2012 Peugeot Horizon — MOT failures & pass rate
The 2012 Peugeot Horizon passed 77.5% of its 1,629 recorded MOT tests. All cars of a similar age fail at 21.7%, so the 2012 Horizon sits squarely on the average. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 13.9% of all tests — 3.4 points clear of suspension, so it is the first thing to check.
At component level the recurring items are joints, coil spring and stop lamp — joints alone was recorded 112 times.
Mileage is the strongest signal on the record: 12.9% of 0-30k cars fail, rising to 25.8% once past 150k.
Advisories point at the next bill rather than this one: tyres was flagged on 19.1% of tests without failing them.
The trend is worsening — 20.3% of tests failed in 2021 against 25.3% 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 | 19.1% | 311 |
| 2 | Brakes | 16.8% | 274 |
| 3 | Suspension | 16.2% | 264 |

| 5 | Body, structure & corrosion | 9.8% | 159 |
| 6 | Other defects | 5.4% | 88 |
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 | 209 | 12.9% |
| 30-60k | 521 | 22.3% |

| 90-120k | 215 | 27.4% |
| 120-150k | 136 | 22.8% |
| 150k+ | 279 | 25.8% |

What to check before buying a 2012 Horizon
On a 2012 Horizon, lighting & signalling is what the MOT record says goes wrong most — it appeared in 13.9% of tests. Check these areas before you commit.
- Lighting & signalling (13.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.4% 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.
- Body, structure & corrosion (9.2% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
