Should I check the MOT history before buying a 2018 Kia Sportage?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2018 Kia Sportage passes its MOT first time at 88.2%, well above the UK average of 80%, which is genuinely solid. However, 28.3% of these vehicles have recorded a dangerous defect at some point, which is notably high and worth taking seriously during your pre-purchase inspection.

At an average mileage of 40,383 miles, these cars are running light for their age, suggesting relatively gentle use across the fleet. The 0.79 average failures per vehicle is low, but the 6.1 advisories indicate minor wear is accumulating—check brakes, suspension and lighting carefully on any example you're considering.

The 2018 Kia Sportage has a decent first-time pass rate (88.2%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 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 88.2% 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 6.1 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 33,707 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.
