Can You Add Full Self-Driving to a Used Tesla? A Comprehensive Guide

The short answer is a resounding yes, you absolutely can add Full Self-Driving (FSD) capability to a used Tesla. However, the specifics of how and what you’ll be paying for it depend on a few key factors, including the age of the car and what Autopilot features it already possesses. Let’s dive deep into the electrifying world of FSD upgrades and what you need to know before taking the plunge.

Understanding Tesla Autopilot and Full Self-Driving

Before we get into the specifics of adding FSD to a used Tesla, let’s clarify what we’re actually talking about. Tesla’s Autopilot is a suite of advanced driver-assistance systems (ADAS) designed to automate some driving tasks, such as steering, accelerating, and braking within its lane. It comes in several iterations:

Basic Autopilot: Standard on all new Teslas, it includes Traffic-Aware Cruise Control and Autosteer.
Enhanced Autopilot (EAP): This previously available option included Navigate on Autopilot, Auto Lane Change, Autopark, and Summon. Tesla has intermittently offered and removed EAP as an option over the years.
Full Self-Driving (FSD): The most advanced option, FSD aims to provide a truly autonomous driving experience (though still requiring driver supervision). It includes all features of Autopilot and Enhanced Autopilot, plus Traffic Light and Stop Sign Control, and Auto Steer on City Streets.

The Cost of Adding FSD to a Used Tesla

The price of FSD for a used Tesla primarily depends on two things:

Whether the car already has any Autopilot features: If your used Tesla only has Basic Autopilot, you’ll be paying the full FSD price, which currently hovers around $12,000 USD (as of late 2024).
The age and computer hardware version of the car: Older Teslas might require a computer upgrade to be compatible with the latest FSD software. This upgrade (referred to as FSD Computer 3.0) is usually included in the FSD purchase price, but it’s important to confirm this before you commit.

You also have the option of an FSD subscription, priced around $99 per month (again, as of late 2024) if your car has FSD Computer 3.0. This can be a more palatable option for some, allowing you to try FSD without the hefty upfront cost. However, over the long term, the subscription model can end up being more expensive than the one-time purchase.

How to Check Your Tesla’s Autopilot Configuration

Knowing exactly what Autopilot features your used Tesla already has is crucial. Here’s how to check:

On the car’s touchscreen: Navigate to Controls > Software > Additional Vehicle Information. This screen will show you which Autopilot options are enabled.
Tesla Account: Log in to your Tesla account on the Tesla website or app and look at the “Manage” section for your car. The details of your car’s configuration should be displayed.
Original Window Sticker (Monroney Label): If you have access to the original window sticker, it will list all the options that were originally purchased with the vehicle, including Autopilot and FSD.

The FSD Computer Upgrade: What You Need to Know

As mentioned earlier, older Teslas (typically those manufactured before April 2019) might need a computer upgrade to run the latest FSD software. This upgrade replaces the existing Autopilot computer with the FSD Computer 3.0, a more powerful processor capable of handling the complex calculations required for autonomous driving.

The FSD Computer 3.0 upgrade is usually included in the purchase price of FSD (either the one-time purchase or the subscription), but it’s essential to confirm this with Tesla before proceeding. The upgrade involves scheduling a service appointment, and a Tesla technician will replace the computer.

The Transferability of FSD

One crucial factor to consider when buying a used Tesla with FSD is whether FSD transfers to subsequent owners. Historically, FSD was tied to the car, not the owner. However, Tesla has experimented with temporary FSD transfers during limited-time offers, allowing owners to transfer FSD to a new Tesla upon purchasing one.

Currently, FSD is generally not transferable to another Tesla. If you sell your used Tesla, the FSD capability stays with the car and could increase its resale value. But you cannot transfer it to a new Tesla you buy.

Frequently Asked Questions (FAQs) About Adding FSD to a Used Tesla

1. Will adding FSD significantly increase the resale value of my used Tesla?

Yes, adding FSD (or having it already installed) will likely increase the resale value of your used Tesla. While the exact amount varies depending on market conditions and the overall condition of the car, FSD is a highly desirable feature that can attract more buyers and command a higher price.

2. Can I finance the purchase of FSD when buying a used Tesla?

Yes, many lenders will allow you to include the cost of FSD in your auto loan when purchasing a used Tesla. Check with your lender to confirm their specific policies and requirements.

3. Is the FSD subscription a better deal than buying FSD outright?

It depends on your individual circumstances. The subscription allows you to try FSD without a large upfront investment. If you only plan to use FSD occasionally, the subscription might be more cost-effective. However, if you plan to keep the car for several years and use FSD frequently, buying it outright is generally the more economical option.

4. What happens to my FSD subscription if I sell my Tesla?

The FSD subscription is tied to your Tesla account. If you sell the car, the subscription ends with the car’s current ownership and does not transfer to the new owner. If you buy another Tesla, you would need to start a new subscription (or purchase FSD outright).

5. How reliable is Tesla’s Full Self-Driving?

While FSD is a cutting-edge technology, it’s important to remember that it’s still under development and requires driver supervision. It is not a fully autonomous system and requires driver attention at all times. Its reliability can vary depending on road conditions, weather, and the complexity of the driving environment.

6. How do I activate FSD after purchasing it for my used Tesla?

After purchasing FSD through the Tesla app or website, it usually activates automatically within a few hours. You might need to restart the car’s touchscreen for the changes to take effect.

7. Will Tesla release more advanced versions of FSD in the future, and will they be included in my purchase?

Tesla is constantly working on improving FSD. Future software updates with enhanced capabilities are generally included as part of your FSD purchase or subscription. However, major hardware upgrades might require an additional cost in the future.

8. Is FSD available in all countries?

No, FSD availability varies depending on the country and regulatory approvals. Check the Tesla website or contact Tesla directly to confirm FSD availability in your region.

9. What are the ethical considerations of using Full Self-Driving?

The use of FSD raises several ethical considerations, including responsibility in the event of an accident, the potential for job displacement among professional drivers, and the impact on traffic flow and safety.

10. Can I test drive a used Tesla with FSD before buying it?

It depends on the seller. Some dealerships or private sellers might allow you to test drive a used Tesla with FSD. However, it’s essential to understand that you are still responsible for the car’s operation and safety during the test drive.

11. What’s the difference between Tesla Vision and cars with radar?

Older Teslas used a combination of radar and cameras for Autopilot. Newer Teslas utilize “Tesla Vision,” a camera-based system only. There has been heated debate about the efficacy of both, with Tesla doubling down on Vision-only systems.

12. Where can I find the latest information on FSD and its features?

The best sources for the latest information on FSD are the Tesla website, the Tesla app, and official Tesla announcements. Be wary of unofficial sources and always verify information with Tesla directly.

Adding FSD to a used Tesla can be a significant investment, but it can also enhance your driving experience and potentially increase the car’s resale value. By understanding the different Autopilot options, the cost of FSD, and the potential need for a computer upgrade, you can make an informed decision and enjoy the benefits of Tesla’s advanced driver-assistance technology.
