2005 Hummer H2 recalls
Seat belts: rear/other
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.
Fix: 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.
Full defect summary
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 improve the fit condition for this user group. In addition to instructions on proper infant and young child restraint (with child seats or boosters), special verbiage for restraining older child is included in the owner's manual. Also, the suggested seat belt fit/routing for adults, irrespective of seating position, is described in the owner's manual text.
Brakes: service brakes, hydraulic
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.
Fix: 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.
