2011 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.
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.
