2008 Chevrolet Silverado 3500 HD RecallsFront Passenger Air Bag Defective

If too much current is drawn from the auxiliary battery, the fusible link can melt, causing risk of fire. Dealers will replace the jumper harness with one that includes a 40 amp inline fuse, and provide vehicle owners with supplemental owners manual information free of charge to resolve the problem.
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 recall is expected to begin on June 20, 2010.
