2019 MG HS — MOT failures & pass rate
414 MOT tests on the 2019 MG HS are in this dataset, and 92.3% of them passed. Mid-size SUVs of a similar age fail 9.6% of the time, so this is 1.9pp better than the group it competes with. Failures cluster in tyres, brakes and visibility.
What the MOT record shows
No single area dominates — tyres (3.4%) and brakes (3.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, brake discs and brake pads — headlamp aim alone was recorded 10 times.
Advisories point at the next bill rather than this one: brakes was flagged on 22.2% of tests without failing them.
The trend is worsening — 4.2% of tests failed in 2022 against 12.7% 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 | Brakes | 22.2% | 92 |
| 2 | Tyres | 14.0% | 58 |
| 3 | Other defects | 8.5% | 35 |
| 4 | Suspension | 3.6% | 15 |
| 5 | Lighting & signalling | 1.0% | 4 |
| 6 | Emissions & environmental | 0.5% | 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 | 224 | 6.7% |
| 30-60k | 173 | 9.3% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2022 | 95 | 4.2% |
| 2023 | 98 | 7.1% |
| 2024 | 101 | 5.9% |
| 2025 | 118 | 12.7% |
What to check before buying a 2019 HS
On a 2019 HS, tyres is what the MOT record says goes wrong most — it appeared in 3.4% of tests. Check these areas before you commit.
- Tyres (3.4% 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.
- Brakes (3.4% 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.
- Visibility (2.2% 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.
