2011 Hyundai I800 — MOT failures & pass rate
The 2011 Hyundai I800 passed 72.8% of its 3,608 recorded MOT tests. Against all cars of a similar age (23.0% fail rate), the 2011 I800 comes out 4.1pp worse. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (16.4%) and lighting & signalling (15.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), service brake performance and position lamp — rbt (sp) alone was recorded 252 times.
Mileage is the strongest signal on the record: 21.2% of 0-30k cars fail, rising to 27.1% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 36.6% of tests without failing them.

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 | 36.6% | 1,319 |
| 2 | Tyres | 23.8% | 859 |
| 3 | Suspension | 23.2% | 837 |

| 5 | Other defects | 15.0% | 543 |
| 6 | Emissions & environmental | 13.2% | 476 |
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 | 33 | 21.2% |
| 30-60k | 322 | 21.1% |
| 60-90k | 998 | 25.4% |
| 90-120k | 1,294 | 29.1% |
| 120-150k | 607 | 29.3% |
| 150k+ | 354 | 27.1% |

What to check before buying a 2011 I800
On a 2011 I800, brakes is what the MOT record says goes wrong most — it appeared in 16.4% of tests. Check these areas before you commit.
- Brakes (16.4% 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.
- Lighting & signalling (15.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.4% 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.
