2014 Nissan 370 Z — MOT failures & pass rate
The 2014 Nissan 370 Z passed 89.0% of its 417 recorded MOT tests. Against all cars of a similar age (18.6% fail rate), the 2014 370 Z comes out 7.6pp better. Failures cluster in emissions & environmental, tyres and brakes.
What the MOT record shows
No single area dominates — emissions & environmental (4.3%) and tyres (4.3%) 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 26 times.
Condition tracks the odometer closely. Failures run at 9.4% in the 0-30k band and 18.9% in the 60-90k band, a 9.5-point spread — more than double.
Tyres is the most common advisory, noted on 19.2% of tests — work that passed today but is likely due soon.

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 | 19.2% | 80 |
| 2 | Suspension | 8.2% | 34 |
| 3 | Brakes | 7.2% | 30 |

| 5 | Other defects | 1.9% | 8 |
| 6 | Steering | 1.9% | 8 |
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 | 117 | 9.4% |
| 30-60k | 217 | 9.2% |
| 60-90k | 74 | 18.9% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 71 | 9.9% |
| 2022 | 74 | 5.4% |
| 2023 | 83 | 14.5% |

What to check before buying a 2014 370 Z
The failure pattern for this year is specific enough to inspect against: emissions & environmental accounted for 4.3% of tests. Start there.
- Emissions & environmental (4.3% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Tyres (4.3% 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 (2.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
