Fiat Ducato 42 Maxi Power MOT pass rate & common failures
The Fiat Ducato 42 Maxi Power appears in 3,869 MOT tests spanning model years 2020–2024, and 95.0% of them passed. That is 2.0 percentage points better than all cars of a similar age, which fail at 7.0%. Its most common failure areas are lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 8.3% of all tests — 6.3 points clear of suspension, so it is the first thing to check.
At component level the recurring items are headlamp aim, ball joint and outline marker lamp — headlamp aim alone was recorded 390 times.
Mileage matters less than usual here: the Ducato 42 Maxi Power fails 2.8% of the time in the 0-30k band and 4.3% at 150k+, a spread of only 1.5 points.
Advisories point at the next bill rather than this one: suspension was flagged on 8.0% of tests without failing them.
The trend is worsening — 2.4% of tests failed in 2021 against 4.7% in 2025, the usual pattern as a fleet ages.

What to check before buying a Fiat Ducato 42 Maxi Power
- Lighting & signalling (8.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (2.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (2.0% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
