2014 Hyundai I800 — MOT failures & pass rate
The 2014 Hyundai I800 passed 76.5% of its 971 recorded MOT tests. Against all cars of a similar age (18.3% fail rate), the 2014 I800 comes out 5.2pp worse. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (17.1%) and brakes (14.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are position lamp, headlamp aim and rbt (sp) — position lamp alone was recorded 78 times.
A 150k+ example is materially riskier than a 0-30k one: 30.7% versus 11.8%.
Brakes is the most common advisory, noted on 28.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 23.1% of tests failed in 2021 against 26.3% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 28.6% | 278 |
| 2 | Tyres | 22.9% | 222 |
| 3 | Lighting & signalling | 15.2% | 148 |
| 4 | Suspension | 11.2% | 109 |
| 5 | Other defects | 8.3% | 81 |
| 6 | Seat belts & restraints | 5.3% | 51 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 34 | 11.8% |
| 30-60k | 161 | 15.5% |
| 60-90k | 324 | 21.9% |
| 90-120k | 214 | 25.7% |
| 120-150k | 137 | 30.7% |
| 150k+ | 101 | 30.7% |

What to check before buying a 2014 I800
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 17.1% of tests. Start there.
- Lighting & signalling (17.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (14.4% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Tyres (5.6% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
