Used Volvo S90 1st Gen (2017-2025): Buyer's Guide

Volvo just killed the S90 in the US. Not a redesign, not a rebadge: the tariff on Chinese-built vehicles made a 1,364-unit-a-year sedan built in China commercially pointless, so after model year 2025 it's gone from American showrooms for good. Europe and China keep getting a newer, more heavily updated S90. You don't. That makes every used S90 on a US lot the last generation you'll ever be able to buy new-adjacent, and it changes what "which year should I get" actually means.

This is the first generation, and the only one sold here: 2017 through 2025, built on Volvo's SPA platform alongside the XC90 and V90. It got one real mid-cycle shuffle in the US, in two separate steps people online tend to conflate into one. Get the steps right and the rest of the buying decision gets a lot easier.

It's also worth saying up front what this car is actually good at, because the complaint threads below can make it sound worse than it drives. Seat comfort is the single most consistently praised thing across Edmunds, KBB, and JD Power owner reviews, the kind of praise that specifically mentions multi-hour road trips. Rear legroom beats the BMW 5 Series and Mercedes E-Class it's cross-shopped against in more than one review. Even What Car?'s UK reliability writeup, which ranks the S90 near the bottom of its class for dependability, still calls it "spacious, comfortable and refined" and a good value used buy. Owners seem to agree: 93% of 2018 S90 owners surveyed by KBB said they'd recommend it, despite the same generation carrying real documented mechanical issues. This is a car people who own it tend to like, complaints and all.

This Generation at a Glance

Volvo launched the US S90 for model year 2017 on the SPA platform, sharing its bones, turbo-plus-supercharged 2.0-liter engine family, and PHEV hardware with the XC90. Two changes matter more than the rest. First, MY2021 brought a styling and interior refresh: revised front bumper, new LED taillight signature, a wool upholstery option, wireless charging, and more USB-C ports. The engines didn't change. Second, MY2022 brought the real powertrain shift: the T6 became the mild-hybrid B6, and Sensus infotainment was replaced by a Google-based Android Automotive system with Google Maps and Assistant built in. Those are two different years for two different changes, and used listings mix them freely.

MY2023 brought a trim shuffle: Momentum became Plus, Inscription became Ultimate, and R-Design was dropped entirely. A used-car search filtered by trim name will silently miss half the generation if you only search one naming era.

The T5 FWD entry model disappeared after MY2019; from MY2020 on, every US S90 is AWD. The 8-speed Aisin automatic is the only transmission across all nine model years and every engine.

Powertrain & Trim Breakdown

T5 (2017-2019): the one nobody remembers exists

The base FWD engine is a plain 2.0-liter turbo-4 with no supercharger and no PHEV hardware attached. It's the least discussed S90 online for a simple reason: almost nobody bought it. Volvo dropped it after MY2019 and never brought it back. What owners like about it: less complexity, less to fail, and the same comfortable cabin and seats as every other S90 for less money up front. If you find one cheap and don't care about AWD, it's the simplest car in this whole guide, and the one with the thinnest complaint history because there's less machinery to complain about. The tradeoff is resale and community support; parts and forum knowledge skew heavily toward T6 and T8 owners, so a T5-specific problem is more likely to go unanswered on a forum search.

T6 (2017-2021): the volume engine, and where the real problems live

The T6 adds a supercharger on top of the turbo for a genuinely quick, genuinely complicated engine. Two issues show up again and again in owner threads. First, fuel dilution in the oil: SwedeSpeed owners running independent oil analysis have reported dilution readings from 3.3% up to 10% on this Drive-E engine family, a known short-trip issue on direct-injection turbos where unburned fuel washes past the rings into the crankcase. Volvo's own guidance is to let the engine run 10-plus minutes after a cold start rather than short-hopping it constantly. Second, the Aisin 8-speed automatic. CarComplaints logs the 2018 model year at 21 owner-reported problems, with transmission issues as the single most common complaint category and "transmission died" reported at an average of roughly 12,000 miles in the worst cases. Forum threads describe rough shifts, hesitation on acceleration, and gear jumps straight from Drive to Park right after startup, the last of which was significant enough that Volvo issued a technical service bulletin for it. The complaint cluster concentrates in 2017-2018; later T6 years show fewer transmission threads.

Steering wheel module failures come up repeatedly on SwedeSpeed too, usually voice command or radio controls going dead within the first year of ownership. It's not in NHTSA's recall data, so treat it as a documented forum pattern rather than a safety recall. What owners actually like about the T6: it's genuinely quick for a family sedan, the supercharger fills in the low-end torque the turbo alone can't, and the cabin stays quiet even when you're using all 316 horsepower.

