6 Most Common Volvo S90 Problems

These are the faults most frequently seen on the Volvo S90 by UK garages — ranked by how commonly they occur and what they cost to fix.

1
DPF Blockage (D4/D5 Diesel)
High Priority
Diesel S90s — typically company fleet cars driven on urban routes — develop DPF blockages. A large premium saloon used on short commuter runs is a high DPF risk.
💷 Typical repair cost: £150–£1,800
2
AdBlue System Faults (D4/D5)
High Priority
The S90 diesel requires AdBlue. Running low, injector faults or sensor issues prevent restarting after a threshold is crossed. Common on high-mileage fleet examples.
💷 Typical repair cost: £10–£800
3
T8 PHEV Battery Degradation
Watch
The T8 Recharge PHEV battery degrades over time — EV range reduces on older examples. Always test actual EV range before buying a used T8 S90.
💷 Typical repair cost: £2,000–£6,000
4
Pilot Assist / ADAS Sensor Faults
Watch
Pilot Assist lane keeping, adaptive cruise and autobrake sensor faults are reported on some S90s — usually requiring recalibration after windscreen replacement or accident repairs.
💷 Typical repair cost: £100–£600
5
Automatic Gearbox Hesitation (Early Aisin)
Watch
Some early S90 examples reported gearbox hesitation and judder from the Aisin 8-speed — addressed by software updates.
💷 Typical repair cost: £0–£1,500
6
Rear Air Suspension (Optional)
Low Priority
S90 models with optional rear air suspension can develop compressor and height sensor faults on higher-mileage examples.
💷 Typical repair cost: £300–£1,500
