Two of the main control modules for the hybrid drive system are the Inverter Module and the Intelligent Power Module (IPM), which is located inside the Invertor Module. The IPM can operate at temperatures high enough to damage its electrical solder connections. Damaged solder joints can result in illumination of warning lights, various drivability concerns, and possible stalling of the hybrid drive system. Dealers will replace the IPM on affected vehicles to correct this concern.
If the nuts for adjusting the rear wheel alignment are improperly tightened during service, the rear tire rod may develop unwanted movement and rust, leading to thread damage and eventual failure. Failure of the rear tie rod could cause a loss of vehicle control, increasing the risk of a crash. Dealers will inspect the tie rods and replace any that have rust or corrosion on the alignment adjustment threads. All rear tie rods will then be encased in an epoxy to prevent future environmental damage.
If the access doors are repeatedly and forcefully closed, over time the screws attaching the seat belt pre-tensioner to the seat belt retractor can loosen. If the screws loosen completely, the seat belt pre-tensioner and the retractor spring cover could detach from the seat belt retractor. If this were to occur the seat belt pre-tensioner will not perform as designed, increasing the risk of injury in a severe crash. Dealers will inspect the seat belt assembly and the screws will be secured or the seat belt assembly will be replaced as necessary.
Many late model vehicles use electronic controls for the power steering assist. These Yaris vehicles are being recalled because an electrical relay in the power steering control module could short circuit due to moisture contamination, resulting loss of power steering assist. Without power steering assist, the vehicle will become hard to steer, increasing the risk of a crash. Dealers will replace the power steering control module to correct this concern.
82 vehicles manufactured by Eldorado National-Kansas (ENK) may have a condition where the left rear shock absorber can contact the fuel filler neck. These vehicles are all modified versions of the Toyota Sienna. The resulting damage could cause a fuel leak, increasing the risk of a fire. ENK dealers will relocate the rear shock absorbers and add a spacer to correct this concern.
The brake booster pump contains a compartment filled with nitrogen gas. This nitrogen gas can leak into the brake fluid causing reduced hydraulic pressure during application of the brakes. Reduced braking efficiency can increase the risk of a crash. Dealers will replace the brake booster pump assembly as necessary to correct this concern.
Certain FJ models were equipped with auxiliary driving lights mounted to the front bumper. If these lights are used in conjunction with the high beam headlights, the total illumination exceeds federal safety standards. The resulting glare to oncoming traffic could reduce visibility, increasing the risk of a crash. Dealers will replace the original 55 watt auxiliary driving light bulbs with 35 watt bulbs to correct this concern.
Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator module found.
Vehicles have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle. These models are being recalled because the incorrect vehicle weight rating is shown on the information label. This could result in vehicle and tire overloading, increasing the risk of tire failure. Owners will be provided an updated vehicle weight label to correct this concern.
The driver and passenger front seat belt retractors are located in the rear doors. If the rear doors are repeatedly closed with excessive force the door panel may crack. If cracks occur around to lower seat belt retractor anchor the retractor could come loose, increasing the risk of injury in the event of a crash. Toyota is currently developing a remedy for this problem.
