Mack Cxu-pinnacle 2013

• Recall 2016642 [Canada]: Steering
  On certain vehicles, the front hubs do not support the gross axle weight rating of the front axle. Specifically, 5,987 kg (13,200 lbs.) rated front hubs were used on trucks requiring a 6,622 kg (14,600 lbs.) rated front axle. If the axle load exceeds the maximum weight capacity of the hub, there is an increased risk of hub and bearing failure, which could cause a complete separation of the wheel(s) and a loss of vehicle control, increasing the risk of a crash causing injury and/or damage to property. Correction: dealers will replace the front hub assemblies with hub assemblies rated for 6,622 kg (14,600 lbs). Note: if damage occurs due to overloading, the abs malfunction light may illuminate as the distance between the abs tone ring and the sensor increases (i.E. Sensor loses contact with the tone ring).

• Recall 2016495 [Canada]: Powertrain
  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.

• Recall 2016320 [Canada]: Powertrain
  On certain vehicles, the front axle beam may have been improperly heat treated, affecting material properties. This could lead to fracture of the axle beam at the kingpin, potentially causing lead to a loss of vehicle control and a vehicle crash causing injury and/or damage to property. Correction: dealers will inspect the axle beam for batch code and serial number markings and replace affected axles. Note: there may be evidence of the beam deforming before the knuckle and king pin loosens from the beam.

• Recall 2016079 [Canada]: Powertrain
  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.

• Recall 2015457 [Canada]: Structure
  On certain vehicles, the fifth wheel locking mechanisms could be susceptible to damage and/or wear. This could cause the locking mechanism to fail properly engage, potentially resulting in a towed trailer unit separating from the truck tractor. As a result, the trailer could strike another vehicle, stationary object, or bystander, causing injury and/or damage to property. Correction: fontaine dealers will replace all ultra lt fifth wheel units with ultra nt model fifth wheel units.

• Recall 2015372 [Canada]: Brakes
  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.

• Recall 2015100 [Canada]: Accessories
  On certain vehicles, the fifth wheel remote unlocking switch may not work as designed. As a result, the driver may inadvertently release the 5th wheel latch when the park brake is applied if he/she presses or bumps the switch. This could cause the trailer to decouple from the truck increasing the risk of injury and/or damage to property. Correction: dealers will add a redundant measure such as an additional switch or adding a thumb lock that requires 2 actions to push the switch.

• Recall 2014527 [Canada]: Electrical
  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.

• Recall 2014147 [Canada]: Lights and instruments
  Certain vehicles may not comply with the requirements of canada motor vehicle safety standard 108 - lighting system and retroreflective devices. Conspicuity tape applied to the back of the cab may be obscured by exhaust system components to a greater degree than what is allowed by the standard. This could reduce vehicle conspicuity during hours of darkness, potentially increasing the risk of a crash causing injury and/or damage to property. Correction: dealers will add reflectors if necessary.

• Recall 2014146 [Canada]: Lights and instruments
  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.

• Recall 2013346 [Canada]: Powertrain
  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.

  Show Content

• Recall 2013161 [Canada]: Brakes
  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.

  Show Content

• Recall 2012346 [Canada]: Wheels
  On certain vehicles, the wheel rims may have been manufactured incorrectly and could fail. A wheel separating from the vehicle could cause a loss of control and a crash. In addition, the errant wheel assembly could strike a vehicle, stationary object, or a bystander. These issues could result in property damage and/or personal injury. Correction: dealers will inspect and, if necessary, replace the wheel rims. Note: further evaluation revealed that no canadian vehicles are involved.

• Mdrive transmission failure to disengage investigation # PE20005

  In a review of field reports submitted under early warning reporting (ewr) 49cfr 579.22(c), over several years by mack trucks, the office of defects investigation (odi) identified a trend of drivers who complained that their transmissions failed to disengage from gear while slowing the vehicle. This failure to disengage resulted in the truck wanting to pull through the service brakes when coming to a stop. Affected trucks are equipped with an mdrive automated manual transmissions. The repair has involved the replacement and/or adjustment of the service brake switch.Odi previously investigated (pe13-268) a similar concern on 2007-2012 volvo trucks equipped with an i-shift automated manual transmission in which the clutch would not automatically disengage as intended. The investigation resulted in volvo releasing safety recall 13v-268.Both volvo i-shift and mack mdrive transmissions share similar configurations in their design and function. Mack is a subsidiary of ab volvo who also manufacture volvo trucks.This preliminary evaluation is opened to examine the alleged defect in all affected vehicles.The odi report cited above can be reviewed at: http://www-odi.Nhtsa.Dot.Gov/owners/searchnhtsaid using the following complaint identification number: 10839430
