Hyundai I800 (2018)
2018 Hyundai I800
CarHunch analysed 1,144 real MOT records for the 2018 Hyundai I800. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
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.
What to check before buying a 2018 Hyundai I800
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 30.1% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
