2001 Jaguar S-Type — MOT failures & pass rate
The 2001 Jaguar S-Type passed 70.4% of its 5,720 recorded MOT tests. Executive cars of a similar age fail 24.1% of the time, so this is 5.5pp worse than the group it competes with. Failures cluster in suspension, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (17.6%) and brakes (14.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are ball joint dust cover, track rod end and rigid brake pipes — ball joint dust cover alone was recorded 863 times.
Mileage is the strongest signal on the record: 19.8% of 0-30k cars fail, rising to 30.5% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 40.6% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 40.6% | 2,320 |
| 2 | Suspension | 40.0% | 2,287 |
| 3 | Tyres | 24.5% | 1,400 |
| 4 | Steering | 11.9% | 680 |
| 5 | Lighting & signalling | 8.9% | 512 |
| 6 | Other defects | 8.1% | 464 |
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 | 121 | 19.8% |
| 30-60k | 903 | 25.6% |
| 60-90k | 1,698 | 29.0% |
| 90-120k | 1,636 | 30.4% |
| 120-150k | 894 | 33.8% |
| 150k+ | 436 | 30.5% |

What to check before buying a 2001 S-Type
On a 2001 S-Type, suspension is what the MOT record says goes wrong most — it appeared in 17.6% of tests. Check these areas before you commit.
- Suspension (17.6% 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 (14.7% 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.
- Lighting & signalling (9.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
