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.

THE OTHER DAY I TOOK A RIDE IN MY TRUCK AND UPON DRIVING APPROXIMATELY TWO BLOCKS FROM MY HOME THE STEERING CONTROL OF THE CAR TOTALLY FAILED. IMAGINE DRIVING YOUR CAR AND AT SOME POINT, YOU LOSE THE CAPABILITY OF CONTROLLING YOUR CARS DIRECTION WHILE HOLDING YOUR STEERING WHEEL. ONE CAN ONLY IMAGINE IF I WAS GOING 65 MILES AN HOUR AND DRIVING ON A HIGHWAY THEN LOSING THE ABILITY TO TURN YOUR WHEELS. I AM BLESSED THIS MALFUNCTION HAPPENED WHEN I WAS ONLY TRAVELING 10 MILES AN HOUR. AFTER CALLING A TOW TRUCK AND HAVING MY CAR TOWED TO A LOCAL REPAIR SHOP, IT WAS DETERMINED THE CONTROL ARM BOLT HAD BROKEN OFF THEREFORE LOSING TOTAL CONTROL OF THE CARS STEERING CAPABILITY. THIS IS UNHEARD OF AND SOMETHING LIKE THIS SHOULD NEVER HAPPEN AT ALL DURING NORMAL USE. WITH ALL OF THIS I CONTINUE TO THINK ABOUT HOW LUCKY I WAS TO SURVIVE A MECHANICAL PROBLEM OF THIS SORT AND HOW I COULD HAVE FATALLY INJURED SOMEONE ELSE WITH THIS DEFECTED CONTROL ARM OF THIS VEHICLE. SO, I DECIDED TO MAKE A CALL TO GM AND REPORT THIS ISSUE AND TO ADVISE THE COMPANY OF A PROBLEMATIC ISSUE WITH THE DESIGN OR ENGINEERING OF THE HUMMERS CONTROL ARM STEERING COMPONENT THE COMPANY REPRESENTATIVE ACKNOWLEDGED MY COMPLAINT AND RECORDED MY DESCRIPTION OF THE EVENTS AND THE ISSUES OF THE CARS STEERING SYSTEM. I REITERATED MY CONCERNS ABOUT THE ISSUES AND HOW NOT ADDRESSING THIS IN SOME SORT OF A RECALL MAY RESULT IN DEATHS. I AM ATTACHING PICTURES OF THE PART WHICH THE BOLT HAD BROKEN SO YOU MAY CONSIDER A RECALL OF THE VEHICLE'S CONTROL ARM. I GUESS PEOPLE NEED TO GET HURT BEFORE YOUR COMPANY ACTS AND TAKES THIS SERIOUSLY.

VEHICLE INTERIOR CAUGHT FIRE AT THE BASE OF THE TOP SITTING AREA OF THE REAR SEAT, FLAMES FROM FIRE MELTED THE OVER HEAD INTERIOR LIGHT AND IGNITED A FIRE ON THE HEAD LINER, WHICH CAUSED THE FIRE TO SPREAD UNDER NEATH THE HEADLINER AND ROOF OF THE VEHICLE, MELTING THE EXTERIOR PAINT. THERE WAS NO PRIOR INDICATION OF BURNING WHEN DRIVING OR AFTER PARKING THE VEHICLE PRIOR TO THE FIRE. FIRE DEPARTMENT ADVISED IT WAS BELIEVED TO BE RELATED TO REAR SEAT HEATERS MALFUNCTIONING CAUSING COMBUSTION THAT LEAD TO AN INTERIOR FIRE.

AT FIRST THE WASHERS JUST KEPT SPRAYING AND WOULDN'T STOP. I HAD TO TAKE OUT THE FUSE TO GET IT TO STOP. I RECENTLY PUT THE FUSE BACK IN AND NOW IT WON'T WORK. THE WASHERS WILL JUST START SPRAYING OUT OF THE BLUE AND THIS IS VERY DANGEROUS IF YOU ARE DRIVING DOWN THE ROAD AND YOU CAN'T GET IT TO STOP. IT DECREASES YOUR VISIBILITY. I HAVE READ THAT THEY HAVE HAD RECALLS ON THIS ISSUE. IT SOUNDS LIKE THEY HAVE ALOT OF ELECTRICAL ISSUES. ALSO THE HEATING UNIT ON MY DRIVER SEAT RANDOMLY COMES ON BY ITSELF AND WON'T SHUT OFF. I BOUGHT THIS HUMMER USED AND NEVER HAD ANY ISSUES UNTIL RECENTLY. I HAVEN'T RECEIVED ANY RECALL NOTICES BUT I WONDER IF I SHOULD OF. THIS IS DANGEROUS ISSUES. *TR
HEAVY FUMES ARE PRESENT INSIDE AND OUTSIDE THE VEHICLE AFTER THE FUEL TANK IS FILLED AND PERSISTS UNTIL THE FUEL GAUGE READS 7/8 OF A TANK.

