2017 Nissan 370 Z — MOT failures & pass rate
400 MOT tests on the 2017 Nissan 370 Z are in this dataset, and 93.5% of them passed. That is 6.6 percentage points better than all cars of a similar age, which fail at 13.1%. Failures cluster in tyres, emissions & environmental and visibility.
What the MOT record shows
No single area dominates — tyres (2.8%) and emissions & environmental (1.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, catalyst emissions and wipers — tread depth alone was recorded 10 times.
Advisories point at the next bill rather than this one: tyres was flagged on 13.8% of tests without failing them.
The trend is worsening — 4.6% of tests failed in 2021 against 7.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2017 370 Z
On a 2017 370 Z, tyres is what the MOT record says goes wrong most — it appeared in 2.8% of tests. Check these areas before you commit.
- Tyres (2.8% 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 (1.8% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Visibility (1.8% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
