Reboot after an update
Lot's of people have random issues after a software install, many of them curing themselves after a reboot. As a general rule, we'd suggest always doing a scroll wheel reboot after a software update, simply press the two steering wheel scroll wheels until the screen turns off and then let go. The screen will come back within a minute or so, depending on hardware. It's certainly worth doing this is you notice any unusual behaviour, but prevention is better than cure. There's a second reset option which is to change the car configuration slightly, either the language, or wheel type. This also causes the car to do a soft reset and this has returned missing features such as Tidal. Our Guide to rebooting your Tesla provides more details.
How to get the latest Tesla Software Update?
In a word, you can't really force it yourself although you can help the car to download the update once it's been allocated to have an update. To do so, connect the car to WiFi, and maybe even consider a wireless hotspot when in use. Car's not connected to WiFi generally do not receive updates quickly.
If you visit the software screen and see the car hasn't checked for a few days, perform a scroll wheel reset. The car typically checks as soon as it reboots and we've had a software update immediately afterwards as a result.
You may find the car sticks at 50% for a while. We've seen reports that keeping the car awake will help speed past past this point as the car will try and sleep and halt the process. Even keeping the mobile phone app open may help to prevent the car sleeping.
Why do I not get some of the features or changes mentioned?
There are a number of reasons why a particular feature or change may not be included when your car upgrades. These include regional restrictions, hardware specific features, model specific updates and some changes are linked to software options purchased such as EAP or FSD. There are also times when software release notes are provided but only Tesla test engineers get the updates.
Not having a listed feature or update for a particular car is therefore quite normal. Some websites try to detail which cars get which features but this is often inaccurate, such as the blended braking update that came out with 2022.16 and the alternate routes option in 2022.28.
Against each release note we now list the car models and countries where a particular release note has been seen.
I thought I already had a listed feature?
Just as a feature may not land in every car, the feature may be mentioned in later releases when your car already has it. The release notes in the car are tuned to your car so, and while in general the car will only report a new feature once, that is not a rule that always holds true. Some websites say the feature is not available in your country whereas the reality is the feature has been there for some time
I'm on the FSD City Streets Beta
The FSD City Streets Beta is usually 2 to 3 releases behind the general software releases. This is normal.
Numbering convention
Release notes are numbered roughly using the a year.family.major.minor format. The year is self explanatory, the family release typically increments in 4's and is roughly the week of the year when the release family is launched, although these tend to slip over the course of the year. The major and minor release numbers of much debated, we personally believe these rarely contain new features not included in the family, and if there are differences it is linked to hardware specific versions.
When reviewing release notes, you may be interested in how a feature has evolved. To enable this we have also included a keyword search where you can search for a word or phrase and we will filter the results accordingly.
