Infiniti Q70 MOT Failures
An analysis of 1,503 real DVSA MOT tests on the Infiniti Q70 — what fails, how often, and how that compares to every other car on UK roads.
Where the Infiniti Q70 fails its MOT
The single biggest MOT failure point on the Infiniti Q70 is anti-roll bar links worn — this model is 25 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 1,503 MOT tests, 14.3% of all Infiniti Q70 tests recorded this as a failure.
Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.
Other notable weak points include excessive fluctuation in brake effort through e... (5.9x the fleet average) and suspension pin, bush or joint worn (5.4x the fleet average). These ratios compare the Infiniti Q70's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 2 categories: Suspension, Brakes. If you're inspecting a Infiniti Q70 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Infiniti Q70's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Infiniti Q70 specifically, the DVSA data shows the most common failures at this mileage are anti-roll bar links worn (16x the average) and excessive fluctuation in brake effort through e... (5.9x).
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Infiniti Q70 specifically, the DVSA data shows the most common failures at this mileage are anti-roll bar links worn (25x the average) and suspension pin, bush or joint worn (5.4x).
