2001 Mazda E Series — MOT failures & pass rate
Across 741 MOT tests, the 2001 Mazda E Series recorded a 70.9% pass rate. That is 2.1 percentage points worse than all cars of a similar age, which fail at 27.0%. Failures cluster in suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (15.4%) and lighting & signalling (13.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, chassis condition and service brake performance — component mounting prescribed areas alone was recorded 119 times.
Mileage matters less than usual here: the 2001 E Series fails 30.2% of the time in the 30-60k band and 32.1% at 150k+, a spread of only 1.8 points.
Advisories point at the next bill rather than this one: suspension was flagged on 38.7% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 38.7% | 287 |
| 2 | Brakes | 28.6% | 212 |

| 5 | Emissions & environmental | 15.1% | 112 |
| 6 | Steering | 14.8% | 110 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

What to check before buying a 2001 E Series
On a 2001 E Series, suspension is what the MOT record says goes wrong most — it appeared in 15.4% of tests. Check these areas before you commit.
- Suspension (15.4% 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.
- Lighting & signalling (13.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (10.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
