2022 MG MG5 — MOT failures & pass rate
Across 14,127 MOT tests, the 2022 MG MG5 recorded a 90.6% pass rate. All cars of a similar age fail 7.3% of the time, so this is 2.0pp worse than the group it competes with. Failures cluster in lighting & signalling, tyres and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (7.4%) and tyres (5.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp, tread depth and shock absorbers — headlamp alone was recorded 711 times.
A 150k+ example is materially riskier than a 0-30k one: 16.2% versus 6.0%.
Advisories point at the next bill rather than this one: tyres was flagged on 20.3% of tests without failing them.
The trend is worsening — 0.0% of tests failed in 2022 against 10.7% 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 |
|---|---|---|---|
| 1 | Tyres | 20.3% | 2,861 |
| 2 | Suspension | 12.0% | 1,692 |
| 3 | Other defects | 4.7% | 665 |

| 5 | Brakes | 2.4% | 333 |
| 6 | Visibility | 1.5% | 218 |
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 | 5,386 | 6.0% |
| 30-60k | 5,658 | 9.7% |
| 60-90k | 2,232 | 14.1% |
| 90-120k | 677 | 16.4% |
| 120-150k | 137 | 13.9% |
| 150k+ | 37 | 16.2% |

What to check before buying a 2022 MG5
On a 2022 MG5, lighting & signalling is what the MOT record says goes wrong most — it appeared in 7.4% of tests. Check these areas before you commit.
- Lighting & signalling (7.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.5% 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.
- Suspension (3.1% 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.
