Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
No new NHTSA visibility complaint has been filed on this vehicle in over 17 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering visibility on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This Preliminary information communicates to the technician the need to inspect the induction system for potential icing issues in very cold ambient temperatures. To allow the ice to melt so that it can be drained from the related components. That any of the listed DTC's may set with or without poor engine performance.

The failure pattern owners describe
Owners of 2005 H2s consistently report windshield wiper and washer failures tied to water entering the wiper motor control module. The failure mode varies: some experience complete loss of wiper function (leaving them driving 30 miles in heavy rain with no visibility), while others get uncontrolled operation—wipers activating on their own in the off position, washer fluid spraying continuously until the reservoir empties, and no driver input shutting them down short of pulling the fuse.
Failures occur across mileage ranges (41,000–79,000 miles reported), and some owners report repeat failures within months of repair. One owner replaced the module three times in five years, with the third failure happening just a month after the previous fix. Dealers consistently diagnose water intrusion and corrosion inside the module, quoting $250–$500 for replacement. GM issued recalls 08V456000 and 08243 addressing this exact issue in other model years (2003–2004 and 2006–2008), but multiple 2005 owners state their VINs were excluded despite identical symptoms. A separate complaint describes significant wind noise through the sunroof starting early in ownership, which persisted after dealer attempted tightening and sealing repairs.
Failure modes owners describe
Windshield wiper motor/module failure—complete loss of function
Wipers stop working entirely, leaving drivers without visibility control during rain or snow. Water enters the wiper motor control module, corroding internal components and causing total failure.
When: 41,000–79,000 miles; failures reported across multiple years of ownership; one owner experienced three failures in five years with the third occurring within a month of the previous repair
Symptoms owners cite: Wipers stop completely and will not respond to driver input; No warning before failure occurs; Extremely limited visibility when failure happens in rain or inclement weather
Repairs/costs cited: Replacement of windshield wiper motor control module; dealer estimates $250–$500 for repair; owners report repeated failures requiring multiple replacements
Recalls/TSBs owners mention: GM Recall 08V456000 (NHTSA 08V456000) addresses water intrusion into wiper motor module for some 2003–2008 H2 model years; however, many 2005 owners report their VINs excluded from recall despite identical symptoms; GM also issued Recall 08243 but similarly excluded some affected 2005 models
Windshield wiper motor/module—intermittent operation
Wipers work unpredictably, cycling on and off without driver command or failing to respond to activation. Water infiltration degrades module performance gradually before complete failure.
When: Multiple occurrences reported from 70,000 miles onward; intermittent symptoms reported as precursor to complete failure within weeks or months
Symptoms owners cite: Wipers cycle on and off randomly, sometimes continuously; Wipers activate on their own even when control is in off position; Wipers fail to turn off when activated; Driver unable to control wipers once malfunction begins
Repairs/costs cited: Module replacement required; interim workaround is to remove wiper fuse to disable uncontrolled operation; repair cost approximately $250–$500
Recalls/TSBs owners mention: Same as above—Recall 08V456000 and 08243 excluded many 2005 VINs despite identical failure modes reported in 2003–2004 and 2006–2008 model years
Windshield washer pump—uncontrolled operation
Washer pump operates continuously or activates on its own, independent of driver control. Water intrusion into the motor control module causes pump to spray fluid unprompted, draining the reservoir.
When: Occurs concurrently with wiper failures; reported at 72,000 miles and beyond
Symptoms owners cite: Washer fluid sprays without driver activation; Pump continues spraying after all fluid is depleted; Driver cannot stop pump operation except by removing fuse
Repairs/costs cited: Module replacement; temporary fix is fuse removal; estimated repair $250–$500
Recalls/TSBs owners mention: Covered under Recall 08V456000 for affected VINs (water intrusion in wiper/washer motor module); many 2005 owners excluded from recall
Sunroof wind noise—audible air leak
Significant wind tunnel noise emanates from the sunroof when it is closed, loud enough to prevent radio listening. Dealer attributes noise to loose sunroof retainer or sealing issues.
When: Reported as early as 3–5 months of ownership (March–May 2005)
Symptoms owners cite: Loud wind noise coming through sunroof; Noise prevents normal radio use
Repairs/costs cited: Dealer tightened sunroof retainer and applied double-sided tape; noise persisted after both repair attempts
Recalls/TSBs owners mention: Service manager acknowledged multiple complaints about this noise and stated it was a known issue; no formal recall or service bulletin documented in narratives

Windshield wipers work intermittently, come on by themselves, then won't shut off. The problem has happened 5 times in 3 days. Same problems as the 2003 recall for same item.....dealer said water in motor and or module causing problem . Have to be replaced. Waiting to here from gm assistance. *tr

Common questions
How serious is the visibility problem on the 2005 Hummer H2?
It's a documented issue but not catastrophic. 16 complaints have been filed. Repairs average $350 and most owners catch it before it causes a breakdown.
At what mileage does the visibility typically fail?
Across the 15 complaints that reported odometer mileage, most visibility failures cluster between 49,750 and 80,000 miles, with the median around 65,000. A quarter of owners report trouble before 49,750; a quarter make it past 80,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $350 for visibility repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to visibility?
No active recalls currently cover visibility issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
