2013 Infiniti Fx30D — MOT failures & pass rate
631 MOT tests on the 2013 Infiniti Fx30D are in this dataset, and 84.2% of them passed. All cars of a similar age fail 20.0% of the time, so this is 4.1pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — tyres (7.1%) and lighting & signalling (6.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are malfunction indicator lamp, tread depth and position lamp — malfunction indicator lamp alone was recorded 28 times.
Mileage matters less than usual here: the 2013 Fx30D fails 12.3% of the time in the 30-60k band and 15.4% at 150k+, a spread of only 3.1 points.
Advisories point at the next bill rather than this one: tyres was flagged on 19.7% of tests without failing them.
The trend is worsening — 15.9% of tests failed in 2021 against 18.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2013 Fx30D
On a 2013 Fx30D, tyres is what the MOT record says goes wrong most — it appeared in 7.1% of tests. Check these areas before you commit.
- Tyres (7.1% 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.
- Lighting & signalling (6.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (4.8% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
