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 have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle.

Owners will be provided an updated vehicle weight label to correct this concern.
