2016 Infiniti Qx70 — MOT failures & pass rate
The 2016 Infiniti Qx70 passed 91.1% of its 750 recorded MOT tests. Against all cars of a similar age (14.5% fail rate), the 2016 Qx70 comes out 5.6pp better. Failures cluster in tyres, emissions & environmental and visibility.
What the MOT record shows
No single area dominates — tyres (3.7%) and emissions & environmental (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, wipers and brake pads — tread depth alone was recorded 18 times.
Mileage is the strongest signal on the record: 8.1% of 0-30k cars fail, rising to 12.3% once past 90-120k.
Advisories point at the next bill rather than this one: tyres was flagged on 19.6% of tests without failing them.
The trend is worsening — 5.4% of tests failed in 2021 against 8.5% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2016 Qx70
On a 2016 Qx70, tyres is what the MOT record says goes wrong most — it appeared in 3.7% of tests. Check these areas before you commit.
- Tyres (3.7% 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 (2.1% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Visibility (2.0% 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.
