Sensors on board the vehicle detect the presence of a seated passenger and may not be calibrated correctly. These sensors determine whether the vehicle's airbag systems should be deployed in the event of a crash and may turn them off, causing risk of injury to a passenger. Dealers will recalibrate the vehicle's passenger sensors free of charge.
Toyota Prius Recalls
Southeast Toyota is recalling certain vehicles because the seat heater element may become damaged as a result of compression of the seat cushion. The damaged element could short causing burning of the seat cushion, increasing the risk of personal injury. Dealers will disconnect seat heaters with copper strand elements and refund the purchase price of the seat heater accessory to correct this concern.
These vehicles are being recalled because one of the electronic components of the hybrid control system, the Intelligent Power Module (IPM), can fail internally. This module is located inside of the inverter module and contains transistors that may become damaged from high operating temperatures. If a failure were to occur, various warning lights would illuminate and the vehicle would only operate in a reduced power mode for a short time or stall completely, increasing the risk of a crash. Dealers will update the software in both the motor/generator control module and the hybrid control module to correct this concern. If an inverter module were to fail before the software updates are performed, it would be replaced as part of this recall.
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.
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.
Vehicles that have had accessories added to the seats such as seat heaters, seat covers or DVD headrests may not have the occupant sensor system of the passenger seat calibrated properly. This can affect passenger air bag operation in a crash. Dealers will test the sensitivity of the occupant detection sensors and recalibrate them as necessary free of charge to resolve the concern.
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.
The steering linkage may loosen, resulting in reduced electric steering assistance when making a left turn. Loss of power steering assist may increase the risk of a crash. Dealers will replace the nuts securing the steering linkage to correct this concern. This recall is expected to begin in early July 2011.
These vehicle were sold without the required load carrying captivity modification label. Dealers will mail the corrected label to vehicle owners. Owners have the option of requesting that the dealer install the label. This recall is expected to begin on May 27, 2010.
