Tesla is rolling out its 2026 Summer Update, software build 2026.26, with the biggest changes centered on the in-car Grok voice assistant and navigation. The update is rolling out in waves and is expected to reach most vehicles by the end of July 2026, according to Not a Tesla App, which tracks official release notes.
Grok, the AI assistant Tesla introduced in 2025 as a chat feature, now handles real vehicle controls. You can ask it to place phone calls, search for and play specific songs, adjust the cabin temperature, or open the glovebox, all by voice, in addition to the navigation requests it already supported. Tesla says Grok is also expanding beyond the US, with Europe and parts of Asia next in line.
Navigation gets smarter, too. Automatic Navigation already routed you home, to work, or to calendar events. With this update, it learns other places you go regularly, like a school drop-off on the way to work, and starts suggesting routes to them without you typing an address. It also starts favoring roads you’ve actually driven before over whatever route is technically fastest.
What else is in the update
- Self-driving stats in the app. If your car has FSD, a new section in the Tesla app shows your usage statistics, with an option to share them.
- Vehicle wrap uploads. Owners with supported vehicles can upload a custom wrap design directly from the Tesla app instead of transferring files by USB.
- Caraoke scoring. The in-car Caraoke feature now scores your performance while parked and saves high scores to your driver profile.
- Supercharger search by name and the ability to add Apple Music tracks to your queue.
None of this requires you to do anything. Updates install over the air, and Tesla typically notifies you in the app and on the car’s touchscreen when 2026.26 is ready to install on your specific vehicle. If you want to check now, look under Software in your car’s touchscreen settings, or the Software Update section of the Tesla app.
As with past over-the-air updates, exact rollout timing varies by region, hardware, and vehicle configuration, so don’t be surprised if a neighbor with the same model gets it a few days before or after you do.
