Tesla began the rollout of FSD (Supervised) v14.3.3 on 17 May 2026, bundled inside firmware 2026.14.6.6. The build is going out to a small early-access slice of the fleet first — the NotATeslaApp tracker showed fleet penetration at 0% with only a handful of cars updated on day one — and is expected to widen over the coming weeks. It is the first 14.x point release to carry the full 2026 Spring Update feature payload alongside the latest FSD branch.
Live intervention-free streak counter
The headline FSD-side change is a live intervention-free streak counter. The Self-Driving App now shows the distance covered in FSD (Supervised) since the last intervention and tracks the user's longest streak, with the live counter resetting each time the driver takes over. It is the first time Tesla has surfaced this metric inside the in-car UI rather than only as a backend telemetry signal — and the first time it is exposed live during a drive rather than retrospectively after the fact.
Actually Smart Summon: shared backend, faster Summon
The second meaningful change is to Actually Smart Summon. Tesla has merged the backend AI model behind Smart Summon, FSD and Robotaxi into a single shared stack, which it says delivers more capable and reliable behaviour in low-speed parking-lot scenarios. The most visible consequence is a max-speed lift from 6 mph (10 km/h) to 8 mph (13 km/h) for the Summon feature.
FSD v14.3.3 is a point release on top of v14.3.2, which began wider rollout in late April with the redesigned post-disengagement menu and the first AI-model unification work. The 14.3.3 build does not change FSD's regulatory status — it is the same FSD (Supervised) feature set, only with new features layered on top.
Spring Update bundle
The 2026.14.6.6 train also carries the complete 2026 Spring Update feature set that earlier 2026.14.x firmwares had been delivering in stages. The official release notes list:
| Spring Update item | What it does |
|---|---|
| Pet Mode | Driver-side characters and expanded Pet Mode UI |
| Hey Grok | Voice activation for the Grok assistant |
| Sketchpad | In-car drawing app |
| Blind Spot Warning While Parked | Alerts when occupants open doors near traffic |
| Blind Spot Warning Accent Lights | Adds ambient-light cues to existing BSW |
| Chime When Light Is Green | Audible cue at traffic lights when driver is distracted |
| Live Camera View | In-app live look at the parked car's surroundings |
| Immersive Sound Upgrade | Re-tuned cabin audio profile |
| Trips, Music App Queuing | Trip statistics and music queue handling |
European owners: what to expect
European owners will receive the firmware payload (Spring Update features, UI changes, blind-spot enhancements) like the rest of the global fleet — these ride on the same 2026.14.6.6 carrier and do not depend on FSD regulatory status. The FSD (Supervised) v14.3.3 portion remains gated by regional approval: Tesla still cannot offer FSD (Supervised) as a hands-on/eyes-on feature in EU member states pending the relevant approvals, so the new streak counter and Summon backend will activate only for owners in markets where FSD is licensed.
The build covers both HW3 and HW4 vehicles on day one. Owners can track penetration on TeslaFi's firmware tracker, which is reporting 2026.14.6.6 across the fleet as the rollout widens beyond early access.
