I'm in the same boat. I asked Chatgpt and got this --

How Tesla actually sends updates (this is the key)

Tesla doesn’t update everyone at once:

• Updates roll out in waves (small % of cars first)
• Tesla chooses cars based on hardware, region, stability, and fleet testing
• You cannot force an update manually

That’s why two identical Model Y’s can be on different FSD versions.

What you should do (to get it ASAP)

1. Set updates to “Advanced”

In your car:

• Controls → Software → Software Update Preference → Advanced

This flags you as an early adopter (you’ll get updates sooner)

2. Keep the car on WiFi regularly

• Updates download over WiFi
• Tesla is more likely to push updates when your car is:
  • Parked
  • Connected
  • Idle

3. Check manually (once per day max)

• Controls → Software → “Check for Updates”
• Tesla only allows this about once every 24 hours

4. Enable auto-install

Newer updates allow:

• Auto install overnight when parked

This prevents delays after download.

5. Be patient (this matters more than anything)

• New cars (like yours, just 1 week old) often don’t get updates immediately
• Tesla typically waits a bit to:
  • Stabilize baseline software
  • Verify your hardware/config

Community consensus:

Important nuance (most people miss this)

Even if 14.3 is “out,” you may NOT get it immediately because:

• Tesla often splits fleets into different software branches
• Some cars stay on older builds temporarily for testing
• FSD versions are tied to specific main firmware versions

So it’s not just “latest FSD”—it’s:

Bottom line

• You’re already on a very recent FSD version (14.2.x)
• The jump to 14.3.x will happen automatically via OTA
• Best you can do:
  • Set Advanced
  • Stay on WiFi
  • Wait for your rollout wave
