Tesla's own documentation has started describing something the car cannot yet do. The Model Y owner's manual, in the list of tasks the in-car assistant handles, now carries an entry for text messaging: "Ask Grok to send a text message to a contact or phone number (for example, 'Text Mom saying on my way')."
Ask Grok to do that today and nothing happens. Tesla has announced no feature and given no date.
This is not texting arriving in a Tesla
The obvious reading of this — Tesla adds text messaging — has the direction of change backwards. Teslas have sent and received texts by voice for years, through ordinary Bluetooth phone sync. Pair a handset running iOS 13 or Android 8.0 or later, switch on Sync Messages under Controls, and an incoming message shows the sender on screen, can be read aloud, and can be answered by voice with the right scroll wheel. Group replies remain unsupported on some phones.
What the manual documents is a change of which system does the writing. Today it is a fixed voice-command grammar that transcribes what you dictate. The manual's example is phrased as a request to Grok, which means a language model composing the message rather than transcribing it.
What the assistant already reaches
| Function | Scope in the manual |
|---|---|
| Navigation | route searches, destination management |
| Phone calls | placing calls |
| Media | search and playback |
| Vehicle controls | climate, seat and steering-wheel heating, glovebox |
| Controls panel | opening settings buried in menus |
| Vehicle questions | owner's-manual lookups |
Messaging would be the first item on that list that writes something on the owner's behalf and sends it to another person. Every other entry acts on the car.
Where European owners stand
Grok arrived with software update 2025.26 in the United States and reached nine European markets in the first quarter of 2026 on firmware 2026.2.6 — the UK, Ireland, Germany, Switzerland, Austria, Italy, France, Portugal and Spain. Since the Summer Update it has been running Grok Voice Think Fast 2.0, answering in about 0.70 seconds.
Two conditions still gate access, and nothing here changes either. The first is the AMD Ryzen infotainment computer, which rules out Intel-era Model S and Model X. The second is market availability, which Tesla has never published as a country list.
What to watch, and what not to read into it
A line in an owner's manual is a firmer signal than a leak, because Tesla writes the manual itself. It is still not a release note, and documentation has run ahead of shipping features before. Treat it as intent, not a date.
It is also a different thing from Grok Bot, the agentic version that would sign into external accounts. Sending a text is a single instruction, not a delegated task.
The practical question for a European owner is accuracy. A dictated reply fails visibly when it mishears, and you catch it. A composed one can be fluent, plausible and not quite what you meant — and it goes out under your name.
