Moderate sample. 305 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

This Volvo V90 B4 MHEV is reliably passing its MOTs at 91.1%, comfortably above the UK average of 80%, with the diesel hybrid variant performing marginally better at 92.2% than the petrol hybrid at 90.2%. The dangerous defect rate sits at 10.8%, which is manageable but worth noting during your pre-purchase inspection.

With a median mileage of 31,827 miles for a 2021, these are relatively low-mileage cars, and the average failure count of just 0.25 per vehicle confirms they're holding up well mechanically. Most issues that do emerge are minor advisories (1.8 per vehicle on average), so focus your buying checklist on routine maintenance history rather than structural concerns—and always request full service records to confirm the hybrid system has been properly maintained.

The 2021 Volvo V90 Momentum B4 MHEV Auto passes its MOT first time more often than most UK vehicles (92.3% vs ~80% average) — and when it does fail, it's usually something minor and cheap to fix.

⚠️ About 1 in 12 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
✅ Good baseline reliability. A 92.3% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.
🔧 Expect consumable spend. An average of 1.8 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 305 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
