Tesla Software Update 2025.2 - Hands-Free Trunk Support for Android, Rear Cross-Traffic Chime

Not a Tesla App

Tesla’s first major update of 2025, software update 2025.2, is now rolling out to select vehicles in North America and Europe. While the update isn’t widespread yet, it is rolling out to most vehicles, including HW3 and HW4 cars. The Cybertruck and legacy Model S/X vehicles are currently the only vehicles that haven’t received this update.

Let’s take a look at everything we know that’s included in this update.

Third-Party Charger Preconditioning

First up, vehicles will now support preconditioning for third-party chargers. While this was previously available in Europe for approved third-party chargers that met Tesla’s strict standards, it’s now available in North America for the first time.

What’s New: When you navigate to a charging location, whether it’s listed in the vehicle’s charging locations or not, the vehicle will now precondition the battery for faster charging. It looks like the vehicle will automatically determine if the destination is an EV charging location and enable preconditioning. If the destination is a charging location, you’ll see a little banner show up, letting you know the vehicle’s battery is now being preconditioned. There isn’t a button to manually precondition the battery yet.

What’s Not Added: In Europe, the vehicle's charging filter shows approved third-party chargers. Unfortunately, it does not look like this is being added in North America, where Tesla only displays Superchargers and destination chargers. However, the above feature still applies in North America, where the vehicle will precondition the battery for fast chargers such as Electrify America.

The video below shows how the feature will work:

Rear Cross-Traffic Chime

Following up on the addition of rear cross-traffic alerts showing up as red indicators as part of the 2024 Tesla Holiday Update, Tesla is now adding an alert chime to go with it. Now, there is a visual indicator on the screen, as well as an audible indicator that a vehicle or object has been detected crossing behind you.

This is a great addition and almost looked like a glaring omission in the initial release of the feature. Tesla likely wanted to make sure the feature was working as expected in the wider fleet before introducing a more drastic alert.

The chime is enabled by default, but if you want to disable it, you can go to Controls > Safety > Rear Cross-Traffic Chime to disable it. Joe Mode will reduce the chime’s volume if you prefer that instead.

Interestingly, the rear cross-traffic alerts feature was a feature that Musk said “Yes” to back in 2020.

Hands-Free Trunk/Frunk for Android

Just recently, we reported that Tesla was adding ultra-wideband support for Android - which would include two new major new features.

Improved Phone Key Reliability: Ultra-wideband (UWB) is an alternative to Bluetooth, which offers highly accurate positioning and tracking of devices. It uses about the same amount of energy as Bluetooth Low Energy but with increased location accuracy. By having your phone communicate with the vehicle over UWB, the vehicle knows exactly where your phone is in relation to the car, drastically increasing the reliability of your vehicle’s phone key.

Hands-Free Trunk and Frunk Opening: More precise location tracking enables new features such as Hands-Free Trunk and Hands-Free Frunk support. This feature has been available on iOS devices for approximately a year and will now be available on Android devices.

Supported Models: Unfortunately, not all models are supported, and your vehicle needs to have ultra-wideband sensors. Supported models include the 2021+ Model S and Model X, the 2024+ Model 3, the Cybertruck, and the upcoming 2025+ Model Y. Only the Model S, Model X, and Cybertruck support the hands-free frunk.

Supported Phones: Most recent Android phones support ultra-wideband, especially flagship devices, however, it’s not available on all phones. If you have a Google Pixel 6 or higher, Samsung Fold 2 or higher, Samsung S21+, or other recent Android phone, then your phone already supports ultra wideband.

Users with Android devices with UWB will initially be prompted to “Upgrade” their phone key when opening the Tesla app. This will switch your phone key from using Bluetooth to ultra-wideband. Once upgraded, you can go to Controls > Locks > Hands-Free Frunk / Trunk in your vehicle settings to enable the new hands-free feature. If you aren’t prompted for the upgrade, you’ll find it under Security & Drivers > Phone Key > Upgrade in the Tesla app.

