Volvo S90 D4 Reliability - Problems & Costs

Volvo's elegant executive saloon and the first car on the new SPA (Scalable Product Architecture) platform alongside the XC90. Powered by the 190 hp D4204T14 twin-turbo diesel driving the front wheels through an 8-speed Aisin automatic. Comfortable and refined, with a strong safety reputation, but reliability in the executive class is well below BMW and Audi rivals - What Car? ranks the S90 22nd of 23 in its segment. Several major recalls affect 2016-2018 cars, including the well-known plastic intake manifold fire risk.· more· less

Buy if: You want a comfortable, distinctive executive cruiser with full service history and verify all recalls (especially intake manifold) have been completed.

Avoid if: You only do short urban trips that will clog the DPF, or you want BMW/Audi-level long-term reliability.

Common Problems

Plastic intake manifold fire risk (recall)

€0 - 1,5001 of 6

Plastic intake manifold can melt and deform, very rare fire risk - covered by recall · more· less

Volvo recalled around 507,000 vehicles worldwide (~70,000 in the UK alone) fitted with the 2.0L diesel built between 2014 and April 2018, including the S90 D4. The plastic intake manifold can melt and deform, causing the check engine light, power loss, engine shutdown, or in rare cases a localized engine bay fire. Volvo replaces the manifold with an upgraded part free of charge under the recall. If recall work has been completed, this risk drops to near zero. If not, schedule it immediately. After the recall fix, oil leaks from the intake manifold and rocker cover area are still occasionally reported - typically €500-1,500 to address at a specialist.

EGR cooler and DPF clogging

€800 - 3,5002 of 6

Soot buildup clogs EGR cooler and DPF, especially on short-trip cars · more· less

The D4204T14 is a clean but emissions-heavy engine. The EGR cooler is prone to sludge build-up from overcooling, and the elevated EGR soot input leads to accelerated DPF clogging. Cars used mostly in town never get the exhaust hot enough for full passive regeneration. Symptoms include reduced power, warning lights, increased fuel consumption, and limp mode. EGR valve clean or replacement runs €350-900 at a specialist. EGR cooler repair runs around €700-1,000. A blocked DPF can sometimes be cleaned (€300-500), but a full replacement at a Volvo dealer is €2,500-3,500 fitted. Highway use and proper service intervals significantly reduce the risk.

Sensus infotainment freezing and screen failures

€0 - 3,0003 of 6

Tablet-style touchscreen freezes, can fail entirely on early cars · more· less

The portrait-orientation Sensus tablet screen is the car's main interface for almost everything - climate, audio, navigation, even the rear demister. Owners regularly report freezes, black screens, slow boot, and stuck audio. A 30-minute sleep cycle (lock the car, walk away) resolves most temporary freezes. Volvo has issued software updates that fix many issues. In the worst case the entire Sensus head unit needs replacement at €2,000-3,000 - and the resistive touchscreen is known to suffer from delaminated film over time. Try every menu and button during the test drive and ask if the latest software has been installed.

Electrical and Vehicle Connectivity Module (VCM) issues

€200 - 1,2004 of 6

12V battery drains, modules misbehave, VCM software recalls · more· less

What Car? owner data shows 6.8% of S90 owners report electrical faults. Common symptoms include 12V battery drain when parked for more than a few days, intermittent warning lights, and start-stop refusing to operate. The VCM (which sends location to emergency services after a crash) was subject to a recall on cars built between May 2016 and November 2018 - verify this has been completed. Replacement batteries are €250-400 fitted; AGM batteries are specified. Many smaller electrical glitches resolve with software updates.

Air suspension leaks (optional Four-C system)

€1,500 - 4,5005 of 6

Air springs and compressor fail after 80,000-120,000 km on optioned cars · more· less

Only applies to S90s ordered with the optional Four-C air suspension. Air springs are prone to leaks as they age - the car sags overnight, the compressor runs continuously, and warning messages appear. Replacement air springs cost around €1,500-2,000 per corner fitted at a Volvo dealer. The compressor itself runs €600-700 fitted. Independent suspension specialists can offer rebuilt corners for roughly half the dealer price. Most S90 D4s in the European market did not have this option, but verify by checking under the car for the small compressor and reservoir.

