Unclassified problem on the 2005 Hummer H2
1 injury 1 of the 9 reports for this failure mention a crash, a fire, an injury or a death. Those are the owner's words on the complaint form, not a verified finding, and one report can mention more than one.
Only 6 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.
When unclassified problem gets reported
There are 9 reports of unclassified problem on the 2005 Hummer H2, 6 with a mileage attached. That is too few to place the failure on the odometer with any confidence.
It is the 31st most-reported problem on this model year.
The whole distribution
| 10th | 25th | Median | 75th | 90th |
|---|---|---|---|---|
| — | — | 99,500 miles | — | — |
Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.
What a percentile can and cannot tell you here
These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.
What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.
Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.
What happens, and what it costs
Of these reports, 1 an injury is mentioned. Owners write their own complaints and the agency does not verify them, so read this as what the reports say happened rather than as a confirmed count.
The same failure on other years
The same failure is reported on 5 model years of this car. It shows up earliest on the 2006, at a median of 40,000 miles, and latest on the 2005 at 100,000 miles.
By volume the 2005 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.
If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote
Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.
Tl* the contact owns a 2005 hummer h2. The contact stated that while driving at various speeds, the air bag warning light illuminated and a message appeared stating that the air bag needed to be serviced. The vehicle was not inspected by a dealer or an independent mechanic. The manufacturer was contacted and they offered no assistance. The failure and current mileages were approximately 130,000. The VIN was unavailable.
A problem with nearly all hummer h2s is roof leak, there is a drainage system to drain the water thru the vehicle. This clogs up periodically and the water drains into the vehicle and ends up on the front floorboard. The airbag sensor diagnostic module is mounted on the floorboard directly under the drivers seat. If this gets wet, which it does, the module is ruined and renders the airbags inoperable. This has happened to my vehicle and I am sure many others. If this module is not in working order it has to be replaced, however, general motors has discontinued making the airbag sensor diagnostic module for the 2005 hummer h2 model year!. I am sure I am not the only person (owner) caught up in this situation. The vehicle is still operative and drivable. Airbag sensor diagnostic module should be available and manufacture should ensure it is available. The vehicle is only 10 years old and if I owned a prior year the module is still available. It is a safety issue because of where it is located in the vehicle and manufacture knowledge of leak problems, and only one year discontinued. I have contacted general motors and there reply was…
There has to be a recall done on the 2005 hummer h2 airbag module. When it rains the water gets in to vehicle from the driver side. I see a lot of complaints from other people that have the same issue. I have currently only 61,000 miles on my hummer h2. Never got in a accident. Only issue is the water coming in from the driver side and damaged the air bag module. The part # is 12249649, and it only works on the 2005 no other year modules will work. The part is discontinued from gm.

How far this goes
This page is kept out of search results because 9 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.
Complaints are voluntary, so 9 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.
Questions this page answers
At what mileage does unclassified problem happen on the 2005 Hummer H2?
Across 6 owner reports that included an odometer reading, half were filed by 100,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.
How common is unclassified problem on the 2005 Hummer H2?
9 reports have been filed with NHTSA, about 0.2 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.
What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