T8 Twin Engine, 2018-2021: fast, and the battery won't stay fast

The T8 pairs the T6's hardware with a 10.4-kWh battery and a rear electric motor for 400 hp combined and an EPA-rated electric range around 21 miles when new. That range does not hold. Owners across the SPA platform (S90, XC60, and XC90 all share this drivetrain, so the pattern isn't S90-exclusive) report meaningful degradation: one 2017 T8 owner saw range fall from 21 miles to as low as 16, with actual driving range reported closer to 9 miles despite a 16-mile dashboard reading. Another owner's T8 dropped to an 18-mile max at just 12,000 miles and 14 months of ownership. A battery energy control module software update has resolved display-reading discrepancies for some owners, but that's a recalibration, not a capacity fix. If you're shopping a T8, ask for a full-charge range test before you buy, not after.

There's a real safety recall here too: campaign 25V179000 covers 2020-2021 T8 models for a high-voltage battery that can short-circuit internally when fully charged and parked. Confirm any 2020-2021 T8 you're considering has had this remedy completed before you buy it, and only take a dealer's word for a specific VIN, not a blanket "recalls are all handled" assurance.

Charging is slow by modern EV standards: a full charge on a standard household outlet runs around 5 hours, and even a proper Level 2 charger takes 3-plus hours for a 10.4-kWh pack. That's normal for a PHEV of this vintage, but it surprises buyers expecting EV-like convenience. What owners like: for anyone with a short commute, running most daily miles on electricity while still having 400 hp and a full tank of gas for a road trip is exactly the pitch it sounds like, and cabin refinement doesn't take a hit for carrying the extra hardware.

B6 (2022-2025): smoother, slightly less powerful, still turbo

The MY2022 switch to B6 badging isn't just marketing. A 48-volt mild-hybrid starter-generator replaces the old system, smoothing out stop-start and nudging fuel economy up slightly, in exchange for peak output dropping from 316 hp to 295 hp. It's the same fundamental engine architecture as the T6, so the fuel dilution pattern documented above applies here as well, though forum complaint volume is noticeably lower for 2022-and-newer cars than for 2017-2018 T6s. The bigger change for daily use is the switch from Sensus to Google's Android Automotive infotainment the same model year, which fixes the old system's tendency to freeze the display, radio, and turn signals simultaneously. It also introduces a new problem: a class-action lawsuit covering 2022-2025 S90 models (among other Volvo models) alleges infotainment malfunctions including frozen displays, lost backup camera feeds, and dropped Bluetooth audio. Test every screen function on a pre-purchase inspection regardless of model year. What owners like about the B6: it's noticeably smoother off the line than the old T6 thanks to the mild-hybrid assist filling in turbo lag, and Google Maps and Assistant built into the dash are a real upgrade over Sensus for anyone who found the old system clunky.

T8 Recharge and T8 Recharge Extended Range (2022-2025): the power jump nobody advertises loudly

MY2022's T8 Recharge carries over the prior generation's 400 hp. MY2023 is where it gets interesting: Volvo swapped in a more powerful rear motor, 143 hp versus the old 87 hp, pushing combined output to 455 hp and 523 lb-ft, with a claimed electric-only range up to 41 miles in Pure mode. That's a real, meaningful upgrade over the pre-2023 T8, not a trim reshuffle. The battery degradation pattern documented for the earlier T8 is a shared-platform issue, so it's reasonable to expect it applies here too, though there's less accumulated mileage and fewer owner reports on the Extended Range pack specifically since it's newer. What owners like: 455 hp and 523 lb-ft in a comfortable four-door sedan that can also run most errands on electricity alone is a genuinely unusual combination, and it's the closest this generation gets to a sleeper performance car.

Trim Levels

Volvo also sells a Polestar Engineered software package on T6/T8 AWD models. It's a throttle, shift-timing, and off-throttle response recalibration developed with Polestar's engineering team, not a hardware suspension or brake upgrade. Don't pay a premium for it expecting stiffer springs or bigger brakes; you're paying for a different personality, not different parts.

One detail that surprises buyers: the S90's air suspension, when optioned, is rear-only. There's no full four-corner setup like some larger Volvos offer. If ride height and cushioning matter to you, don't assume "has air suspension" means the same thing it does on a bigger SUV.

If you're cross-shopping trim names across model years, remember the MY2023 rename: a used listing for "Momentum" and one for "Plus" can be the same trim level under different badges depending on which side of that year you're looking at, and the same goes for Inscription and Ultimate. Don't assume a Plus-trim 2023 is a step down from an Inscription-trim 2022; it's roughly the equivalent car under new nomenclature.

Which Model Years to Target Within This Gen

Recall counts above come from NHTSA's own recall database for the base US-market S90 (NHTSA also indexes recalls for the China-only long-wheelbase "S90L," which is a different car sold to a different market; those are excluded here).

