2014 Nissan Nv400 — MOT failures & pass rate
Across 352 MOT tests, the 2014 Nissan Nv400 recorded a 74.2% pass rate. That is 2.7 percentage points worse than vans of a similar age, which fail at 23.2%. Failures cluster in brakes, lighting & signalling and body, structure & corrosion.
What the MOT record shows
No single area dominates — brakes (15.6%) and lighting & signalling (13.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rigid brake pipes, rbt (sp) and headlamp aim — rigid brake pipes alone was recorded 29 times.
Condition tracks the odometer closely. Failures run at 20.8% in the 30-60k band and 32.0% in the 150k+ band, a 11.2-point spread.
Advisories point at the next bill rather than this one: brakes was flagged on 39.2% of tests without failing them.
The trend is worsening — 22.9% of tests failed in 2021 against 26.9% 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 | 39.2% | 138 |
| 2 | Tyres | 20.2% | 71 |
| 3 | Lighting & signalling | 15.3% | 54 |
| 4 | Suspension | 13.9% | 49 |
| 5 | Visibility | 9.1% | 32 |
| 6 | Other defects | 5.7% | 20 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 48 | 20.8% |
| 60-90k | 58 | 20.7% |
| 90-120k | 73 | 23.3% |
| 120-150k | 54 | 35.2% |
| 150k+ | 103 | 32.0% |
Failure rate by age

What to check before buying a 2014 Nv400
On a 2014 Nv400, brakes is what the MOT record says goes wrong most — it appeared in 15.6% of tests. Check these areas before you commit.
- Brakes (15.6% 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.
- Lighting & signalling (13.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (6.3% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
