Tesla Software Update 2026.2.9.8: Release Notes

This update unifies the model used by Actually Smart Summon, FSD, and Robotaxi.

FSD (Supervised) v14.3.2

Requirements: HW4. Models: S, 3, X, Y, CT.

• The Reinforcement Learning (RL) stage used to train the FSD neural network has been upgraded, improving performance across a wide range of driving scenarios.
• The neural network vision encoder has been upgraded to better interpret rare and low-visibility situations, strengthen 3D geometry understanding, and broaden traffic sign recognition.
• The AI compiler and runtime were rebuilt with MLIR, delivering a 20% faster reaction time and speeding up model iteration.
• Reduced unnecessary lane biasing and minor tailgating.
• More decisive parking spot selection and maneuvering.
• Better prediction of the parking location pin, now shown on the map with a P icon.
• Enhanced behavior around emergency vehicles, school buses, right-of-way violators, and other uncommon vehicle types.
• Improved responses to small animals by emphasizing harder RL training examples and rewarding proactive safety.
• Improved traffic light handling at complex intersections involving compound lights, curved roads, and yellow light stopping, trained on hard RL examples sourced from the Tesla fleet.
• Better handling of unusual objects that extend, hang, or lean into the vehicle’s path by sourcing infrequent fleet events.
• Improved resilience to temporary system degradations by maintaining control and recovering automatically without driver input, reducing unnecessary disengagements.
• Unified the model between Actually Smart Summon, FSD, and Robotaxi for more capable and reliable behavior. (New in FSD v14.3.2, Not Available on Cybertruck)
• After taking over, you can help Tesla improve Self-Driving by selecting an intervention reason on the main screen. (New in FSD v14.3.2)

Upcoming Improvements

• Expand reasoning to all behaviors beyond destination handling.
• Add pothole avoidance.
• Increase driver monitoring sensitivity with better eye gaze tracking, improved handling of eyewear, and higher accuracy in varied lighting.

Note: This version adds a new bullet noting that the models for Actually Smart Summon, FSD, and Robotaxi are unified.

Full Self-Driving (Supervised)

Requirements: HW4. Models: S, 3, X, Y, CT.

With driver supervision, Full Self-Driving (Supervised) can operate the vehicle in most situations: it can start from a parked state, change lanes, choose forks to follow your navigation route, navigate around vehicles and obstacles, make left and right turns, and park at the destination. You and any authorized drivers must remain attentive and exercise additional caution. This feature does not make the vehicle autonomous. Do not become complacent.

Full Self-Driving (Supervised) is enabled on your vehicle. To activate it, press the Start Self-Driving button on the UI, or press the right scroll wheel button once. You can disable Full Self-Driving (Supervised) in Autopilot Settings.

Blind Spot Warning While Parked

Availability: Available worldwide on Cybertruck.

If you try to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind), the blind spot indicator light flashes, a chime sounds, and the door will not open on the first button press. Wait briefly and press the button a second time to override the warning.

Autopilot Name Changes

To align with naming updates, Tesla is replacing the term Autopilot with Self-Driving in most areas.

• Under Controls, the Autopilot tab has been renamed Self-Driving.
• Under the Autopilot menu, “Autopilot Features” has been renamed “Self-Driving Features.” This lets the user select between TACC, Autosteer, or Full Self-Driving.

Maps Version

Availability: Available worldwide.

The Software menu now shows only the map region and version (for example, NA-2025.44) instead of listing the region, version, and build.

Supercharger Site Maps Expanded

Availability: Available worldwide.

3D Supercharger Site maps introduced in the 2025 Holiday Update are expanding beyond the initial 18 U.S. locations to Europe, with at least two new sites in Belgium (Brugge and Heusden-Zolder).

These 3D site views pair an accurate layout with live data, showing stall positions, charger placement relative to parking spots, accessibility and trailer-friendly stalls, and more.

Live data indicates which stalls are occupied and identifies the Tesla model charging at each position. It’ll identify and display a 3D model of the vehicle, and for non-Tesla EVs, it’ll display a generic vehicle model.

While these 3D models are limited to vehicles with AMD Ryzen infotainment units, anyone can view them by searching for the location in maps.

Service Mode Improvements

Availability: Available worldwide.

ECU Update Status Panel Updates - Non-CAN ECUs Added

The ECU Update Status panel now includes non-Controller Area Network (CAN) Electronic Control Units (ECUs), such as the Autopilot processors and Telematics Control Unit (TCU).

Models: Model S (2021+), Model 3, Model X (2021+), Model Y, Cybertruck