2021 is the sweet spot if you want the lowest price for a fully sorted first-half-of-generation car: fewest recalls of any year, the styling refresh, and a powertrain that's been in production long enough for the worst early bugs to shake out. 2023 or 2024 is the pick if you want the newer infotainment and either the smoother B6 or the genuinely quicker Extended Range T8. Be cautious on 2017-2018: that's where the transmission complaint cluster and the thinnest powertrain lineup overlap. 2025 carries the newest recall (window/glazing, campaign 25V104000) and, as the final US model year, the smallest used supply so far; there's nothing wrong with it mechanically, but you're paying a premium for a car that's barely depreciated yet.

Pre-Purchase Inspection Checklist

Every S90, regardless of engine:

• Test every touchscreen function, the backup camera, turn signals, and Bluetooth audio during the test drive. Both the old Sensus system and the newer Android Automotive system have documented freeze and dropout complaints.
• Test all steering wheel controls, especially voice command and radio buttons. Failures here show up within the first year on some cars and aren't always obvious from a quick glance.
• Feel for vibration in the brake pedal at speed and listen for grinding backing out of a driveway; rear rotor and pad wear come up repeatedly in owner reports.
• Check tire wear patterns for high-speed shimmy history, especially on cars still riding on original-fit Pirelli run-flats.
• If the car has rear air suspension, cycle it through comfort and dynamic modes and listen for knocks.

T6 and B6 (non-hybrid AWD):

• Ask for a recent oil analysis or at minimum check the oil level and smell for fuel odor on the dipstick. Fuel dilution is a documented issue on this engine family.
• Start the car cold if you can and watch for hesitation or a hard jump from Drive to Park.

T8 Twin Engine and T8 Recharge (PHEV):

• Fully charge the car and drive it on battery only to check actual electric range against the window sticker figure. A meaningful shortfall is common enough to budget for, not a dealbreaker on its own, but it should affect the price you're willing to pay.
• For 2020-2021 models specifically, confirm campaign 25V179000 (high-voltage battery short-circuit risk) has been completed. Get the VIN-specific confirmation, not a general assurance.
• Ask whether the charging cable has habitually been left plugged in after a full charge; some owners link this to accelerated 12-volt battery drain.

Run every VIN through a recall check before you commit, and confirm any open campaign has actually been completed rather than just scheduled.

Running Costs

Independent tracking from TrueDelta's owner-reported repair data puts electrical and A/C issues at roughly a third of all reported S90 repairs, with engine, brakes and traction control, and paint/trim/leak issues splitting most of the rest evenly. RepairPal lists brake rotor vibration and a coolant temperature sensor triggering false no-start warnings among the most common named repairs. None of this is alarming on its own; it's a normal luxury-sedan repair mix, weighted toward electronics the way most modern cars with this much technology are.

FAQ

Is the Volvo S90 T6 reliable? The T6 engine itself holds up, but the Aisin 8-speed automatic shows a real complaint cluster in 2017-2018 models, including CarComplaints' worst-reported year at 21 logged issues. Later T6 and B6 years show fewer transmission threads. Budget for a pre-purchase transmission check regardless of year.

What year Volvo S90 should I avoid? 2017 and 2018 combine the thinnest powertrain lineup, the highest recall count (2017, at 4), and the transmission complaint cluster documented on CarComplaints and SwedeSpeed. They're not unsafe, but they carry the most documented risk of this generation.

How much range does a used Volvo S90 T8 actually have? Less than the window sticker claims once the battery ages. Owners report EPA-rated 21-mile ranges dropping to 16 miles or lower within the first 12,000-40,000 miles across the shared SPA-platform T8 drivetrain. Always test actual charged range before buying, not the dashboard estimate alone.

Does the Volvo S90 have air suspension? Only as an option, and only on the rear axle. It's not a full four-corner system like larger Volvos offer, so don't expect SUV-level ride adjustability.

Why is the Volvo S90 being discontinued in the US? The US-market S90 is built in China, and tariffs on Chinese-built vehicles made continuing to sell a low-volume sedan (1,364 units in 2023) commercially unworkable. Volvo unveiled a newer, more heavily updated S90 for 2026, but it isn't coming to the US, Canada, or Australia. Model year 2025 is the last one sold here.

Bottom Line

The 2021 model year is the value pick: fewest recalls of any year in this generation, a fully sorted powertrain, and the styling refresh without the B6/infotainment growing pains that came a year later. If you want the newer tech and don't mind paying more, 2023 or 2024 gets you the smoother B6 or the genuinely quicker 455-hp T8 Recharge Extended Range. Whatever year you land on, get a full-charge range test on any T8 and a cold-start transmission check on any T6, and run the VIN through a recall check before you sign anything. With no newer US-market S90 coming to replace it, this generation is the last word on the nameplate here, which makes parts and dealer support longevity worth thinking about if you're planning to keep one past the decade mark. CarScout tracks S90 listings against your exact spec and price range daily if you'd rather not comb through every dealer site yourself.
