2016 Hyundai I800 — MOT failures & pass rate
6,609 MOT tests on the 2016 Hyundai I800 are in this dataset, and 78.2% of them passed. That is 7.2 percentage points worse than all cars of a similar age, which fail at 14.5%. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 19.2% of tests against 13.0% for the next-worst category.
At component level the recurring items are headlamp aim, position lamp and rbt (sp) — headlamp aim alone was recorded 670 times.
A 150k+ example is materially riskier than a 0-30k one: 19.9% versus 15.4%.
Brakes is the most common advisory, noted on 24.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 20.0% of tests failed in 2021 against 23.7% 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 | 24.8% | 1,642 |
| 2 | Tyres | 22.3% | 1,471 |

| 5 | Suspension | 4.3% | 285 |
| 6 | Visibility | 3.5% | 233 |
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 | 247 | 15.4% |
| 30-60k | 2,117 | 20.4% |

What to check before buying a 2016 I800
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 19.2% of tests. Start there.
- Lighting & signalling (19.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (13.0% 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 (5.4% 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.
