Infiniti Qx70 MOT pass rate & common failures
2,253 MOT tests on the Infiniti Qx70 (2012–2020) give it a 90.2% pass rate. All cars of a similar age fail 16.4% of the time, so this is 6.6pp better than the group it competes with. Its most common failure areas are tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (3.5%) and lighting & signalling (2.8%) 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 brake pads — malfunction indicator lamp alone was recorded 41 times.
Mileage matters less than usual here: the Qx70 fails 9.7% of the time in the 0-30k band and 13.0% at 120-150k, a spread of only 3.3 points.
Tyres is the most common advisory, noted on 18.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.2% of tests failed in 2021 against 11.1% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

What to check before buying a Infiniti Qx70
- Tyres (3.5% 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 (2.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.3% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
