Infiniti Q70 MOT pass rate & common failures
The Infiniti Q70 appears in 2,154 MOT tests spanning model years 2013–2019, and 86.8% of them passed. That is 1.4 percentage points better than all cars of a similar age, which fail at 14.6%. Its most common failure areas are tyres, brakes and suspension.
What the MOT record shows
No single area dominates — tyres (5.3%) and brakes (5.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake pads, tread depth and wipers — brake pads alone was recorded 70 times.
A 150k+ example is materially riskier than a 0-30k one: 21.1% versus 6.4%.
Tyres is the most common advisory, noted on 24.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 9.0% of tests failed in 2021 against 15.7% in 2025, the usual pattern as a fleet ages.

What to check before buying a Infiniti Q70
- Tyres (5.3% 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.
- Brakes (5.1% 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.
- Suspension (3.2% 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.
