Certain electrical circuits in the airbag system are susceptible to an internal electrical short circuit. A short circuit can create excessive current flow, damaging the electrical circuit. Damaged electrical circuits could result in an inadvertent deployment of the front airbags and/or seat belt pretensioners. This could increase the risk of injury and the possibility of a vehicle crash. Dealers will install a supplemental wire harness containing an electrical filter between the airbag control module and its wire harness to protect the control module from this electrical interference.
Vehicles currently registered, or first sold in states where salt is used to de-ice the roads, are being recalled because a metal plate which helps secure the spare tire may rust excessively and break. This rust condition is a result of an insufficient coating of anti-corrosion material during the manufacturing process. If the plate were to break, the spare tire would come loose and fall from the vehicle while driving. Toyota is currently developing a remedy for this recall and will notify owners of affected vehicles when the remedy is in place. This is expected during December of 2012.
The affected vehicles have a steering intermediate extension shaft manufactured with metal splines that may have an insufficient hardness. Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash. Toyota dealers will inspect the extension shaft and replace if necessary.
During manufacturing, a scratch may have occurred inside of the electrically driven water (coolant) pump at the coil wire, resulting in corrosion. The corroded wire may break and the water pump could stop. The corroded coil wire could cause a short circuit in the pump resulting in a blown fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash. Dealers will replace the electric water pump to correct this concern.
Toyota and General Motors are recalling certain models because the power window master switch assembly in some of these vehicles was built using a less precise process for lubricating the internal components of the switch assembly. Irregularities in this lubrication process may cause the power window master switch assemblies to malfunction and overheat. This could result in the switch melting or possibly catching fire. Dealers will inspect and repair or replace the master window switch as necessary.
Toyota is recalling certain model year 2006 through 2011 RAV4 and 2010 Lexus HS250h passenger vehicles. If nuts securing the rear tie rod are not tightened properly during service, unwanted movement and rust can develop leading to component failure. Failure of the rear tire rod will cause an abrupt change in the vehicle's alignment. This could lead to a loss of vehicle control, increasing the risk of a crash. As of this writing, remedy information is not available for this recall.
The tire information label contains inaccurate spare tire size and cold inflation pressure information. This could lead to improper spare tire use or replacement, which could result in tire failure, increasing the risk of a crash. Gulf States Toyota will send each owner a corrected tire information label to correct this concern.
Over time, vibration of the steering wheel while driving may damage the spiral cable assembly (clockspring). This is the electrical connection between the driver's airbag and the vehicle wiring harness. If damage occurs, the airbag warning lamp will illuminate and the driver's airbag may become deactivated. In the event of a crash, the driver's airbag may not deploy as expected, increasing the risk of personal injury. Dealers will replace the clockspring assembly to correct this concern.
During assembly, the electrical contacts of the stop lamp switch may have been contaminated with silicone grease, causing increased electrical resistance in the switch. This could result in: Illumination of warning lamps; a no start condition; the shift lever may not shift from the Park position; and/or inoperative brake lights. Inoperative brake lights would fail to warn other drivers the vehicle is slowing or stopping, increasing the risk of a crash. Dealers will replace the brake light switch to correct this concern.
A propellant with an incorrect specification may have been used during assembly of the side curtain airbags. As a result, one or both side curtain airbags may not deploy in the event of a crash. Failure of a side curtain airbag will increase the risk of injury. Dealers will inspect and replace the side curtain airbag assembly as necessary to correct this concern.
