The Hummer H3 MOT pass rate is 85.3%, +4.3 percentage points above the UK average. That is 361 DVSA MOT tests recorded between 2006 and 2009. This page lists the most common Hummer H3 MOT failures by category, names the best and worst model years, and finishes with a pre-MOT checklist you can run at home.
The Hummer H3 passed on its first attempt in 83.8%, and its overall record sits +4.3 percentage points above the national average for all cars. These figures come from every recorded DVSA MOT test for the Hummer H3 in the 2023–2025 data: 361 tests across 4 model years (2006–2009). A test still carries exactly one pass or fail verdict.

Figures are computed from every recorded DVSA test for this model in the 2023–2025 data.
Every MOT failure a tester records belongs to one inspection section of the DVSA manual. For the Hummer H3, the Lamps, reflectors and electrical equipment section leads the record — the breakdown below shows where the recorded failures cluster, then the exact strings behind the three biggest sections.
| Inspection section | Share of failures |
|---|---|
| Lamps, reflectors and electrical equipment | 44% |
| Noise, emissions and leaks | 16% |
| Body, chassis, structure | 11% |
| Visibility | 10% |
| Suspension | 10% |
| Brakes | 6% |
| Steering | 2% |
Shares are over the Hummer H3's recorded defect strings, merged across its year pages.
Around 44% of the recorded Hummer H3 failures fall in the Lamps, reflectors and electrical equipment section of the MOT inspection manual. Testers recorded "Battery(ies) insecure but not likely to fall from carrier" (2.5%), "Registration plate lamp(s) inoperative in the case of multiple lamps or light sources" (1.9%), "Headlamp aim too low" (1.7%) among the Hummer H3's lamps, reflectors and electrical equipment faults.
Around 16% of the recorded Hummer H3 failures fall in the Noise, emissions and leaks section of the MOT inspection manual. Testers recorded "Malfunction indicator lamp inoperative or indicates a malfunction" (4.2%), "Catalyst emissions Lambda reading after 2nd fast idle outside specified limits" (1.4%) among the Hummer H3's noise, emissions and leaks faults.
Around 11% of the recorded Hummer H3 failures fall in the Body, chassis, structure section of the MOT inspection manual. Testers recorded "Joints constant velocity boot severely deteriorated" (3.3%), "Door condition cannot be opened from outside the vehicle" (0.6%) among the Hummer H3's body, chassis, structure faults.
The descriptions below are the exact DVSA failure strings testers recorded most often for the Hummer H3, each with how many of the model's 361 tests it was noted on.
The strongest Hummer H3 model year on record is 2008 (94.2% across 104 tests), and the weakest is 2007 (77.6%). The gap between them is 16.6 points. Years with fewer than 50 recorded tests are excluded, so these are the years with enough MOT history to mean something.
Hummer H3 reliability is improving in the DVSA data — the pass rate moves about 3.3 points a year across the most recent model years shown above.
Newest model year first. Only years with at least 50 recorded tests are listed.
These checks follow this Hummer H3's own most-recorded failure strings, starting with what a tester is most likely to flag on a Hummer H3.
the lights — “malfunction indicator lamp inoperative or indicates a malfunction”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
the battery — “battery(ies) insecure”
Check the battery is secure and its terminals are clean and tight — a loose battery is a fail on its own, and a weak one shows up as slow cranking on a cold morning.
the windscreen — “windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Derived from the DVSA failure strings testers recorded for the Hummer H3. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
85.3% of the 361 recorded Hummer H3 MOT tests ended in a pass, +4.3 percentage points above the national average. 83.8% of those passed on the first attempt.
2008 is the strongest Hummer H3 year on record at 94.2%, while 2007 is the weakest at 77.6%. The year-by-year table below lists every model year with at least 50 recorded tests.
The most recorded Hummer H3 failures are "Malfunction indicator lamp inoperative or indicates a malfunction" and "Joints constant velocity boot severely deteriorated" — together around 7% of tests, mostly in the Noise, emissions and leaks section.
