As part of normal operation of the air conditioning system, condensation will accumulate in the condenser housing behind the dashboard. A drain is incorporated so that excess water can drain out. This drain hose can become plugged, the accumulated water can leak onto the airbag control module. This can result in an electrical short in the control module. If this were to occur the airbags could become disabled or deploy unexpectedly. Improper airbag operation increases the risk of personal injury and/or a crash. The power steering assist could also become inoperable resulting in increased steering effort. Dealers will seal the air conditioning condenser housing and install a protective cover on the airbag control module to correct this concern.
Southeast Toyota Distributors, LLC (SET) is recalling certain vehicles equipped with 18" Maverick Alloy Wheels. The spare wheel requires a different style of lug nut to attach it to the vehicle. These lug nuts were not supplied when the vehicle was first sold. Use of the incorrect lug nuts when mounting the spare wheel can cause it to loosen over time, increasing the risk of a crash. Dealers will perform the following remedy for this concern: Install a Warning Label on the spare tire/wheel, supply a bag containing proper spare wheel lug nuts, place an Owner's Manual Addendum in the vehicle's glove box.
An electrical short can develop in the windshield wiper switch assembly. As a result, the wipers may not function as expected. If the driver's visibility is reduced the risk of a crash increases. Dealers will replace the wiper switch assembly in affected vehicles to correct this concern.
The shift lock system prevents the shift lever from being moved out of the Park position unless the brake pedal is depressed. These vehicles are being recalled because the shift lock solenoid could fail rendering the shift lock system inoperable. If the shift lever is moved out of the Park position when the brakes are not applied the vehicle could roll unexpectedly, increasing the risk of a crash. When parts become available, dealers will replace the shift lock solenoid to correct this concern.
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.
