2018 Jaguar I-Pace — MOT failures & pass rate
The 2018 Jaguar I-Pace passed 91.7% of its 4,111 recorded MOT tests. Mid-size SUVs of a similar age fail 10.2% of the time, so this is 1.9pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and steering.
What the MOT record shows
One area stands out: tyres, recorded in 5.0% of tests against 1.8% for the next-worst category.
At component level the recurring items are track rod end, headlamp aim and registration plates — track rod end alone was recorded 82 times.
Condition tracks the odometer closely. Failures run at 7.0% in the 0-30k band and 17.8% in the 90-120k band, a 10.8-point spread — more than double.
Tyres is the most common advisory, noted on 16.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 7.1% of tests failed in 2021 against 10.2% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

| 5 | Suspension | 1.1% | 46 |
| 6 | Visibility | 1.0% | 40 |
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 | 2,117 | 7.0% |
| 30-60k | 1,601 | 8.7% |
| 60-90k | 342 | 13.2% |
| 90-120k | 45 | 17.8% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2018 I-Pace
The failure pattern for this year is specific enough to inspect against: tyres accounted for 5.0% of tests. Start there.
- Tyres (5.0% 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.
- Lighting & signalling (1.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Steering (1.6% of tests): Play, leaks or worn track rod ends — affects handling and is a safety item. Typical repair: £150–£500.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
