2019 Fiat 500X — MOT failures & pass rate
14,622 MOT tests on the 2019 Fiat 500X are in this dataset, and 91.8% of them passed. Small SUVs of a similar age fail at 8.9%, so the 2019 500X sits squarely on the average. Failures cluster in tyres, emissions & environmental and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.3%) and emissions & environmental (1.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, headlamp aim and catalyst emissions — tread depth alone was recorded 345 times.
Condition tracks the odometer closely. Failures run at 5.6% in the 0-30k band and 22.8% in the 90-120k band, a 17.2-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 25.0% of tests without failing them.
The trend is worsening — 4.2% of tests failed in 2021 against 11.0% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2019 500X
On a 2019 500X, tyres is what the MOT record says goes wrong most — it appeared in 4.3% of tests. Check these areas before you commit.
- Tyres (4.3% 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.
- Emissions & environmental (1.9% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Lighting & signalling (1.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
