Certain vehicles equipped with Intelligent Cruise Control may have ABS actuators that may have been manufactured out of specification. This could cause the ABS actuator pump seal to leak brake fluid. This would cause the ABS warning light to illuminate, and if ignored, and the vehicle continues to be operated in this condition, the brake fluid leak could create an electrical short in the actuator circuit. This could lead to a fire, which could increase the risk of injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the ABS actuator, and will replace as necessary.
On certain motorcycles equipped with a black-coloured clutch master cylinder, the hydraulic clutch system may not be able to generate enough lift to disengage the clutch after being parked for an extended period of time. If this occurs, the driver could lose control of the motorcycle at start up if it is left in gear or when it is first shifted into gear, which would increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will flush the clutch system and rebuild the clutch master cylinder.
Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 126 - Electronic Stability Control Systems. Certain brake Hydraulic Control Units (HCU) may contain metallic debris, which could reduce pump performance and affect Electronic Stability Control (ESC), and may cause the system fail to meet the requirements of the standard. If metallic debris is present, particles may block a pressure valve in the HCU during operation. This could result in a driver experiencing degraded performance of the ESC and related brake systems without warning, which could increase the risk of a crash causing injury and/or damage to property.
On certain vehicles, brake fluid from the master cylinder may leak into the brake booster. Depending on the volume of fluid that leaks, the driver could experience visual and audible warnings due to the low fluid level in the master cylinder. If the vehicle is operated in this condition, the driver may experience increased brake pedal travel, increased pedal effort, and extended stopping distances, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the master cylinder. The brake booster will also be replaced if there is evidence that brake fluid has leaked into the booster.
Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 126 - Electronic Stability Control Systems. Some brake actuator pumps may have been assembled with an O-ring that is damaged in such a way that the brake fluid pressure may not be properly controlled during Anti-Lock Braking (ABS), Traction Control (TRAC), and Vehicle Stability Control (VSC) system activation(s), which fails to meet the requirements of the standard. This could result in a loss of vehicle stability control, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the serial number of the brake actuator and, if necessary, replace the brake actuator assembly.
Certain vehicles may have been manufactured with a defective Anti-Lock Braking System (ABS) actuator.

No risk description available.
Remedy
Dealers will inspect the ABS actuator and, if affected, replace the defective ABS actuator.
On certain vehicles, the parking brake connector clip may be out of hardness specification and could fracture when the parking brake lever is applied. This could result in unintended vehicle movement if the vehicle’s transmission is not in the PARK gear position, or if the vehicle is not equipped with a transmission having a PARK position. Unintended vehicle movement could result in injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will install a revised parking brake cable connector clip.
On certain vehicles, a circlip at the brake pedal hinge may not have been installed at the time of assembly. This could allow the pivot pin to move out of position, which would allow the pedal to wobble, and could fracture the brake pedal pivot through continued use. A fractured hinge would allow the pedal to separate from its pivot, which could lead to impaired brake function and increase 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 add a circlip as necessary.
On certain vehicles, the left front brake caliper may have been cast from an incorrect material during manufacturing. This could cause the brake caliper to possibly crack under an extreme braking application. This could affect vehicle control and increase stopping distances, which could increase the risk of a crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the front left caliper date code and replace the caliper if it is from the suspect casting date.
On certain vehicles, a securing clip at the brake pedal hinge may have become dislodged during vehicle assembly. This could allow the pivot pin to move out of position, which would allow the pedal to wobble, and could fracture the brake pedal pivot through continued use. A fractured hinge would allow the pedal to separate from its pivot, which could lead to impaired brake function and increase 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 add a securing clip as necessary.
On certain vehicles, when the vehicle is parked in cold temperatures for a prolonged period of time, the relay inside the electronic brake booster may freeze. This may result in increased brake pedal effort, which could increase stopping distances, potentially resulting in a crash causing injury and/or damage property.
Safety Risk
No risk description available.
Remedy
An Electric Vehicle certified dealer will reprogram the electrically-driven Intelligent Brake Control Unit software.
On certain motorcycles, the rear brake line joint may have been improperly torqued during assembly. This could cause brake fluid to leak from the loose connection, resulting in a reduction or loss of rear brake pressure. This could increase stopping distances and affect vehicle control, which could result in crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will torque the rear brake line joint to specification and if necessary, fill the rear brake reservoir.
On certain vehicles equipped with a 3.0L diesel engine, hydraulic brake boost compensation and Electronic Stability Control (ESC), the Anti-Lock Brake System (ABS) module may have been programmed incorrectly. If the driver commands the ESC to be off, and then cycles the ignition key off and back on within 10 seconds, the Anti-Lock Brake System (ABS) module may not reset the ESC system back to active status. If the system is not active, the vehicle may be inadvertently driven without the ESC system activated, which may increase the risk of a crash causing injury and/or damage to property.
On certain Heavy Duty and Police Pursuit vehicles, the brake pedal pivot nut may become loose, causing the brake pedal to be loose or inoperative. If the brake pedal becomes loose or inoperative, it could interfere with the accelerator pedal, and/or the driver may be unable to safely stop the vehicle through application of the brake pedal, potentially affecting stopping distances and increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the pivot bolt installation to determine whether the vehicle has already received the production remedy. If not, the dealer will add adhesive to the nut, and reinstall the nut at an increased torque.
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 sedan models, a defect in the electronic stability control (ESC) yaw sensor could cause cause the ESC light in the instrument panel to illuminate as well as cause unwarranted activation of the stability control system. This could result in reduced engine power and brake application on one or more wheels, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will verify proper operation of the yaw sensor and update vehicle software.
On certain vehicles equipped with air brakes and rear air suspension, the rear service brake and parking brake air lines could contact the rear axle housing during vehicle operation, causing the lines to wear. Over time, this could result in an air leak in the service or parking brake lines. An air leak in the parking brake lines could result in inadvertent parking brake application. An air leak in the rear service brake line could affect rear service brake performance, potentially resulting in a loss of rear service brake function. These conditions could increase the risk of crash causing injury and/or damage to property:
Safety Risk
No risk description available.
Remedy
Dealers will inspect air lines for damage and repair as necessary, as well as install revised rear brake chambers.
On certain vehicles, engine oil may migrate from the vacuum pump into the brake booster. Prolonged brake booster diaphragm exposure to engine oil could cause the diaphragm to fail, leading to a loss of brake booster assist. This may result in increased brake pedal effort, which could increase stopping distances, potentially resulting in a crash causing injury and/or damage property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the brake booster grommet for the presence of oil. If no oil is found, the vacuum tube assembly will be replaced. If oil is found, the vacuum pump, vacuum tube assembly, brake booster and master cylinder will be replaced.
On certain motorcycles, the primary cup seal in the rear master cylinder could tear. If this were to occur, brake fluid pressure to the rear caliper would be reduced, and the performance of the rear brake would be degraded. This would increase stopping distances and could affect braking control, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the rear brake master cylinder piston assembly.
On certain motorcycles, the front brake hose could fatigue and crack due to tight left turning manoeuvres. The outer protective covering of the brake hose may kink due to excessive bending stress, causing the outer jacket of the brake line to crack, potentially resulting in a brake fluid leak. If brake fluid leakage occurs, the maximum front brake pressure may not be able to be applied. This would also increase stopping distances and could affect braking control, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will replace the front brake hose with one of an improved design.
