Should I check the MOT history before buying a 2018 Hyundai I800?

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.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2018 Hyundai i800 sits slightly below the UK average with a 77.5% first-time pass rate, but the real concern is that 30.1% of vehicles have recorded a dangerous defect at some point—well above what you'd expect. This suggests systemic safety issues that buyers should take seriously when inspecting a used example.

At 60,209 miles on average, these vehicles are showing typical mileage for their age, yet they're averaging 1.77 failures per MOT, indicating wear-related problems are materialising faster than comparable models. Before buying, get a pre-purchase inspection that specifically covers brake systems, suspension, and steering components—the dangerous defect rate points to these as weak spots on this generation.

The 2018 Hyundai I800 has a decent first-time pass rate (77.5%), 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

🔧 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 7.5 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 1,144 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.
