On certain vehicles equipped with Pre-Collision System (PCS), the system could unexpectedly activate while operating the vehicle. Under certain situations, the system may interpret a steel joint or plate in the roadway as an obstacle, and the system may apply the service brake automatically. If the PCS applies unexpected braking force during normal vehicle operation when no impending collision object is present, it could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will disable the Pre-Collision System (PCS) as an interim measure, and when parts become available, will replace the PCS components with improved parts.
Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard 135 - Brake Systems. If an ABS malfunction occurs during vehicle operation,the ABS warning lamp may fail to illuminate, contrary to the requirements of the standard. This could allow an ABS malfunction to go undetected by the driver, increasing the risk of a crash causing injury and/or property damage.
On certain cutaway chassis vehicles equipped with 6.8L engines and optional trailer brake controllers, during tow operation, the integrated trailer brake controller may not actuate the trailer brakes when the driver depresses the brake pedal. There would be no warning to the driver that vehicle braking does not actuate the trailer brakes, which could increase stopping distances, potentially resulting in a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the powertrain control module.
On certain motorcycles, the combined brake system's secondary master cylinder may cause the rear brakes to drag. Continued riding with the rear brake engaged/dragging may generate enough heat to cause the rear brake to catch fire. These issues could result in injury and/or property damage. Unexpected braking may also adversely affect vehicle stability, which could result in a crash.
Safety Risk
No risk description available.
Remedy
Dealers will replace the secondary master cylinder with one that has a modified check valve. In addition to replacing the secondary master cylinder, dealers will also replace the rear master cylinder and flush the brake fluid.
Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard 135 - Brake Systems and Canada Motor Vehicle Safety Standard 126 - Electronic Stability Control Systems. Due to a software error in the instrument cluster, Vehicle Stability Assist (VSA), ABS and BRAKE warning lamps may not illuminate under certain conditions, which fails to meet the requirements of the standard. Failure of these lights to illuminate could increase the risk of a crash causing injury and/or damage to property. Note: The warning light will illuminate with next key cycle.
Safety Risk
No risk description available.
Remedy
Dealers will update the instrument cluster software.
Certain vehicles may experience water wicking through the wire harness to the Anti-lock Brake System (ABS) module, which may disable the ABS and/or Electronic Stability Control (ESC) systems. Disabled ABS and/or ESC systems could increase the risk of a crash causing in injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will seal the ground eyelets with dual wall heat shrink, repair the wiring harness as required and replace the ABS Module as necessary.
On certain vehicles, the right parking brake cable may have been incorrectly installed resulting in insufficient clearance with the fuel tank, causing abrasive contact between the two components. This contact could result in the coating on the fuel tank deteriorating and allowing rust to form, which could result in fuel leakage. Fuel leakage, in the presence of an ignition source, could result in a fire causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the right parking brake cable and inspect the fuel tank. If the fuel tank’s exterior coating is damaged from contact with the parking brake cable, the fuel tank will also be replaced.
On certain vehicles, the draglink ball socket boot may be damaged due to the angle of the ball stud. This could cause contaminants to enter the ball socket and cause corrosion, accelerating the wear of the ball. If left untreated, the ball joint could separate from the socket resulting in complete loss of steering, increasing the risk of a crash causing injury and/or damage to property.
Certain vehicles equipped with a hinged left side rear door may have a condition where inadequate clearance between the rear brake lines and the lower fuel filler hose clamp may result in abrasion to one or both rear brake lines. This condition could cause brake fluid loss which could result in decreased brake line pressure, increased brake pedal travel and increased stopping distance, increasing the risk of a crash causing injury and/or damage to property. This condition could cause various warning lights to illuminate in the instrument panel of the vehicle such the red “BRAKE” telltale symbol; illumination of the Stabilitrak telltale symbol; scrolling display of “Service Brake”, “Service Stabilitrak,” and “Service Traction Control” messages in the Driver Information Centre (DIC); and audible alerts/chimes.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the brake lines. If the clearance is found to be below specification, the brake lines will be replaced with a new part design that provides adequate clearance.
Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard 135 - Brake Systems. During the manufacturing process, the parking brake controller assembly bracket may have been improperly formed. This could result in the pawl to not engage the sector gear during actuation and the parking brake not fully engaging. If the transmission is in Park, there will be no unintended vehicle movement. If the transmission is left in a gear other than Park, and the vehicle is parked on a sufficient slope, a non-functioning parking brake could result in unintended vehicle movement, increasing the risk of a crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will inspect, and if necessary, replace the parking brake control assembly.
Certain vehicles may have been manufactured with a defective Anti-Lock Braking System (ABS) actuator. This could cause pressure control to be delayed when the Anti-Lock Brakes are activated, resulting in loss of vehicle stability, increasing the risk of a crash causing in injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the ABS actuator and, if affected, replace the defective ABS actuator.
On certain vehicles, the bracket between the brake pedal assembly and the rod that actuates the vehicle service brakes may fracture. If this occurs, the vehicle service brakes will not function, which could increase the risk of a crash causing injury and/or damage to property. Note: The parking brake would continue to function properly.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the bracket and brake pedal, and replace if necessary.
Certain vehicles may have been manufactured with a defective Anti-Lock Braking System (ABS) actuator. This could cause oil pressure control to be delayed when the Anti-Lock Brakes are activated, resulting in loss of vehicle stability, increasing the risk of a crash causing in injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the ABS actuator and, if affected, replace the defective ABS actuator.
On certain vehicles, corrosion may occur in the ABS hydraulic unit due to a reaction between the brake fluid and the surface treatment of the internal valves. If this were to occur and the ABS hydraulic unit is activated, one or more of the valves could seize. This could result in longer brake pedal travel and increased stopping distances, which may increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will flush and clean the hydraulic unit by replacing the brake fluid with higher grade (DOT4) fluid. If module valve movement is determined to be poor, the ABS hydraulic unit will be replaced.
On certain vehicles, the Collision Mitigation Braking System (CMBS) could unexpectedly activate while operating the vehicle. In rare cases, the system may interpret certain roadside objects, such as metal fences or metal guardrails, as obstacles and apply emergency braking through the CMBS. If the CMBS applies unexpected emergency braking force during normal operation, it could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will update the vehicle sofware for the system.
On certain vehicles, the front brake calipers could leak brake fluid. This could cause longer brake pedal travel and increased stopping distances, increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect and if necessary replace the front brake calipers.
On certain vehicles equipped with a front center console cooled cubby box, a defect may exist in the antilock braking system, which could cause a fault to be registered in the system upon vehicle shutdown. This would cause the Dynamic Stability Control (DSC) warning light to be illuminated when the vehicle is restarted, and disable the DSC, traction control and hill descent control systems. The fault would also cause the air suspension to revert to its lowest setting, displaying a “Suspension Fault” warning on the instrument panel. These issues could increase the risk of a crash causing injury and/or damage to property.
On certain vehicles, originally sold, or currently registered in areas of heavy road salt usage during winter months (Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador), the front brake hose fitting at the caliper may corrode. If the fitting corrodes significantly, the internal brake hose-tube interface may develop a leak or in some cases break, causing a sudden increase in braking distances which may lead to a crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will replace both front brake hose assemblies.
On certain motorcycles, the rear brake line from the ABS pressure modulator to the foot brake cylinder may have been damaged during the assembly process or be subject to subsequent damage caused by vibration and contact with the spring clamp of the crank case ventilation hose. Damage to the rear brake line from the ABS pressure module could cause loss of rear brake function increasing stopping distance, resulting in a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the positioning of the crank case ventilation hose spring clamp and affect repairs.
On certain vehicles, brake chamber diaphragm(s) may not be properly seated. This could lead to brake drag, causing brake overheating or unintended spring brake application. These issues could increase the risk of a crash causing injury and/or property damage.
