07- Brakes#2015372
241 units affected
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.
- Electrical#2014527
11,668 units affected
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.
- Lights And Instruments#2014146
5,990 units affected
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.
- Electrical#2014053
2,462 units affected
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.
- Lights And Instruments#2012300
1,168 units affected
On certain trucks, an electrical short circuit in the fog light circuitry could result in a loss of low beam headlamp function. Loss of headlamp illumination, should it occur during a rainy/snowy day, or during hours of darkness, could compromise the driver’s ability to see the road and its users, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will add an extra wiring harness between the cab harness and the Daytime Running Lamp (DRL) module, in order to isolate the fog light circuit.
- Other#2011261
76 units affected
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.
- Other#2011146
42 units affected
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.