Sunroof drain blockage and water ingress

€150 - 1,5006 of 6

Blocked sunroof drains cause water leaks, can damage interior wiring · more· less

The S90's panoramic sunroof drains can clog with debris over time, especially on cars parked under trees. Water then overflows into the headliner, A-pillars, and footwells. In the worst cases this damages the interior wiring harness - some owners report repair bills of €1,000-1,500 for the wiring damage alone. Preventive cleaning of the drains at every service costs nothing. Check footwell carpets and the headliner around the sunroof for damp or staining.

Recall-heavy and below average for the class

The S90 D4 is a comfortable, well-equipped cruiser, but its reliability record is well below BMW 5 Series and Mercedes E-Class. Multiple safety recalls affect 2016-2018 cars, the intake manifold fire recall being the most critical. The D4 engine and Aisin gearbox are fundamentally robust, but the surrounding emissions hardware, Sensus electronics, and optional air suspension are common pain points. Buy a well-maintained, fully recalled example with highway-biased history and avoid heavily optioned air-suspension cars without specialist inspection.

Pre-Purchase Inspection Checklist

General checks

Service history
Complete Volvo dealer or specialist records essential. Service intervals are 12 months or 30,000 km.
Tires
Check tread depth, age (date codes) and uneven wear. 18-19 inch tires are common and expensive.
Cold start
Start engine completely cold. Listen for diesel knock, hesitation, or smoke.
Test drive
Minimum 30 minutes including motorway speed to allow gearbox to warm up and DPF to regenerate.

Specific for this vehicle

Verify intake manifold recall completed
Critical. Cars built before 25 April 2018 are affected. Contact a Volvo dealer with the VIN to confirm the recall work has been done.
Verify all other recalls completed
S90 has 5+ recalls including airbag bolts, seat rails, VCM software, and seatbelts. Get a VIN check from a Volvo dealer.
Sensus screen behaviour
Test every menu, button and submenu. Look for freezes, slow response, or sections that fail to load. Ask for the latest software version.

+ 5 more checksShow less

DPF and EGR signs
Check the service history for forced DPF regenerations or EGR cleaning. Look for limp-mode warnings in the trip computer history.
Check for cold-start hissing (PowerPulse)
Listen for hissing from the engine bay shortly after startup. Indicates a leaking PowerPulse compressor hose.
Air suspension check (if optioned)
Park overnight and check ride height in the morning. Sagging on one corner indicates an air spring leak. Listen for continuous compressor running.
Sunroof drains and headliner
Open the sunroof and inspect the drain channels for debris. Check footwells and headliner for damp or staining.
Inspect for oil leaks at rocker cover and intake manifold
Post-recall, some cars still develop oil weeps at the intake manifold and rocker cover. Light up the engine bay with a torch.

Recalls and Technical Service Bulletins

Intake manifold fire risk (2.0 diesel, built before 25 April 2018) Critical - verify completed

Vehicle Connectivity Module (VCM) software - emergency call location (May 2016 - November 2018) Verify completed

Curtain airbag retaining bolt (November 2016 - April 2017) Verify completed

Airbag inflator specification (August - September 2016) Verify completed

Contact a Volvo dealer with the VIN to verify all recalls have been completed. The intake manifold fire recall is the most important - do not buy a 2016-2018 S90 D4 without confirming this work has been done.

Warranty Status

Factory warranty (2 years) Expired on all used S90 D4s

Volvo Selekt approved-used warranty 12-24 months available when buying from a Volvo dealer

Rust perforation warranty (12 years) Expired on early 2016 cars from 2028 onwards

All S90 D4s are outside their original 2-year factory warranty. Volvo Selekt offers an approved-used warranty on dealer-bought cars. Independent extended warranties are available but check exclusions, especially for EGR, DPF, and Sensus components.
