This page combines three types of NHTSA data: recall campaigns (official manufacturer or government actions), owner complaints (unverified consumer reports), and crash test ratings (where available). A vehicle with many complaints is not necessarily less reliable — complaint volume correlates with sales volume and vehicle age. Recalls indicate identified defects, not overall quality. To compare this model year with others, use the year navigation in the sidebar or return to the model overview page.

Odometer Fraud. The contact purchased a 2007 Hummer H3. The contact discovered that there was a mileage discrepancy. The vehicle was an independent dealer sale. At the time of purchase, the vehicle mileage was 122,791 and at the time of registration, it was discovered that the mileage was 122,799 but additional documents also showed that the mileage was unchanged over a 3-year period.
The problem was unknown to me and probably would be to any vehicle owner that is not a mechanic. I was driving a death trap and didn't know how easily it could have been a serious problem. The driver side leaf spring bracket had completely broke apart from the frame on the upper drive side corner in an area that without getting underneath the vehicle with a flashlight and specifically looking for would be impossible to see. The only reason I know about it now is because I took it for an inspection and it failed due to this structural defect which the technician informed me was a very common issue with the 2007 H3 vehicles. He said that if I had been on a highway at 65/70 mph and this thing broke completely free the axle would swing out behind the vehicle on the drive side and cause an uncontrollable crash that could lead to severe injury and possibly death
Louver hood vent cover flew off on the highway as I was driving.
I have the well known issue with the passkey security system. Nothing is wrong mechanically with the car but the security system will not allow the truck to start, therefore leaving me randomly leaving me stranded. Much has been documented on this issue, yet gm has never done a recall.
So the part that is a malfunction is the rear doors weren’t made with any child lock and of course one of my kids opened the door while i was driving on the highway.I have a 3 and 5 year old and it scared me so bad I had to hurry and pull the hummer over and park and just held my son. I couldn’t even drive after that because of how bad it traumatized me. My mom had to come get and take me and my kids home and drive my hummer back home. Even though we didn’t crash or one of my kids didn’t fall out.it’s still a very serious safety hazard. I reached out to gm to see what my options were and there response was how gm made child locks in 2007 and up and that’s not the truth because mine is a 2007 and it clearly doesn’t have child locks. Then they later proceeded to tell me I should just sell my vehicle. I was so upset because if one of my kids would have fallen out and something happened I would do everything in my power to make sure they were held accountable and file a lawsuit against them. Yes The vehicle is available to inspect. My kids safety was at risk and then me braking and pulling off the highway in panic mode could have caused an accident.it’s been reported to gm and also local dealers. There was no warning just when it happened scared me so bad because my kids are in my back seat. The photos I uploaded are of the transcribed voicemails and I’m willing to also submit the voicemails from gm as well.

I bought my 2007 hummerh3 used w/124,000 miles. I've had it a month and already had it in mechanic shop due to not starting. The mechanic thought it was a fuel relay and charged me 258.00 parts/labor/tow. Today 11-16-21, only a day after I got it back, it stopped on me again!! Just had it towed again. Just learning that this is a common problem! Is anything being done to rectify this problem?
The (2) u-joints , upper and lower, in the steering column were failing and the front wheels would not return to straight. According to the shop that replaced the u-joints they had failed. This is the second H3 with the same problem.
Sunroof leaks & drain's don't work , my heart wiring plug has melted , do to water my car worning lights all were flashing then dash lights & speedometer all crashed and soon as I parked would not start. I took a dehumidifier put it in the shop and dried it out then everything worked again.

VEHICLE MISFIRES FREQUENTLY. ENGINE WILL NEARLY STALL AT IDLE DUE TO MISFIRES AND SHAKE THE WHOLE VEHICLE. LACK OF POWER AND EFFICIENCY. AND JUDDERING WHILE ACCELERATING. IT IS KNOWN TO GM AND MANY PEOPLE HAVE HAD TO RESORT TO CYLINDER HEAD REPLACEMENTS COSTING HUNDREDS AT A MINIMUM.
IGNITION SWITCH STAYS ON WITH KEY OFF AND OUT AND ALARM GOES OFF SOMETIMES JUST SITTING AND BATTERY GOES DEAD
OIL LIGHT COMES ON WHEN IDLE. TRUCK LOSES PRESSURE. NO DEALERSHIP SOLUTION.
WITH NO WARNING LIGHTS OR SIGNS, H3 WOULDN'T ACCELERATE WHILE PRESSING THE GAS.
TL* THE CONTACT OWNS A 2007 HUMMER H3. THE CONTACT STATED THAT WATER ENTERED THE VEHICLE FROM THE SUN ROOF ASSEMBLY. THE CONTACT STATED THAT WHILE VACUUMING WATER OUT OF THE VEHICLE, THE AIR BAGS IN THE VEHICLE DEPLOYED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC TO BE DIAGNOSED.

