Grok Voice Assistant Now Handles 119 Tesla Vehicle Commands

Tesla’s Grok voice assistant has expanded its functional scope significantly, now handling 119 out of 172 tested voice commands for vehicle controls, according to testing by Tesla owner @LifeMiddie. While the assistant has evolved from a simple chatbot to a comprehensive interface for climate, navigation, and settings, 53 commands still require the use of Tesla’s legacy voice system or manual touchscreen interaction.

What Happened

Grok’s integration into Tesla vehicles has progressed through several software updates, starting with its introduction in the U.S. via update 2025.26 as a conversational assistant. The 2025 Holiday Update added navigation capabilities, allowing drivers to describe destinations rather than reciting addresses. The Spring 2026 Update introduced the “Hey Grok” wake word and location-based reminders, while the Summer Update granted control over vehicle functions such as climate, seat heating, and various settings. Currently, Grok is available across North America, Europe, Australia, and most of Asia and the Middle East. To access these features, vehicles must have an AMD Ryzen infotainment computer and either Premium Connectivity or a Wi-Fi connection. The assistant is not available on older Intel Atom-powered vehicles, though update 2026.38 has quietly added Grok files to Intel Model 3 and Model Y cars, suggesting potential future compatibility. Users can activate the assistant by saying “Hey Grok” or, reportedly, “Hey Bro.”

The assistant now supports complex natural language queries for climate control, including specific temperature adjustments, fan speeds, and modes like Dog Mode, Camp Mode, and Bioweapon Defense Mode. It can also adjust seat heaters for the driver and front passenger, though it cannot control rear seat heating. Navigation commands allow for vague descriptions, such as “I’m hungry” or “Show nearby Superchargers,” and the ability to toggle route preferences like toll avoidance. Grok also manages calls, music playback across various services, and can open specific apps or websites to read content aloud. Chain commands are supported, enabling users to issue multiple instructions in a single sentence.

Why It Matters

The expansion of Grok’s capabilities marks a significant shift in how Tesla owners interact with their vehicles, reducing reliance on physical buttons and legacy voice commands. For drivers with AMD Ryzen hardware, the assistant now handles most routine tasks, including opening the glovebox, adjusting mirrors, toggling Sentry Mode, and navigating settings menus. However, the remaining 53 unsupported commands highlight ongoing gaps in the voice interface. Functions such as locking or unlocking doors, opening the trunk or frunk, adjusting air suspension ride height, changing display brightness, and muting navigation guidance still require manual intervention or the older voice system. This division in functionality creates a tiered user experience, where newer hardware owners enjoy a more seamless interface compared to those in older Intel-based vehicles, who may face delayed access to these features.

The Bottom Line

Grok now controls 119 of 172 tested vehicle functions, covering climate, navigation, media, and many settings. While features like hands-free text messaging and FSD controls are listed in the owner’s manual and discussed by CEO Elon Musk, they have not yet been deployed. Owners of Intel-based vehicles are currently excluded from the full assistant experience, though recent software changes suggest this may change in future updates.
