Issue: On certain trucks, the front turn signals may not be visible from certain angles. As a result, the trucks don't meet the requirements of the Canadian regulations. Safety Risk: Turn signals that aren't visible from certain angles may cause a person not to recognize when a driver intends to turn or change lanes. This could increase the risk of a crash. Corrective Actions: Mack will notify owners by mail and advise you to take your truck to a dealership to install additional front turn signals.
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 outfitted with an Automatic Over-Speed Protection system, the system may be incorrectly wired. This presents a potential risk as the operator may not be able to control an unintended increase in the engine RPM if combustible vapors enter through the air intake. If this occurs, it could increase the risk of an engine fire that may cause injury and/or property damage. Correction: Dealers will inspect and repair accordingly.
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 equipped with Cummins ISL engines, the fuel filter shell and nut plate could separate, causing a fuel leak and also causing the engine to stall. Stalling would result in a loss of motive power, increasing the risk of a crash resulting in injury and/or damage to property. Correction: Cummins-authorized dealers will replace the fuel filter.
On certain vehicles, bolts securing the seat belts to the seat frame, cab wall and cab floor may have been insufficiently tightened during vehicle assembly. As a result, bolts could loosen over time and potentially allow the seat belt to detach from its mounting points. If this occurs, the seat belt may fail to restrain the seat occupant in a crash, increasing the risk of injury and/or damage to property. Correction: Dealers will tighten the affected bolts to the specified torque.
