Tesla has emailed Model Y L owners in Australia to say Full Self-Driving (Supervised) v14 will not activate on their cars yet, despite the software already rolling out across the rest of the Hardware 4 fleet.
The email, sent to owners this week, says Australia is the first market anywhere to bring FSD v14 to the Model Y L. Tesla says that status means the model needs extra refinement and real world data before the company extends activation more broadly.
What Tesla told owners
Tesla's message says FSD (Supervised) v14 has begun rolling out across Australia and New Zealand more broadly, but the Model Y L is being held back as a specific case. Because no other market has had v14 on this model before, Tesla says it needs more development time to validate the software for it.
The company says it is treating the work as a priority and is actively working to progress the Model Y L as quickly as possible. Tesla has not given owners a release date, but says activation will follow once this validation phase is complete and that affected owners will be notified when the update is ready to install.
Part of a broader v14 rollout
The delay sits within a larger rollout. Tesla confirmed on 19 June 2026 that FSD Supervised v14 is now active across Hardware 4 vehicles in Australia and New Zealand, the first time the region has reached the same major software branch as North America. The build is v14.3.3, delivered through vehicle software update 2026.16.6.
Tesla launched FSD Supervised in Australia in September 2025 for Model Y and Model 3 vehicles fitted with Hardware 4 cameras. It was initially priced at $10,100 outright before switching to a $149 per month subscription.
The jump from v13 to v14 is a major version change. Tesla says it includes improved driver monitoring system sensitivity, an upgraded reinforcement learning stage for the FSD neural network, and a rewritten AI compiler.
Hardware 3 vehicles are not part of this rollout. Tesla is separately developing a v14 Lite build for older hardware, with no confirmed release date for Australia.
Why the Model Y L is different
The Model Y L is a six seat, long wheelbase variant Tesla launched in Australia in March 2026. Because it is a newer and structurally different vehicle to the standard Model Y, Tesla treats its FSD validation as a separate process, even though it shares the same Hardware 4 sensor suite.
Australia being the first market to attempt v14 on this specific model means there is no existing overseas data set Tesla can draw on. That is the reason given for the delay, though Tesla has not detailed what specific testing remains or how long it is expected to take.
What Model Y L owners can do now
Owners affected by the delay do not need to do anything. Tesla says the update will arrive automatically once validation is complete, with no indication owners can request early access or opt in ahead of the broader rollout.
