Exactly what failed

NHTSA files every complaint against a named sub-assembly, not just a system. This is the difference between knowing it was "the engine" and knowing which part of it — the list to hand a mechanic.

Body 14 24.6%
Defroster/Defogger/Hvac System 10 17.5%
Sun/Moon Roof Assembly 7 12.3%

When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

Recalls on the 2006 Hummer H3

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

United States — NHTSA

15V421000

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:FAN/MOTOR

General Motors LLC (GM) is recalling certain model year 2006-2010 Hummer H3 vehicles manufactured February 5, 2005, to May 24, 2010, and 2009-2010 Hummer H3T vehicles manufactured May 21, 2008, to May 24, 2010. In the affected vehicles, the connector module that controls the blower motor speed for the heating, ventilation and air conditioning system may overheat.

Risk: If the blower motor connector module overheats, it can increase the risk of a fire.

10V179000

STRUCTURE:BODY:HOOD

GM IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 HUMMER H3 VEHICLES. SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH THE INTEGRAL CLIP-TABS ON THE LOUVER ON THE HOOD MAY FRACTURE, CAUSING THE HOOD LOUVER RATTLE AGAINST THE HOOD AND BECOME LOOSE. IF THIS INDICATOR IS UNNOTICED, ADDITIONAL CLIPS COULD FRACTURE AND THE HOOD LOUVER COULD DETACH FROM THE VEHICLE.

Risk: IF THE VEHICLE IS BEING DRIVING WHEN THIS OCCURS, IT COULD STRIKE A FOLLOWING VEHICLE AND CAUSE INJURY AND/OR PROPERTY DAMAGE.

06V417000

AIR BAGS:FRONTAL

CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.

Risk: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.

05V552000

EQUIPMENT:OTHER:LABELS

CERTAIN TRUCKS AND SPORT UTILITY VEHICLES FAIL TO CONFORM TO THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 110, "TIRE SELECTION AND RIMS." THESE VEHICLES WERE SHIPPED WITH TIRE AND LOADING INFORMATION LABELS LISTING AN INACCCURATE VEHICLE CAPACITY WEIGHT.

Risk: A MISPRINTED LABEL COULD LEAD TO IMPROPER VEHICLE LOADING SPECIFICATIONS OR TIRE INFLATION WHICH COULD RESULT IN A TIRE FAILURE, INCREASING THE RISK OF A CRASH.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2015286 5,189 units in Canada

Heater And Defroster

On certain vehicles, the connector module that controls the blower motor speed in the heat/vent/air conditioning (HVAC) system could overheat under extended periods at high or medium-high blower speed. If this were to occur, it could result in the plastic around the connector module melting by the heat generated, increasing the risk of fire resulting in injury and/or damage to property. Correction: Dealers will replace the female connector and harness.

Recall 2010140 5,196 units in Canada

Accessories

On certain vehicles, the integral clip-tabs on the hood louver may fracture, which could allow the hood louver to lose its retention mechanism. As the clip-tabs break, the hood louver may rattle against the hood and become loose. If this indicator is unnoticed, additional clips could fracture and the hood louver could detach from the vehicle and strike a vehicle or a bystander, which could result in property damage, personal injury or death. Correction: Dealers will apply an adhesive to the hood louver to secure it to the hood.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

ELECTRICAL SYSTEM

Theses templates dosent recognize the key and kicks on the security system which stops the motor from turning on. So you are stuck for 10 minutes then you can try again all so sometimes the motor tries to turn on by just sticking the key in the ignition before you even turn it. By looking at youtube alot of the H3s and the Colorados do this

POWER TRAIN

I was driving the vehicle at a normal rate of speed and stopped at a traffic light getting ready to change. I applied the brakes and when doing so, I heard some horrible noises and felt certain that parts had fallen out of the car. I knew something was immediately seriously wrong. I put the car in park (but it was effort and a grinding noise to put it in park) and stepped out to look under the car. No parts were on the ground, but something was leaking out of the bottom of the car. I got back in and put the car in drive to move it from the roadway knowing I was going to need assistance to tow it somewhere. It grinded trying to put it in any gear and only "revved" the engine when I tried to apply gas to drive it. There was absolutely no warning. The tow driver immediately noticed the drive shaft was disconnected and that was the leaking and thus going nowhere. My mechanic said that both leaf springs snapped off and that caused the drive shaft to sever, hitting the gas tank (or strap) and some other things. My concern is that there is a recall on leaf springs for every year Hummer H3 except mine as well as 1995-2015 Chevrolet, GMC, and Hummer leaf springs. I'm having a very difficult time with how both of mine snapped with no warning tearing all of these components out and it is not involved in the recall. It is the same parts on all of these. Also, my vehicle has spent the majority of its life garaged, never driven in the snow or rain, as I have babied this car. I have a car wash membership too and constantly keep this car meticulous. Hummer said that enough people need to complain, but I would not even have thought to complain had BOTH not snapped off simultaneously finding the recall for all other years while researching the cost. Had only 1 broke, I wouldn't have given it any thought. And Hummer said that they wouldn't even talk to me unless my car was at a GM dealership. This should be included in the recall. This is not pure coincidence. They need to fix it.
