Tesla Releases FSD V13.2.1 - What's New

DirtyTesla

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 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.

V13 is MINDBLOWING.

Here’s the first drive video with FSD v13.2.1. 31 mins from parking lot to parking spot with ZERO disengagements or interventions. I can’t believe how smooth it is- it’s incredible.

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 Improves Steer-by-Wire and Adds In-App Suspension Control in Cybertruck Update 2025.8.4

Not a Tesla App

Tesla proves once again that it listens to its customers, and this is a perfect example. Since the Cybertruck’s launch with an adjustable air suspension, owners have been requesting suspension-related features.

One major request is the ability to remotely adjust the vehicle’s height. This could previously only be done from inside the cabin via the touchscreen, but Tesla has now added it to the latest version of the Tesla app. However, using the feature also requires vehicle software 2025.8 or higher.

This software update also brings improvements to the Cybertruck’s steer-by-wire system, which is set to come to future Tesla models. Unlike traditional rack-and-pinion steering, steer-by-wire is not directly connected to the wheels like other vehicles, and “road feel” does not carry through to the steering wheel. Instead, Tesla implements software-driven wheel feedback, which is being improved in this update.

Remote Height Adjust

Now, as of Tesla software update 2025.8 and Tesla App V4.42.5, Cybertruck owners can remotely adjust the height of their Cybertruck through the Tesla app. This setting is in the Controls section of the app.

Here, you can adjust to the four pre-set road heights, including High, Medium, Low, and Entry. For now, you cannot adjust to the two Off-Road Mode heights, which are Very High and Extract.

Now, if you don’t own a Cybertruck, you’re probably wondering why so many are asking for this feature. Well, if you want to go off-roading or even want to load something into the bed of your truck, it’s convenient to be able to remotely adjust the height of the car without having to go in it first.

You can also use it to show off the Cybertruck’s massive vertical range of motion - which can go nearly eight inches from Entry to Extract - all without having to hop into the Cybertruck.

Model S and Model X?

This feature could also potentially make its way to the Model S and Model X sometime in the future since both of these vehicles also have an adjustable air suspension. Today, the heights of these vehicles can only be adjusted inside the vehicle.

We’re sure some Model S and Model X owners would love to be able to adjust the suspension remotely, even if they may not have the same use cases — it’s still a nice to have feature.

Steer-by-Wire Improvements

Tesla has improved the Steer-by-Wire feedback and response on the Cybertruck’s yoke. This new update should provide more realistic wheel feedback. The feedback will now adapt to different road surfaces for a better driving experience.

That means the response and feedback of the wheel will now be more precise - and also be varied by what kind of terrain you’re driving on.

More Features

One more thing we’d love to see from Tesla regarding the Cybertruck is the ability to drop just one side of the suspension. This is possible in Service Mode, where you can deflate either the front or rear air tanks, thereby inducing a slant to the vehicle.

This makes loading items even easier, as the bottom of the tailgate is now even closer to the ground. Tesla showed off the feature during the Cybertruck’s initial reveal. While the Cybertruck never arrived with its built-in ramp, we’d still love the ability to dip the truck for easier loading.

Another feature that was supposed to arrive for the Cybertruck was related to Steer-by-Wire. Today, the Cybertruck can steer up to 7 degrees, but the actual hard limit for the rear wheels is somewhere between 10 and 14 degrees. We’d love to see Tesla expand the rear wheel steering limits which will help reduce the Cybertruck’s already tight turning circle.

Tesla's Model 3 Performance Improves FSD Comfort by Changing Ride & Handling Setting

Not a Tesla App

Tesla continues to refine ride comfort, especially with FSD, where it aims to make every drive as smooth as possible. With the new Model 3 Performance, Tesla is introducing a new feature that allows for an even smoother ride while using FSD.

With the 2025.8 update, the vehicle will now automatically switch its suspension setting to Standard when FSD is enabled. This adjustment reduces road feel but improves ride comfort—a worthwhile trade-off while FSD is active.

The release notes state:

“Your vehicle will now automatically transition to Standard Ride & Handling when Autopilot is engaged for a more comfortable drive. This setting is enabled by default. To disable, tap Controls > Dynamics > Use Standard Ride & Handling in Autopilot.”

Dynamic Suspension

On the New Model 3 Performance, Tesla includes a dynamic, adaptive suspension system. While it isn’t an air-ride adjustable suspension like on the Model S, Model X, and the Cybertruck, it is an actively dampened suspension that improves the ride quality.

There are two settings for the dynamic suspension, which can be controlled from Controls > Dynamics > Ride & Handling.

Standard - Adjusts to a wide range of roads and driving styles, providing a fluid yet well controlled ride.

Sport - Provides a firmer, more controlled ride that increases driver engagement and connection to the road.

Many people prefer to drive on Sport as the road feel on the Model 3 Performance is fantastic, and even more so on a track.

FSD Will Use Standard Suspension

Tesla’s FSD aims to provide a comfortable trip from point A to point B, which means that connecting the driver with the road isn’t necessarily a goal here. Instead, as of software update 2025.8, FSD will now default to the Standard suspension setting instead of Sport. If you have Sport enabled, then FSD will switch to Standard when FSD is enabled and switch back to Sport when FSD is disengaged.

Many users will prefer using Standard when on FSD, but switching back and forth between suspension options isn’t feasible, so this is a great addition. However, if you prefer for the vehicle to remain in the Sport setting while FSD is enabled, you can turn off the “Use Standard Ride & Handling in Autopilot” in Controls > Dynamics.

Model S / Model X Setting

This feature for the new Model 3 Performance (2024+) is similar to the automatic ride height controls on the Model S and Model X. By default, these controls will automatically set the Suspension Damping option to Comfort when engaging Autopilot or FSD. Just like with this new setting for the Model 3, you can turn that off in Controls > Dynamics > Adaptive Suspension Damping in Autopilot.

We expect that when the new Model Y Performance is released in the coming months, it’ll also feature a similar setting.
