2004 Fiat Motorhome. — MOT failures & pass rate
The 2004 Fiat Motorhome. passed 77.7% of its 1,294 recorded MOT tests. All cars of a similar age fail 27.7% of the time, so this is 5.4pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 14.8% of tests against 8.8% for the next-worst category.
At component level the recurring items are wipers, component mounting prescribed areas and service brake performance — wipers alone was recorded 71 times.
Condition tracks the odometer closely. Failures run at 16.0% in the 0-30k band and 28.2% in the 120-150k band, a 12.3-point spread.
Brakes is the most common advisory, noted on 22.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 21.0% of tests failed in 2021 against 25.4% in 2025, the usual pattern as a fleet ages.

| 5 | Tyres | 9.1% | 118 |
| 6 | Steering | 7.4% | 96 |
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 | 94 | 16.0% |
| 30-60k | 745 | 20.4% |
| 60-90k | 313 | 25.9% |
| 90-120k | 87 | 29.9% |
| 120-150k | 39 | 28.2% |

What to check before buying a 2004 Motorhome.
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.8% of tests. Start there.
- Lighting & signalling (14.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.8% 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.
- Body, structure & corrosion (6.0% 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.
