Volvo S90 (Second Generation) - A Comprehensive Guide

The second-generation Volvo S90, introduced in 2016, marks a significant departure from its predecessors and a powerful statement from Volvo about their commitment to the luxury sedan market. Positioned as a mid-size luxury car, the S90 aims to compete with established rivals like the BMW 5 Series, Mercedes-Benz E-Class, and Audi A6. This guide will provide a detailed overview of this model, covering its history, key features, common issues, and buying advice to help potential owners make informed decisions.

1. Introduction

Following Volvo's acquisition by Geely, the S90 was one of the first models built on the Scalable Product Architecture (SPA) platform, a modular system designed to underpin a variety of models, from sedans to SUVs. This platform allows for advanced safety systems, modern powertrains (including hybrid options), and a more refined driving experience. The S90 represents Volvo's ambition to elevate its brand image and compete directly in the premium segment.

2. Generations

  • Second Generation (2017-Present):
    • 2017-2021 (Pre-Facelift): Initial launch featuring the T5, T6, and T8 powertrains. The T5 offered a turbocharged 2.0L engine, the T6 added supercharging to the same engine for increased power, and the T8 was a plug-in hybrid. Standard features included the "Thor's Hammer" LED headlights, Volvo's Sensus infotainment system, and a range of safety features.
    • 2021-Present (Facelift): A mid-cycle refresh brought subtle styling updates, primarily to the front and rear bumpers. More significantly, the engine range was refined, with a focus on mild-hybrid technology. The "B" designation replaced the "T" designation to signify the mild-hybrid system. Powertrain changes also involved some retuning for improved efficiency. The rear seats gained a more luxurious design, and the infotainment system received further refinements.

3. Reliability & Common Issues

While the second-generation S90 is generally considered a reliable vehicle, it is not without its potential issues. Here's a breakdown of common problems and areas to inspect:

  • Electronics and Infotainment System (Sensus):
    • Issue: The Sensus infotainment system, while visually appealing, can be prone to glitches, software freezes, and connectivity problems. Common complaints include slow response times, navigation errors, and Bluetooth connectivity issues.
    • Diagnosis & Solution: Ensure the software is up to date. A factory reset can sometimes resolve minor issues. In more severe cases, a visit to a Volvo dealership may be required for software reinstallation or hardware replacement.
  • Air Suspension (Optional):
    • Issue: Models equipped with air suspension (often found on Inscription trims) can experience air leaks, compressor failures, and ride height sensor issues.
    • Diagnosis & Solution: Listen for hissing sounds near the air struts. Inspect the air lines for cracks or leaks. A malfunctioning compressor will prevent the suspension from adjusting properly. Replacement parts can be expensive. Before buying, have the system thoroughly inspected by a qualified mechanic.
  • Turbocharger Issues (T5 and T6):
    • Issue: Turbochargers, particularly in earlier models, have been known to experience premature wear or failure, which can lead to reduced performance and potential engine damage. The T6, due to its supercharger and turbocharger combination, could face issues with either forced induction system.
    • Diagnosis & Solution: Listen for whining or whistling noises from the turbocharger area. Check for oil leaks around the turbocharger. Regular oil changes with the correct synthetic oil are crucial for turbocharger longevity. Inspect the intake pipes and intercooler for any leaks or damage.
  • Engine Issues (2.0L variants):
    • Issue: Although generally reliable, the 2.0L engine (T5, T6, T8 and later B5, B6) can be prone to oil consumption, especially at higher mileages. Carbon buildup on the intake valves (direct injection engines) can also lead to performance issues.
    • Diagnosis & Solution: Regularly check the oil level and be aware of any unusual exhaust smoke. Consider a carbon cleaning service (walnut blasting) every 50,000-75,000 miles. Ensure proper maintenance with high-quality synthetic oil and filters.
  • Battery Issues (T8 and B-designated Mild Hybrids):
    • Issue: The hybrid battery pack in the T8 (Plug-in Hybrid) and the 48V mild-hybrid system in the B-designated models can experience degradation over time, reducing electric range and performance.
    • Diagnosis & Solution: Check the battery health through the car's computer system. Note the range and charging times of the T8. The 48V system, while not providing significant electric range, is crucial for start/stop functionality and engine assist. Battery replacements can be expensive. Have the battery health checked before purchase, especially on older models.
  • Transmission Issues (8-speed Automatic):
    • Issue: The Aisin-Warner 8-speed automatic transmission, while generally reliable, can occasionally exhibit rough shifting or hesitation, particularly at lower speeds.
    • Diagnosis & Solution: Ensure the transmission fluid has been changed according to Volvo's recommended service schedule. A transmission flush can sometimes resolve minor issues. In more severe cases, valve body repair or replacement may be necessary.

4. Driving Experience

The Volvo S90 offers a distinctive driving experience that prioritizes comfort and refinement over outright sportiness. Here's a breakdown of the pros and cons:

  • Pros:
    • Comfortable Ride: The S90 excels in providing a smooth and comfortable ride, especially on models equipped with air suspension. It's well-suited for long journeys.
    • Refined Interior: The interior design is Scandinavian-inspired, with high-quality materials and a minimalist aesthetic. The seats are exceptionally comfortable and supportive.
    • Advanced Safety Features: Volvo is renowned for its commitment to safety, and the S90 is packed with advanced driver-assistance systems, including Pilot Assist (semi-autonomous driving), lane keeping assist, blind-spot monitoring, and automatic emergency braking.
    • Fuel Efficiency (Especially T8/Recharge): The T8 plug-in hybrid offers excellent fuel economy, especially when driven primarily in electric mode. The B-designated mild-hybrids also improve fuel efficiency compared to the earlier T5 and T6 models.
  • Cons:
    • Infotainment System: The Sensus infotainment system, while visually appealing, can be cumbersome to use and lacks the responsiveness of some competitors.
    • Driving Dynamics: While comfortable, the S90 doesn't offer the same level of sporty handling as some of its German rivals. Steering feel can be somewhat numb.
    • Rear Seat Headroom: While legroom is generous, taller passengers may find rear headroom to be somewhat limited, especially in models with the panoramic sunroof.
