2017 Ford Allied — MOT failures & pass rate
Across 2,511 MOT tests, the 2017 Ford Allied recorded an 82.0% pass rate. That is 5.2 percentage points worse than all cars of a similar age, which fail at 12.8%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (6.7%) and suspension (6.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are pins and bushes, linkage pins and bushes and joints — pins and bushes alone was recorded 94 times.
A 150k+ example is materially riskier than a 0-30k one: 25.3% versus 9.1%.
Brakes is the most common advisory, noted on 21.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 13.9% of tests failed in 2021 against 20.3% 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 |

| 5 | Lighting & signalling | 5.7% | 142 |
| 6 | Visibility | 5.5% | 138 |
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 | 604 | 9.1% |
| 30-60k | 847 | 17.9% |
| 60-90k | 388 | 21.9% |
| 90-120k | 176 | 21.6% |
| 120-150k | 159 | 23.3% |
| 150k+ | 336 | 25.3% |

What to check before buying a 2017 Allied
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.7% of tests. Start there.
- Lighting & signalling (6.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (6.3% 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.
- Brakes (4.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
