Used Tesla Model S or X with FSD: the older-hardware traps, Supercharging and Luxe Package, and what to check

The Model S and X are no longer made

Elon Musk said on Tesla's January 28, 2026 earnings call that "it's time to basically bring the Model S and X programs to an end with an honorable discharge" (Motor1). Electrek reported on April 1, 2026 that custom orders had ended, with roughly 600 new cars left worldwide, nearly all in the US (Electrek). Tesla posted on May 10, 2026 that "The last Model S & the last Model X have been produced at Fremont Factory" (Jalopnik, May 15, 2026).

The last run was a 350-car Signature Edition (250 Model S, 100 Model X), all Plaid with the Luxe Package, whose buyers reportedly signed a one-year no-resale agreement with a Tesla right of first refusal on later resales (Not a Tesla App, May 9, 2026). The coverage we read does not say how long Tesla will supply parts or service, so ask Tesla about the specific car before you rely on that. For a buyer the result is simple: the used pool is finite, and a Signature Edition offered for sale in its first year is worth extra questions.

The Autopilot computer by build date

Model S and X were built with four generations of self-driving computer. The dates below are approximate and come from press coverage and Wikipedia; the screen is the only reliable answer. Open Controls > Software, then Additional Vehicle Information, and read the Autopilot computer line (Tesla's own instruction on its AI computer page).

Sources: Wikipedia, Tesla Autopilot hardware for HW1 to HW2.5; TechCrunch, April 22, 2019 (Musk: Tesla switched the Model S and X to its own chip "about a month ago"); Not a Tesla App ("you'll likely have AI4 if you purchased after March 2023"; Wikipedia says HW4 shipping began in January 2023).

The HW2 and HW2.5 catch

Tesla's AI computer page says: "If you purchased Full Self-Driving (Supervised) and have computer 2.0 or 2.5, you are eligible for a complimentary upgrade to the Full Self-Driving computer 3.0." It adds that a complimentary upgrade "is not available for Full Self-Driving (Supervised) subscriptions; however, you may be eligible to upgrade" at your own cost: $1,000 plus tax on the US page (May 14, 2026 capture) and $1,500 plus tax on the Canadian page (May 12, 2026 capture). Early computer 2.0 cars may also get complimentary camera replacements. The page does not say whether the free upgrade follows the car to a second owner or has a deadline, so ask for proof that the upgrade was done and read the Autopilot computer line yourself. The same rules apply to a subscribe-later buyer in Can you add FSD to a used Tesla?

HW3 cars: what they run

FSD (Supervised) v14.2 Lite reached redesigned (2021 and later) HW3 Model S and X from September 23, 2026 (Not a Tesla App). On October 14, 2026 Tesla began sending v14.3 Lite to the older "Intel-powered" HW3 S and X, without Arrival Options, starting FSD from Park, reversing on FSD or Smart Summon (Not a Tesla App). The whole HW3 picture, including Tesla's statements on unsupervised driving, is in HW3 vs HW4 (AI4) and Can a Tesla with HW3 be upgraded to AI4?.

The infotainment computer (MCU1, MCU2, MCU3)

The Autopilot computer and the touchscreen computer are different parts, and the older S and X have the older touchscreen computer:

• MCU1: an NVIDIA Tegra-based unit (Teslarati, March 3, 2020) in Model S and X built through about March 2018. When Tesla launched a paid Infotainment Upgrade in March 2020 it was offered to "Model S and Model X built March 2018 or earlier" at $2,500, and it "removes AM, FM and Sirius XM radio" (Electrek, March 2, 2020). Reported later prices differ, so confirm the current price with Tesla if a seller says it was done.
• MCU2: Intel Atom-based. It debuted in the Model 3 in 2017, came to new Model S and X after MCU1, and was used through 2022.
• MCU3: AMD Ryzen-based, first in the refreshed Model S and X that debuted in 2021 (Not a Tesla App, February 18, 2025). MCU2 cars lack some features, such as a full 3D park-assist view.

