On certain vehicles, the steering intermediate shaft splines may have been improperly hardened. If the steering wheel is held firmly on the steering lock while turning sharply at low speeds, the splines could deform and wear, causing a backlash in the steering system. The splines could also become fully stripped, resulting in a potential loss of control causing a crash resulting in injury and/or damage to property. Correction: Dealers will inspect the vehicles and replace affected steering shafts.
On certain vehicles, the electrical water pump assembly, used to circulate coolant through the hybrid components, may fail. If this were to occur, coolant would stop circulating, illuminating various warning lights in the instrument panel of the vehicle. In certain cases, the water pump motor could short-circuit, causing the hybrid system to stop functioning and the engine to stall. A loss of propulsion, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing personal injury and/or property damage. Correction: Dealers will replace the electrical water pump.
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.
On certain vehicles, the connection at the intermediate shaft or the intermediate extension shaft may become loose or the intermediate shaft sleeve may develop a crack under certain operating conditions. The connection may separate or the shaft sleeve may fracture, which could result in the loss of steering control and an increased risk of a crash. Correction: Dealers will replace the steering intermediate shaft. In addition, the dealer will inspect the sliding yoke and the intermediate extension shaft and replace them if necessary.
On certain vehicles equipped with a light emitting diode (LED) stop lamp, there is a possibility that silicon oxide may be generated on the surface of the contact point inside the stop lamp switch. Consequently, current may not flow at the contact, causing the stop lamp to become inoperative. The loss of stop lamps would result in failure to warn following drivers that the vehicle is braking and/or is stopped, which could lead to a vehicle crash. Correction: Dealers will replace the stop lamp switch.
