2022 MG HS — MOT failures & pass rate
21,257 MOT tests on the 2022 MG HS are in this dataset, and 91.8% of them passed. Mid-size SUVs of a similar age fail at 7.6%, so the 2022 HS sits squarely on the average. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (3.5%) and lighting & signalling (3.0%) 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 washers — headlamp aim alone was recorded 659 times.
Mileage is the strongest signal on the record: 6.4% of 0-30k cars fail, rising to 19.1% once past 90-120k — 3.0× the risk.
Split by fuel, petrol examples fail 1.6pp more often than hybrid ones (8.4% vs 6.8%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: brakes was flagged on 20.6% of tests without failing them.
The trend is worsening — 0.0% of tests failed in 2023 against 8.3% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

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 | 14,447 | 6.4% |
| 30-60k | 6,356 | 11.6% |
| 60-90k | 403 | 15.1% |
| 90-120k | 42 | 19.1% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Petrol | 18,349 | 8.4% |
| Hybrid | 2,907 | 6.8% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|

What to check before buying a 2022 HS
On a 2022 HS, tyres is what the MOT record says goes wrong most — it appeared in 3.5% of tests. Check these areas before you commit.
- Tyres (3.5% 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 (3.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.6% 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.
