On certain vehicles operated in areas of heavy road salt usage, excessive corrosion of the rear cross member may cause separation of the spare tire stowed under the truck bed. Corrosion of the rear cross member may also affect the functionality of the rear brake line at the proportioning valve. A spare tire that separates during vehicle usage could impact nearby persons or objects resulting in personal injury and/or vehicle and property damage. Correction: Dealers will inspect the rear cross member and surrounding components and, depending on the amount of corrosion detected, either apply a corrosion-resistant compound or replace the cross member assembly.
On certain vehicles, a manufacturing issue with the front lower ball joint could result in premature wear. If the vehicle is operated for an extended period of time in this condition, the ball joint may eventually experience excessive wear and looseness, resulting in increased steering effort, reduced vehicle self-centering and noise in the front suspension. In extreme cases, when the driver continues to operate the vehicle in this condition, the lower ball joint may separate from the knuckle causing a loss of vehicle steering control. Correction: Dealers will inspect and, if necessary, replace the front lower ball joints.
