Tesla FSD v14.3.4 Brings Smoother Driving and New UI Controls
Tesla releases FSD v14.3.4 for Hardware 4 vehicles, delivering smoother braking and new mid-trip controls. A lighter v14 version for older Hardware 3 cars is expected in late June 2026.
Tesla releases Full Self-Driving version 14.3.4 exclusively for Hardware 4 vehicles, marking a major step forward in driving comfort. The update eliminates the jerky, unnecessary braking that plagued earlier versions, replacing it with smooth, decisive maneuvers. Testers report that the system now handles merges, lane changes, and unprotected left turns with significantly less hesitation.
The latest software introduces helpful new user interface features, including a button to add a stop mid-trip and a pull-over option for destination arrivals. The system also shows superhuman awareness of pedestrians and cyclists, reacting with gentle, preemptive slowdowns instead of panic stops. Overall, users describe this as the most relaxing and competent version of FSD released to date.
Despite the impressive driving capabilities, the navigation and parking components still need further development to match the skill of the main driving module. Meanwhile, owners of older Hardware 3 vehicles wait for a pruned version called FSD v14 Lite. Tesla plans to release this optimized version for Hardware 3 cars by late June 2026.
