General Motors has expanded an earlier recall from last month over a potential problem with the rear axle/suspension, according to the National Highway Traffic Safety Administration.
Affected models include the 2011 Cadillac Escalade, Escalade ESV and Escalade EXT; Chevrolet Avalanche, Colorado, Silverado, Suburban and Tahoe; and GMC Canyon, Sierra, Yukon and Yukon XL. While the initial recall affected only 1,262 vehicles (and all the vehicles were trucks), now 26,751 vehicles (including SUVs) are affected.
In the affected vehicles, the rear axle cross pin was not manufactured correctly. As a result, the pin could fracture and become displaced within the rear axle, causing the axle to lock up. This condition could make maintaining direction control difficult, increasing the likelihood of an accident without prior warning.
GM is expected to begin the recall Jan. 25. Dealerships will install a new rear axle cross pin free of charge on affected vehicles.
