The 2006 (362) and 2007 (238) drew the most owner complaints to NHTSA of the 2006–2010 Hummer H3 model years on record, as of November 10, 2026.
2010 has fewer than 40 complaints on file, too few to compare.
NHTSA also holds fewer than 10 complaints and no recall for 2003; that stray filing is left out of the table.
Fewest complaints: not named. Fewer than three of the Hummer H3 model years from 2006 to 2010 with at least 40 complaints on file remain once the years with the most are set aside.
Half of the 614 NHTSA owner complaints on the Hummer H3 that list mileage came after 77,000 miles (NHTSA complaints file of November 11, 2026). How many miles will a Hummer H3 last? →
Hummer H3 complaints and recalls by model year, 2006–2010
This table lists the 5 Hummer H3 model years NHTSA holds records for between 2006 and 2010, collected from NHTSA’s complaints and recalls APIs on November 10, 2026. Each owner complaint is counted once, by its NHTSA number, and a complaint can name more than one component; recall campaigns are counted once per model year, by campaign number. Across these years NHTSA lists 4 distinct recall campaigns, the newest filed Jul 1, 2015.
| Model year | Owner complaints | Most-reported components | Recall campaigns | Newest recall filed |
|---|---|---|---|---|
| 2006 H3 | 362 · most | electrical system (96), engine (52), body structure (36) | 4 | Jul 1, 2015 |
| 2007 H3 | 238 · most | electrical system (76), engine (44), windshield wipers (24) | 2 | Jul 1, 2015 |
| 2008 H3 | 113 | electrical system (34), engine (18), airbags (17) | 2 | Jul 1, 2015 |

Hummer H3 by model year: mileage, problems and recalls
Each page below covers one model year in NHTSA’s complaints file of November 11, 2026: the mileage when owners reported problems, the most-reported components and the recall campaigns NHTSA’s recall files list. That file is a separate collection from the table above and goes back to the 1981 model year, so its counts can differ and it holds years the table does not.
How to read these numbers
- A higher count is not proof of a worse vehicle. Complaint volume rises with sales volume and with years on the road, so older and best-selling years collect more.
- The comparison is between years of the Hummer H3 only. It says nothing about how the H3 compares with other models.
- NHTSA publishes owner reports without verifying them. A complaint is an allegation, not a defect finding.
- Recall campaigns cover production ranges. NHTSA’s VIN lookup checks open recalls within its coverage and excludes completed repairs. A zero result does not prove the vehicle’s complete recall or repair history; ask for dated repair documentation.
- NHTSA files some years under body or cab names (for example ACCESS CAB or CREW CAB). This collection asked for the names NHTSA lists, and a year far below its neighbours also under the common cab and body names. Such a year is marked as possibly filed under another name only when NHTSA’s records show it split across names or holding recalls and no complaint; otherwise its count is read as low.

Hummer H3 year-by-year questions
Which Hummer H3 years should I avoid?
Hummer H3 years to avoid, by NHTSA owner complaints: the 2006 (362 complaints, led by the electrical system at 96 and the engine at 52) and the 2007 (238, led by the electrical system at 76 and the engine at 44) drew the most of the 2006–2010 model years on record as of November 10, 2026; complaints are owner reports, not proven defects, and the counts also reflect each year’s age and sales. 2010 has fewer than 40 complaints on file, too few to compare. NHTSA also holds fewer than 10 complaints and no recall for 2003; that stray filing is left out of the table.
What are the best Hummer H3 years?
Complaint counts do not show which model year is best; the closest they come is which years drew the fewest complaints. This page names none: fewer than three of the Hummer H3 model years from 2006 to 2010 with at least 40 complaints on file remain once the years with the most are set aside.
Do complaint counts mean the H3 is unreliable?
No. NHTSA complaints are unverified owner reports, and the count rises with how many vehicles were sold and how long they have been on the road. They are useful for comparing years of the same model, which is what this page does, not for ranking one model against another.
How do I check a specific H3 before buying?
Take the 17-character VIN from the windshield or driver-door label and run it through NHTSA's free recall lookup. It reports open recalls within its coverage and excludes completed repairs. A zero result is not a complete recall or repair history; ask the seller or manufacturer for dated repair documentation. For the vehicle's own past, the original ClearVIN PDF from VIN Lookup shows title brands, odometer readings, accident and auction records on file for that VIN.