Weather Information

With every Tesla update, there are smaller features, and this one is no different. In this update, the weather information is now displayed for both the final destination and any additional stops (waypoints) you have set along the way. Previously, the weather would only be displayed for your current location and your destination.

Battle of Polytopia

Next up, Battle of Polytopia is receiving another update. This time “The Forgotten” skin is being added for the recently-added Aquarion faction, adding some old-world Atlantis vibes to the fishy folk. Additional language support and balance changes are also included in this Battle of Polytopia update.

Cybertruck Charging Improvements

Last month we reported that The Cybertruck is expected to receive charging and regenerative braking improvements soon. Tesla was aiming at releasing these updates in the 2025.2 update, so there’s a chance that these cold weather improvements are also included in the 2025.2 update, but we won’t know for sure until the Cybertruck starts receiving this update in the coming days or weeks.

Other Features?

Since this update hasn’t rolled out to all models or regions yet, it’s possible we may see some additional features added in this update, although at this point, it may only be features for the Cybertruck or the legacy Model S and Model X.

Finally, as usual, Tesla includes minor fixes, performance enhancements, security fixes, and improvements. If you notice any undocumented changes, please let us know.

Tesla’s Charging Snake and Upcoming V4 Wireless Charging Compatibility

Not a Tesla App

The Ride the Lightning podcast recently featured Tesla’s VP of Engineering, Lars Moravy, covering a wide range of topics—including the upcoming Model S and Model X refresh. However, some of the most intriguing details came from his comments on Tesla’s charging technology.

Moravy revisited Tesla’s once-hyped robotic charger snake, which was showcased years ago before quietly fading from the spotlight. He also dropped an interesting remark about wireless charging but didn’t go into detail.

Death of the Charger Snake

When discussing the Charger Snake, Lars had some strong opinions. It was an internal Tesla project that never gained much traction because engineers ultimately felt it wasn’t necessary.

At Superchargers, most people leave their vehicles to grab food, a drink or simply stretch—making manual plugging the vehicle in a non-issue. There was little justification for a complex, maintenance-heavy robotic charger, especially considering the challenges it would face in winter conditions. Just imagine the nightmare of keeping it operational in snow and ice.

But what about autonomous charging? As Tesla moves toward full autonomy, vehicles will need a way to charge without human intervention. And it isn’t like a Robotaxi passenger is going to like the idea of getting out of their vehicle to plug in either - which would ruin the seamless experience.

Wireless Charging and V4 Superchargers

Not a Tesla App

That’s exactly where Tesla’s wireless charging comes in. We got an early glimpse of its design during the We, Robot autonomy event, where the Cybercab was shown charging wirelessly—without a traditional charging port.

Compared to complex robotic systems for handling charging cables, wireless charging is a far more practical solution. A simple charging mat eliminates the need for moving parts while allowing vehicles to charge without human intervention.

In the future, Supercharger stations will likely support both wired and wireless charging, enabling Cybercab users or owners to charge their vehicles while sleeping, watching video content, or simply relaxing—without ever needing to step outside. Wireless charging may also be cheaper to install than a complete Supercharger stall, which Tesla is now able to install for below $40k per stall.

And here’s the most exciting part. When asked whether wireless charging would require new infrastructure, Lars hinted:

“Could be. But we’re making some smart plays about that with the new V4 Superchargers…”

This suggests that as Tesla expands its V4 Supercharger network, it will include wireless charging capabilities in the upcoming V4 cabinets. While every stall won’t need wireless capabilities, having the ability to add a few wireless chargers per major location will be enough to kickstart Tesla’s Robotaxi network.

Cybertruck Wins Best Tech Award by MotorTrend; Tech Coming to Other Teslas

MotorTrend

The Cybertruck has been named MotorTrend’s 2025 Best Tech Winner for chassis technology—but surprisingly, not for its stainless steel exterior. Instead, the award recognizes its Steer-by-Wire system.

