Fiat Motor-Home MOT pass rate & common failures
4,397 MOT tests on the Fiat Motor-Home (1986–2020) give it a 79.5% pass rate. That is 5.5 percentage points better than all cars of a similar age, which fail at 25.9%. Its most common failure areas are lighting & signalling, brakes and visibility.
What the MOT record shows
Lighting & signalling dominates the failure mix at 14.4% of all tests — 6.0 points clear of brakes, so it is the first thing to check.
At component level the recurring items are headlamp aim, service brake performance and wipers — headlamp aim alone was recorded 241 times.
A 150k+ example is materially riskier than a 0-30k one: 30.0% versus 16.1%.
Advisories point at the next bill rather than this one: brakes was flagged on 20.7% of tests without failing them.
The trend is worsening — 19.8% of tests failed in 2021 against 21.6% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a Fiat Motor-Home
- Lighting & signalling (14.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.4% 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.
- Visibility (5.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
