2015 Jaguar XF — MOT failures & pass rate
57,733 MOT tests on the 2015 Jaguar XF are in this dataset, and 85.1% of them passed. That is effectively the same as executive cars of a similar age (14.1% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (7.6%) and lighting & signalling (6.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are registration plate lamp(s), tread depth and brake pads — registration plate lamp(s) alone was recorded 3,107 times.
A 150k+ example is materially riskier than a 0-30k one: 21.8% versus 8.0%.
The petrol cars hold up better: 10.1% fail against 14.9% for diesel, a 4.9-point gap across 57,733 tests.
Tyres is the most common advisory, noted on 25.7% of tests — work that passed today but is likely due soon.
The trend is worsening — 13.0% of tests failed in 2021 against 16.6% 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.

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 | 3,117 | 8.0% |
| 30-60k | 19,324 | 12.0% |
| 60-90k | 20,759 | 15.8% |
| 90-120k | 10,025 | 18.1% |
| 120-150k | 3,250 | 19.9% |
| 150k+ | 1,246 | 21.8% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |

What to check before buying a 2015 XF
The failure pattern for this year is specific enough to inspect against: tyres accounted for 7.6% of tests. Start there.
- Tyres (7.6% 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.
- Lighting & signalling (6.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (3.8% 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.
