RepairPal Expert Overview
The vehicle may operate only at a reduced power level or stall without warning.
Toyota will notify owners of affected vehicles beginning late February, 2014. If you don't receive notification you feel you should have, please contact your dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call.
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.
