On certain Vantage Mobility International wheelchair accessible vehicles built on Chrysler Pacifica platforms, the rear wheel brake lines may have been inverted during the conversion process. This could cause an incorrect application of the Anti-lock Braking System (ABS) under certain circumstances, 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 and re-route the brake lines as necessary.
Certain vehicles may have incorrect Electronic Stability Program (ESP) software installed. In the event a driver assist system (e.g. adaptive cruise control) initiates automatic braking and aborts again during the early stage of brake pressure increase, a low residual pressure could remain in the hydraulic brake system. As a result, the braking system could continue applying minimal pressure with the brake pad contacting the rotor, and may heat up when driving is continued. Constant brake pad application over longer periods of driving could lead to the brake fluid heating in the brake caliper, resulting in higher pressure in the brake system. This could reduce brake performance, and increase the risk of a fire causing injury and/or damage to property.
On certain vehicles equipped with 3.5L V6 GTDI EcoBoost engines, the electric vacuum pump (EVP) may fail due to moisture entry through the engine vacuum harness. Failure of the EVP may result in reduced brake assist immediately after first start up, and depending on the driver’s reaction, may result in extended stopping distance which may increase the potential for a low-speed collision causing injury and/or damage to property.
On certain vehicles, the Brembo electric parking brake calipers could contain an improperly manufactured internal gear that could break under load. If the gear broke, the parking brake would not release and could result in an inability to move a parked vehicle. If the gear broke prior to full parking brake engagement, the parking brake could have less holding force than intended, which could result in unintended vehicle movement, increasing the risk of injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Tesla Service Centers will replace the defective park brake calipers.
On certain motorcycles, the software of the Hydraulic Control Unit (HCU) which controls the Anti-Lock Braking System (ABS) may be incorrect. If a braking event were to trigger the ABS, the motorcycle may not brake as intended, which could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will either reprogram the HCU with the correct software or replace it.
On certain motorcycles, an electrical connection can be created via the brake line between the anti-lock brake (ABS) modulator and vehicle ground. If the wiring harness is frayed and contacts the ABS modulator, there is a potential for the brake line to conduct electricity, causing overheating and ultimately melting the brake line. This can result in failure of the brake system circuit, increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the wiring harness and re-position the wiring harness for the engine control unit. Additionally, dealers will add and attach a ground cable to the ABS modulator and mount it to the motorcycle’s frame.
On certain vehicles, defective brake line connections could cause brake fluid to leak from connection points. Over time, this would cause the brake fluid level in the master cylinder reservoir to become low, illuminating the low fluid level warning light. If the vehicle is operated in this condition, reduced brake function may result, extending stopping distances and increasing the risk of a crash causing injury and/or damage to property.
On certain vehicles, the diaphragm in brake booster may unseat due to a manufacturing defect. This could result in a vacuum leak in the brake system and a reduction or loss in power brake assist, which would increase pedal effort, and extend 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 vehicle brake system’s booster assembly.
On certain vehicles equipped with an electronic air dryer, the operating parameters may have been set incorrectly. This could allow condensation into the air brake system, potentially affecting brake system function in cold weather conditions and increasing the risk of a crash causing injury and/or damage to property.
On certain vehicles, the master cylinder brake lines may crack and develop a leak. Loss of brake fluid from one brake line may result in reduced vehicle braking performance, and a complete loss of brake fluid from both lines may result in a loss of braking capability. This would increase the risk of a crash causing injury and/or damage to property.
On certain vehicles, a fault within the antilock brake system (ABS) may cause the module to fail during ABS and/or electronic stability control (ESC) activation. This will cause warning lights for ABS, brake and the ESC systems to illuminate. If this happens, the brake system related vehicle stabilizing functions (ABS/ESC) may not be available, increasing the risk of a loss of vehicle control and could lead to a crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will update the ABS control module with improved diagnostic capability to detect insufficient PCU ground connection. ABS modules with insufficient ground connections will be replaced.
Certain vehicles equipped with an anti-lock brake system (ABS) and without electronic stability control (ESC) may not comply with Canada Motor Vehicle Safety Standard (CMVSS) 105 - Hydraulic and Electric Brake Systems. The brake system indicator tell-tale may not illuminate during the lamp function check when the ignition is initially turned to the “ON” (run) position, which is contrary to the requirements of the standard.
Safety Risk
No risk description available.
Remedy
Dealers will correct the coding of the instrument cluster software.
On certain vehicles equipped with the M270 gasoline engine, the connection piece from the vacuum line to the brake booster may break. If this occurs, the brake booster would no longer be supplied with vacuum which could increase pedal effort, and extend 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 vacuum line from the brake booster.
On certain motorcycles, an electrical connection can be created via the brake line between the anti-lock brake (ABS) modulator and vehicle ground. If the wiring harness is frayed and contacts the ABS modulator, there is a potential for the brake line to conduct electricity, causing overheating and ultimately melting the brake line. This can result in failure of the brake system circuit, increasing the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the wiring harness and re-position the wiring harness for the engine control unit.
On certain vehicles, the front brake calipers may have a torn or extruded caliper piston seal. This could result in a loss of hydraulic brake fluid, which could decrease braking performance and extended 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 the date codes of the right and left front caliper assemblies and check for signs of leaking brake fluid. If the date code falls within the affected range, the dealer will replace the brake caliper assembly. If there are signs of brake fluid leakage, the dealer will also replace the disc brake pads.
Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 135 – Light Vehicle Brake Systems. The brake fluid level sensor may not have been connected during the manufacturing process. In the event that the brake fluid level sensor wire harness is not connected and the brake fluid were to fall below the specified level without illuminating the warning indicator, the vehicle braking performance could be affected, which would increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will inspect and connect the brake level fluid sensor as necessary.
On certain vehicles, the parking brake cables may disengage from the crank lever at the rear caliper. This could cause the parking brake to become inoperative. If this occurs and the transmission is left in a gear other than ‘Park’ while the ignition is on and the driver leaves the vehicle, the vehicle could roll away, increasing the risk of a crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will install a clip at the parking brake cable end to prevent the cable from disengaging from the rear brake caliper crank lever.
Certain vehicles fail to comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 126 - Electronic Stability Control Systems. Vehicles that were brought to a dealer for service may have received an incorrect software update for the Antilock Brake System Stability Control system. The incorrect software disables the engine torque control of the Electronic Stability Control (ESC) system, and if a fault were to occur in the stability control system, including Antilock Brake System (ABS), Traction Control (T/C), and ESC, no warning lamp/indicator would be displayed to the driver. Additionally, no warning lamp/indicator would be displayed when traction control is disabled, or when the Electric Parking Brake (EPB) is applied. A lack of visual warning to indicate these systems are not functioning would be contrary to the requirements of the standard, and could increase the risk of a crash causing injury and/or damage to property.
Safety Risk
No risk description available.
Remedy
Dealers will reprogram the ABS module to correct the non-compliance. Until this software is available, dealers will replace the ABS module.
