Tesla Rolls Out FSD V14.3.9 With Automatic Collision Evasion Feature
The new software update enables the vehicle to autonomously steer away from imminent collisions during manual driving.
Tesla has begun distributing software version 2026.27.6 to select vehicles, introducing a significant new safety capability known as Automatic Collision Evasion. The update also includes Full Self-Driving v14.3.9, which arrives with identical release notes to its predecessor but contains underlying refinements in behavior and performance.
What Happened
The rollout started recently and centers on the activation of Automatic Collision Evasion. According to the source, this feature is designed to "try to keep your vehicle safe and then continue driving" in specific scenarios while the driver is operating the car manually. The system engages if a frontal collision appears imminent and braking alone may not avoid it, or if the vehicle detects that the driver is insufficiently attentive to the road—such as reaching toward the back seat—or that Full Self-Driving (Supervised) may have been unintentionally disengaged.
Alongside the safety feature, the update delivers FSD v14.3.9. The release notes for this version are identical to the previous iteration, though early impressions from testers suggest the operation remains strong, with some noting that parking continues to be a challenge area. The core functionality of FSD remains consistent with current standards, described by testers as "really good" despite limited time to assess subtle differences.
Why It Matters
This update marks a notable shift in how Tesla’s autonomy stack interacts with manual driving. While many competitors like Hyundai, Kia, and Genesis utilize radar and camera sensors for autonomous emergency braking, Tesla’s new addition pioneers evasive steering intervention during manual driving modes. By allowing the vehicle to take over steering to avoid collisions when the driver is distracted or inattentive, the feature addresses a major safety concern: distracted driving. For owners, this adds a layer of passive safety that functions independently of whether Autopilot or FSD is actively engaged.
The Bottom Line
Tesla’s 2026.27.6 update brings Automatic Collision Evasion to a subset of owners, enhancing safety through autonomous steering interventions during manual driving. While FSD v14.3.9 offers no new feature notes, it includes performance refinements, positioning the software as a critical safety upgrade for the current fleet.
