2004 GMC Sierra 2500 RecallsFuel May Leak from Fuel Rail
The retainer clip for the fuel rail pulse damper may fracture and allow the damper to come loose from the fuel rail. A fuel leak in the presence of an ignition source may result in a fire. Dealers will replace the engine fuel rail pulse damper free of charge. The recall began August 31, 2006. The GM recall number is 06080.
The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.
