General Motors is expanding a previous recall concerning a faulty rear-axle cross pin to include another 26,751 SUVs and trucks from the 2011 model year. The first recall was issued in late December and concerned approximately 1,260 Cadillac Escalades, Chevrolet Avalanche and Silverado 1500s, and GMC Sierra 1500s, all from the 2011MY.
The updated recall now covers certain 2011MY Cadillac Escalade, Escalade ESV, Escalade EXT; Chevrolet Avalanche, Colorado, Silverado, Suburban, Tahoe; and GMC Canyon, Sierra, Yukon and Yukon XL vehicles.
The Detroit automaker said 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," said GM in a statement on NHTSA's website.
As expected, GM's dealers will install a new rear axle cross pin free of charge, with the safety recall to begin before the end of the month
