2018 Hyundai i10 — MOT failures & pass rate
The 2018 Hyundai i10 passed 90.5% of its 116,480 recorded MOT tests. City cars of a similar age fail at 9.8%, so the 2018 i10 sits squarely on the average. Failures cluster in lighting & signalling, visibility and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (5.5%) and visibility (4.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are daytime running lamps, wipers and brake pads — daytime running lamps alone was recorded 4,217 times.
Condition tracks the odometer closely. Failures run at 6.8% in the 0-30k band and 18.8% in the 150k+ band, a 12.0-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 18.6% of tests without failing them.
The trend is worsening — 5.7% of tests failed in 2021 against 12.8% 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 |

| 6 | Suspension | 0.7% | 761 |
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 | 74,187 | 6.8% |
| 30-60k | 36,651 | 13.6% |

What to check before buying a 2018 i10
On a 2018 i10, lighting & signalling is what the MOT record says goes wrong most — it appeared in 5.5% of tests. Check these areas before you commit.
- Lighting & signalling (5.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (4.2% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Tyres (3.1% 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.
