2017 Jaguar Xjr — MOT failures & pass rate
The 2017 Jaguar Xjr passed 92.4% of its 291 recorded MOT tests. Against all cars of a similar age (12.5% fail rate), the 2017 Xjr comes out 5.0pp better. Failures cluster in tyres, suspension and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.5%) and suspension (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tyre pressure monitoring system and malfunction indicator lamp — headlamp aim alone was recorded 5 times.
Condition tracks the odometer closely. Failures run at 2.5% in the 0-30k band and 12.3% in the 60-90k band, a 9.8-point spread — more than double.
Tyres is the most common advisory, noted on 17.9% of tests — work that passed today but is likely due soon.
The trend is worsening — 8.7% of tests failed in 2021 against 12.7% in 2025, the usual pattern as a fleet ages.

| 0-30k | 79 | 2.5% |
| 30-60k | 133 | 7.5% |
| 60-90k | 57 | 12.3% |

What to check before buying a 2017 Xjr
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.5% of tests. Start there.
- Tyres (4.5% 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.
- Suspension (2.1% 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.
- Lighting & signalling (1.7% 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.
