2018 Fiat Fiorino — MOT failures & pass rate
The 2018 Fiat Fiorino passed 80.9% of its 2,512 recorded MOT tests. That is 3.0 percentage points worse than vans of a similar age, which fail at 16.1%. Failures cluster in lighting & signalling, tyres and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (8.4%) and tyres (7.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are malfunction indicator lamp, headlamp aim and shock absorbers — malfunction indicator lamp alone was recorded 93 times.
Condition tracks the odometer closely. Failures run at 16.4% in the 0-30k band and 24.4% in the 150k+ band, a 8.0-point spread.
Advisories point at the next bill rather than this one: tyres was flagged on 24.9% of tests without failing them.
The trend is worsening — 14.6% of tests failed in 2021 against 18.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2018 Fiorino
On a 2018 Fiorino, lighting & signalling is what the MOT record says goes wrong most — it appeared in 8.4% of tests. Check these areas before you commit.
- Lighting & signalling (8.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (7.0% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Suspension (5.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
