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

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 Cybertruck to Receive Charging Improvements in Upcoming Update

Former Tesla VP of Powertrain and Energy Drew Baglino previously mentioned that Cybertruck would be receiving charging improvements soon.

Wes Morrill, Tesla’s Cybertruck lead engineer, recently reposted Baglino’s comments on the charge speed update on June 16th and mentioned that it would be coming soon via OTA.

Charging Improvements

The 4680 cell has seen some difficulties in its charge curve, similar to Tesla’s other vehicles that have been deployed with the 4680. Tesla has alluded to difficulties in the manufacturing curve previously, and also with engineering improvements to the new cell standard, and eventually stopped manufacturing the Model Y with the 4680 cells.

However, this is the first time that Tesla has begun to deploy major improvements to the 4680 cell. It appears the improvements will allow up to 154 miles to be recovered in 15 minutes, which is approximately a 30% improvement to current charge rates.

We’re hoping that these improvements to the 4680 will also translate to older Model Y vehicles that have 4680 cells, which will be key to the owners of these vehicles. 4680 production is currently mainly focused on Powerwall, Megapack, and Cybertruck – with Semi not using 4680 yet.

Tesla Model 3 Long Range Now Eligible for $7.5K Tax Credit

In the US, the Model 3 Long Range has now become fully eligible for the $7,500 federal tax credit for EVs.

Federal Tax Credit

The federal tax credit is up to $7,500 USD off at the point of sale, which applies to EVs with batteries originating from the United States. The Model 3 Performance was launched with the EV tax credit, which meant that until now, it was cheaper to purchase than the Model 3 Long Range.

Interestingly, after this change, the Model 3 Long Range is only $1,000 USD more expensive than the Model 3 Rear Wheel Drive, as the RWD model is not eligible for the credit. The LFP batteries in the RWD model are from CATL in China, and thus mark it as ineligible.

At $40,000 USD, the Model 3 Long Range is now an even better deal than before – and is nearly $7,500 less (the amount of the credit), than the average new car in the United States.

Canadian EV Credits

In Canada, Tesla dropped the Model 3 RWD price by $1,000 CAD, in response to the province of  British Colombia reducing the upper limit of their EV credit MSRP range. This means that the Model 3 RWD is the only Tesla vehicle that is covered under the new BC rebate – which is one of the few provincial rebates still left standing.

Sadly, as a result of this change, and due to a weird classification gimmick, the Model Y is considered a sedan by the Government of BC and is completely ineligible for the additional rebates – but the $5,000 federal EV rebate still applies.

Tesla vehicles accounted for 80% of federal EV rebate applications in Canada in 2023, marking a net increase since last year at 60%.
