2005 Chevrolet Avalanche recalls

4 NHTSA recall campaigns list this model year.

  1. NHTSA 06V289000Aug 3, 2006Engine38,439 vehicles

    Engine and engine cooling

    On certain trucks equipped with an 8.1l v8 (rpo l8-VIN g) engine have a condition in which the engine fuel rail pulse damper retainer clip may fracture resulting in inadequate retention of the damper.

    Risk: If the damper comes loose, a fuel leak may result. Fuel leakage, in the presence of an ignition source, could result in a fire.

    Remedy: Dealers will replace the engine fuel rail pulse damper retainer clip free of charge. The recall began on august 31, 2006. Owners may contact chevrolet at 1-800-630-2438 and gmc trucks at 1-866-996-9463.

  2. NHTSA 05V163000Apr 22, 2005Seat Belts1,359,824 vehicles

    Seat belts:rear/other

    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.

    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.

  3. NHTSA 05V055000Feb 14, 2005Transmission & Powertrain7,194 vehicles

    Power train:manual transmission:shift pattern indicator

    Certain sport utility vehicles equipped with an automatic transmission, fail to comply with the requirements of federal motor vehicle safety standard no. 102, "transmission shift lever sequence, starter interlock and transmission braking effect." under certain vehicle starting conditions, the shift lever position indicator located in the instrument panel cluster may not illuminate. If the shift lever position indicator does not illuminate, the driver may not know which gear the vehicle is in.

    Risk: The vehicle may move in an unintended direction resulting in possible injury to others outside of the vehicle.

    Remedy: Dealers will reprogram the instrument panel cluster free of charge. The recall began on february 14, 2005. Owners may contact cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438, and gmc at 1-866-996-9463.
