In a post on X, Elon Musk confirmed that vehicles with Hardware 3 will be receiving FSD V12.5 in about 10 days.
When FSD V12.5 was rolled out initially, it only rolled out to Model Y vehicles with AI4 (Hardware 4). However, just a few days later, FSD V12.5 started rolling out to most AI4-based vehicles.
Hardware 3
Hardware 3 owners have been left feeling behind on this, especially since the divergence between Hardware 3 and AI4 wasn’t supposed to start happening until later this year. Elon has mentioned that even though AI4 is still emulating Hardware 3, the additional compute capacity available on the newer hardware makes it easier to develop.
This pretty much means that Tesla is developing for Hardware 3 but is using the unconstrained compute power of AI4 to test and do initial rollouts. After optimization, it then rolls out to Hardware 3 vehicles. This is similar to how most software is often made – on far better PCs, and then scaled down and optimized to better fit the average computer.
But Tesla clearly isn’t abandoning their Hardware 3 and Tegra-based infotainment (MCU 1) customers just yet. Update 2024.26.3 brings FSD V12 to MCU1 vehicles for the first time. These vehicles are based on an older infotainment chipset from NVIDIA. That’s a great leap in optimization and compatibility and demonstrates Tesla and Elon’s commitment to bringing Unsupervised FSD to any vehicle produced after 2016.
V12.5 is Significant
FSD V12.5.1 has also shown some amazing improvements, with the capability to navigate parking lots and unpaved/unmarked roads being demonstrated by AIDRIVR on X below. That’s one of the key components that Tesla will need for its Robotaxi, as well as for Actually Smart Summon, Park Seek, and Banish Autopark. And Elon has said that there is more to come.
We haven’t heard about these features making it to FSD V12.5 just yet, but we do know that sunglasses-capable hands-free, end-to-end highway stack, more natural lane changes, and Cybertruck FSD are supposed to be coming soon. This laundry list of improvements is found in the Update 2024.20.15 Release Notes, all listed as Upcoming Improvements.
We’re excited to see FSD V12.5 coming to Hardware 3 vehicles – especially as the vast majority of Tesla’s current fleet is still on Hardware 3, not AI4. While Elon has said Tesla doesn’t envision an upgrade path between Hardware 3 and AI4 due to the complexity, there’s always a chance Tesla will develop new AI4-based hardware that meets the power consumption capabilities and space constraints of vehicles running HW3.

Tesla previously told its employees on the Cybertruck production line that work would be halted for three business days and that they would not be required to show up to Giga Texas for any other work. Work was halted on the Cybertruck line from December 3rd until December 6th.
Many speculated that Tesla had hit a demand mark with the Cybertruck or run into other production-related difficulties. However, pausing production for such a short period is a fairly normal business operation, as Tesla continuously retools and upgrades its production lines.
Halts for business demand tend to look more similar to Ford’s F-150 Lightning production halt - where they halted production from November 18, 2024, until January 6, 2025. Ford also announced that this production halt was due to reduced demand for its electric truck in the face of stiffer competition.
Cybertunnel
In this case, part of the reason for the halt could potentially have been due to upgrades to the underground tunnel that is used to move Cybertrucks fresh from the production line to the holding lot at Giga Texas. Tesla has been working on improving the production flow rate for its vehicle - and rather than encountering issues with production, they’ve previously mentioned they’ve had issues with getting vehicles out of their outbound parking lots and off their assembly lines - and into customers’ hands fast enough.
The Cybertunnel moves trucks from inside Giga Texas to the holding lot just outside the factory. At that holding lot, they’re either loaded into trains or trucks to be transported across North America. The tunnel passes underneath Texas Highway 130, helping to ensure that Tesla isn’t clogging up traffic crossing the highway with brand-new trucks.
More Shut Downs?
It’s likely we’ll see even more shutdowns at Giga Texas in the coming months. Tesla has shown that it intends to continue increasing production rates at Giga Texas, which means it will need time to upgrade its assembly lines and processes. In addition, the Model Y is also produced at Giga Texas—and once the Model Y Juniper arrives, there will need to be shutdowns to accommodate re-tooling.
So, no need to stress - it's just regular operations. And we get to see a cool Cyber-themed tunnel too. In the meantime, check out Joe Tegtmeyer’s drone video of Giga Texas below.

Tesla’s FSD V13 introduced a host of new features, including the ability to Unpark itself, travel in reverse, and Park at its destination. While FSD can now navigate itself out of a parking spot or garage, there are limited options when arriving at your destination, but that’s about to change.
Garage Support
Ashok Elluswamy, Tesla’s VP of AI, confirmed on X that a future revision of FSD V13 will introduce a variety of parking options, including parking in garages, driveways, parking spots, or simply pulling over on the side of the road. Drivers will presumably be able to pick when choosing a location, or maybe the vehicle will offer suggestions based on the location.
This will be a big addition, as today, FSD doesn’t understand how to park in a garage or driveway. Some owners trick FSD into parking in their driveway by using tape or road paint to outline parking spots.
Soon, that may not be necessary, and instead, FSD will simply back itself into your garage. This feature will probably work best in larger garages—extremely tight garages may not work, given the reduced precision of vision at extremely close distances.
We hope that if Tesla introduces this feature, they’ll sell printable guides you can stick on the garage walls or floor to help ensure your vehicle is in the perfect spot every time. Many commenters mentioned that they park in urban/suburban garages with only inches to spare around their vehicles, so this will be an interesting challenge for Tesla to address.
Parking Garages
Parking garages offer their own unique problem set. For the most part, FSD can already navigate its way out of a parking garage, assuming that there aren’t any special gates or sequenced/signaled signage.
It is also able to find a parking spot in multi-level garages and navigate its way out. More support for multi-level parking garages is coming, as FSD seems to stick to the garage walls until it can find the exit itself. It seems that Tesla’s data gathering and vehicle-to-fleet communication could aid Tesla in figuring out parking garages in terms of knowing the entrances and exits.

In the Upcoming Improvements section of FSD V13, Tesla mentions that more destination options will be supported, including pulling over (at the side of the road) and parking in a spot, driveway, or garage.
These other destination options are going to be important soon - because one of the biggest FSD features we’re all still waiting for is Banish AutoPark. Once your vehicle can pull over at the entrance of a location and then go park itself, we’re going to be super close to Unsupervised FSD becoming a reality.
