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.

Tesla Updates Hazard Lights Frequency To Improve Safety in Software Update

Tesla is rolling out a significant safety enhancement through a software update. Teslas, already the safest vehicles on the planet, got a little safer thanks to a small company based in Texas. While this article will highlight the advancement in safety, it will also applaud the work of Emergency Safety Solutions, which dared to challenge the old way of doing things.

Overnight Evolution: The Game Changer

Tesla North America didn't mince words when they announced: "If an airbag is deployed, hazard lights will automatically activate & flash faster to improve visibility." Elon Musk added, "New Tesla safety feature uploaded via over-the-air software update. Your car just got better while you slept."

It got much better thanks to a partnership with Emergency Safety Solutions (ESS), which we spotlighted a year ago. The small company, now just five years old, used a Tesla Model 3 to display its advancements in the hazard lights system, which had remained unchanged for more than 70 years. After numerous studies, the company changed everything about the hazard lights and approached Tesla with its findings.

Chilling Frequency: Every seven minutes, a disabled vehicle is involved in a crash on American roads. The result? An alarming 15,000 injuries or fatalities annually.

Ancient Flaws: The primary culprit behind these startling figures is a hazard light system that hasn't been updated in over seven decades.

The Solution: A frequency shift by adjusting flash frequencies from the sluggish 1.5Hz system to between 4Hz and 6Hz immensely heightens driver alertness. Hertz is a unit of frequency, which equals the number of cycles per second. In this case, the frequency of flashing lights is increased from 1.5 flashes per second, up to 4 - 6 flashes per second.

Real-World Outcomes: When 5Hz flash frequency was tested, drivers reacted a crucial 12 seconds faster. Moreover, they recognized an issue of more than three football fields sooner than the 70-year version. The number of drivers shifting to the safer side of a disabled vehicle also shot up dramatically — from 30% to an impressive 87%.

Emergency Safety Solutions also posted on X: "Great step toward making our roads safer for people in disabled and vulnerable vehicles! We appreciate our partnership with Tesla and applaud this major milestone in our mission to protect drivers when they need it most."

Software Update

Tesla states in their post on X that this update is rolling out now in the U.S. to Model 3/Y vehicles and newer Model S and Xs.

It's not clear whether Tesla means this enhancement is available in update 2023.32, or whether it's in the upcoming 2023.38 update, which is currently in employee testing.

It's more likely that H.E.L.P. is implemented in update 2023.38, but we have yet to receive release notes for vehicles in the U.S., so we'll have to wait and see if this enhancement made it in.

More H.E.L.P. to Come

Keep an eye out for even more safety advancements courtesy of this partnership with ESS and Tesla. The company created the Hazard Enhanced Location Protocol or HELP. Beyond the lightning-fast flashes, HELP seamlessly integrates with in-car and phone navigation systems, giving drivers a heads-up about potential hazards before they become visible. It's like giving your Tesla a sixth sense.

Unfortunately, that will take longer as it would require more automakers to get on board with this new system. However, as we've realized, automakers are following Tesla's leadership on several fronts, and they may also increase road safety and implement the advanced system.

Video Reveals the Tesla Cybertruck's Unique User Interface [Video]

It's not a good day to be named Max and work at Tesla or on the security team assigned to the Cybertruck. You can't help but wonder how a daring individual found himself in the driver's seat of this highly anticipated vehicle. This perpetrator spoke in Russian and joked that a bag in the truck belonged to Elon Musk before zooming in to a name tag reading "Max."

While we certainly don't condone breaking the law, we were provided with a risky reveal of the Cybertruck's interior courtesy of a mysterious and perhaps too-bold-for-his-own-good infiltrator.

Cyber-Theme UI

The video is less than a minute long but provides new information, notably on the updated user interface (UI). For weeks we've had Cybertruck sightings, but this is our best look at the Cybertruck's display.

Updated Icons and Font

The UI appears designed specifically for the Cybertruck; icons possess subtle sharp edges, mirroring Cybertruck's angular aesthetics. This design philosophy also extends to the unique font choice, giving the UI a rugged, distinct look.


A further advancement is the seamless transition between vehicle visualization and maps. The once-clear partition is a fading background, allowing for a more unified appearance. This unity is further emphasized with the vehicle now being depicted atop a 3D polygon terrain, which has been discovered before in firmware updates.

Icon Placement Changes

One of the first distinctions users would notice is the transition from horizontal app icons. This design has been the hallmark of previous Tesla models, to a vertical arrangement along the lefthand side of the screen.

The vehicle control icon is at the bottom, followed by climate controls and other apps. The gear indicator has evolved, too, switching from its usual horizontal layout to a vertical orientation in the screen's top left portion.

The status icons, such as time, temperature, Tesla profile used to grace the top of the display, but they have now been realigned to the left side and can now be found directly above the vehicle visualization.

Cameras, Front Camera Confirmed

Another intriguing update revolves around the Camera app. Where previously users had to decipher camera views, they are now labeled for convenience, as showcased in the video with marked "Left" and "Front" camera views. Yes, there is a front camera view, finally answering the question of Tesla introducing the front bumper camera. We previously had a look at how we expect Tesla's updated Camera app to work with the front bumper camera.

Battery Icon

One of the standout features in the video is the battery display. Gone are the traditional battery icons. Instead, we are introduced to slanted lines, each symbolizing 10% of the battery charge. This visual representation is intuitive and integrates with the Cybertruck's angular design.

Music Mini Player?

Beneath the vehicle visualization is what appears to be a minuscule music control feature, though its precise functionality remains uncertain from the short video clip.

Inside the Cybertruck: More than Just a Fresh UI

Ambient Lighting: Drawing inspiration from the latest Model 3 Refresh and the Chinese Model Y, the Cybertruck incorporates a colorful ambient lighting strip. Strategically placed, this lighting adds a modern aura to the vehicle's groundbreaking design.

Interior Layout and Accessories: The video takes us on a mini-tour of the truck's interior, revealing several intriguing features:

Hexagonal Design Elements: Keeping in line with Cybertruck's geometric aesthetic, the backup camera icon flaunts a hexagonal design, intriguingly contrasting the octagonal design found on the cupholders.

Center Console: A spacious tray area reminiscent of the old Model S finds a home between the front seats. Decked with some wires and a yet-to-be-identified document, the console boasts "cyber cupholders" with an octagonal design. Furthermore, it's equipped with dual phone charging spots right in front of the cupholders.

Sun Visor: The video briefly showcases the two-stage sun visor, which resembles the one found in the Model X. The video provides a glimpse of the massive glass roof, promising a panoramic view that will undoubtedly make the interior feel even more expansive.

Rear Window View: A feature with many talking is the clear view through the back window. Although the video offers only a short glimpse, obstructed by tires placed in the truck's bed, it's evident that when the cover is open, drivers and passengers will benefit from an expansive, unobstructed view.

As one viewer pointed out, this video will probably be used for evidence one day. Whoever was in the Cybertruck owes Max an apology, and poor Max needs to remember to lock the door.
