GM has announced that they are recalling certain models of the 2012 Chevrolet Express and Suburban vehicles and GMC Savana and Yukon XL Heavy Duty vehicles. They stated that the steering gear pitman shaft may not of been adequately hardened and could fracture.
If this occurs, a loss of steering could result, increasing the risk of a crash. GM will notify owners and dealers will inspect the steering gear, and, if necessary, replace the steering gear pitman shaft. This service will be preformed free of charge. The recall will begin during April 2012.
