2020 Fiat Ducato 42 Maxi Power — MOT failures & pass rate
The 2020 Fiat Ducato 42 Maxi Power passed 95.7% of its 1,059 recorded MOT tests. Against all cars of a similar age (8.0% fail rate), the 2020 Ducato 42 Maxi Power comes out 3.7pp better. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 5.9% of all tests — 4.2 points clear of suspension, so it is the first thing to check.
At component level the recurring items are headlamp aim, ball joint and rbt (sp) — headlamp aim alone was recorded 68 times.
Condition tracks the odometer closely. Failures run at 0.0% in the 0-30k band and 5.2% in the 150k+ band, a 5.2-point spread — more than double.
Advisories point at the next bill rather than this one: suspension was flagged on 10.2% of tests without failing them.
The trend is worsening — 2.5% of tests failed in 2021 against 6.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2020 Ducato 42 Maxi Power
On a 2020 Ducato 42 Maxi Power, lighting & signalling is what the MOT record says goes wrong most — it appeared in 5.9% of tests. Check these areas before you commit.
- Lighting & signalling (5.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (1.8% 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 (1.7% 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.
