Tesla Model X (2021 on) buying guide

The 2021 Model X came as the Long Range and the new Plaid. The Long Range has a 100-kWh battery and a 360-mile range, with 0-60 mph in 3.8 seconds. The Plaid is rated at 340 miles on 20-inch wheels, and Kelley Blue Book says that falls to 300 miles on 22-inch wheels. Our Model X Plaid market page shows every one for sale, and the Model X ranking among luxury SUVs shows where it stands.

The 2021 car has no Apple CarPlay or Android Auto. Its media computer is an Intel Atom, where the redesigned car has an AMD Ryzen, so ask which you are looking at.

Driver-assist hardware is the bigger question. The 2021 car was built with Autopilot hardware 3.0 and ultrasonic parking sensors. Full Self-Driving was a $10,000 option when new, but tbx.report says it is now sold only as a subscription that ends with the seller, so pay nothing extra for a car that claims to have it. Tesla said in April 2026 that Hardware 3 cannot run unsupervised FSD, and had published no upgrade or trade-in prices or dates as of October 2026. A cut-down FSD v14 Lite has been going to these cars since July 2026.

By year, rerev.com rates the 2021 as OK/Mixed, 2022 as the best second-generation year and 2023 as the worst. Consumer Reports rates the 2021 much less reliable than other cars of its model year, while Yahoo Autos cites an owner score of 4.7 out of five stars. Those two readings point opposite ways, and the sources don't reconcile them.

Air suspension failure

The compressor and struts can fail, and the car drops while parked or fails to raise. Carlyle puts failure at 50,000 to 90,000 miles and the bill at $1,500 to $3,500, while rerev.com quotes $1,000 to $3,000 depending on the problem.

Falcon Wing door faults

Doors can fail to close flush, squeak, rattle, falsely detect obstacles and leak around the seals. Misaligned doors can also hint at an earlier collision.

High-voltage battery wear

The battery can degrade or fail at 100,000 to 200,000 miles, and Carlyle puts the fix at $15,000 to $25,000. The battery and drive unit warranty runs 8 years or 150,000 miles, with at least 70% capacity retained.

Touchscreen replacement

A new screen costs $1,000 to $2,000, says rerev.com. Separately, recall 22V296 covered 2021-2022 Model S and X where fast charging could overheat the infotainment computer, fixed by a free over-the-air update.

Passenger air bag logic

Recall 22V843 covered 2021-2023 Model X cars whose front passenger air bag could deploy incorrectly in low-speed crashes. The fix was a free over-the-air update, so confirm it was applied.

Carlyle lists tire rotation every 6,250 miles and brake service every 12,500 miles or one year. The cabin air filter is due every three years, and brake fluid is tested every four. Battery and drive unit coolant needs no scheduled replacement. A typical year of maintenance runs $651 and five years $2,460, by Carlyle's figures.

Outside the schedule, Carlyle's estimates are $1,500 to $3,500 for air suspension and $15,000 to $25,000 for the high-voltage battery, and rerev.com adds $1,000 to $2,000 for a touchscreen. Check the car's age and mileage against the basic warranty of 4 years or 50,000 miles. Our Tesla Model X price guide shows what the market is doing.

Buy the Plaid whose Battery Health reading, or full-charge range against the EPA figure, shows the pack is holding up, because a failed battery is the $15,000 to $25,000 repair on this car. Pay nothing extra for claimed Full Self-Driving, and do not expect free Supercharging on a used one.

Walk away from any car with a salvage history, since Supercharging can be switched off on it for good. Browse used Model X listings with that in mind, or widen the search with used Teslas for sale.
