Mazda Eunos MOT Failures
An analysis of 3,315 real DVSA MOT tests on the Mazda Eunos — what fails, how often, and how that compares to every other car on UK roads.
Where the Mazda Eunos fails its MOT
The single biggest MOT failure point on the Mazda Eunos is suspension component damaged or corroded — this model is 15 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 3,315 MOT tests, 16.38% of all Mazda Eunos 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 suspension joint dust cover severely deteriorated (13x the fleet average), seat mounting fault (19x the fleet average), track rod ends worn (15x the fleet average), and structural corrosion (12x the fleet average). These ratios compare the Mazda Eunos'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 6 categories: Suspension, Seatbelts & Airbags, Steering, Bodywork, Lights & Electrics and others. If you're inspecting a Mazda Eunos 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 Mazda Eunos'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.
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 Mazda Eunos specifically, the DVSA data shows the most common failures at this mileage are structural corrosion (12x the average) and suspension joint dust cover severely deteriorated (12x). suspension component damaged or corroded (5.4x) and suspension component damaged or corroded also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Mazda Eunos specifically, the DVSA data shows the most common failures at this mileage are seat mounting fault (19x the average) and track rod ends worn (15x). suspension component damaged or corroded (15x) and suspension joint dust cover severely deteriorated (13x) also appear frequently.
The shift from structural corrosion at lower mileages to seat mounting fault at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
What to check before buying a Mazda Eunos
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Mazda Eunos:
Suspension — check for suspension component damaged or corroded, suspension joint dust cover severely deteriorated, suspension joint dust cover missing or no longe.... Seatbelts & Airbags — check for seat mounting fault. Steering — check for track rod ends worn.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. Enter any reg into our free car check to see the complete picture.
