The manufacturer was made aware of the problem. The approximate failure mileage was 112,000.

Blower motor recall issue. Burning electrical odor coming from behind the glove compartment. Coincides with the blower motor connector recall. This cannot be resolved soon enough.

This will be the third blower motor resistor that I have had to replace. This time I am replacing the harness because it burned up so badly on two terminals. Gm has yet to acknowledge this problem... I paid $26 for the resistor, and it's going to be $30 for the harness, and I save a ton on the labor because I am a mechanic, but this is a potential fire hazard. There is an air flow in this area, and can fan or start flames in this area if it occurs while driving. Very dangerous! This is my second report. *tr

Pass lock system prohibits truck from starting. Have to wait 10 minutes when it decides to work. This is an ongoing issue. For the amount of money this truck cost this should not be happening consistently.

11/02/11 smell of something burning looked under dash blower resistor and plug melted together had replaced on 12/11/11 smelt burning plastic again had same problem blower resistor and plug melted again from what I understand it is a on going problem in this vehicle gm should be responsible in fixing it before there are major fire damage or a death. *tr

Tl* the contact owns a 2006 Hummer h3. The contact stated that while driving approximately 55 MPH, there was a reduction in the engine power as the rpms decreased. The vehicle began to vibrate violently. The vehicle was taken to the dealer on three separate occasions. The mechanic replaced the head gasket and engine coil twice. The manufacturer was notified of the failure. The approximate failure mileage was 30,000.

On several occasions the engine has loss power in traffic and slows down to 15 miles an hour. Once on the highway causing other cars to swerve to avoid rear ending us. Another in rural traffic causing other cars to go around. We are always leary when driving this vehicle. Our mechanic has looked it over on both occasions and can not find anything wrong and we have the best mechanic in town. Gm should pay a little now and recall this vehicle and fix what's wrong instead of a lot later when someone's family is killed. I bought this car for my wife to transport our grandchildren to school and after school events every time she gets in that thing I worry but because I bought it for her she is reluctant to sell. Gm please fix. *tr

My vehicle has a cracked radiator and according to other Hummer owners this is a common defect that happens to these vehicles. *tr

Tl*the contact owns a 2006 Hummer h3. While idling at a stop light, the accelerator pedal automatically extended to the floor and the vehicle sped forward. The contact had to depress the brake pedal with both feet to prevent crashing into the preceding vehicle. The vehicle then went into limp mode and would not exceed 20 MPH. The vehicle was towed to the dealer and they replaced the throttle body assembly. The dealer stated that this was a common failure with these vehicles caused by a manufacturer defect. General motors acknowledged the failure and stated that they were replacing the unit with a different part that they believed would eliminate the failure. The replacement would be at the contact's expense. The manufacturer stated that they have not considered issuing a recall bec

HVAC system fan blower works intermittently...sometimes the fan blower doesn't work or stops working altogether causing a major problems on cold or foggy days when you need the defrost to work. Reported this to gm dealer but no repairs made. *tr

Was driving this vehicle about 45 mph and began to shake violently. Was able to get it slowed down and back under control. Happened two more times on my drive home and took it to an auto repair shop today and found the frame is broken on both sides in front of rear leaf springs.

When the car is idling, there is a strong smell of exhaust fumes coming out of the air vents. The smell dissipates when the car is in motion. The vehicle has been checked for any leaky exhaust pipes or gaskets but nothing has turned up positive.

Passenger side air bag sensor problem. Air bag will not inflate upon inoact. Warning light on all the time

Sunroof drains leaked and saturated the carpet. Removed the carpet and found seatbelt anchors very corroded. (see photo) this condition appears to be from water collecting in the anchor attachment area.
