Crash test ratings
NHTSA NCAP crash test ratings
New Car Assessment ProgramNCAP crash tests measure how well a vehicle protects occupants in controlled frontal crash, side crash, and rollover scenarios. Stars are awarded per category (5 = safest). These laboratory results are independent of owner complaints and are performed by NHTSA engineers on new production vehicles.
NCAP crash test ratings for this model are not yet loaded or this vehicle was not tested in the years analyzed. NHTSA tests a subset of new vehicles each year. Check nhtsa.gov/ratings directly for the latest results.

2002 HUMMER H1 HAS A DEFECT/FAILURE PROBLEM WITH THE AC DELCO ACCELERATOR PEDAL. *NJ THE CONSUMER STATED HE IS ON HIS THIRD PEDAL REPLACEMENT WITHIN 2 1/2 YEARS. THE CONSUMER STATED THE ISSUE WAS RAPID ACCELERATION WHILE DRIVING OR TRYING TO STOP.
I HAD TAKEN MY 2003 H2 HUMMER TO HAVE THE FRONT END ALIGNED AND 2 NEW TIRES PLACED ON THE FRONT . I COMPLAINED TO THE TIRE DEALERSHIP THE MOMENT I HAD DRIVEN MY VEHICLE MAYBE 10 MILES OF IT NOT DRIVING RIGHT . I TOOK MY VEHICLE BACK TO THE DEALER 3 TIMES WITH COMPLAINTS OF IT NOT DRIVING RIGHT. THINKING MAYBE THEY DID NOT TIGHTENED SOMETHING BACK UP WHEN THEY DID THE ALIGNMENT . I HAD ONLY DRIVEN MY VEHICLE APPROX. 5 TIMES (4 TIMES TO THE DEALERSHIP WITH COMPLAINTS)AND THE 5TH TIME I DROVE IT . I WAS IN AN ACCIDENT IN WHEN THE VEHICLE PULLED TO THE RIGHT I LOST ALL CONTROL AND MY VEHICLE WAS TOTALED . IT IS MY UNDERSTANDING THAT NITTO GRAPPER HAS RECALLED TIRES AND THIS WAS THE BRAND OF TIRES THAT WAS PUT ON MY VEHICLE . THE RIGHT FRONT TIRE WAS FLAT AFTER THE CRASH AN THIS IS ONE OF THE REASON THE TIRES ARE BEING RECALLED . I BELIEVE IT WAS EITHER THE TIRES OR THE ALIGNMENT NOT PROPERLY BEING DONE THAT CAUSED MY CRASH . *TR

The basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used Hummer H1, in plain English.
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The Hummer H1 has 5 complaints on record across 7 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The Hummer H1 has 1 recall campaign in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 1 of the Hummer H1's 5 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Excellent) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all Hummer H1 vehicles on the road — not any specific car. Two Hummer H1 vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The Hummer H1 has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
