2019 Renault Koleos — MOT failures & pass rate
3,530 MOT tests on the 2019 Renault Koleos are in this dataset, and 88.9% of them passed. That is effectively the same as all cars of a similar age (10.1% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in brakes, tyres and emissions & environmental.
What the MOT record shows
No single area dominates — brakes (4.6%) and tyres (3.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake pads, malfunction indicator lamp and wipers — brake pads alone was recorded 190 times.
Mileage is the strongest signal on the record: 6.9% of 0-30k cars fail, rising to 18.6% once past 90-120k — 2.7× the risk.
Brakes is the most common advisory, noted on 22.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 2.2% of tests failed in 2021 against 13.4% 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 | 22.4% | 791 |
| 2 | Tyres | 21.9% | 773 |

| 5 | Visibility | 3.3% | 115 |
| 6 | Emissions & environmental | 0.7% | 24 |
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 | 1,285 | 6.9% |
| 30-60k | 1,798 | 12.8% |
| 60-90k | 398 | 16.3% |
| 90-120k | 43 | 18.6% |
Failure rate by age
Trend over time

What to check before buying a 2019 Koleos
The failure pattern for this year is specific enough to inspect against: brakes accounted for 4.6% of tests. Start there.
- Brakes (4.6% 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 (3.6% 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.
- Emissions & environmental (3.3% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
