Volvo V90: common problems and what you need to know

The Volvo V90 combines Scandinavian luxury with practical space and advanced safety technology, but like every modern model it has specific points of attention that owners and potential buyers should keep an eye on. This premium estate offers a lot of value for money, but technical faults in electronics, engine and transmission occur regularly and require targeted attention during maintenance and purchase.

Premium estate with high expectations

The Volvo V90 positions itself as an alternative to German premium estates such as the BMW 5 Series Touring and Mercedes E-Class Estate. With its clean lines, spacious interior and extensive standard equipment, the V90 attracts families and business drivers who want luxury, safety and load space in one package. The model has been available since 2016 and received a facelift in 2020, including the Google Android Automotive infotainment system.

For decades, Volvo has claimed a strong reputation for safety and robustness. The V90 inherited that expectation and does indeed score highly in crash tests. Owners appreciate the comfortable suspension, clear ergonomics and feeling of solidity. Nevertheless, owner experiences and workshop practice show that some components and systems are prone to faults, especially in the first production years.

Why you should know the common problems

Knowing the typical weak points helps you make a well-informed choice. When buying a used example you can specifically check for signs that indicate wear or impending repairs. As an owner, that knowledge sharpens maintenance intervals and prevents small issues from developing into costly failures. Problems with the Volvo models vary by model year and engine type, so detailed information about the V90 saves you time, money and frustration.

In addition, insight into common faults gives you leverage when negotiating. A dealer who openly mentions damage or recent repairs inspires more confidence. A seller who denies all risks actually deserves extra suspicion. The same transparency applies to you as a buyer: ask critical questions and have independent inspections carried out.

Diesel engines and emission systems

Most V90 models on the used market run on diesel, often the 2.0-litre four-cylinder D4 or D5 with turbo. These engines deliver strong torque and are intended for long distances, but the complex emission control requires attention. The diesel particulate filter gets clogged if the car mainly does short city trips, because the exhaust does not get hot enough to burn off soot. Symptoms are loss of power, increased fuel consumption and a warning light on the dashboard.

The EGR system recirculates exhaust gases to reduce nitrogen oxides, but soot build-up can cause the valve to stick. This leads to an irregular idle speed. Poor starting performance also occurs. Some owners report that cleaning or replacing the EGR valve was necessary before 150,000 kilometres. In addition, AdBlue, the urea solution that reduces nitrogen oxides (NOx), depends on sensors and an injection system. Defective AdBlue sensors or clogged lines trigger warnings and, over time, can even lead to a start lock-out.

Practical tips for diesel owners

• Regularly drive a longer distance at a constant speed to regenerate the DPF.
• Have the EGR system inspected every 60,000 kilometres and cleaned if necessary.
• Top up AdBlue in good time and, in the event of a fault, first check the sensors and lines before replacing expensive pumps.

Petrol engines and turbo issues

Petrol variants such as the T5 and T6 use the same 2.0-litre four-cylinder, but with a turbo or turbo plus supercharger. This combination delivers impressive power. However, the turbo wears out due to intensive use or neglected engine oil maintenance. Signs of turbo problems are whistling noises, blue smoke from the exhaust and sudden surges or drops in power.

Direct-injection systems on petrol engines also require clean fuel and regular filter replacement. Contaminated injectors cause rough running, hesitation during acceleration and higher emissions. Some owners report problems with the high-pressure pump. This manifests as starting problems and a sudden engine cut-out.

Maintenance tips for petrol engines

• Change engine oil and filter strictly according to schedule to limit turbo wear.
• Have fuel filters replaced in good time and choose fuel from reliable stations.
• If you notice strange noises or smoke, have the turbo and injection system checked immediately.

Automatic transmission and shift behaviour

Almost all V90 models are equipped with the 8-speed Geartronic automatic gearbox, developed by Aisin. In general this transmission operates smoothly and reliability is good, but some examples show jerks when shifting or refuse to change up smoothly. Aged transmission oil points to this. A defective valve in the hydraulic system can also cause this behaviour.

Owners occasionally report that the gearbox goes into limp mode, where only a single gear remains available. This activates a warning light and requires diagnosis with professional equipment. In most cases, a software update or transmission oil change solves the problem. More serious damage to mechanical components requires an expensive overhaul.

What you can do

• Replace transmission oil every 80,000 kilometres, even if the manufacturer describes it as “maintenance-free”.
• If you experience jerks or hesitation, first have a diagnosis carried out to rule out software updates and oil changes.
• Avoid aggressive shifting with the paddle shifters; in normal conditions, let the automatic gearbox shift by itself.

Electronics and infotainment: modern luxury with teething troubles

The V90 is packed with advanced electronics, from the large vertical touchscreen to dozens of sensors and electronic control units (ECUs). The older Sensus system and the newer Google Android Automotive offer a lot of functionality. However, software bugs and unexpected restarts occur regularly. Owners report frozen screens, unresponsive touch controls and problems with Bluetooth connections.

Sensors for parking assist, blind spot detection and adaptive cruise control are usually reliable, but dirt, damage or electrical faults can cause false alarms or failure. In some cases a sensor must be replaced, but often recalibration or a software update already helps.

