2018 Suzuki Ignis — MOT failures & pass rate
Across 32,180 MOT tests, the 2018 Suzuki Ignis recorded a 91.2% pass rate. That is effectively the same as city cars of a similar age (9.7% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in visibility, suspension and tyres.
What the MOT record shows
No single area dominates — visibility (4.3%) and suspension (4.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, coil spring and tread depth — wipers alone was recorded 1,516 times.
Mileage is the strongest signal on the record: 6.5% of 0-30k cars fail, rising to 19.4% once past 90-120k — 3.0× the risk.
Fuel type barely separates them — petrol fails 8.6% of the time against 9.5% for hybrid.
Tyres is the most common advisory, noted on 22.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 4.1% of tests failed in 2021 against 12.9% 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.

| 6 | Steering | 0.8% | 265 |
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 | 21,070 | 6.5% |
| 30-60k | 9,615 | 12.5% |

What to check before buying a 2018 Ignis
The failure pattern for this year is specific enough to inspect against: visibility accounted for 4.3% of tests. Start there.
- Visibility (4.3% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Suspension (4.3% 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.
- Tyres (2.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
