Moderate sample. 469 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2021 Citroën Relay 35 L3 X BlueHDi is marginally less reliable than the UK average, with a 78.9% first-time pass rate compared to 80% nationally—a minor difference, but worth noting. The 10.4% rate of dangerous defects is well below the concerning threshold, so safety issues aren't a red flag for this cohort.

At roughly 58,500 miles, these vans are running at typical mileage for their age, and the 0.58 average failures per vehicle suggests most are holding up reasonably well. The 1.7 advisories per vehicle indicate minor wear accumulating (worn brake pads, light corrosion), so budget for routine maintenance—and when shopping, ask the seller for full service history to confirm the engine and gearbox have been properly looked after.

The 2021 Citroen Relay 35 L3 X Bluehdi S/s passes its MOT first time at roughly the UK average rate (81.3%) — solid but worth checking this vehicle's history carefully.

⚠️ 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
🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.
🔧 Expect consumable spend. An average of 1.7 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 469 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.
