Volvo S90 Best & Worst Years (2026 Edition): Full Reliability, Costs & Buying Guide
📖 1. Definition: What Is Volvo S90?
The Volvo S90 is a full-size luxury executive sedan, produced since 2016 (2017 model year). Built on Volvo’s scalable SPA platform, it embodies Scandinavian luxury, minimalist design, and world-leading safety. Competes directly with Audi A6, BMW 5 Series, Mercedes E-Class, Genesis G80. The “best and worst years” classification refers to model years where reliability, owner satisfaction, repair frequency, and resale value peak (best) or dip significantly (worst).
Why this matters: Choosing a bad year could cost you $3,000+ in extra repairs; picking a best year delivers Volvo’s true premium experience. Below we dissect every model year with data from NHTSA, J.D. Power, and real owner forums.
🏷️ 2. Types / Generations & Powertrains
Pre-facelift (2017–2020): T5 (turbo 2.0L 250hp), T6 (turbo+super 316hp), T8 plug-in hybrid (400hp). Sensus infotainment. Facelift (2021–present): B5/B6 mild-hybrid (295hp/316hp), Recharge T8 (455hp). Google built-in (2022+). Trims: Core, Plus, Ultimate (formerly Momentum/Inscription). Best years = facelift with mild-hybrid smoothness and Google OS stability.
2022+ B6 / Recharge
Google Automotive, OTA updates, improved electric range (41mi T8), no major mechanical flaws.
2017-2018 T6/T8
Supercharger whine, evaporator failures, early hybrid battery issues, slow infotainment.
❌ 3. Why 2017–2018 Are The Worst Years (Deep Dive)
Infotainment nightmare: Sensus system freezes, random reboots, slow boot-up time. Air conditioning evaporator leaks – a $2,200 repair common around 40k-60k miles. T6 engine oil consumption due to piston ring design, leading to carbon buildup. Transmission hesitation (8-speed Aisin) on downshifts. Also multiple recalls: seatbelt anchor (2017), fuel pump module (2018), coolant hose detachment. These years saw 2.5x more complaints than 2020+ models. If you must buy, ensure all TSBs done, but strongly advised to avoid.
✅ 4. Why 2020–2023 Are The Best Years (Proven Excellence)
Volvo addressed virtually all early faults: updated A/C evaporator design (2020+), advanced infotainment processor, refined engine mounts, improved hybrid cooling. The 2020 model introduced acoustic laminated glass, lower NVH, and upgraded Pilot Assist. From 2021, mild-hybrid (B5/B6) eliminates supercharger on B6 and provides smoother start/stop. 2022+ gets Google built-in – responsive, never lags. Data shows 2021+ S90 has below-average luxury sedan repair frequency. J.D. Power 2023 APEAL score: 85/100. 2024-2025 carry same strengths.

⚖️ 6. Advantages (Best Years) vs Disadvantages (Worst Years) – Detailed
✨ Advantages – 2020+ S90
- ✔ Class-leading safety: IIHS Top Safety Pick+ every year
- ✔ Minimal repair frequency: 0.3 issues/vehicle vs 1.5 on 2017
- ✔ Excellent resale: retains ~58% after 3 years
- ✔ Luxury interior with sustainable materials, Bowers & Wilkins optional
- ✔ Low cost of ownership (brakes last 50k+ miles)
⚠️ Disadvantages – 2017-2018 S90
- ✖ Costly evaporator core replacement (up to $2,500)
- ✖ Frequent electronics: camera failures, parking sensor errors
- ✖ T8 battery replacement can exceed $8,000 if out of warranty

🛒 7. How To Choose A Reliable Volvo S90 (Step-by-Step)
Step 1: Target 2020+ models – B5/B6 engine recommended for simplicity. Step 2: Run VIN recall check on NHTSA website. Step 3: Pre-purchase inspection focusing on A/C, suspension bushings, and infotainment responsiveness. Step 4: Avoid any 2017/18 with incomplete service history. Step 5: Prefer CPO (Certified Pre-Owned) from Volvo – includes 5-year/unlimited-mile warranty. For T8 hybrids, prioritize 2021+ to avoid early battery woes. How to test drive: listen for supercharger whine (T6), check for AC cold air, shift through all gears smoothly.
🛡️ 8. Is Volvo S90 Safe? (All Years Analysis)
Yes, exceptional safety across all years. Even the worst 2017 S90 earned IIHS Top Safety Pick+ with good ratings in all crash tests. Standard features: City Safety (auto brake), Run-off Road Mitigation, Large Animal Detection. Best years (2020+) add Steering Support for oncoming avoidance, Cross Traffic Alert with auto brake, and advanced Whiplash Protection. NHTSA 5-star overall rating. No safety degradation in worst years; only reliability differs. So if safety is your only concern, any S90 is great, but 2020+ provides extra driver assists.
💰 9. Real Ownership Costs: Worst vs Best Years (5 Year Total)
2017 Volvo S90: average annual repair + maintenance ~$1,850 (including unexpected A/C, infotainment module). 2022 Volvo S90: average annual ~$650 (routine oil, filters, brake fluid). That’s a $6,000 difference over 5 years. Also insurance rates similar, but worst years may have slightly higher comprehensive due to parts failure risk. Best years also get better fuel economy (mild hybrid: 30 MPG highway vs 26 MPG on older T6).
🧳 10. Best Use Cases for Volvo S90 (By Year)
Best years (2020+) – ideal for daily commuting, executive shuttle, long-distance touring, and family hauling with supreme comfort. Worst years (2017/18) – only recommended as a project car or if you have a warranty and independent Volvo specialist. Avoid for rideshare or high-mileage driving due to potential downtime.
