1996 Jaguar XJ — MOT failures & pass rate
Across 4,128 MOT tests, the 1996 Jaguar XJ recorded an 80.2% pass rate. Executive cars of a similar age fail 21.7% of the time, so this is 1.9pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (8.3%) and suspension (8.2%) 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 component mounting prescribed areas — catalyst emissions alone was recorded 372 times.
A 150k+ example is materially riskier than a 0-30k one: 25.5% versus 7.8%.
Advisories point at the next bill rather than this one: suspension was flagged on 41.3% of tests without failing them.
The trend is improving — the fail rate fell from 21.1% in 2021 to 17.0% in 2025, as the worst-kept examples leave the fleet.

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 | 41.3% | 1,706 |
| 2 | Brakes | 20.7% | 854 |
| 3 | Tyres | 18.0% | 742 |
| 4 | Body, structure & corrosion | 14.8% | 612 |
| 5 | Emissions & environmental | 14.3% | 590 |
| 6 | Other defects | 10.4% | 428 |
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 | 103 | 7.8% |
| 30-60k | 458 | 11.3% |
| 60-90k | 974 | 16.6% |
| 90-120k | 1,252 | 20.6% |
| 120-150k | 839 | 25.1% |
| 150k+ | 487 | 25.5% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 1,064 | 21.1% |
| 2022 | 949 | 20.4% |
| 2023 | 806 | 20.2% |

What to check before buying a 1996 XJ
On a 1996 XJ, lighting & signalling is what the MOT record says goes wrong most — it appeared in 8.3% of tests. Check these areas before you commit.
- Lighting & signalling (8.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (8.2% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- 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.
