to check whether an update is available

Do I Need to be on Wi-Fi?

For the most part, Tesla requires that updates be downloaded while the vehicle is connected to Wi-Fi.

However, there are exceptions to this. If an update includes important fixes or a recall then it is usually available over cellular. The same goes if you haven’t updated your vehicle in a while, are on FSD Beta, or other unique scenarios.

If you can't connect to Wi-Fi at home or work, you can try using public Wi-Fi networks or using your mobile phone as a hotspot for your vehicle.

Rivian to Add Google Cast and Native YouTube App, Will Tesla Respond?

May 17, 2024

By Not a Tesla App Staff

Coming to Rivian vehicles over a software update is Google Cast and YouTube support, which will allow for seamless, high-quality content streaming to Rivian vehicles.

This is a big step forward for Rivian’s software integration, especially compared to Tesla, which has yet to integrate native apps or release the long-rumored Tesla native app store.

Google Cast

Google Cast is Google’s version of Apple AirPlay which is supported in a variety of audio and video streaming apps such as Netflix, Disney+, YouTube, and more. By using a supported app, a user will be able to cast content directly to Rivian’s main 15.6” center screen.

Like Casting to a TV or Smart Device at home, this will allow you to play, pause, or skip back and forth using the vehicle’s touchscreen. Google Casting automatically pauses when the vehicle shifts into Drive.

Native YouTube App

Alongside Google Cast, Rivian is also bringing a native YouTube app to vehicles, enabling users to access YouTube’s video and music library from anywhere with a data connection. These features will be integrated right into Rivian’s vehicle operating system, which means they will receive regular software updates, and not be reliant on browser-based capabilities.

Similar to casting content, YouTube content will also automatically pause when the vehicle is shifted into Drive.

Tesla Equivalents

For the time being, there is no way to AirPlay or Cast video from a phone or tablet to Tesla’s front or rear screens. However, for some apps such as YouTube, you can send the video URL to the vehicle and have it open the YouTube app to that video.

To do this, open the YouTube app and find a video. Once you’d like to share it with the vehicle you can tap on share. You’ll then need to share it with the Tesla app which will then send it to your vehicle. On iPhones this requires you to scroll to the right and tap on More, which brings up the native sharing screen and has the Tesla app.

However, this is far more limited than including AirPlay or Google Cast support which will work for practically and video, even personal videos in your photo library.

Elon Musk mentioned back in 2016 that Tesla would add mirroring of phone apps to the center screen, but that has yet to materialize. More recently Musk mentioned a native X App coming to Tesla vehicles.

Tesla Theater

Tesla Theater allows users to stream videos from various platforms, including YouTube, but these are web-based applications, with no native applications available. This leaves some marked limitations on usability.

Tesla most recently announced in their 2024.14 update that the browser will be able to be expanded to full-screen mode when parked, enabling more access to streaming services on the web. Meanwhile, Google Cast and Apple Airplay continue to remain highly requested features.

Tesla FSD V12.4 - Features and Release Date

May 16, 2024

By Not a Tesla App Staff

The greatly anticipated FSD v12.4 is around the corner, with Elon Musk mentioning that it will be going to employees this weekend, with limited external testers next week.

Several significant improvements are coming with V12.4, which is being compared to the leap in performance that was previously seen between V12 and V11.

Improved Comfort and Reduced Interventions

There are quite a few improvements expected with V12.4, which Musk has said will be focused on user comfort by reducing hard accelerations and sudden braking. According to Musk, FSD v12.4 is also expected to have a 5-10x improvement in time between user interventions, which means that Tesla is rapidly approaching its goal for the Robotaxi announcement on August 8, 2024.

Steering Wheel Nag Removal

FSD V12.4 is expected to eliminate the steering wheel nag, as Musk confirmed its removal last week. The camera-based driver monitoring system will be taking over, providing a hands-free experience. These improvements will most likely benefit owners who have cabin cameras with infrared lights the most, while Tesla may continue to use steering wheel nag as a fallback mechanism.

Driverless Autopark

The second key feature that may be included in v12.4 will be Banish Autopark, previously known as Reverse Summon, allowing you to choose a parking spot, exit the vehicle and have the car park itself. Whether this feature makes it in v12.4 is yet to be seen, but Musk has mentioned that parking without a driver is coming soon.

Automatically Seek Parking Spot at Destination

Finally, your Tesla will now traverse a parking lot and automatically enter Autopark mode when arriving at a destination, according to a post from Musk.

Eligibility and Branch

Tesla recently added FSD v12.3.6 to the 2024.14 branch with updates 2024.14.5 and 2024.14.6. This makes it very likely that Tesla’s next FSD version will also be based on 2024.14, meaning that it will be available to any vehicle on 2024.14.x.

For users on update 2024.3.25, this means that they’ll receive all of the features included in updates 2024.8 and 2024.14, which should make it a massive update.

Release Date

Musk has mentioned that FSD V12.4 is going out to employee vehicles for internal testing this weekend, with external testing starting next week. The rollouts typically go slower than predicted but looks like we may see this begin shipping to customers by the end of the month.