What this means for FSD is the unsettled part. Tesla Oracle reported in August 2024 that FSD v12.3.6 reached MCU1 Model S and X (Tesla Oracle, August 21, 2024), and the 2026 Lite rollouts above were reported for Intel-powered and redesigned cars; we found no Tesla statement on what an MCU1 car can run today. So treat an MCU1 car as one where you must see current FSD (Supervised) working on a test drive, not assume it. To read the infotainment processor, go to the same Software > Additional Vehicle Information screen (Not a Tesla App); Tesla's own AI computer page names the two older types as "Intel Atom" and "NVIDIA Tegra".

Owned FSD, Luxe Package and what Tesla's own stock shows

• Purchased FSD on an older car stays with it. Tesla's resale wording: "If the previous owner purchased FSD (Supervised) outright and did not transfer it to a new vehicle, you will receive the vehicle with FSD (Supervised)" (Tesla, July 14, 2026 capture). A seller who moved FSD to a newer Tesla under the transfer program, which ended March 31, 2026, no longer has it.
• 2026 cars came with the Luxe Package, and under Tesla's current terms its FSD ends at sale. Tesla's terms for the package: "The Full Self-Driving (Supervised), Free Supercharging and Premium Connectivity will not transfer with the vehicle and will terminate once the ownership of the Model S, or Model X is transferred" (Tesla Luxe Package terms). Not a Tesla App reported that packages ordered before February 14, 2026 kept their FSD with the car. That makes the order date the first question on any 2026 car; see Does FSD transfer to a new owner?
• Subscriptions never come with the car. The new owner subscribes on their own Tesla Account, $99 a month on Tesla's page.

FSD Radar studied Tesla's archived used-inventory data from 2020 to 2025 (method in Tesla CPO cars and FSD). It covers only cars Tesla itself resold, not private sellers or independent dealers.

Later captures lean toward cheaper cars, but the pattern is the one that guide describes for every model: Tesla's resold stock lost its FSD. That guide also shows two used Model S that Tesla listed with FSD at $50,600 (2017 car, May 2023) and $48,900 (2018 car, June 2023) and later re-listed with basic Autopilot at $41,400 and $42,300. An S or X that still has owned FSD is therefore mostly a private-seller or independent-dealer find (where to find a used Tesla with FSD).

Free Supercharging

This is where Model S and X listings go wrong most often, because the app shows free Supercharging the same way whoever it belongs to. What we can and cannot confirm:

• Luxe Package Supercharging does not transfer. Tesla's Luxe terms list it as "(not transferable)" and say it ends at transfer.
• Tesla's resale data rarely shows any. In the archived Tesla used-inventory data, no car carried the older free-unlimited code $SC01, and only 37 Model S rows (all 2016 to 2018 cars in 2020 captures) carried $SC05, the free-unlimited code; Tesla resold almost everything as pay-per-use ($SC04). The codes are explained in Tesla option codes for FSD.
• Early lifetime free Supercharging on private sales. Owner reports and community code lists say it passes to a private buyer on the earliest cars, but not when Tesla buys a car back and resells it. We could not find that rule on a Tesla page, and the coverage we read does not state it either. In October 2023 Tesla let owners move their free unlimited Supercharging to a new car (Drive Tesla Canada, October 20, 2023), so a seller may have moved it away.

Practical rule: price the car as if there is no free Supercharging, and count it as a bonus only if Tesla confirms in writing, for that VIN and your account, that it stays.

A checklist for the Model S or X in front of you

1. Build date and VIN. Run the VIN through the free Tesla VIN decoder for model year and factory; then read the real hardware on the screen.
2. Autopilot computer line. 2.0 or 2.5 means ask for proof of the upgrade, or add its price. HW3 means Lite. AI4 means the main branch.
3. Infotainment processor. NVIDIA/MCU1 or Intel/MCU2: see FSD (Supervised) running on that exact car before paying for it.
4. FSD owned, subscribed, Luxe or transferred? Controls > Software should list "Full Self Driving Capability" (Tesla's own check). Then ask the seller for the order paperwork or an app screenshot (how to check a Tesla for FSD). For a 2026 car, ask for the Luxe Package order date.
5. Free Supercharging. Ask which kind it is and who confirmed it. Assume it ends at sale unless Tesla says otherwise.
6. Signature Edition or very new car. Ask about the no-resale agreement and who is selling.
7. Drive it on FSD with the seller present, then compare the price against the break-even rule.

More seller questions are in questions to ask a Tesla seller about FSD.
