2014 Infiniti Qx70 — MOT failures & pass rate
817 MOT tests on the 2014 Infiniti Qx70 are in this dataset, and 88.7% of them passed. Against all cars of a similar age (18.4% fail rate), the 2014 Qx70 comes out 7.1pp better. Failures cluster in brakes, tyres and suspension.
What the MOT record shows
No single area dominates — brakes (3.2%) and tyres (3.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are ball joint, malfunction indicator lamp and wipers — ball joint alone was recorded 21 times.
Mileage is the strongest signal on the record: 6.9% of 30-60k cars fail, rising to 15.2% once past 120-150k — 2.2× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 18.0% of tests without failing them.
The trend is worsening — 7.1% of tests failed in 2021 against 13.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2014 Qx70
On a 2014 Qx70, brakes is what the MOT record says goes wrong most — it appeared in 3.2% of tests. Check these areas before you commit.
- Brakes (3.2% 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.
- Tyres (3.2% 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.
- Suspension (2.9% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
