GMC Sierra 3500 Recalls

Front Passenger Air Bag Defective

In a crash that deploys the passenger front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front passenger air bag inflator free of charge to correct the concern.

Auxiliary Battery Fuse Link Melts

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.

Possible Under Hood Electrical Fire

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 previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.
