Tesla FSD v14.3.11 starts reaching US cars with update 2026.33.5: Automatic Collision Evasion and home backup through Powerwall
The new FSD (Supervised) build has the same notes as v14.3.10 but moves to the 2026.33 software branch. The update includes the feature that can engage FSD when the driver isn't paying attention, plus Vehicle-to-Home with Powerwall. The first installs are all in the US.
Tesla has started pushing update 2026.33.5, which brings FSD (Supervised) v14.3.11. The rollout is only just beginning: this morning TeslaFi counted two cars on the new version and Teslascope four installs, all in the US.
What's new in FSD v14.3.11
On paper, almost nothing: the notes are identical to v14.3.10. What changes is that FSD moves to the newer 2026.33 software branch, after previous builds shipped on 2026.27. The list of improvements is the familiar one: an upgraded RL training stage, an AI compiler rewritten with MLIR for 20% faster reaction time, better responses to emergency vehicles, school buses and small animals, and more accurate driver eye-gaze monitoring. Actually Smart Summon now goes up to 13 km/h (8 mph), and pothole avoidance is listed under "upcoming improvements."
Automatic Collision Evasion
The feature is available on HW4 cars: Model 3, Model Y, the new Model S and X, and Cybertruck. According to Tesla's notes, Automatic Collision Evasion activates FSD (Supervised) to try to keep the car safe and then continue driving. It can step in while you're driving manually and the car detects that you're not sufficiently attentive to the road (for example, reaching toward the back seat), or that FSD may have been disengaged unintentionally. Some versions of the notes, as shown by Tessie, describe one more scenario: an imminent frontal collision that braking alone may not avoid.
The feature isn't new: it first appeared back in FSD v14.3.9.
The car backs up the house through Powerwall
The second item in the notes is Vehicle-to-Home with Powerwall. A parked car plugged into a compatible Wall Connector can extend your home's backup power during an outage, together with Powerwall. You turn it on under Charging > Powershare. The feature debuted on the Cybertruck in September, and since yesterday Tesla has offered it on Model 3 and Model Y too, in the US only and with a Powerwall 3.
Teslascope shows the same update also bringing FSD v14.3 Lite to some HW3 Model 3s in North America.
In Europe, FSD is legal in only eight countries, and 2026.33.5 hasn't been reported here yet. For where FSD v14 still slips up in everyday use, read the five problems flagged by an owner who drives 76% of his miles on FSD.
