Which Hummer model has the most NHTSA complaints?
By total complaint volume, the top Hummer models are: Hummer H3 (1,062 complaints), Hummer H2 (429 complaints), Hummer H1 (8 complaints). Note that higher-volume models naturally accumulate more complaints, so per-model severity depends on sales volume and crash rate. See the full sortable ranking at vinitel.com/stats/nhtsa-complaints/hummer.
What are the most common Hummer problems?
Across all Hummer models in the NHTSA database, the most-reported issue categories are: Electrical Faults (294 complaints, 0.7% crash rate); Engine Problems (140 complaints, 0.7% crash rate); Wipers & Visibility (89 complaints, 0.0% crash rate). Crash percentages indicate how often that component failure resulted in an accident — higher percentages are safety-critical.
Which Hummer model years should I avoid?
Hummer models with the highest severity scores include Hummer H3 and Hummer H2. Specific model years to avoid depend on the model — click any Hummer model to see its year-by-year breakdown with complaint counts, crash rates, and recalls. Our AVOID label is applied when a year's normalized complaint rate exceeds 1.5× the model's median.
Which Hummer model is the most reliable?
Among Hummer models with at least 200 NHTSA complaints (enough data for a confident comparison), the lowest severity scores are: Hummer H2 (429 complaints), Hummer H3 (1,062 complaints). Lower complaint volume plus lower crash/fire/injury rates indicates fewer reported safety issues per vehicle on the road.
Is Hummer a reliable car brand?
NHTSA complaint data shows reliability varies significantly by model and year within every major brand — including Hummer. A brand-level reliability verdict is misleading because it averages a bad year of one model with a great year of another. VinItel's approach: pick your target Hummer model + year and view that specific page for actionable reliability data. See vinitel.com/stats/nhtsa-complaints/hummer to browse all 3 Hummer models.
Should I buy a used Hummer?
Buying used requires two checks: (1) research the specific model + year for known problems using the NHTSA data on this page, and (2) run a VIN report on the exact car to check for hidden accidents, title issues, and odometer rollbacks. VinItel offers both — reliability research is free, individual VIN reports are $4.99 (vs. Carfax $44.99). Common Hummer issues to ask about during inspection include electrical faults.
