2015 Nissan 370 Z — MOT failures & pass rate
Across 428 MOT tests, the 2015 Nissan 370 Z recorded a 91.4% pass rate. Against all cars of a similar age (16.9% fail rate), the 2015 370 Z comes out 8.2pp better. Failures cluster in emissions & environmental, tyres and brakes.
What the MOT record shows
No single area dominates — emissions & environmental (3.5%) and tyres (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, tread depth and wipers — catalyst emissions alone was recorded 21 times.
A 60-90k example is materially riskier than a 0-30k one: 14.1% versus 3.6%.
Advisories point at the next bill rather than this one: tyres was flagged on 18.5% of tests without failing them.
The trend is worsening — 6.8% of tests failed in 2021 against 8.8% 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 |
|---|---|---|---|
| 1 | Tyres | 18.5% | 79 |
| 2 | Brakes | 8.4% | 36 |
| 3 | Visibility | 5.4% | 23 |
| 4 | Suspension | 5.1% | 22 |
| 5 | Other defects | 3.5% | 15 |
| 6 | Body, structure & corrosion | 1.6% | 7 |
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 | 110 | 3.6% |
| 30-60k | 234 | 9.0% |
| 60-90k | 78 | 14.1% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 59 | 6.8% |
| 2022 | 88 | 12.5% |
| 2023 | 86 | 9.3% |

What to check before buying a 2015 370 Z
On a 2015 370 Z, emissions & environmental is what the MOT record says goes wrong most — it appeared in 3.5% of tests. Check these areas before you commit.
- Emissions & environmental (3.5% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Tyres (2.1% 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.
- Brakes (1.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
