General Motors (GM) is recalling certain model year 2012 Chevrolet Express and Suburban vehicles, and GMC savana and Yukon XL heavy duty vehicles. The steering gear pitman shaft may not have been adequately hardened and could fracture.
GM will notify owners, and dealers will inspect the steering gear and, if necessary, replace the steering gear pitman shaft. This service will be performed free of charge. The safety recall is expected to begin on April 4, 2012.
