Hummer Questions

After my daughter was forced off a road by a truck in to a snowy ditch, my 2008 (1 answer)

H3 Hummer wouldn't drive in regular drive, only 4 wheel drive. The mechanic said the transfer box was damaged internally and found the radiator was cracked after smelling fluid. Said it was probably from accident, but can't say for certain. Car was fine before accident. Landed in ditch at...

Safety hazard if the exhaust manifold is cracked? (1 answer)

Shouldn't this be a recall on GMS part as a safety issue? I have been told that a cracked manifold is a known issue with these 5 cylinder engines. Can it be welded? Would that be as expensive as a new replacement?

I have a loud squeak by my wheels (1 answer)

It squeeks/rattles when I drive,,,sometimes at an idle a little bit...but stops when I brake. It sounds like its coming from the front passenger side of the vehicle. But it seems to be getting louder. Then for stretches going down the road the noise just goes away. Make any sense to anyone?

Hummer Recalls

Heater And Air Conditioning Fan Speed Control Overheats

The connector module that controls the blower motor speed for the heating, ventilation and air conditioning system may overheat, causing a fire hazard. Dealers will replace part of the blower motor connector and harness free of charge to resolve the concern.

Possible Under Hood Electrical Fire

The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.

The Hood Louver Could Detach from the Vehicle

The retaining clips on the non-functional hood louver could brake. The louver could become loose and/or separate from the vehicle. If this were to happen while the vehicle is in motion, personal injury or property damage could result. Dealers will apply adhesive to the underside of the hood louver to secure it. The recall is scheduled to begin on April 12, 2010. The General Motors recall number is 10088.

Hummer Reviews

My visor was taken down in my 2007 H2 Hummer and will not stay up now. It seems to clip in, but when turned it will not stay latched. I have researched the diagram from this particular year and the years after and the design changed in 2008. The newer designs use screws to secure the visor (which makes much more sense to me). This leads me to believe that the design itself is flawed. Especiall...
