Tesla Announces 2026 Summer Update with Expanded Grok Controls and Route Memory

Tesla has announced its 2026 summer software update (version 2026.26), which expands the Grok AI voice assistant's vehicle control capabilities and rolls it out across Europe. The update also introduces features like custom wrap uploads via the mobile app, destination charge settings, and route preference memory. This update enhances the in-car user experience by integrating advanced AI voice controls more deeply into daily vehicle operations and expanding Tesla's software ecosystem in Europe. It also reflects Tesla's ongoing transition toward software-defined vehicles where personalization and convenience are continuously updated over-the-air. Grok can now control functions like making calls, playing music, and opening the glovebox, while the navigation system will prioritize historically preferred routes unless a significantly faster alternative exists. Additionally, the update enables screen-based seat adjustments for all models and introduces a rear screen lock for parental control.
