Tesla Rolls Out FSD V14.3.3 (Update 2026.14.6.6) With New FSD Features and Spring Update

Tesla has begun the long-anticipated merge of software branches across its fleet. Following a recent tease from its AI team that a unified update was imminent, the company has started deploying software version 2026.14.6.6, which includes Full Self-Driving (FSD) V14.3.3 and features from the 2026 Spring Update.

Instead of pairing the Spring 2026 Software Update with the existing FSD build, Tesla is rolling out a new FSD version. This release delivers the Spring feature set to vehicles on the latest self-driving branch and also brings FSD V14.3 to cars that already installed the Spring 2026 UI refresh.

Elon Musk commented on the rollout, stating simply that "FSD V14.3.3 is a ban”

The Spring 2026 Feature Drop

The update integrates the Spring 2026 software features that FSD beta users had been missing in recent weeks, with version 2026.14.6.6 now bridging that gap.

Vehicles receiving the update gain a new Self-Driving app that serves as a hub for subscriptions, step-by-step tutorials, and detailed telemetry profiles. The software also adds a native, hands-free "Hey Grok" wake word for xAI's assistant to manage personalized reminders, a reworked Pet Mode interface, and fully interactive navigation maps for the rear passenger screen. AMD-powered vehicles additionally receive new Unreal Engine-based park visualizations.

New Intervention-less Streak

Tesla is expanding real-time driving statistics in the new Self-Driving app, building on FSD V14.2, which introduced a dedicated "Self-Driving Stats" section to compare autonomous and manual miles.

The new streak indicator appears on the left side of the main display, above the speed limit sign.

Well this is new. FSD V14.3.3 has a live counter right on the main screen that shows how many miles you’ve driven on FSD since your last intervention.

With FSD V14.3.3, a widget on the left side of the main screen tracks uninterrupted FSD usage to the decimal and instantly resets to zero when the driver disengages. The Self-Driving app also permanently records your all-time longest intervention-free streak.

Actually Smart Summon Speed Increase

Actually Smart Summon (ASS) now has a higher top speed, moving up to 8 mph from 6 mph.

While a 2 mph boost may seem small, the 33% increase is noticeable in active parking lots, especially alongside Summon's near‑instant response time in FSD v14.3.2. This builds on FSD V14.3.2, which unified AI models across consumer FSD, Tesla's commercial Robotaxi network, and Summon. With reduced activation time and a higher speed ceiling, the car moves more confidently toward its owner, and many in the community are hoping for a 10 mph cap in a future point release.

FSD Disengagement Menu Changes

The post-intervention pop-up introduced with FSD V14.3.2 continues to be refined to be less intrusive while maintaining high-quality feedback.

With V14.3.3, the four on-screen options are restructured. The "Discomfort" and "Preference" categories have been removed in favor of clearer choices. Here's how the menu has evolved:

Bringing back the "Other" option is useful because the dialog still cannot be dismissed without a selection—aside from a voice‑recording workaround—so a catch‑all reduces the chance of choosing an inaccurate category and helps keep data unskewed. Overall, version 2026.14.6.6 serves as a more polished baseline as the rollout broadens.
