2011 Peugeot Ion — MOT failures & pass rate
Across 458 MOT tests, the 2011 Peugeot Ion recorded an 83.4% pass rate. That is 6.5 percentage points better than all cars of a similar age, which fail at 23.1%. Failures cluster in tyres, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (6.3%) and brakes (5.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rigid brake pipes, track rod end and tread depth — rigid brake pipes alone was recorded 18 times.
A 60-90k example is materially riskier than a 0-30k one: 26.8% versus 10.9%.
Advisories point at the next bill rather than this one: brakes was flagged on 30.3% of tests without failing them.
The trend is worsening — 10.3% of tests failed in 2021 against 15.0% 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 |
|---|---|---|---|
| 1 | Brakes | 30.3% | 139 |
| 2 | Tyres | 27.7% | 127 |
| 3 | Suspension | 22.9% | 105 |
| 4 | Steering | 8.9% | 41 |
| 5 | Other defects | 3.3% | 15 |
| 6 | Lighting & signalling | 3.1% | 14 |
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 | 110 | 10.9% |
| 30-60k | 267 | 15.7% |
| 60-90k | 71 | 26.8% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2022 | 101 | 20.8% |
| 2023 | 95 | 20.0% |

What to check before buying a 2011 Ion
On a 2011 Ion, tyres is what the MOT record says goes wrong most — it appeared in 6.3% of tests. Check these areas before you commit.
- Tyres (6.3% 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.
- Brakes (5.0% 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 (3.9% 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.