ON 3/13/2020 MY WIFE WAS DRIVING OUR 2007 HUMMER H3 WHEN THE ENGINE COMPARTMENT AND DASH AREA CAUGHT ON FIRE. THE BLOWER MOTOR CONNECTOR MODULE HAD BEEN REPLACED RECENTLY AS PART OF A SAFETY RECALL. THE VEHICLE WAS IN MOTION AND SHE HAD JUST MADE A LEFT TURN. ALTHOUGH THE PART HAD BEEN REPLACED, I STILL BELIEVE THAT THIS RECALL ISSUE WAS THE CAUSE OF SAID FIRE. THE FIRE DEPARTMENT CALLED IT AN ELECTRICAL ISSUE. THERE WAS NO WARNING AT ALL. THIS WAS TRAUMATIC FOR MY WIFE SHE HAD TO JUMP OUT OF THE VEHICLE AND HAD A MISCARRIAGE.
TL* THE CONTACT OWNS A 2007 HUMMER H3. WHILE DRIVING 35 MPH, THE ENGINE OIL INDICATOR ILLUMINATED AND AN ODOR EMITTED FROM THE VEHICLE.

WENT OUT TO START H3, TURNED KEY, CHECK ENGINE LIGHT CAME ON, THE BATTERY LIGHT CAME ON AND THE ANTI-THEFT SYSTEM LIGHT CAME ON. PASSLOCK/SECURITY SYSTEM INSIDE THE STEERING COLUMN IS BAD. CAR WON'T START. IS UNSAFE AND WILL STRAND OWNER WITHOUT WARNING BY NOT STARTING. GOES INTO SECURITY MODE. WAS TOLD TO WAIT 10 MIN AND TRY AGAIN. CAN'T TURN IT OFF AT GAS PUMP FOR FEAR OF IT LOCKING ME OUT AND NOT STARTING. I HAD THIS HAPPEN TO ME 4 TIMES IN ONE DAY. SO MANY COMPLAINTS ALL OVER THE INTERNET AND PEOPLE TRYING TO FIX THIS ISSUE. THERE IS EVEN A COMPANY SELLING A PART TO BYPASS THIS AND THE SECURITY SYSTEM WHICH AGAIN IS ANOTHER ISSUE. GM IS CLEARLY AWARE OF THIS ISSUE. THIS NEEDS TO BE RECALLED. STRANDING PEOPLE CAN BE VERY DANGEROUS. IF THERE IS AN EMERGENCY AND THE CAR WON'T START. ALL AROUND BAD BUSINESS BY GM FOR NOT ISSUING THIS RECALL. THIS HAS NOTHING TO DO WITH MILEAGE WHICH GM MANAGER SAID ON THE PHONE. THESE H3'S ARE KNOW FROM THIS FRESH OFF THE DEALERSHIP FLOOR. PEOPLE ARE BEING FORCED TO TAKE IT TO A DEALERSHIP FOR REPAIR AND REPLACING THE PART WHEN THE LABOR COSTS MORE THAN THE PART. SEEM LIKE A MONOPOLY FOR GM AND ITS DEALERSHIPS. I HAVE SEEN ANYWHERE FROM 1500-2000.00 TO INSTALL AND RECTIFY THIS BAD PART AT THE GM DEALERSHIPS.
DRIVING DOWN THE ROAD AND IT STOP AND IT WOULD NOT START ENGINE LOCK UP
THE TUBULAR FRAME HAD WHAT LOOKS LIKE COLD SLUGS WELDS AT SEVERAL JOINT LOCATIONS THAT ALLOWED WATER TO ENTER AND RUST FROM THE INSIDE OUT. THE FRAME CAN BE PUSHED THROUGH WITH A FINGER. THE FRAME SPRINGS BROKE WHILE DRIVING DOWN THE ROAD DROPPING THE FUEL TANK THROUGH THE GAS TANK CAUSING A FIRE HAZARD.
