2011 Mack Cxu Recall

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.

A failure of this component (brakes) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

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.

A failure of this component (accessories) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

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.

A failure of this component (electrical) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

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.

A failure of this component (lights and instruments) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

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.

On certain trucks equipped with Bendix ATR-6 Antilock Traction Relay valves, in extremely cold conditions (at or below -18 degrees Celsius), internal ATR valve leakage can occur. This could cause unintended brake application, which could overheat the affected brakes and cause a fire. Also, in certain low traction conditions, unexpected brake application can cause a loss of vehicle control and a crash. These issues could result in property damage and/or personal injury. Correction: Dealers will update the cover assembly on the ATR valves.

A failure of this component (brakes) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain trucks, the clutch pedal assembly may have been manufactured incorrectly and could fail. This could allow the clutch pedal to fall to the floor, prohibiting clutch operation, and causing a reduction in braking efficiency. Increased stopping distances could result in a crash causing property damage and/or personal injury. Correction: Dealers will replace the clutch pedal assembly.

A failure of this component (other) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain vehicles, the slack adjuster housings may have been manufactured incorrectly, which could allow the housings to fracture and fail. As a result, the wheel brake to which the slack adjuster is attached would no longer function, which could increase vehicle stopping distances. Should a steer axle slack adjuster fail, it could also cause the vehicle to pull to one side during braking. Either problem could result in a crash causing property damage and/or personal injury. Correction: Dealers will inspect and, if necessary, replace the slack adjusters.

A failure of this component (brakes) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain trucks, the bolts used to secure the fifth wheel hitch assembly to the frame may not have received adequate tightening torque during vehicle assembly. This could allow the mounting bolts to fail and the fifth wheel assembly, as well as the trailer, to separate from the tractor. A towed unit separating from the towing vehicle could strike another vehicle, stationary object, or bystander, causing property damage and/or personal injury. Correction: Dealers will inspect the mounting bolts and replace as required.

A failure of this component (other) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain trucks, the rear hold-down brackets that secure the battery box lid may be rotated too far forward, which may restrict the battery box lid from properly locking into place. If this occurs, the battery box lid may come off when stepping on the step, which may cause a person to fall from the vehicle resulting in personal injury. Correction: Dealers will inspect and adjust the rear hold-down brackets as required.

A failure of this component (other) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

On certain vehicles, the rear conspicuity reflector typically found on the mud flap hanger brackets may not have been installed in the back of the cab which is the alternate position allowed for vehicle manufactured without mud flap hanger brackets. Missing reflector is a non-compliance with Canada Motor Vehicle Safety Standards 108 - Ligthing System and Retroreflective Devices. Correction: Dealers will inspect and if missing will install the required reflectors.

A failure of this component (visual system) may increase the risk of a crash or injury.
