2022 Mazda 6 — MOT failures & pass rate
448 MOT tests on the 2022 Mazda 6 are in this dataset, and 94.6% of them passed. That is 4.7 percentage points better than large family cars of a similar age, which fail at 10.0%. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (2.5%) and lighting & signalling (2.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, brake pads and service brake performance — headlamp aim alone was recorded 9 times.
Advisories point at the next bill rather than this one: tyres was flagged on 9.8% of tests without failing them.

| # | Failure item | Times recorded |
|---|---|---|
| 1 | Headlamp aim | 9 |

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 | 9.8% | 44 |
| 2 | Brakes | 8.7% | 39 |
| 3 | Other defects | 5.4% | 24 |
| 4 | Visibility | 1.6% | 7 |
| 5 | Suspension | 0.4% | 2 |
| 6 | Lighting & signalling | 0.4% | 2 |
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 | 231 | 3.5% |
| 30-60k | 202 | 7.4% |
What to check before buying a 2022 6
On a 2022 6, tyres is what the MOT record says goes wrong most — it appeared in 2.5% of tests. Check these areas before you commit.
- Tyres (2.5% 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 (2.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (1.6% 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.
