2001 Mazda Eunos — MOT failures & pass rate
Across 403 MOT tests, the 2001 Mazda Eunos recorded a 72.0% pass rate. That is effectively the same as all cars of a similar age (27.1% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (14.4%) and brakes (13.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, rear fog lamp and service brake performance — catalyst emissions alone was recorded 51 times.
Mileage is the strongest signal on the record: 23.1% of 60-90k cars fail, rising to 33.3% once past 150k.
Brakes is the most common advisory, noted on 29.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 25.9% in 2021 to 22.4% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 29.3% | 118 |
| 2 | Suspension | 27.3% | 110 |
| 3 | Emissions & environmental | 26.3% | 106 |
| 4 | Tyres | 14.6% | 59 |
| 5 | Body, structure & corrosion | 10.4% | 42 |
| 6 | Lighting & signalling | 6.7% | 27 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 78 | 23.1% |
| 90-120k | 92 | 30.4% |
| 120-150k | 93 | 24.7% |
| 150k+ | 132 | 33.3% |
Failure rate by age
Trend over time

What to check before buying a 2001 Eunos
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 14.4% of tests. Start there.
- Lighting & signalling (14.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (13.4% 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 (10.2% 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.
