Tesla's Grok AI Set to Send Text Messages From Your Car
Tesla is preparing to let its Grok AI assistant send text messages on behalf of drivers, a feature that appears in the latest owner's manuals for the Model 3 and Model Y. The capability is not yet active in vehicles, but its inclusion in official documentation suggests Tesla could enable it through a server-side switch or a future software update.
The move comes as part of Tesla's broader push to make Grok a central interface for vehicle controls. With the 2026 Summer Update, the AI assistant already handles navigation, climate adjustments, mirror folding, and even glovebox access through natural language commands. Adding text messaging would close a notable gap in the car's native messenger app, which has struggled with speech-to-text accuracy.
What Can Grok Do in Tesla Vehicles Now?
Currently, Grok can dial phone numbers or call contacts, set destinations, and control a range of vehicle functions. The assistant is also being positioned to start Full Self-Driving (FSD) sessions with voice commands, according to recent updates. Tesla CEO Elon Musk has hinted at deeper integration with external AI agents, potentially allowing drivers to delegate tasks while the car drives autonomously.
The manual reportedly instructs users to say phrases like Text Mom saying on my way, indicating the system will parse natural language to compose and send messages. This would represent a significant upgrade over the current voice-to-text functionality, which many drivers have found unreliable.
Why Is Tesla Adding This Feature Now?
Competition appears to be a driving factor. Rivian introduced its own agentic AI assistant, Rivian Assistant, which can log into third-party services, extract information, and book events using vehicle data as context. Tesla's Grok, by contrast, started as a simple chatbot with the 2025.26 update before expanding to navigation and location-based reminders.
The 2026 Summer Update (2026.26) marked a turning point, giving Grok the ability to replace traditional voice commands for many controls. Text messaging is the logical next step, and its presence in the manual suggests the infrastructure is already in place.
What Does This Mean for Drivers?
For Tesla owners, the feature could reduce distraction by letting drivers keep their hands on the wheel and eyes on the road while Grok handles communication. The integration with FSD could also enable a future where passengers assign tasks to AI agents during autonomous trips, turning the car into a mobile productivity hub.
No official timeline has been announced for the rollout. Tesla has a history of activating dormant features remotely, so the capability could appear without a major software release.
Frequently Asked Questions
Can I use Grok to send text messages in my Tesla right now?
No. The feature is listed in the latest Model 3 and Model Y owner's manuals but is not yet active in vehicles. Tesla may enable it via a server-side switch or a future software update.
What other tasks can Grok perform in Tesla vehicles?
Grok can currently set navigation destinations, adjust climate controls, fold mirrors, open the glovebox, dial phone numbers, and start FSD sessions with voice commands.
How does Grok compare to Rivian's AI assistant?
Rivian Assistant can log into third-party services, extract information, and book events. Grok is catching up with natural language controls and messaging, but Rivian currently offers more agentic capabilities.
