Tesla is pushing FSD (Supervised) updates on two fronts simultaneously this morning. In North America, v14.3.3 paired with software build 2026.14.6.7 is now reaching its fourth wave of owners — and fleet data already shows it's the majority version on the road. In Europe, a separate but equally significant update just landed: version 2026.17.5 carrying FSD v14.2.2.6, starting in the Netherlands, which finally merges the FSD and Spring Update branches into a single install.
What Changed
| Change | Type | Region |
|---|---|---|
| Improved driver monitoring — better eye gaze tracking, eyewear handling, higher accuracy in variable lighting | Official | Global (v14.3.3) |
| FSD and Spring Update 2026.14+ branches merged into one install | Official | Europe (2026.17.5) |
| FSD subscribers gain access to Spring Update 2026.14+ features | Official | Europe (2026.17.5) |
The EU Branch Merge — Why It Matters
European Tesla owners who subscribed to FSD have been running a separate software branch from those on the Spring 2026 Update, meaning they missed out on features that rolled out in 2026.14+. Version 2026.17.5 closes that gap. Starting with the Netherlands — which secured type-approval for FSD back in April 2026 — this unified build gives EU FSD subscribers the same feature set their counterparts in the US, Canada, and other approved markets have been using.
According to background research, Germany, Norway, Estonia, and Lithuania have all received FSD approval in the past few weeks, with Tesla aiming for a coordinated EU-wide rollout by summer 2026. The Netherlands approval is being used as a regulatory template for the remaining countries. As of early June, 12 countries including the UK, France, Spain, and Portugal are still pending regulatory sign-off.
Fleet Adoption Is Moving Fast
The pace of the v14.3.3 rollout is notable. According to Whole Mars Catalog, data from @fsd_database shows a majority of Teslas tracked in that database are already running FSD 14.3.3 — and the 4th batch only just started pushing.
Elon Musk weighed in shortly after the rollout news broke, posting a simple nudge to owners:
Action Plan for Owners
If you're in the US, Canada, or other approved non-EU markets:
- Go to Controls → Software and tap Check for Updates. If you're in the 4th batch, 2026.14.6.7 with FSD v14.3.3 should appear.
- After installing, test the updated driver monitoring system — particularly if you wear glasses or drive in low-light or high-contrast conditions. The release notes specifically call out improvements in those scenarios.
- If you haven't received it yet, check back in a few hours. Batch rollouts typically complete within 24–48 hours.
If you're in the Netherlands (or another EU country with FSD approval):
- Check for 2026.17.5 under Controls → Software. This is the first wave, so availability will expand over the coming days.
- Once installed, FSD subscribers should now see Spring Update 2026.14+ features that were previously unavailable on the FSD branch.
- If you're in Germany, Norway, Estonia, or Lithuania — approval is in place, so this build should reach your region shortly as Tesla expands the rollout.
For owners in the UK, France, Spain, and other pending markets: regulatory approval is still outstanding as of early June. The EU rollout momentum suggests those approvals could come before summer's end, but no confirmed timeline is available yet. Keep an eye on our FSD coverage for updates as more countries go live.
