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 is getting ready to introduce WiFi garage door support to their vehicles through MyQ.
Since our article yesterday additional details have emerged about how MyQ will operate, which vehicles will be supported and whether there will be a cost to use the service. This information is based on a page that appeared briefly on MyQ's website but has since been removed.
MyQ's website stated that support for their garage door openers would be coming to the Model 3 and Model Y. While this makes a lot of sense because those vehicles don't include a HomeLink module, we'd be surprised if Tesla didn't also add support for the Model S and Model X.
Let's get cost out of the way. Although MyQ does not charge a fee today to remotely open and close their garage doors, they do plan on charging a fee to use their devices in vehicles. This could be looked at similarly to how some services are free to use on a PC but require a subscription to use on your mobile phone.
The price posted on MyQ's website was a five-year plan for $179, which is still cheaper than Tesla's $350 installation cost for HomeLink.
Unfortunately, this removes a big benefit we thought MyQ would have over buying a HomeLink module for the Model 3 or Model Y. For Model S and Model X owners who already have HomeLink included in their vehicles, it may not make as much sense.
However, MyQ does provide some advantages over HomeLink.
The good news is that MyQ integration will be very similar to HomeLink, and better in some ways. What appears to be a rendering of the feature working in a Tesla was also posted to their website which shows off a screen very similar to HomeLink.
On the MyQ settings screen, you'll have a list of supported devices on the left side, such as garage doors, gates and possibly lights, but we haven't see any evidence of the latter yet.
On the right side, you'll see options pertaining to the device selected, such as its current state, whether the garage door should auto-open or close and the distance when the device should be triggered.
You'll also be able to have the vehicle fold in its mirrors when reaching the target location.
If you've used HomeLink, this should all look very familiar since it's almost exactly the same. However, there are a couple of differences that give the advantage to MyQ.
The first is that MyQ is a smarter system and it knows the state of your garage door. So if you're arriving home and the garage door is already open, it won't try to close it on you.
The other advantage is distance. Since MyQ works over the internet you'll be able to trigger the garage door or gate from further down the driveway, giving the door plenty of time to fully open before you arrive.
MyQ supports an array of devices, but it waits to be seen whether there will be support for these additional devices such as lights and door locks.
Tesla requested more time for details to be kept confidential, and in doing so, everyone now knows something is up. A document dated November 18, 2022, appeared on Twitter on December 6. It’s from Tesla Inc. and addressed to the Federal Communications Commission. In the brief letter, Certification Engineer Cindy Li requests a 60-day extension of a previous agreement to keep a device secret. This mysterious letter set the Tesla sphere on fire with speculation to find out what is the secret device.
All we know from the letter is that model number 1541584 includes a user manual, internal photos, external photos, and test setup photos. Whatever this device is, it was going to be made public by the FCC on December 7, 2022. Tesla asked for an extension because the device will not be ready until mid-January 2023. The company wants to “avoid any unnecessary disclosure and competitive harm before our product launch…”
The poster of the letter, Twitter user @Taka87 reached out to well-known Tesla hacker @greentheonly, for some insight. The response: … something potentially major planned for mid-January which is just a bit over a month away... Like something that coincides with a sensor suite change.
That opens the door for the return of radar, which was removed last year and/or ultrasonic sensors, which Tesla just scrapped in October when it made the call to go completely with Tesla Vision. At that time, Tesla said in a statement: With today's software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and the ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.
There has also been a lot of speculation about HW4, where a high-resolution radar is believed to be part of the full self-driving sensor suite. HW4 goes as far back as the 2021 A.I. Day when Elon Musk said a new FSD computer would come out with the Cybertruck. This upgrade is now reportedly being developed by the Taiwan Semiconductor Manufacturing Company Limited (TSMC). It is expected to be much more powerful than the current hardware by as much as four times.
Elon has also previously commented on HD radar, saying "A very high-resolution radar would be better than pure vision, but such a radar does not exist. I mean vision with high-res radar would be better than pure vision."
An unidentified part, closely resembling a new radar was found on Tesla's Parts Catalog back in September by @GreenTheOnly. This mysterious item was marked but suspiciously not given a name, a part number or a description. However, given Green's experience with the inner workings of these vehicles, Green believes it is a new Tesla radar. In a follow-up tweet, he doubled down on his stance, saying the part matches the high-resolution radar Tesla registered with the U.S. Federal Communications Commission in June.