STEERING IS VERY SLOPPY AND VAGUE AT HIGHER SPEEDS. THERE IS TOO MUCH NON ACTIVE MOVEMENT TO CORRECT DIRECTION. I HAVE TO MOVE THE STEERING WHEEL AT LEAST 6 INCHES CONSTANTLY TO EVEN KEEP THE TRUCK STRAIGHT. I HEAR GM HAS WEAK PITMAN ARMS ETC.. ALSO THE STEERING JUDDERS AND VIBRATES AND SOMETIMES IT GETS STUCK AND GOES WHEN COLDER USUALLY. SOMETIMES BRAKES ARE STRONG, SOMETIMES THEY ARE WOODEN AND LACK GRIP ALMOST RESULTING IN AN ACCIDENT. I KEEP MUCH DISTANCE TO THE OTHER CARS SO I DID NOT CRASH. BUT I GET A SCARED SENSATION WHEN CONTROLS DON'T WORK CORRECTLY. *TR
I PURCHASED A 2006 HUMMER H2 AT CERRITOS HUMMER. I CURRENTLY HAVE ALMOST 55,000 MILES. TODAY I WAS PARKING MY CAR AND NOTICED THE STEERING WAS EXTREMELY HARD TO TURN. ALSO THE BRAKES WERE REALLY WEAK. I USED ALL THE ENERGY I HAD TO GET INTO A GAS STATION DRIVEWAY. I DROVE ABOUT 1 BLOCK BECAUSE I NEEDED GAS WHERE I NOTICED OIL DROPPING UNDER THE CAR. I CHECKED UNDER THE HOOD AND THE OIL WAS COMING OUT NEAR THE POWER STEERING PUMP. I OPENED THE POWER STEERING RESERVOIR AND SAW THAT THERE WAS VERY LITTLE OIL BECAUSE IT HAD DROPPED UNDER MY CAR. MY STEERING IS TOO HARD TO TURN AND THE BRAKES ARE ALMOST NON EXISTENT PULLING INTO THE GAS STATION. I CALLED CERRITOS HUMMER AND TALKED TO THEIR SERVICE MANAGER AND HE SAID I WAS PAST WARRANTY. I TOLD HIM THAT THERE WAS A RECALL ON THIS EXACT PROBLEM, BUT HE SAID NO AND GOT VERY LOUD AND MEAN TO ME. I TOLD HIM HE DID NOT HAVE TO GET MEAN BECAUSE HE CAN ONLY DO WHAT THE COMPUTERS AND PROTOCOL SUGGESTS, BUT HE DID NOT DO ENOUGH RESEARCH PRIOR TO REJECTING ANY RECALLS. HE SAID I WOULD HAVE TO TOW MY CAR THERE AND THEY WOULD HAVE TO INSPECT AND THE CHARGES COULD BE HIGH DEPENDING ON THE PROBLEM. I SAID THERE WAS A RECALL BUT HE REJECTED IT AGAIN IN A STRONG TONE. I DID NOT WANT TO ARGUE IN CASE THEY HAVE TO REPAIR MY CAR. I THINK THAT THIS PROBLEM IS A SERIOUS HEALTH ISSUE BECAUSE A WEAK PERSON WOULD NOT HAVE THE STRENGTH TO PULL INTO THE PARKING LOT AS I DID. I PULLED VARIOUS MUSCLES IN MY ARMS AND SHOULDERS STEERING THE CAR INTO THE GAS STATION. I DO NOT HAVE ANOTHER CAR AND I DON'T THINK I CAN PAY THE COST TO HAVE MY CAR TOWED APPROXIMATELY 25 MILES TO CERRITOS HUMMER. THEY SAID THEY WOULD NOT PAY ANY TOW CHARGES NOR INSPECTION COSTS NOR COSTS TO REPAIR THE PROBLEM. I SPEND WAY TOO MUCH MONEY AT THEIR DEALERSHIP TO BE TREATED THIS WAY. I AM USUALLY AN EASY GOING GUY, BUT THE TREATMENT HE GAVE ME REALLY ANGERED ME. MY BACK ARMS AND SHOULDERS HURT BECAUSE THE STEERING WAS SO HARD. *TR

The basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used Hummer H2, 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 H2 has 356 complaints on record across 9 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 H2 has 23 recall campaigns 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. 25 of the Hummer H2's 356 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 (Poor) 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 H2 vehicles on the road — not any specific car. Two Hummer H2 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 H2 has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
