GM is expanding a recall of some 2011 trucks and SUVs, including the 2011 Chevrolet Colorado and GMC Canyon, to fix a problem that could cause the vehicle’s rear axles to lock.  The recall now includes 26,751 vehicles.  GM is telling owners not to drive the vehicles until the axle pin is replaced.
The recall, which was originally announced in December and covered 1,262 U.S. vehicles, now includes 26,751 vehicles. They include the 2011 Cadillac Escalade, Cadillac Escalade ESV 1500, Cadillac Escalade EXT 1500, Chevrolet Avalanche 1500, Chevrolet Colorado, Chevrolet Silverado 1500, Chevrolet Suburban 1500, Chevrolet Tahoe, GMC Canyon, GMC Sierra 1500, GMC Yukon and GMC Yukon XL 1500.
“The rear axle cross pins were not properly heat treated and could fracture and become displaced within the rear axle,” said the National Highway Traffic Safety Administration in its recalls summary of the problem. “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.”
GM dealers will install a new rear axle cross pin. The recall is expected to begin by January 25.
