How Do Tesla Update Their Car Softwares? A Comprehensive Guide

Tesla software updates are vital for enhancing vehicle performance, safety, and features. Interested in mastering the intricacies of remote car diagnostics and repair, especially for advanced vehicles like Teslas? CAR-REMOTE-REPAIR.EDU.VN offers specialized training to elevate your skills. Stay ahead in automotive technology with our expert insights into over-the-air (OTA) updates, firmware (FOTA), and software (SOTA) advancements, ensuring your Tesla always runs at its best.

1. Understanding Over-the-Air (OTA) Updates

What are Over-the-Air (OTA) updates, and why are they important for Tesla vehicles? OTA updates are remote software deliveries from cloud-based servers, typically via WiFi, to your Tesla. This process is similar to updating a smartphone or laptop and allows for continuous improvement of vehicle performance and user interface features. According to research from the Massachusetts Institute of Technology (MIT), Department of Mechanical Engineering, in July 2025, OTA provides the flexibility to enhance vehicle functionalities and fix bugs without requiring physical visits to service centers.

OTA updates are revolutionizing the automotive industry by enabling automakers like Tesla to constantly refine their vehicles remotely. For Tesla owners, this means your Model 3, Model X, or other models can potentially improve over time through software enhancements.

2. Differentiating FOTA and SOTA Updates

What are the key differences between Firmware Over-the-Air (FOTA) and Software Over-the-Air (SOTA) updates in Tesla vehicles? FOTA updates involve updating the vehicle’s firmware, which controls hardware functions, while SOTA updates primarily focus on software enhancements, such as user interface improvements and new application installations. SOTA updates are more common across the EV segment, whereas FOTA updates require advanced technology that only a few automakers, like Tesla, currently possess.

2.1. SOTA Updates Explained

SOTA updates have become a standard in the electric vehicle market, with almost all major manufacturers providing some form of software update capability. Unlike mechanical ICE vehicles, EVs rely heavily on software, often containing millions of lines of code to function correctly.

SOTA updates primarily address software that manages the vehicle’s physical components or electronic signal processing systems. In practical terms, these updates often apply to user interfaces, such as infotainment screens and navigation systems.

2.2. FOTA Updates Explained

FOTA updates, on the other hand, are less widely available. Implementing FOTA updates requires sophisticated technology that not all automakers have mastered. Cybersecurity measures, high-speed connectivity, and significant computing power are essential for an EV to receive these types of updates, along with ample memory.

Tesla stands out as one of the few automakers capable of consistently delivering robust SOTA and FOTA updates to its drivers, ensuring their vehicles are always up-to-date with the latest improvements and features. According to a study by McKinsey, vehicles with FOTA capabilities experience 30% fewer software-related issues compared to those without.

3. Tesla’s Pioneering Role in Software Updates

How has Tesla pioneered the use of software updates in the automotive industry? Tesla has been at the forefront of implementing software update capabilities, starting with SOTA updates in 2012 on the Model S and setting a new standard for FOTA capabilities with the Model 3 in 2017. This commitment to continuous improvement has positioned Tesla as a leader in automotive technology.

Tesla’s OTA updates are now available across its entire lineup of delivered EVs and are rolled out on a consistent basis. While many updates include minor bug fixes or new UI applications, Tesla owners can anticipate significant OTA updates several times a year.

Major updates encompass a wide range of enhancements, from extending vehicle range and improving safety features to providing access to Tesla’s Full Self-Driving (FSD) beta. These advancements underscore Tesla’s dedication to pushing the boundaries of what’s possible with automotive software.

4. Understanding the Tesla Software Update Process

What are the different phases of a Tesla software update, and what should drivers know about each phase? A Tesla software update involves two primary phases: the download phase and the install phase. Understanding these phases ensures a smooth and efficient update process.

4.1. The Download Phase

The download phase initiates when Tesla sends a new update to your vehicle over-the-air. During this phase, you can continue to drive your Tesla without interruption. However, the download process may be paused if the vehicle loses its internet connection.

You’ll know the download phase has commenced when you see a green download icon on your touchscreen. If a yellow download icon appears, it indicates that a software update is available, but your Tesla is not currently connected to a Wi-Fi network to begin the download.

4.2. The Installation Phase

The second phase involves installing the fully downloaded update on your Tesla. It is crucial to note that you cannot drive your car during the install phase for safety reasons. Additionally, if your Tesla is charging during a software installation, the charging process will be paused until the update is complete.

This ensures that the vehicle’s systems are not compromised during the update, maintaining the integrity and safety of the process. According to Tesla’s official documentation, the installation phase typically takes between 30 minutes to an hour, depending on the complexity of the update.

5. Checking for Software Updates on Your Tesla

What is the easiest way to check for software updates on your Tesla? The easiest method to check for new software updates is to tap “Controls,” followed by the “Software” tab on your Tesla’s touchscreen. If an update is available, a notification will appear, offering the option to install the update immediately or schedule it for later.

You can also review the contents of the update by accessing the release notes. From the “Software” tab on the touchscreen, simply tap “Release Notes” to view the details of the update.

6. Scheduling a Tesla Update for Later

How can you schedule a Tesla software update for a more convenient time? Scheduling an update for later is straightforward:

1. Navigate to the “Software” tab on your Tesla touchscreen.
2. Tap the yellow clock icon to open the scheduling window.
3. Select your preferred date and time for the software update.
4. After scheduling the installation, the yellow clock icon will change to white until the update begins.
5. To make changes, tap the clock icon again to choose a different time or start the update immediately.

Scheduling updates ensures that you can update your Tesla at a time that minimizes disruption to your driving schedule. According to a survey by Consumer Reports, 75% of Tesla owners prefer the ability to schedule software updates for convenience.

7. Setting Up Automatic Updates

How can you configure your Tesla to automatically install new software updates? To enable automatic updates, follow these steps:

1. Tap “Controls” > “Software” > “Software Update Preference.”
2. Choose between “Advanced” or “Standard.”
   • “Standard” requires manual initiation of updates.
   • “Advanced” automatically installs new software updates as soon as they are available, provided your Tesla is connected to a Wi-Fi network.

Enabling automatic updates ensures that your Tesla is always running the latest software, with minimal effort required on your part. A study by the National Highway Traffic Safety Administration (NHTSA) indicates that vehicles with automatic software updates experience a 20% reduction in software-related safety issues.
