On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury. Correction: Depending on the vehicle model, dealers will either replace the passenger frontal airbag inflator, or replace the airbag assembly. Note: Canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected.
On certain vehicles, the fuel delivery pipes in the engine compartment may have been produced with particles from the anti-corrosion plating on the gasket seating surface where the fuel pressure sensor is installed. This could affect the sealing properties of the gasket seated between the pressure sensor and the pipe, potentially resulting in a fuel leak. A fuel leak in the presence of an ignition source could result in a fire causing injury and/or property damage. Correction: Dealers will replace the gasket and repair the gasket seating surface.
On certain vehicles, the bolts used to secure the housing and sprocket of the intake-side Variable-Valve Timing (VVT) gear assembly could loosen. If this occurs, the VVT gear will not control the intake valves correctly. In some instances, the VVT gear housing and sprocket could separate, causing the engine to stall. Engine stalling would result in a loss of vehicle propulsion which, in conjunction with traffic and road conditions, and the driver’s reactions, could increase the risk of a crash causing property damage and/or personal injury. Correction: Dealers will replace the VVT unit with an improved version.
On certain vehicles, the wiper arm securing nuts could have been insufficiently tightened during assembly. If the movement of the wipers is restricted by an external load, such as heavy snow on the windshield, the wiper arms could slip and one or both wipers could become inoperative. If this occurs, driver visibility could be reduced, which could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will clean the mating surface of the wiper arm and motor shaft and install improved wiper arm nuts.
On certain GS 300, GS 300 AWD, GS 350, IS 250, IS 250 AWD and IS 350 vehicles, the fuel pressure sensor connected to the engine fuel delivery pipe may not have been sufficiently tightened during vehicle assembly. Should the pressure sensor loosen, fuel could leak past a gasket used in the connection between the sensor and pipe, and through the threaded portion of the sensor. Fuel leakage, in the presence of an ignition source, could result in a fire causing property damage and/or personal injury. Correction: Dealers will inspect for fuel leakage from the threaded portion of the fuel pressure sensor. If there are no signs of a fuel leak, the fuel pressure sensor will be tightened to specifications. If a fuel leak is confirmed, the gasket between the sensor and the fuel delivery pipe will be replaced, and the sensor will be tightened.
On certain vehicles, the accelerator pedal may become stuck in the wide open position due to an unsecured or incompatible driver's floor mat. A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death. Correction: Dealers will reconfigure the shape of the accelerator pedal. Certain models will also have the shape of the floor underneath the accelerator pedal modified and/or a brake override system installed.
