The 2018 Subaru Outback is significantly more reliable than average, with a 91.4% first-time pass rate well above the UK average of 80%, and both petrol and diesel variants perform equally well at around 91%. The dangerous defect rate of 15.4% is moderate and shouldn't deter most buyers, though it's worth checking brake and suspension components during a pre-purchase inspection.

These vehicles are running at sensible mileage for their age (median 40,037 miles), suggesting owners treat them reasonably well, and the low average failure count of 0.55 per vehicle confirms they're mechanically sound. Focus your pre-buy check on the 4.7 advisory items commonly flagged—typically minor wear items like wiper blades and fluid levels—which are easily resolved and won't impact ownership costs significantly.

The 2018 Subaru Outback passes its MOT first time at roughly the UK average rate (91.4%) — solid but worth checking this vehicle's history carefully.

⚠️ Around 1 in 8 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 91.4% 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 4.7 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 655 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.
