Last night Tesla released FSD V13.2.1 with software update 2024.39.15. While the update is still going out in very small waves, it’s the first time FSD V13 has gone out to users beyond the initial early-access testers.

The update is going out to all HW4-based models, including the new Model S/X and the Model 3/Y, and includes the Cybertruck for the first time.

FSD V13

FSD V13 adds various new features, including the ability to start FSD from Park, Reverse, and Park at Destination. However, not all features are available on the Cybertruck yet. You can check out our detailed examination of the FSD V13.2 features here.

Start FSD from Park is also called Unpark - and it means that you can select your destination, and then tap and hold the new Start FSD button. FSD will engage, shift out of park, and into drive or reverse to get to your destination.

Next up, FSD is now capable of driving in reverse. It can now shift into reverse as required and will shift between the three gears as needed (Reverse, Drive, and Park). This means that FSD can now perform 3-point turns when necessary.

Finally, when FSD reaches its destination, it will navigate to an open parking spot if one is nearby and available. For now, FSD will only look for open parking spots, but soon you’ll be able to pick what the vehicle should do when arriving at its destination.

Take a look at the video below of one of the first drives of FSD V13.2.1.

What’s New

This update is essentially a bug fix for the Model S, 3, X, and Y. However, the Cybertruck is receiving a modified release that’s missing several features compared to the other vehicles receiving 13.2.1. Here’s what’s missing from the Cybertruck version:

First off, Cybertruck does not get integrated Park, Unpark, and Reverse for the time being. In addition, there still isn’t support Actually Smart Summon in this release. With this update, Tesla is calling out the “Start FSD (Supervised) from Park” feature as a separate item in the release notes due to some changes (more on this below), but this is also not available on the Cybertruck.

This is likely because further refinements are needed for Cybertruck to be able to park itself or move accurately in tight spaces. The Cyebrtruck is significantly larger than other Tesla vehicles, and Tesla is likely waiting for more validation tests before releasing Summon or the Park-related features outside of Auto Park. T

Two other items missing from the Cybertruck version are Improved Camera Cleaning and the Redesigned Controller for smoother and more accurate tracking. Both are listed in the upcoming improvements section for the Cybertruck. Everything else in the release notes is identical to the other models.

Interestingly, this update still does not include the holiday update, so while users on FSD V13.2.1 get to enjoy the latest FSD build, they still do not have access to the features in the Holiday Update.

Start FSD From Park

WifeDirtyTesla

While FSD V13.2 included Start FSD from Park, it’s getting some changes in this update. Tesla is now specifying that the driver must be in the driver’s seat and buckled and that the camera camera must be unobstructed.

The process for starting FSD from Park has also been slightly adjusted. By default, you’ll need to tap and hold the Start FSD button after meeting the requirement above, but after pressing the on-screen button, you’ll also need to press the brake pedal before FSD is activated.

This seems like an additional safeguard to prevent accidental use of the feature, but it is optional. You can turn off the additional safety measure by going to Controls > Autopilot and turning on Start FSD (Supervised) from Park.

This feature is expected to arrive for the Cybertruck in a future release.

Upcoming Improvements

The Upcoming Improvements section doesn’t mention any features that weren’t previously mentioned in the FSD 13.2 update, which includes the following features:

  • 3x model size scaling

  • 3x model context length scaling

  • Audio inputs for better handling of emergency vehicles

  • Improved reward predictions for navigation

  • Improvements to false braking and slower driving in parking lots

  • Support for destination options including pulling over, parking in a spot, driveway, or garage

  • Efficient representation of maps and navigation inputs

  • Improved handling of camera occlusions

That’s an extensive list of upcoming improvements for FSD V13, so we’ll be seeing lots of changes and improvements as FSD approaches its Unsupervised phase in the near future.

Hardware 3?

Sadly, Tesla did not mention HW3 in their previous roadmap update and hasn’t referred to it since the original roadmap update. HW3 vehicles recently received the Holiday Update alongside FSD V12.5.4.2, which is the latest FSD build for HW3.

Besides saying that a future hardware upgrade will be available if Tesla can not achieve Unsupervised FSD on HW3, Tesla has been mum on the situation. However, there’s no word on whether FSD V13 will be made available on HW3 vehicles before such an upgrade is available.

There’s a good chance that Tesla will create a smaller model version of FSD V13 that’s capable of running on HW3 and is capable of some of the same abilities we’re seeing on HW4-based vehicles running FSD V13. However, it’s clear that Tesla’s focus is achieving Unsupervised FSD and meeting their goal of running it out next year.

HW3 vehicles are still waiting on the merger of the city and highway stack, so we’re hopeful we’ll see that, at least that, if not V13 in the coming months.

Update: This FSD update (V13.2.1) is now going out to all HW4 vehicles in the U.S. and Canada. Read our article here on when you can expect to receive it.

Tesla Semi Keynote: New Features, 46 Charging Sites, Upgraded Battery & More [VIDEO]

By Karan Singh

Tesla’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.

Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.

Semi Factory & Production Ramp

Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.

Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.

Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.

Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.

New Tesla Semi Features

Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.

New Electric Power Take-Off (e-PTO)

The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.

Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.

On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.

46 Semi Charger Sites Coming

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.

This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.

The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.

Tesla’s B-Pillar Sentry Mode Recording Requires HW4, Not Just Ryzen — Breakdown of Spring Update Requirements

By Karan Singh
Not a Tesla App

Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.

B-pillar Camera Recording and Dashcam Viewer

With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.

This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.

These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.

However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.

Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough

We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.

For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.

While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.

Cybertruck Also Missing Improved Sentry Mode

Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.

Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.

Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.

Adaptive Headlights

Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.

All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.

If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.

Legacy Model S & Model X

As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.

Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.

These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.

While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
