Peugeot Ion MOT pass rate & common failures
Across 8 model years and 2,060 tests, the Peugeot Ion passes its MOT 83.2% of the time. Against all cars of a similar age (20.4% fail rate), the Ion comes out 3.6pp better. Its most common failure areas are tyres, brakes and suspension.
What the MOT record shows
No single area dominates — tyres (5.4%) and brakes (5.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are track rod end, rigid brake pipes and tread depth — track rod end alone was recorded 89 times.
Condition tracks the odometer closely. Failures run at 12.4% in the 0-30k band and 26.7% in the 90-120k band, a 14.3-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 24.5% of tests without failing them.
The trend is worsening — 12.8% of tests failed in 2021 against 20.5% 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 | Tyres | 24.5% | 504 |
| 2 | Brakes | 23.4% | 483 |
| 3 | Suspension | 23.2% | 477 |
| 4 | Steering | 8.9% | 184 |
| 5 | Other defects | 3.9% | 80 |
| 6 | Body, structure & corrosion | 3.3% | 67 |
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 | 720 | 12.4% |
| 30-60k | 1,018 | 16.7% |
| 60-90k | 286 | 26.9% |
| 90-120k | 30 | 26.7% |
Failure rate by age

What to check before buying a Peugeot Ion
- Tyres (5.4% 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 (5.1% 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.
- Suspension (4.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
