You're looking at a used EV. It’s a minefield out there. Honestly, the 2017 Tesla Model S 90D might just be the most misunderstood car in the company's entire timeline. It sits right in that weird transition period. Tesla was moving from the old "nose cone" look to the sleek, body-colored front fascia. It was also the year they played musical chairs with Autopilot hardware. If you buy the wrong month, you’re stuck with old tech. If you buy the right one, you’ve got a bargain supercar.
It's fast. Like, "make your stomach drop" fast, even without a P badge.
People obsess over the P100D because of the 0-60 times that make your vision go blurry. But the 90D? It’s the one you actually want to live with. It offered a realistic 294 miles of range when it was new. In the real world, seven years later, you're likely seeing a bit of degradation, but it still outpaces many brand-new budget EVs.
What the 2017 Tesla Model S 90D gets right (and wrong)
Let’s talk about the battery. The 90kWh pack has a bit of a reputation. Early versions of this pack (the "v1" and "v2") were known to throttle charging speeds at Superchargers if they were DC fast-charged too often. Owners called it "Chargegate." It’s annoying. You pull up to a 250kW stall and the car only pulls 90kW. But by 2017, Tesla had refined the chemistry significantly. If you're looking at a 2017 model, you’re likely getting the better version of that 90kWh architecture compared to the 2015 units.
The 90D is dual-motor. That’s what the "D" stands for, obviously.
It’s planted. Heavy, sure, but the center of gravity is so low it feels like it’s velcroed to the asphalt. You get 417 horsepower and 485 lb-ft of torque. It hits 60 mph in about 4.2 seconds. In 2017, that was faster than most Porsches on the road. Today, it still beats a base Model 3 at a stoplight.
The Autopilot Gamble
This is where it gets confusing for buyers. 2017 was the "crossover" year. Cars built early in the year might have Autopilot 2.0 (HW2), while later ones got 2.5. Why does this matter? Because if you want Full Self-Driving (FSD) to actually work well, you need the processing power.
Luckily, Tesla offered retrofits.
If you find a 2017 Tesla Model S 90D with the "Full Self-Driving Capability" package already paid for, you can often get the computer upgraded to HW3 for free if it hasn't been done already. That is a massive value add. You’re getting a car that learns new tricks every few months via software updates. It’s the only seven-year-old car on the planet that actually gets better the longer you own it.
Interior Quality: The Elephant in the Room
Tesla interiors from this era are... polarizing. You either love the minimalism or you hate the "IKEA on wheels" vibe. In 2017, they were still using the "Next Generation" seats which are actually quite comfortable, though they lack the side bolstering of the newer Plaid seats.
The screen. Oh, the screen.
The vertical 17-inch display in the 2017 Tesla Model S 90D is prone to "yellow borders." It’s a UV glue issue. It looks like a tea stain around the edges of your map. Tesla eventually offered a fix for this, but many used units still have it. Also, check if the MCU (Media Control Unit) has been upgraded to MCU2. The original MCU1 used an eMMC chip that will fail. It makes the screen laggy and eventually it just goes black. If the previous owner upgraded to Intel Atom (MCU2), the car will feel snappy, support Netflix, and have a much more reliable brain.
Real World Range and Charging Realities
You aren't getting 294 miles. Stop dreaming.
After 60,000 or 80,000 miles, a 90kWh battery typically settles around 6-8% degradation. Expect about 260-270 miles on a full charge if you’re driving like a sane person. If you're doing 80 mph on the interstate in the winter? Cut that down to 200. That’s just physics. Cold air is dense, and heating a cabin with a resistive heater (the 2017 doesn't have the efficient heat pump found in newer Teslas) sucks energy fast.
But here is the kicker: Free Supercharging.
Some 2017 Tesla Model S 90D units still carry "Free Unlimited Supercharging" (SC01 code) that follows the car, not the owner. If you find one of these, your fuel costs are effectively zero for the life of the vehicle. This is the holy grail of used car finds. However, be careful. Tesla started stripping this benefit on cars sold through their own used inventory. Private party sales are your best bet to keep the "free fuel" perk.
Maintenance is weirdly simple
No oil changes. No spark plugs. No timing belts. No transmission fluid flushes.
Basically, you’re looking at tires, wipers, and cabin filters. But—and this is a big but—the door handles. The 2017 Model S has those cool "presenting" door handles that slide out when you approach. They are notorious for failing. A small wire inside snaps, or a plastic gear strips. It costs about $300-$500 to fix at a service center, or $50 if you’re handy with a screwdriver and buy a reinforced kit online.
Also, the air suspension.
Most 90Ds came with Smart Air Suspension. It’s glorious for ride quality. It can remember to raise the nose of the car when you pull into a steep driveway using GPS. But air struts eventually leak. If the car looks like it’s "squatting" after being parked overnight, you’re looking at a $1,500 repair bill per corner. It's a luxury car. Treat it like one.
Comparing the 90D to the 75D and 100D
Why choose the 90D?
The 75D is cheaper but the range anxiety is real. You'll find yourself stopping every 150 miles on road trips. The 100D is the king of range, but it holds its value so well that you'll pay a $10,000 premium for it. The 90D sits right in the middle. It’s the "Goldilocks" zone. You get the 0-60 speed that scares your passengers, enough range to cross state lines without a panic attack, and a price point that has finally depreciated into the "affordable" territory for a high-end luxury sedan.
Essential Checklist for Buyers
If you’re standing in someone’s driveway looking at a 2017 Tesla Model S 90D, do these things immediately:
- Check the MCU version. Go to Software > Additional Vehicle Information. If it says "NVIDIA Tegra," it's the old, slow one. If it says "Intel Atom," it's been upgraded. This is a $2,000 value.
- Look for the yellow screen border. Turn on a white background (like the browser or settings). If there's a yellow ring around the edge, negotiate the price down.
- Test every door handle. Every single one. Twice.
- Check the "C" pillars. Early 2017 models sometimes had issues with the trim pieces peeling or becoming misaligned.
- Run the battery to 100% (once). See what the projected range says. If a 90D shows less than 250 miles at a full charge, that battery has had a rough life.
The 2017 Tesla Model S 90D represents a specific era of Tesla where the build quality was starting to stabilize, but the soul of the car was still very much about disruption. It doesn't have the "blind spot" cameras in the center screen like the new ones (unless upgraded), and the vertical screen feels a bit old-school compared to the horizontal ones in the Model 3, but it has a dedicated instrument cluster in front of the driver. Many people—myself included—actually prefer that.
Actionable Next Steps
If you are serious about buying a 2017 Tesla Model S 90D, your first move is to check the VIN on a site like TeslaFi or Recurrent Auto. These services can sometimes give you a "battery health score" based on data from similar vehicles, which is way more valuable than a shiny paint job.
Secondly, join the Tesla Motors Club (TMC) forums. Search for "90D battery health threads." There is a wealth of crowdsourced data there from owners who have put 200,000 miles on these cars.
Finally, check your local charging infrastructure. While the 90D is great, it shines brightest if you can charge at home. If you rely solely on Superchargers, you might experience the "Chargegate" slowdowns mentioned earlier. Installing a NEMA 14-50 outlet in your garage should be your number one priority before the car even arrives in your driveway. This ensures you wake up every morning with a "full tank" and avoids the headache of public charging altogether.
