What Tesla Update 2025.20.6 Does
Tesla update 2025.20.6 is a software release for Tesla vehicles that includes bug fixes, performance improvements, and sometimes new features or interface changes. The exact contents vary depending on your vehicle model and region, since Tesla rolls out updates in phases rather than all at once.
Tesla does not publish a detailed changelog before release, so you will not know the specific changes until after you install the update or read owner reports on Tesla forums and social media. Some updates address known issues from the previous version; others add minor refinements to existing systems like the navigation, climate control, or autopilot behavior.
Key Takeaways
- Update 2025.20.6 installs automatically when your vehicle is plugged in and connected to WiFi, usually overnight, unless you have disabled automatic updates in your settings.
- You can check whether the update is available by going to Controls > Service > Software on your vehicle's touchscreen.
- The update typically takes 20 to 40 minutes to install, during which your vehicle will be unavailable to drive.
- If you want to delay the update, you can disable automatic updates in your vehicle settings, though Tesla may eventually require it for safety or security reasons.
- Backing up your vehicle's data before updating is not necessary — Tesla handles this on their servers — but you should may support your battery has sufficient charge.
How to Check for and Install the Update
To see whether update 2025.20.6 is available for your vehicle, sit in the driver's seat, touch the Tesla logo at the top left of the touchscreen, and select Controls. Then tap Service, then Software. The screen will show your current software version and whether an update is pending.
If the update is available and you want to install it right away, tap Install on that same screen. Your vehicle will begin the installation process when ready if you are parked and plugged in. If you are driving or the battery is low, Tesla will schedule the installation for the next time your vehicle is plugged in and idle.
During installation, your vehicle's systems will be offline. The touchscreen will go dark, and you will not be able to drive. Installation usually takes between 20 and 40 minutes, though it can occasionally take longer. Leave your vehicle plugged in and do not interrupt the process.
Automatic Updates vs. Manual Control
By default, Tesla vehicles read and install updates automatically when plugged in overnight. This means you may wake up to find that 2025.20.6 has already been installed without your action. If you prefer to control when updates happen, you can disable automatic updates in your vehicle settings.
To turn off automatic updates, go to Controls > Service > Power Off Updates and toggle it on. This will prevent your vehicle from installing updates while you sleep or while parked. However, Tesla may eventually push critical safety or security updates regardless of this setting, and you will receive a notification when that happens.
If you disable automatic updates, you will need to manually install new versions by going to the Software menu and tapping Install. Some owners prefer this approach to avoid surprises; others leave automatic updates on for convenience.
What to Do Before Installing
Before the update installs, make sure your vehicle is plugged in and has at least 20 percent battery charge. Updates require power, and if your battery drains during installation, the process may fail and require a service visit to recover.
You do not need to back up your data or settings. Tesla stores your vehicle configuration, saved addresses, and driving history on their servers, so your personal information will not be lost if something goes wrong during the update. Your vehicle will restore these settings automatically after the installation completes.
If you are concerned about a specific issue or want to know what changed in this version before installing, check Tesla owner forums, Reddit communities like r/Tesla, or Tesla's official social media accounts. Other owners often post summaries of changes within hours of a rollout.
Troubleshooting Installation Problems
If the update fails to install or your vehicle gets stuck during the process, the first step is to restart the vehicle. Press and hold both scroll wheels on the steering wheel until the Tesla logo appears on the touchscreen, then release. This performs a soft reboot and often clears temporary glitches.
If the update still will not install after a restart, check your WiFi connection. Your vehicle must be connected to a strong, stable WiFi signal to read and install updates. If your home WiFi is weak in your garage, try moving the vehicle closer to your router or connecting to a different network.
If you see an error message or the update repeatedly fails, contact Tesla Service through the Tesla app or by calling your local service center. They can diagnose whether the issue is with your vehicle's hardware or a temporary problem with the update rollout in your region.
What Happens After Installation
Once the update finishes, your vehicle will restart and return to normal operation. You may notice that the touchscreen layout, menu options, or certain features behave slightly differently. This is normal — take a few minutes to familiarize yourself with any changes.
If you notice a problem after updating, such as a feature not working as expected or an unusual warning message, restart your vehicle again using the scroll wheel method. Many minor issues resolve after a reboot. If the problem persists, note the exact behavior and contact Tesla Service with details.
