GM has announced that they are recalling certain models of the 2011 Cadillac Escalade EXT, Chevrolet Avalanche, Silverado LD and GMC Sierra LD vehicles.  They stated that the rear axle cross pins were not properly heat treated and could fracture and become displaced within the rear axle.  Should the pin shift out of position, it could create an interference condition and cause the rear axle to lock.

The driver may not be able to maintain directional control of the vehicle and a crash could occur without warning.   Dealers will install a new rear axle pin free of charge.  The recall is expected to begin during January 2011.  Owners may contact Cadillac at 1-866-982-2339, Chevrolet at 1-800-630-2438, GMC at 1-866-996-9463 and at the owner center at www.gmownercenter.com.
