Tesla releases Full Self-Driving updates on a rolling schedule, not on fixed dates
Tesla's Full Self-Driving (FSD) system receives updates through the same over-the-air delivery method that handles regular vehicle software. Unlike traditional car manufacturers that announce update schedules months in advance, Tesla pushes FSD changes to vehicles as they become ready — sometimes weekly, sometimes with longer gaps. The company does not publish a master calendar of upcoming features or changes.
Updates arrive automatically to your vehicle when it is connected to WiFi and parked, or you can manually check for them through the vehicle's touchscreen. Tesla typically notifies owners through the in-vehicle display when a new version is available, and the read and installation happen without requiring a trip to a service center.
The pace and scope of FSD updates depend on Tesla's internal testing and the specific version track your vehicle is enrolled in. Some owners receive beta versions earlier than others, while some receive only the stable release versions that have been tested more widely.
Key Takeaways
- Tesla FSD updates arrive over-the-air without a fixed schedule, and you can check for them manually through your vehicle's touchscreen settings.
- Each update changes how the system handles specific driving tasks — lane changes, intersections, parking, or navigation — rather than overhauling the entire system at once.
- Beta versions reach some owners first and may include features not yet available to all FSD subscribers, but they also carry higher risk of unexpected behavior.
- You can decline an update and stay on your current version, though Tesla may eventually require you to update to continue using FSD.
- Update notes from Tesla are often brief and do not always explain what changed or why, so owners frequently learn about changes through community forums and YouTube channels.
What actually changes in each FSD update
Each Tesla FSD update typically targets specific driving scenarios rather than rewriting the entire system. A single update might improve how the vehicle handles unprotected left turns, while another focuses on parking lot navigation or highway merging. Tesla's release notes usually list these changes in one or two sentences per feature, without explaining the underlying technical changes.
Common areas that receive updates include intersection handling (how the car decides when to proceed through a light or stop sign), lane-change logic (when and how aggressively the vehicle changes lanes), and object recognition (how well the system identifies pedestrians, cyclists, or obstacles). Parking updates often address parallel parking, perpendicular parking, or summon features that let the vehicle move itself in parking lots.
The frequency of updates to any single feature varies widely. Some capabilities may receive refinements in consecutive weekly updates, while others go months without change. Tesla does not announce which features will be addressed in upcoming releases.
Beta versions versus stable releases
Tesla offers FSD through two main tracks: the standard release, which reaches all subscribers, and the beta program, which is limited to owners who have opted in and meet Tesla's criteria. Beta versions typically arrive one to four weeks before the same code reaches standard users, giving Tesla time to monitor real-world performance and collect data on edge cases.
Beta versions carry a higher risk of unexpected behavior — the system might make unusual decisions at intersections, hesitate longer than normal, or handle a specific scenario differently than previous versions. Tesla's beta program includes a disclaimer that the system may do things the driver does not expect and that the driver must remain attentive and ready to take control.
Opting into beta is a choice you make through your vehicle's settings, and you can switch back to the standard release at any time. However, once you switch back, you typically cannot rejoin the beta program when ready — Tesla enforces a waiting period before allowing re-enrollment.
How to check for and install FSD updates
To check for updates manually, open the Controls menu on your vehicle's touchscreen, select Software, and look for an option to check for updates. If an update is available, you will see the version number and sometimes a brief description of changes. The system will show you how much time the installation will take, usually between 20 and 45 minutes depending on the update size.
Updates read and install while the vehicle is parked and connected to WiFi. You do not need to be present during the installation, though the vehicle will notify you when it is complete. If you are in the middle of using FSD when an update becomes available, you can defer the installation until later.
Some updates are mandatory — Tesla will eventually require all users to update to continue using FSD, though the company typically allows a grace period of several weeks. You can see your current FSD version number in the same Software menu, which is useful if you need to reference it when discussing issues with other owners or with Tesla support.
What to do if an update causes problems
If you notice that FSD behaves differently or unexpectedly after an update, the first step is to document what happened — note the specific scenario, the road conditions, and what the vehicle did. This information is useful both for your own records and if you decide to contact Tesla support.
Tesla collects telemetry data from all vehicles running FSD, so the company is often aware of issues before owners report them. However, reporting specific problems through the vehicle's built-in feedback feature or through Tesla's support channels can help prioritize fixes. You can also downgrade to the previous version if the current update is causing significant problems, though this requires contacting Tesla support rather than doing it yourself through the vehicle menu.
Many owners discuss FSD behavior changes in online communities and forums, which can help you determine whether an issue is widespread or specific to your vehicle. These communities often identify patterns in how updates affect different road types or driving scenarios before Tesla acknowledges them officially.
Understanding FSD version numbers and what they mean
Tesla's FSD version numbers follow a pattern like 12.3.1 or 2024.50.15, where each number represents different levels of change. The first number typically indicates a major version, the second represents a minor update or release cycle, and the third shows a patch or bug fix. However, Tesla's versioning scheme has changed multiple times, so older vehicles may use a different format than newer ones.
A jump from version 12.3 to 12.4 usually indicates a more significant update than a jump from 12.3.1 to 12.3.2. However, Tesla does not publish a formal guide to what each version number means, so owners often infer the significance of an update based on the release notes or observed changes in behavior.
Knowing your current version number is useful when discussing FSD behavior with other owners, since the same issue might affect version 12.3 but not 12.4. It is also relevant if you are troubleshooting a specific problem, as Tesla support may ask what version you are running.
Why Tesla does not publish a detailed update schedule
Tesla's approach to FSD updates differs from traditional software releases because the company treats FSD as a continuously evolving system rather than a product with discrete versions. Each update is based on data collected from thousands of vehicles, and the timing of releases depends on when Tesla's engineers believe the changes are ready for broader deployment.
Publishing a detailed schedule would require Tesla to commit to specific features or improvements on specific dates, which conflicts with how the company develops and tests FSD. Instead, Tesla communicates through brief release notes after updates are already live, and through occasional announcements about major milestones or capability additions.
This approach means owners cannot plan around FSD updates the way they might plan around a phone operating system update. Updates can arrive at any time, and the changes are sometimes not obvious until you use the system after the update.
Frequently Asked Questions
Can I refuse an FSD update and keep using the old version?
You can defer an update for a period of time by not installing it when prompted, but Tesla eventually makes updates mandatory. The grace period typically lasts several weeks, giving you time to decide whether to update. Once the important date passes, you will not be able to use FSD until you install the current version.
Do I need to do anything to get FSD updates, or do they come automatically?
Updates read and install automatically when your vehicle is parked and connected to WiFi. You do not need to take any action, though you can manually check for updates through the vehicle's touchscreen if you want to install one sooner. You will receive a notification when an update is ready.
What happens if I am using FSD when an update is released?
If you are actively using FSD when an update becomes available, the system will not interrupt you. The update will wait until the vehicle is parked and you have finished using FSD. You can then install it at your convenience or defer it until later.
How do I know what changed in an FSD update?
Tesla publishes brief release notes on the vehicle's touchscreen when an update is available, usually listing the main changes in a few sentences. For more detailed information, many owners look to community forums, YouTube channels, and Tesla enthusiast websites that analyze and discuss each update's effects on real-world driving.
Can I go back to a previous FSD version if I do not like the new one?
Downgrading to a previous version is not something you can do yourself through the vehicle menu. You would need to contact Tesla support to request a downgrade, and the company may or may not honor the request depending on the circumstances. In most cases, Tesla encourages users to adapt to the new version rather than reverting.
