2022 Mazda CX-30 — MOT failures & pass rate
Across 6,744 MOT tests, the 2022 Mazda CX-30 recorded a 95.1% pass rate. Small SUVs of a similar age fail 6.6% of the time, so this is 1.7pp better than the group it competes with. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (2.8%) and lighting & signalling (1.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and brake pads — headlamp aim alone was recorded 110 times.
Mileage is the strongest signal on the record: 3.6% of 0-30k cars fail, rising to 11.4% once past 60-90k — 3.1× the risk.
Tyres is the most common advisory, noted on 15.8% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 15.8% | 1,066 |
| 2 | Brakes | 15.3% | 1,032 |

| 5 | Visibility | 2.1% | 142 |
| 6 | Lighting & signalling | 0.2% | 12 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 5,127 | 3.6% |
| 30-60k | 1,539 | 8.7% |
| 60-90k | 70 | 11.4% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Petrol | 6,635 | 4.9% |
| Hybrid | 109 | 4.6% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2022 CX-30
The failure pattern for this year is specific enough to inspect against: tyres accounted for 2.8% of tests. Start there.
- Tyres (2.8% 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.
- Lighting & signalling (1.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.3% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
