The .300 point release is the version most owners received and the one generating the most search interest.

Grok AI in Tesla Vehicles

What Grok is: Grok is an AI assistant developed by xAI (Elon Musk's AI company). It is a large language model capable of answering questions, summarizing information, and accessing real-time information.

What Grok does in a Tesla: When you press the voice button and ask a question beyond standard commands, the query is now routed to Grok.

Examples:

"What's a good restaurant near my destination?"
"What's the weather going to be like for my whole trip?"
"Explain what that dashboard warning light means"

Eligibility: Model 3, Model Y, Model S, Model X with Premium Connectivity. Standard Connectivity vehicles receive a limited version.

Other 2025.26.300 Changes

Energy app redesign: The new layout shows current consumption vs. historical average, real-time breakdown of energy consumers, and a simplified "trip efficiency" score.

HomeLink expanded geofencing: Garage door triggers now support a larger geofence radius (configurable up to 500 feet vs. ~100 feet default).

Driver profile improvements:

Driver profiles now sync seat, mirror, and steering column position more reliably
A new "Guest" profile option creates a temporary, non-personalized profile

Resolved seat heater reset issue from 2025.20.6
