2001 Jaguar Xjr — MOT failures & pass rate
Across 830 MOT tests, the 2001 Jaguar Xjr recorded a 79.6% pass rate. That is 6.7 percentage points better than all cars of a similar age, which fail at 27.0%. Failures cluster in suspension, brakes and emissions & environmental.
What the MOT record shows
No single area dominates — suspension (8.7%) and brakes (7.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, catalyst emissions and integral vehicle structure condition — component mounting prescribed areas alone was recorded 73 times.
A 150k+ example is materially riskier than a 30-60k one: 26.4% versus 10.3%.
Advisories point at the next bill rather than this one: suspension was flagged on 28.8% of tests without failing them.
The trend is improving — the fail rate fell from 23.3% in 2021 to 19.4% 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 | 28.8% | 239 |
| 2 | Brakes | 22.2% | 184 |
| 3 | Body, structure & corrosion | 15.3% | 127 |
| 4 | Tyres | 15.3% | 127 |
| 5 | Other defects | 7.7% | 64 |
| 6 | Emissions & environmental | 7.7% | 64 |
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 | 87 | 10.3% |
| 60-90k | 176 | 15.3% |
| 90-120k | 230 | 21.7% |
| 120-150k | 219 | 24.7% |
| 150k+ | 106 | 26.4% |

What to check before buying a 2001 Xjr
On a 2001 Xjr, suspension is what the MOT record says goes wrong most — it appeared in 8.7% of tests. Check these areas before you commit.
- Suspension (8.7% 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.
- Brakes (7.5% 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 (7.5% 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.
