2013 Hyundai I800 — MOT failures & pass rate
1,337 MOT tests on the 2013 Hyundai I800 are in this dataset, and 76.4% of them passed. Against all cars of a similar age (20.1% fail rate), the 2013 I800 comes out 3.6pp worse. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (14.9%) 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 rbt (sp), position lamp and service brake performance — rbt (sp) alone was recorded 86 times.
Condition tracks the odometer closely. Failures run at 7.9% in the 0-30k band and 24.2% in the 150k+ band, a 16.3-point spread — more than double.
Advisories point at the next bill rather than this one: brakes was flagged on 33.6% of tests without failing them.
The trend is worsening — 19.8% of tests failed in 2021 against 25.2% 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 | 33.6% | 449 |
| 2 | Tyres | 20.0% | 267 |

| 5 | Other defects | 10.4% | 139 |
| 6 | Emissions & environmental | 6.0% | 80 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

What to check before buying a 2013 I800
On a 2013 I800, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.9% of tests. Check these areas before you commit.
- Lighting & signalling (14.9% 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 (4.6% 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.
