You see those doors go up and you think, "That’s it. That’s the future."
Then you look at the price of a brand-new one and realize the future is expensive. Like, six-figure expensive. So, you start scrolling through used listings. You see a 2017 for $24,000 and a 2022 for $65,000 and wonder why the gap is wider than the Grand Canyon.
Buying a used Tesla Model X isn’t like buying a used Lexus. It’s more like buying a pre-owned spacecraft that might need a firmware update or a new set of falcon-wing sensors by Tuesday. If you go in blind, you’re going to get burned. But if you know which VINs to hunt for, you can snag one of the most capable family haulers ever built for a fraction of the original sticker.
The "Raven" Secret and Why 2019 Matters
Most people just look at the battery size. They see "100D" or "75D" and stop there. Big mistake.
The real dividing line in the Model X timeline happened in April 2019. This is when Tesla introduced the "Raven" powertrain. Before Raven, the Model X used an older motor setup that was fine, but a bit clunky. The Raven update brought the permanent magnet motor from the Model 3 to the front axle of the X.
It changed everything.

Suddenly, the car was more efficient. The adaptive air suspension became "smart," adjusting in real-time to the road surface rather than just reacting to speed. If you’re looking at a used Tesla Model X, and the budget allows, you want a Raven. You can identify them by the "Long Range" badging (rather than 100D) and the smoother ride quality. Honestly, the difference in how the suspension soaks up potholes is night and day.
Those Falcon-Wing Doors: Cool or Curse?
Let’s talk about the elephant in the room. The doors.
They are the best and worst part of the car. When they work, you can load a toddler into a car seat in a tight parking spot without breaking your back. It's glorious. When they don't, you're standing in the rain while a sensor insists there's an invisible obstacle above the roof.
On older 2016 and 2017 models, these doors were notoriously finicky. The seals would leak, or the "ghosting" sensors would stop them halfway up. By the time 2020 rolled around, Tesla had mostly ironed this out. If you're inspecting a used one, open and close those doors five times in a row. Listen for grinding. Look for rub marks on the paint where the door might be misaligned. If the seller won't let you cycle them, walk away.
MCU1 vs. MCU2: The Screen Struggle
You might find a 2018 Model X that looks perfect, but the screen feels like an original iPad trying to run modern software.
That’s the MCU1 (Media Control Unit) problem.
Units built before March 2018 came with a processor that eventually starts to lag, freeze, or just die because the memory chip wears out. Tesla offers an upgrade to MCU2 for about $1,500 to $2,000. It’s the best money you’ll ever spend on the car. It adds Netflix, YouTube, and—more importantly—a snappy interface that doesn't make you want to scream.
Always check the "Additional Vehicle Information" tab in the settings. If it says "NVIDIA Tegra," you’re on the old, slow hardware. If it says "Intel Atom," you’re golden. Some people actually prefer the old MCU1 because it keeps the AM radio, which disappears with the upgrade. But for most of us, losing AM is a small price to pay for a map that actually loads.
Battery Life and the 100,000-Mile Cliff
Everyone panics about the battery. "What if it dies?"
Data from the Tesla community shows that Model X batteries usually lose about 10% to 12% of their capacity in the first 50,000 miles, but then they level off. It’s a curve, not a cliff. A used Tesla Model X with 100,000 miles might still have 88% of its original range.
The bigger concern is the warranty. Tesla’s battery and drive unit warranty on the X is 8 years or 150,000 miles (for newer ones) or 8 years/unlimited miles (for older 100D/90D models). If you buy a 2016 today, that warranty is gone or expiring next week. If the high-voltage battery fails out of warranty, you're looking at a $15,000 bill.
This is why the 2021+ "Refresh" models are fetching such a premium. They have the new interior, the horizontal screen, and plenty of warranty left. Plus, the Plaid version is just stupidly fast. 0-60 in 2.5 seconds in a car that weighs 5,000 pounds? It’s physics-defying.
The "Shudder" You Can't Ignore
When you take a used X for a test drive, floor it.
I’m serious.
Many Model X units suffer from a "front-end shudder" during hard acceleration, especially if the suspension is set to "Standard" or "High." This is usually due to the half-shafts being at a weird angle. Tesla has gone through several iterations of these parts, but it’s a recurring theme. If the car vibrates like it’s shivering when you mash the pedal, those half-shafts are likely shot. It’s a known issue, and while it's fixable, it's a great bargaining chip if you're buying from a private party.
Real-World Checklist for Your Inspection
Don't just look at the shiny paint. Focus on the stuff that actually breaks.
- The Panoramic Windshield: Check for tiny chips. Replacing that massive piece of glass can cost $2,500+.
- Tire Wear: The X is heavy and eats tires, especially on the inner edges of the rear wheels due to the camber. If they look bald inside, you're spending $1,500 on new rubber immediately.
- AC Performance: The Model X cabin is huge with a lot of glass. If the AC feels weak, the desiccant bag or the compressor might be on its way out.
- FSD Hardware: Does the car have "Full Self-Driving" computer 3.0? Go to the software tab. If it has 2.5, you'll need a hardware swap to run the latest FSD Beta features.
Actionable Next Steps
If you're ready to pull the trigger on a used Tesla Model X, do not just buy the cheapest one on a random lot. Start by checking Tesla’s own "Used Inventory" page. They often include a 1-year/10,000-mile limited warranty that kicks in after the original expires. It’s a massive safety net.
Next, get a "Battery Health" report. You can actually run a health test yourself in the car's Service Mode (it takes 24 hours and drains the battery to zero), but a simpler way is to look at the "Energy" app and see the projected range at 100% charge compared to what it was when new.
Finally, prioritize 2020 models if you want the best "old-style" interior with the most reliability, or 2022+ if you want the modern tech and can swing the higher price tag. Stay away from the 2016 "Signature Series" unless you're a collector who likes projects. Those early cars are beautiful, but they were essentially beta tests for the rest of the lineup.
