2014 Nissan Skyline — MOT failures & pass rate
Across 295 MOT tests, the 2014 Nissan Skyline recorded an 88.8% pass rate. Against all cars of a similar age (17.9% fail rate), the 2014 Skyline comes out 6.7pp better. Failures cluster in lighting & signalling, emissions & environmental and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (6.4%) and emissions & environmental (5.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, headlamp aim and rear fog lamp — catalyst emissions alone was recorded 17 times.
Mileage matters less than usual here: the 2014 Skyline fails 5.6% of the time in the 30-60k band and 5.1% at 120-150k, a spread of only 0.4 points.
Suspension is the most common advisory, noted on 13.9% of tests — work that passed today but is likely due soon.
The trend is worsening — 10.1% of tests failed in 2021 against 14.9% 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 | Suspension | 13.9% | 41 |
| 2 | Tyres | 10.8% | 32 |
| 3 | Brakes | 9.2% | 27 |

| 5 | Steering | 4.8% | 14 |
| 6 | Emissions & environmental | 4.4% | 13 |
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 | 54 | 5.6% |
| 60-90k | 71 | 11.3% |
| 90-120k | 99 | 14.1% |
| 120-150k | 39 | 5.1% |
Failure rate by age

What to check before buying a 2014 Skyline
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.4% of tests. Start there.
- Lighting & signalling (6.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (5.4% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Body, structure & corrosion (2.4% 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.
