Every Tesla update is filled with new features, but often there are smaller improvements that aren’t missed in the release notes and go unnoticed. Now that most users, except those on some FSD releases, have received update 2024.38, we’re taking a look at some of the features that Tesla didn’t mention in their release notes.

Service History

Mahtava

Tesla's new Service History, available through Tesla's Service Mode, lets owners and technicians add service records to the vehicle.

Each service record is permanent and can not be amended once it has been entered. You can enter a variety of service records, from simple owner-oriented tasks, such as windshield wiper replacements and adding washer fluid to motor or battery pack swaps. If you’re interested in learning more, read our deep dive into Service History.

With Tesla’s Holiday Update, Tesla also made this information viewable (read-only) for vehicle owners without the need to go into Service Mode. Owners can simply go to Controls > Service > Maintenance Summary to view their vehicle records.

Tesla App Commands

When you're in close proximity to your vehicle, commands issued from the Tesla app will now be executed quicker and more reliably by being sent over Bluetooth instead of relying on your phone’s and vehicle's internet connection.

This requires a recent version of the app, which can be Tesla app update 4.38 or higher.

This feature is available for both iPhone and Android and supports all vehicles except the legacy Model S and Model X.

Curve Assist

Not a Tesla App

In certain regions, Tesla has added a new Curvature Assist feature that allows the vehicle to perform sharper turns while on Autopilot. When the feature is active, the vehicle will display "Curvature Assist Active" in the visualization area.

Autopilot Hardware Version

Not a Tesla App

Up until now, it wasn't always easy to tell whether your vehicle had Autopilot hardware 3 or hardware 4. With update 2024.38, Tesla shows your vehicle's Autopilot hardware in the Software tab.

Simply go to Controls > Software, and underneath your car's VIN, you'll see the FSD hardware version of your car. The version can be cut off in some languages due to the longer text, but you can also tap the Additional Vehicle Information to view the Autopilot hardware version.

WiFi Diagnostics Tool

Tesla now includes a WiFi Diagnostics tool to help you improve your WiFi connection. It displays your connection’s status and speed and provides some tips.

To view WiFi Diagnostics, go to Control > Wi-Fi and tap on the blue Diagnostics link at the top.

The diagnostics tool allows you to see various details about the access point you're connecting to, your vehicle's MAC address, and your connection.

Improved Voice Recognition

Many users are also reporting voice recognition improvements in this update, especially in dialects other than American English. Tesla's voice command system now appears to better understand different accents and perform commands more reliably. While this isn’t the smart voice assistant we all wanted, many users are happy to be able to issue commands more reliably.
