Tesla owners who have been patiently waiting to bridge the gap between the latest autonomous driving software and the vehicle's core user interface are about to get their wish. For the past month, a split has existed in the Tesla fleet. Owners on the mainstream branch have been enjoying the feature-packed Spring 2026 Software Update, while those on the cutting-edge Full Self-Driving (FSD) branch have been left without the latest features. It looks like that is finally about to change. When asked on X when FSD v14.3 would finally merge with the new Spring Update features, Kalena Brown, a member of Tesla's AI development team, responded simply with a GIF that said "Soon." This highly anticipated merge will not only give users currently on FSD v14.3 the latest cabin features from the spring release, but it will also give mainstream users already on the Spring 2026 Software Update access to the latest FSD build. The FSD version itself is expected to remain holding steady at 14.3.2. The Massive Spring 2026 Feature Drop Tesla’s Spring 2026 Software Update was exceptionally heavy on upgrades, essentially arriving on par with the company's major annual holiday releases. First rolling out under firmware version 2026.14 last month, it brings a host of new features and improvements to the cabin experience for supported vehicles. Among the standout features is a brand-new, dedicated Self-Driving app that consolidates your subscriptions, tutorials, and detailed usage stats into one clean dashboard. The update also introduces a native, hands-free "Hey Grok" wake word for xAI's in-car assistant, allowing for voice-activated, location-based reminders and more. Families and tech enthusiasts will also love the rebranded Pet Mode featuring 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.
