Tesla to Launch FSD v14.3 with Spring Update Features Soon

Tesla is preparing to merge Full Self-Driving (FSD) v14.3 with features from the Spring 2026 Software Update, closing the month-long split where mainstream vehicles enjoyed the spring release while cars on the FSD branch lacked those cabin upgrades.

Asked on X when the merge would happen, Kalena Brown from Tesla’s AI development team responded with a GIF that said "Soon." The combined release is expected to deliver the Spring 2026 cabin features to users already on FSD v14.3 and give mainstream users on the Spring 2026 Software Update access to the latest FSD build. The FSD version is expected to remain at 14.3.2.

The Massive Spring 2026 Feature Drop

The Spring 2026 Software Update, which first rolled out under firmware version 2026.14, arrived with a large set of enhancements to the in-cabin experience for supported vehicles.

Highlights include a new Self-Driving app that centralizes subscriptions, tutorials, and detailed usage statistics. The update also adds a native, hands-free "Hey Grok" wake word for xAI’s in-car assistant, enabling voice-activated, location-based reminders. Other additions include a rebranded Pet Mode with custom name and avatar options, interactive navigation maps for rear-seat passengers, and higher-quality studio-style parked visualizations for the new Model 3 and refreshed Model Y.

What FSD v14.3.2 Brings to the Table

FSD v14.3.2 delivers noticeable improvements in driving smoothness and confidence. A key architectural shift unifies core AI models across consumer FSD, Actually Smart Summon (ASS), and the Robotaxi platform, creating a more consistent performance profile and making Actually Smart Summon significantly faster and more practical in everyday parking lots.

The latest FSD v14.3 builds also add important safety and telemetry changes. If a driver ignores repeated attention warnings, the vehicle can now safely pull out of active traffic and park on a shoulder instead of stopping in the lane. In addition, Tesla has adjusted data collection with an updated FSD disengagement menu that effectively makes intervention feedback mandatory, keeping the prompt on screen until the driver specifies the reason for taking over.

Paving the Way for a Massive Fleet Expansion

Bringing the branches together streamlines Tesla’s codebase ahead of larger initiatives, such as the 10x parameter upgrade coming in FSD v15, and helps ensure cleaner data collection by aligning most of the fleet on the same software foundation.

Vehicles with HW3 and Intel Atom infotainment are receiving many Spring Update features, but self-driving enhancements will arrive later this summer when Tesla releases FSD v14 Lite. For HW4 vehicles, FSD v15 is slated for later this year and is expected to introduce a 10-billion-parameter neural network model. With a developer signal now hinting at a unified FSD v14.3 + Spring Update rollout, owners on both branches should watch for updates in the coming days.