Steer-by-Wire is a technology that many automakers have explored for years, but Tesla was the first to bring it to mass production. Now, tens of thousands of Cybertrucks across North America are driving with this cutting-edge innovation.

As one reviewer put it, “Steer-by-Wire feels as natural as riding a bicycle.”

What is Steer-by-Wire?

Most modern cars use a rack-and-pinion steering system, which creates a mechanical link between the steering wheel and the front wheels. To make steering easier, most vehicles incorporate hydraulic or electric power assist, reducing the effort needed to turn the wheels.

The steering ratio determines how many turns of the steering wheel are needed to move the front wheels from lock to lock. In most cars, this requires 3 to 3.5 full turns, translating to a ratio between 12:1 and 20:1.

Some high-performance sports cars also feature adaptive variable-ratio steering, which adjusts based on speed. At higher speeds, the ratio becomes less aggressive, allowing for added precision and control.

How it Works

The Cybertruck uses a fully electronic Steer-by-Wire system, eliminating any mechanical connection between the steering yoke and the wheels. Instead, the yoke sends inputs to a computer, which then controls independent electric motors dedicated to steering the front and rear wheels.

This redundancy ensures that even if one steering motor fails, the vehicle remains steerable through the other. Tesla also built in a backup power system—one motor runs on 48V low-voltage power, while the truck’s high-voltage battery powers the other.

The steering inputs are triple-redundant, with two primary sensors monitoring wheel angles and a third acting as a tie-breaker. If the two primary sensors detect conflicting data, the tie-breaker determines the correct reading, and the system alerts the driver to pull over safely if needed. Tesla’s engineering played a key role in the Cybertruck earning a 5-star safety rating.

Beyond safety, the system also features a variable steering ratio. At low speeds, such as in parking lots, the ratio is around 5:1, making tight maneuvers easier. At higher speeds, it adjusts to around 12:1 for greater stability. Unlike traditional steering wheels, the Cybertruck’s yoke maxes out at 340 degrees, removing the need for hand-over-hand turning.

The system is surprisingly intuitive. According to MotorTrend, it only took them three turns to get comfortable with how the Cybertruck steers, describing it as feeling almost natural.

Because of how the steering is designed, there’s rarely a need to remove your hand from the yoke—unless you’re using FSD. Whether navigating a tight parking lot, off-roading, or cruising on the highway, maneuvering a full-size truck has never been this effortless.

Rear-Wheel Steering

With the Cybertruck’s ability to turn its rear wheels, driving it feels almost effortless. Even if you’re not a fan of its design, we highly recommend visiting a Tesla showroom and taking one for a spin—you won’t regret it. The Cybertruck delivers one of the most enjoyable driving experiences, something you’d never expect from its bulky stainless steel exterior.

At low speeds, the rear wheels turn in the opposite direction of the front wheels, greatly reducing the turning radius for tighter maneuvers. At higher speeds, they turn in the same direction as the front wheels, allowing for smooth, stable lane changes without requiring dramatic steering adjustments. This makes highway driving feel remarkably fluid and controlled.

Steer-by-Wire Coming to More Models

Tesla has already confirmed that future vehicles will adopt features pioneered by the Cybertruck, with Steer-by-Wire being one of them. Since this technology requires a 48V low-voltage architecture, Tesla’s VP of Vehicle Engineering, Lars Moravy, mentioned on the Ride the Lightning podcast that it will be introduced in future models. Moravy also mentioned that the Model S and Model X will be updated later this year, potentially being the first models to take advantage of this.

The main challenge lies in transitioning to a 48V supply chain. Eventually, all Tesla vehicles will operate on 48V, likely incorporating Steer-by-Wire as well. This change should result in simplified parts, easier repairs, and improved handling.

As MotorTrend put it, when Cybertruck engineers replaced the traditional intermediate shaft with a ribbon cable, they didn’t just redefine how to steer a truck—they set the stage for the future of the entire industry.
