Fiat Motorhome MOT Failures
An analysis of 23,290 real DVSA MOT tests on the Fiat Motorhome — what fails, how often, and how that compares to every other car on UK roads.
Where the Fiat Motorhome fails its MOT
The single biggest MOT failure point on the Fiat Motorhome is lamp missing, inoperative or in the case of a m... — this model is 136 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 23,290 MOT tests, 3.26% of all Fiat Motorhome tests recorded this as a failure.
Lighting faults are usually straightforward to fix (bulbs, connectors, earth points) but can indicate deeper wiring issues on older cars. Check all lights including fog lamps, number plate lights, and dashboard warning lights.
Other notable weak points include power steering fault (125x the fleet average), structural corrosion (47x the fleet average), wheel bearings worn (39x the fleet average), and subframe bushes or mounts worn (57x the fleet average). These ratios compare the Fiat Motorhome's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 5 categories: Lights & Electrics, Steering, Bodywork, Suspension, Brakes. If you're inspecting a Fiat Motorhome before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Fiat Motorhome's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Fiat Motorhome specifically, the DVSA data shows the most common failures at this mileage are lamp missing, inoperative or in the case of a m... (132x the average) and power steering fault (125x). light unit fault (85x) and subframe bushes or mounts worn (57x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Fiat Motorhome specifically, the DVSA data shows the most common failures at this mileage are lamp missing, inoperative or in the case of a m... (97x the average) and power steering fault (74x). wheel bearings worn (29x) and service brake efficiency below minimum requirement (18x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
The standout failure at this mileage is wheel bearings worn at 18x the fleet average.
The shift from lamp missing, inoperative or in the case of a m... at lower mileages to wheel bearings worn at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
What to check before buying a Fiat Motorhome
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Fiat Motorhome:
Lights & Electrics — check for lamp missing, inoperative or in the case of a m..., light unit fault. Steering — check for power steering fault. Bodywork — check for structural corrosion, vehicle structure corroded to the extent that t.... Suspension — check for wheel bearings worn, subframe bushes or mounts worn.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. Enter any reg into our free car check to see the complete picture.
