1996 Jaguar Xjs — MOT failures & pass rate
The 1996 Jaguar Xjs passed 84.1% of its 1,118 recorded MOT tests. That is 8.7 percentage points better than all cars of a similar age, which fail at 24.6%. Failures cluster in lighting & signalling, brakes and emissions & environmental.
What the MOT record shows
No single area dominates — lighting & signalling (6.2%) and brakes (5.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, headlamp and component mounting prescribed areas — catalyst emissions alone was recorded 94 times.
Condition tracks the odometer closely. Failures run at 8.9% in the 0-30k band and 25.7% in the 150k+ band, a 16.8-point spread — more than double.
Suspension is the most common advisory, noted on 21.6% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 17.9% in 2021 to 15.9% 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 | 21.6% | 241 |
| 2 | Brakes | 12.5% | 140 |
| 3 | Tyres | 10.6% | 119 |
| 4 | Emissions & environmental | 10.2% | 114 |
| 5 | Body, structure & corrosion | 5.5% | 62 |
| 6 | Other defects | 3.3% | 37 |
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 | 79 | 8.9% |
| 30-60k | 206 | 9.7% |
| 60-90k | 361 | 17.2% |
| 90-120k | 274 | 15.3% |
| 120-150k | 128 | 22.7% |
| 150k+ | 70 | 25.7% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1996 Xjs
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.2% of tests. Start there.
- Lighting & signalling (6.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (5.5% 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.
- Emissions & environmental (4.8% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
