On certain vehicles, the cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may prematurely loosen. If the nut were to loosen and come off, the yoke could separate from the axle input shaft and cause the drive shaft to disconnect. A disconnected drive shaft would result in a loss of motive power, and create a road hazard, both of which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect the torque on the cap nut, and the nut will be replaced if the torque is found under specification. Note: This is an expansion of recall 2016-079.
On certain vehicles, the cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may prematurely loosen. If the nut were to loosen and come off, the yoke could separate from the axle input shaft and cause the drive shaft to disconnect. A disconnected drive shaft would result in a loss of motive power, and create a road hazard, both of which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the cap nut, and inspect the threads on the input shaft. If the threads are damaged, the input shaft will be replaced.
On certain vehicles, The chassis electrical harness and air brake lines may not have been properly secured at the crossmember. This could cause the electrical cables and air lines to fall down and get twisted in the driveline. This could affect safety systems such as brakes, increasing stopping distances or causing unintended parking brake application. This could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect and repair the vehicle as needed.
On certain model vehicles, water around the windshield can migrate into the Electronic Power Distribution Module and contaminate it. As a result, circuits may be bridged creating an electrical short. This could potentially result in a fire, increasing the risk of injury and/or damage to property. Correction: Dealers will inspect the module, and if found contaminated, will replace it. Additional measures will be taken to address the leak if contamination is found. Note: This is an expansion of recall 2014-053.
On certain vehicles, the directional/hazard signal flasher may fail. Actuation of the turn signal or hazard lights in this condition would cause them to remain illuminated and not flash as intended. As a result, drivers may not be able to clearly signal their intentions to turn, change lanes or warn others in an emergency situation. Correction: Dealers will replace the turn signal/hazard flasher module.
On certain model vehicles outfitted with an Automatic Over-Speed Protection system, the system may be incorrectly wired. This presents a potential risk in applications where the Power Take-Off system is engaged, which could result in injury and/or property damage. Correction: Dealers will rewire the system.
On certain vehicles, the tie rod end clamp bolts may not have been torqued to specification. As a result, the tie rod ends could separate from the tie rod, resulting in a loss of steering control, increasing the risk of a crash causing injury and/or damage to property. Correction: Dealers will inspect repair vehicles as required.
On certain vehicles, spindle nuts may have been installed incorrectly and could loosen, possibly resulting in the hub, wheel and tire assembly separating from the vehicle. This could increase the risk of a crash causing injury and/or property damage. Also, should a wheel separate from the vehicle, it could pose a danger to nearby motorists or bystanders, which could result in injury and/or property damage. Correction: Dealers will inspect and repair vehicles as required.
On certain trucks, the cotter pin which retains the brake slack adjuster’s clevis pin may have been omitted during vehicle assembly. As a result, the clevis pin could loosen and fall out, causing a loss of brake function at the affected wheel. This could cause the vehicle to pull to one side under braking, or increase stopping distance, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will verify cotter pin installation on each brake slack adjuster. Replacement cotter pins and/or clevis pins will be installed as needed.
