2009 Hyundai I800 — MOT failures & pass rate
1,192 MOT tests on the 2009 Hyundai I800 are in this dataset, and 70.3% of them passed. All cars of a similar age fail 25.4% of the time, so this is 4.3pp worse than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (19.0%) and brakes (17.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, rbt (sp) and position lamp — headlamp aim alone was recorded 114 times.
Mileage is the strongest signal on the record: 18.0% of 30-60k cars fail, rising to 32.8% once past 150k.
Brakes is the most common advisory, noted on 36.7% of tests — work that passed today but is likely due soon.
The trend is worsening — 28.3% of tests failed in 2021 against 32.2% 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 | 36.7% | 438 |
| 2 | Suspension | 30.5% | 364 |
| 3 | Lighting & signalling | 28.4% | 338 |
| 4 | Other defects | 25.1% | 299 |
| 5 | Tyres | 22.7% | 271 |
| 6 | Emissions & environmental | 14.3% | 171 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 50 | 18.0% |
| 60-90k | 246 | 24.8% |
| 90-120k | 433 | 32.6% |
| 120-150k | 274 | 29.6% |
| 150k+ | 186 | 32.8% |
Failure rate by age
Trend over time

What to check before buying a 2009 I800
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 19.0% of tests. Start there.
- Lighting & signalling (19.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (17.3% 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.
- Suspension (14.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
