This latest GM recall expands on an earlier one filed last year. The pin is in blue near the photo's center.
General Motors is recalling almost 27,000 pickup trucks and sport utility vehicles from the 2011 model year because the rear wheels can unexpectedly lock, possibly sending the trucks out of control and causing an accident.
Affected are Cadillac Escalade; Chevrolet Avalanche, Colorado, Silverado, Suburban and Tahoe, models; as well as GMC Canyon, Sierra and Yukon trucks. An improperly heat-treated part inside the rear axle differential can fail and jam the rear wheels.
GM did not specify where the defective part came from in its required defect filing with the National Highway Traffic Safety Administration.
This latest recall expands on an earlier one last year, NHTSA 10V-643, which only covered 1,200 vehicles at the time.
Dealers will install a new rear axle cross pin free of charge, as is required by U.S. law. The safety recall is expected to begin about January 25, 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. NHTSA campaign number: 11V-700
