Tesla Rolls Out FSD V14.3.9 With Automatic Collision Evasion Feature
The new software update enables FSD to take over control during imminent frontal collisions or driver inattention.
Tesla has begun deploying software version 2026.27.6, which includes Full Self-Driving v14.3.9 and a new safety capability known as Automatic Collision Evasion. The rollout started recently, bringing significant changes to how the system interacts with drivers during critical driving scenarios.
What Happened
The 2026.27.6 update introduces Automatic Collision Evasion, a feature designed to activate Full Self-Driving under specific conditions. According to release notes, the system will attempt to keep the vehicle safe and continue driving if a frontal collision is imminent and braking alone may not avoid it. It also engages if the vehicle detects that the driver is not sufficiently attentive to the road, such as reaching toward the back seat, or if Full Self-Driving (Supervised) may have been unintentionally disengaged. Alongside this feature, Tesla is rolling out FSD v14.3.9, which shares identical release notes with the previous version but reportedly includes refinements in behavior and performance. A separate version, v14.2 Lite, is also being distributed.
Why It Matters
For Tesla owners, the addition of Automatic Collision Evasion represents a shift toward more active safety intervention during manual driving. By automatically engaging FSD when attention drifts or collision risks spike, the software aims to mitigate the dangers of distracted driving. Early reports from testers indicate that while general operation feels similar to previous versions, parking maneuvers remain a noted pain point. The update underscores Tesla’s strategy of enhancing vehicle safety and autonomy capabilities through over-the-air software improvements rather than hardware changes.
The Bottom Line
Tesla’s latest software update integrates FSD v14.3.9 and the new Automatic Collision Evasion feature, expanding the system’s ability to intervene during driver inattention or imminent collision scenarios. The rollout is currently reaching a subset of vehicles, with ongoing refinements to driving behavior and parking logic.
