2016 Infiniti Q70 — MOT failures & pass rate
445 MOT tests on the 2016 Infiniti Q70 are in this dataset, and 88.5% of them passed. Against all cars of a similar age (14.5% fail rate), the 2016 Q70 comes out 3.0pp better. Failures cluster in brakes, tyres and suspension.
What the MOT record shows
No single area dominates — brakes (5.8%) and tyres (4.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, brake pads and service brake performance — tread depth alone was recorded 18 times.
Condition tracks the odometer closely. Failures run at 6.9% in the 0-30k band and 19.1% in the 90-120k band, a 12.3-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 22.7% of tests without failing them.
The trend is worsening — 6.7% of tests failed in 2021 against 14.1% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2016 Q70
On a 2016 Q70, brakes is what the MOT record says goes wrong most — it appeared in 5.8% of tests. Check these areas before you commit.
- Brakes (5.8% 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 (4.7% 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.
- Suspension (3.4% 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.
