The 2018 Kia Sorento passes its MOT first time in 88.7% of cases, well ahead of the UK average of 80%, which is a genuinely strong result—though the concerning note is that 22.4% of these vehicles have recorded a dangerous defect at some point, above the typical threshold for buyer caution. This diesel-only cohort is holding up mechanically, suggesting good engineering durability for the model year.

At 42,000 miles median for a six-year-old vehicle, these Sorentos are running with typical mileage and show an average of 0.76 failures per test, indicating minor issues when they do crop up. The 6.0 advisories per vehicle suggests routine wear is being flagged regularly, so budget for preventative maintenance—if you're considering one, get a full pre-purchase inspection and specifically ask the seller about any history of suspension, brake, or emissions work, given the dangerous defect rate.

The 2018 Kia Sorento passes its MOT first time at roughly the UK average rate (88.7%) — solid but worth checking this vehicle's history carefully.

For context

✅ Good baseline reliability. A 88.7% 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 6 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 2,748 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.