How to tackle infotainment problems

• Regularly install available software updates via the settings menu or at the dealer.
• Reset the system by switching the car off completely and waiting 10 minutes before restarting.
• Clean parking sensors and cameras with a soft cloth to prevent false alerts.

Chassis and suspension: comfort versus wear

The V90’s chassis is tuned for comfort and provides a flat, well-damped ride over bumps and on long journeys. The independent suspension with aluminium components contributes to its driving characteristics. However, shock absorbers and control arm bushes wear over time. Symptoms include knocking or rattling noises over uneven surfaces, uneven tyre wear and less precise steering feel.

Some owners report that the air suspension, optionally available on higher trim levels, suffers from leaking air springs or defective compressors. Replacing air springs is expensive, so when buying, check whether the car sits level at all four corners and whether there are any warnings for the air suspension system.

Maintenance tips for the chassis

• Inspect rubbers and bushes annually, especially after 100,000 kilometres or intensive use on poor roads.
• Have shock absorbers replaced if you see signs of leakage or reduced damping comfort.
• With air suspension, regularly check the body height and listen for compressor noise when starting.

Safety systems and driver assistance: when technology fails

Volvo equips the V90 as standard with adaptive cruise control, Pilot Assist, BLIS and automatic emergency braking. These systems significantly increase safety and driving comfort, but depend on cameras, radar and complex software. Dirt on the windscreen where the camera is located temporarily deactivates lane-keeping assist and the emergency braking function. The same applies to the radar sensor behind the Volvo logo in the grille.

Some owners report that Pilot Assist unexpectedly switches off on the motorway or that adaptive cruise control brakes too abruptly. This is caused by software errors, but also by unclear road markings or suddenly changing weather. In practice this means you should always regard these systems as driver aids and not as full autopilot.

Use safety systems wisely

• Keep the windscreen and radar sensor clean, especially in winter conditions and bad weather.
• Recalibrate camera and radar after a windscreen replacement or repairs to the front bumper.
• Do not rely fully on Pilot Assist; stay alert and keep your hands on the steering wheel.

Minor annoyances and preventive maintenance

Besides the bigger technical problems, owners report a number of smaller complaints. The paint finish on aluminium trim strips discolours or flakes over time, especially on models from before 2019. Interior lighting and LED lamps sometimes suffer from contact problems, leading to flickering or failure. In addition, the keyless entry system sometimes does not respond. Replacing the battery in the key usually solves this.

Preventive maintenance remains the best strategy to avoid problems. Follow the manufacturer’s service schedule and add extra checks where necessary, such as inspection of emission systems on diesel engines and software updates for infotainment and driver assistance systems.

Practical tips for daily maintenance

• Check tyre pressure monthly; the V90 has TPMS, but manual checks prevent uneven wear.
• Replace the pollen filter annually to keep climate control and air quality in good condition.
• Clean the key’s contact points and replace batteries to prevent keyless entry problems.

Recognising problems and solving them effectively

Modern cars such as the V90 store fault codes in various electronic control units (ECUs). When a warning light appears or you notice strange behaviour, it is sensible to have the car scanned with professional diagnostic software. Many Volvo specialists and independent workshops have equipment that goes deeper than generic on-board diagnostics (OBD) scanners. That way you can see exactly which component or system needs attention.

Never try to ignore warning signs or delete fault codes without tackling the cause. A fault in the emission system or transmission quickly escalates into engine damage or total failure. If in doubt, it is better to consult a specialist immediately than to keep driving.

Step-by-step plan when faults occur

• Note down symptoms and when they occur so the workshop can carry out targeted diagnosis.
• Have fault codes read and ask for a clear explanation of the cause and possible solutions.
• Compare quotes from several workshops, but choose recognised Volvo specialists for complex electronics and software.

Points to watch when buying a used V90

A thorough pre-purchase inspection saves you from unexpected costs. Check the service history and look for regular servicing at approved workshops. A complete service log with all invoices inspires confidence, whereas missing documentation involves risks. Specifically ask about software updates carried out, sensors that have been replaced and any transmission or engine issues.

Test all electronics during a test drive: infotainment, climate control, seat heating, blind spot monitoring and Pilot Assist. Listen for unusual noises from the chassis, jerks during gear changes and check that all lights operate correctly. Inspect the bodywork for damage to sensors and cameras, and check around the engine bay for leaks or loose wiring.

Checklist for the pre-purchase inspection

• Service history complete and according to schedule, including transmission oil and emission systems.
• No active warning lights on the dashboard; have the fault memory read.
• Test all driver assistance systems and infotainment for correct operation and responsiveness.
• Check chassis and suspension for wear, leaks and damage.
• Ask for a warranty or the option to return the car in case of hidden defects.

Balance between luxury and points of attention

The Volvo V90 offers a convincing package for anyone looking for a premium estate with a focus on safety, comfort and design. Most owners are satisfied with its day-to-day reliability and driving characteristics, but technical faults in electronics, emission systems and transmission occur frequently enough to warrant specific attention. With good preparation, consistent maintenance and realistic expectations, you can enjoy this Scandinavian tourer for many years.

Knowing the common problems enables you to make well-founded choices when it comes to purchase and maintenance. If in doubt, always have an independent inspection carried out and choose specialists who are familiar with the complex electronics and engine management of modern Volvo models. That way you minimise risks and maximise your chances of a worry-free ownership experience.
