2020 Ford Allied — MOT failures & pass rate
3,246 MOT tests on the 2020 Ford Allied are in this dataset, and 87.6% of them passed. That is 3.0 percentage points worse than all cars of a similar age, which fail at 9.4%. Failures cluster in visibility, tyres and lighting & signalling.
What the MOT record shows
No single area dominates — visibility (6.5%) and tyres (4.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tyre pressure monitoring system and headlamp aim — wipers alone was recorded 202 times.
Condition tracks the odometer closely. Failures run at 9.8% in the 0-30k band and 22.2% in the 90-120k band, a 12.4-point spread — more than double.
Tyres is the most common advisory, noted on 18.6% of tests — work that passed today but is likely due soon.
The trend is worsening — 2.5% of tests failed in 2022 against 14.3% in 2025, the usual pattern as a fleet ages.

| 0-30k | 1,935 | 9.8% |
| 30-60k | 1,047 | 15.3% |
| 60-90k | 201 | 20.4% |
| 90-120k | 36 | 22.2% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2020 Allied
The failure pattern for this year is specific enough to inspect against: visibility accounted for 6.5% of tests. Start there.
- Visibility (6.5% 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.
- Tyres (4.3% 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.
- Lighting & signalling (3.8% 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.
