Following the recent release of V12.4.2 to employees and early access testers, Tesla has now released V12.4.3 to employees, according to X user Farzad. The update is version 2024.15.15.
We recently took a deeper look at the new features available on V12.4.2 here.
Given how rapid-fire Tesla has begun releasing updates to internal testers, employees, and early-access customers, it seems there could be a couple more iterations of V12.4 before it hits customers, as Tesla tunes FSD.
Update: As expected, the release notes remain the same as FSD v12.4.2 and this update just includes bug fixes.
Update 2: In the past hour, early-access customers (“OG testers”) have started receiving this update. This is the first time FSD 12.4.3 has gone out to the public. These owners were previously on FSD 12.4.2, which also didn’t go into a wide release. Given how fast this update went to employees and then to OG testers, Tesla must be testing a specific issue that quickly passed testing. We could see this version expand to additional customers later this weekend or early next week.
Update 3: Tesla has now expanded the rollout to more customers. It has now gone beyond the “OG” testers and to many regular customers. You can follow the progress of the rollout on our statistics page for FSD 12.4.3. This appears to be the version that will go wide to everyone that’s still on a 2024.14 update.

Why so many Versions and Delays?
While nobody is happy about delays, one needs to keep in mind that Tesla has to keep safety as a priority for FSD releases. If a release goes out wide to hundreds of thousands of vehicles that are unsafe, there could be considerable impacts on people’s lives.
Beyond that, each subversion is Tesla adjusting their AI model, fine-tuning it to be able to better drive in both normal and edge cases. As such, watching these subversion releases go by is a good thing – at the end of the day, we’ll end up with a better, safer product.
Every version also has to be tested internally first among their dedicated ADAS testers, then among employees, and finally with Tesla’s early-access customers. Once all these people give a green light, and most errors and major bugs are addressed, does a release get the green light to go wide.
So, stay tuned for when this release goes out wider than this leak and possibly comes to your vehicle with nag-free FSD.
