Hummer H2 MOT pass rate & common failures
Across 22 model years and 1,082 tests, the Hummer H2 passes its MOT 88.5% of the time. That is 14.8 percentage points better than all cars of a similar age, which fail at 26.3%. Its most common failure areas are lighting & signalling, emissions & environmental and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (7.0%) and emissions & environmental (5.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, headlamp aim and rear fog lamp — catalyst emissions alone was recorded 31 times.
Mileage matters less than usual here: the H2 fails 9.8% of the time in the 0-30k band and 13.6% at 120-150k, a spread of only 3.8 points.
Brakes is the most common advisory, noted on 15.9% 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 | Brakes | 15.9% | 172 |
| 2 | Suspension | 12.0% | 130 |
| 3 | Steering | 9.4% | 102 |

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 | 153 | 9.8% |
| 30-60k | 316 | 10.8% |
| 60-90k | 352 | 9.4% |

What to check before buying a Hummer H2
- Lighting & signalling (7.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (5.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Brakes (4.0% 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.
