1999 Fiat Motorhome. — MOT failures & pass rate
Across 534 MOT tests, the 1999 Fiat Motorhome. recorded a 72.5% pass rate. That is 1.5 percentage points worse than all cars of a similar age, which fail at 26.1%. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 17.0% of tests against 11.6% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, position lamp and service brake performance — component mounting prescribed areas alone was recorded 48 times.
Condition tracks the odometer closely. Failures run at 21.5% in the 30-60k band and 35.1% in the 120-150k band, a 13.6-point spread.
Suspension is the most common advisory, noted on 37.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 31.5% in 2021 to 19.5% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 37.3% | 199 |
| 2 | Brakes | 24.7% | 132 |
| 3 | Body, structure & corrosion | 22.1% | 118 |

| 5 | Emissions & environmental | 12.6% | 67 |
| 6 | Lighting & signalling | 12.4% | 66 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 195 | 21.5% |
| 60-90k | 173 | 26.6% |
| 90-120k | 105 | 37.1% |
| 120-150k | 37 | 35.1% |

What to check before buying a 1999 Motorhome.
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 17.0% of tests. Start there.
- Lighting & signalling (17.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.6% 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 (10.5% 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.
