What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Hummer H1, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
THE BRIGHTNESS OF HEAD LAMPS ON BOTH SPORTS UTILITY VEHICLES AND MANY FOREIGN AUTOS IS A CONTINUOUS HAZARD. EVEN WHEN I'VE MOVED THE REAR VIEW MIRROR TO NIGHT SHADE, THE OUTSIDE MIRRORS BLIND ME. LARGE VEHICLES AWASH THE INTERIOR OF MY CAR AS IF I WERE SITTING IN FRONT OF A LANDING AIRPLANE. I REALIZE BY THE TIME ANYTHING IS DONE ABOUT THIS, I'LL BE DEAD BUT THOUGHT I THROW MY COMPLAINT IN HERE, ESPECIALLY ABOUT HUMMERS. *LA

From owner reports, verbatim
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
