Recalls
3 recalls name the 2005 Hummer H2. Newest first.
Certain fabtech aftermarket replacement pitman arms, p/nos. Fts71000 and fts71001, installed for use on certain 2001-2006 gm c/k 2500 pick up trucks and sport utility vehicles. the pin located inside the pitman arm can shear off due to a reverse bending fatigue condition, resulting in a total loss of steering control.
Risk and remedy
Risk
Loss of steering control could lead to a vehicle crash with potential injury or death.
Remedy
Fabtech will notify owners and replace the pitman and idler arms free of charge. the recall IS expected to begin during february 2006. owners may contact fabtech at 909-597-7800.
On certain crew cab pickup trucks and sport utility vehicles, the 2ND row center occupant seat belt routing may make it difficult to position the lap portion of the safety belt low around the hips of occupants, especially smaller occupants, seated in this position. appropriate use of a child seat or booster seat, as recommended for small children, does…
Risk and remedy
Risk
A lap portion of the seat belt routing that IS not low and snug on the hips can allow the lap belt to ride up on an occupant's abdomen instead of fitting low around their hipbones, and therefore, can expose them to more risk of abdominal and internal organ injury.
Remedy
Dealers will cut open the guide loop, remove a portion of the loop, and then the remaining two sides should be folded over and secured with a retainer free of charge. the recall began on july 21, 2005. owners may contact cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, or hummer at 1-800-732-5493.
Certain trucks, sport utility vehicles, and vans equipped with bosch hydro-boost brake assemblies, the hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.
Risk and remedy
Risk
If a separation occurred and the hood of the vehicle were open, fragments from the accumulator could cause injury to people in the immediate area. the presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. the loss of fluid would cause increased steering and braking effort and a crash may occur without prior warning.
Remedy
Dealers will test the hydro-boost assembly for functional operation of the two-function valve. if the hydro-boost assembly fails the test, dealers will replace the assembly free of charge. The recall began on march 23, 2005. owners may contact chevrolet at 1-800-630-2438, GMC trucks at 1-866-996-9463 and hummer at 1-800-732-5493.

Vehicle has 133,000 miles. it has now experienced an exhaust manifold gasket leak due to broken bolts. this IS causing noise from the engine area, and IS unsafe due to the leak of hot gases being released from the engine at the points of failure (broken bolts). this may be an epa concern as well, and could also lead to failure of catalytic converter. repair estimate IS $1,300. an online search yields hundreds of other results with same failure and complaint on all gm V8 engines for years 1999-2007. this affects the 4.8L, 5.3L, and 6.0L models. this IS a design failure and the affected vehicles with these engines should be recalled.

Takata recall hasn't included but should have included the H2 hummer 2005. This light IS on constantly. Feel very unsafe driving it. Now, because they are trying to say it's the consumers responsibility. I will take this matter to the news stations if I have to. That's totally ridiculous. The vehicle was parked and when we got into it to leave the light was on and blinking and would not go off.

The sdm (sensing and diagnostic module) on my 2005 hummer H2 IS not working and IS causing my air bags to not work, and also causes other modules to not be able to communicate and cause my gauges and other electrical accessories to not operate (windows, locks, etc.) many other hummer H2 owners are having this same problem. a new sdm would fix the issue, but gm for some reason has discontinued manufacturing this module. why would gm stop making a safety related item for vehicles that are only arould 10 years old with many still on the road. so, now we must drive it with the air bags most likely not going to deploy in a crash.

A problem with nearly all hummer H2S IS roof leak, there IS a drainage system to drain the water thru the vehicle. This clogs up periodically and the water drains into the vehicle and ends up on the front floorboard. the airbag sensor diagnostic module IS mounted on the floorboard directly under the drivers seat. If this gets wet, which it does, the module IS ruined and renders the airbags inoperable. This has happened to my vehicle and I am sure many others. If this module IS not in working order it has to be replaced, however, general motors has discontinued making the airbag sensor diagnostic module for the 2005 hummer H2 model year!. I am sure I am not the only person (owner) caught up in this situation. The vehicle IS still operative and drivable. Airbag sensor diagnostic module should be available and manufacture should ensure it IS available. the vehicle IS only 10 years old and if I owned a prior year the module IS still available. It IS a safety issue because of where it IS located in the vehicle and manufacture knowledge of leak problems, and only one year discontinued. I have contacted general motors and there reply was "sorry". It very apparent general motors has no regard for the safety of their customers!

Odi upgraded this investigation at the conclusion of pe04-080.the alleged defect involves the failure of the steering knuckle at the lower ball joint boss, resulting in a separation of the lower ball joint from the knuckle.a lower ball joint separation could result in a loss of steering and/or a disabled vehicle. It appears that the fractures of H2 steering knuckles can be attributed to wheel/tire collision forces being transferred directly to the steering knuckle.the original knuckle design appears to be sufficient for the H2 application.evidence from inspected vehicles, photographs, police reports and edr data indicates collision impact events placed stress on the steering knuckle causing it to fracture.further use of agency resources does not appear to be warranted.the closing of this investigation does not constitute a finding by nhtsa that no safety-related defect exists with regard to the subject component.the agency reserves the right to take further action on this issue if warranted.
