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.
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.
Tesla has begun reaching out to some its early Foundation-series Cybertruck customers to offer them the opportunity for a free upgrade of one of their drive units.
They seem to be doing this for both the Dual-Motor AWD variant, as well as the Tri-Motor Cyberbeast variant. So far, we’ve confirmed two such occurrences.
Drive Swaps
In the messages from Tesla Service, Tesla confirms that they are conducting a study on drive units in early Cybertruck vehicles and that some owners are being selected to participate. At the next service visit, Tesla will replace one of the current drive units, with a brand-new unit – one that is intended to improve efficiency and reliability.
Tesla Service also confirms that this isn’t a cause for concern and that the vehicle is still safe to drive in the meantime. This doesn’t seem to have been prompted by a recall, but is instead Tesla looking to perhaps take apart well-used drive units from its early models, and examine them for wear and tear so that they can be improved in future iterations.
Tesla’s FSD V12.4.2 has landed in the wild – at least among early-access customers this week. There have been a few videos and some folks have begun to provide feedback on X, on the update and how it's going.
For now, it hasn’t gone wide to customers and only early-access testers and employees have it on their vehicles. FSD 12.4.2 is update 2024.15.10 and it’s expected to be available to everyone on update 2024.14 who owns or subscribes to FSD… eventually.
Consistent, Confident
Early-access testers have found FSD V12.4.2 to be considerably more confident, and more consistent when it makes decisions. V12.4.2 seems more confident when making unprotected left turns and encountering construction or complex interchanges.
They’ve also had more consistency and confidence with the Auto Speed feature, which adjusts the vehicle’s speed automatically based on traffic conditions, and also noted that it has improvements with lane selection, which was a larger issue in V12.4.1.
Users have also noted that the Vision-Based Driver Monitoring System is more confident and can see better at night. On V12.4.1, the Vision-Based DMS was unavailable at nighttime, and nags would still occur – but on V12.4.2, this restriction appears to be removed.
Regressions
There are still some regressions, with @DirtyTesLa on X noting that V12.4.2 seems to fail a left turn on an unmarked dirt road that it has previously made.
@WholeMarsBlog also noted that he had one critical safety intervention and that FSD missed a turn onto the highway, noting it was a regression from his experience on V12.4.1. Overall, he has had multiple intervention-free drives.
