Is the Motorhome getting worse?
The fail rate rose 2.7 points to 26.6% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about -0.2 points, so it is getting worse faster than age explains.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 2,201 | 17 | 23.9% | 22.5% | |
| 2023 | 2,160 | 18 | 24.1% | 22.8% | |
| 2024 | 1,802 | 19 | 26.2% | 23.2% | |
| 2025 | 1,902 | 20 | 26.6% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Motorhome at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a Motorhome in 2025, counted by how many tests each one appeared on.
- 1Rbt (sp): efficiency below requirements59 tests
- 2Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength48 tests
- 3Rear fog lamp: not working45 tests
- 4Service brake performance: efficiency below requirements45 tests
- 5Service brake performance: excessively binding45 tests
- 6Wipers: does not clear the windscreen effectively44 tests
- 7Position lamp: not working42 tests
- 8Stop lamp: not working36 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Motorhome collects 2.74 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
- 1Engine oil leaks: leaking excessively from engine141 tests
- 2Rigid brake pipes: excessively corroded135 tests
- 3Condition: has a tear, caused by separation or partial failure of its structure130 tests
- 4Wheel bearings: has excessive play124 tests
- 5Brake discs: in such a condition that it is seriously weakened103 tests
- 6Service brake performance: excessively binding79 tests
- 7Pipes and hoses: excessively corroded75 tests
- 8Tread depth: tread depth below requirements of 1.6mm72 tests
Questions
What is the Fiat Motorhome MOT pass rate?
73.4% of the 1,912 Fiat Motorhome first-attempt MOTs in 2025 passed. The fail rate of 26.6% compares with 22.6% across all cars. A further 4.4% passed after a defect was fixed during the test visit.
What does a Fiat Motorhome usually fail on?
The single most common failure is "Rbt (sp): efficiency below requirements", recorded on 59 failed tests, followed by "Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength" and "Rear fog lamp: not working". By section, lamps, reflectors and electrical equipment appears in 49.8% of failures, brakes appears in 44.1% of failures, body, chassis, structure appears in 26.4% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was 0%; at 14+ years it was 27.8%. The median Fiat Motorhome tested in 2025 was 20 years old with 52,454 miles.
Is the Fiat Motorhome getting less reliable?
The fail rate rose 2.7 points to 26.6% from 2022 to 2025 while the median one tested aged 3 years. Ageing alone would predict about -0.2 points, so it is getting worse faster than age explains.
