Due to variations in the circuit characteristics of the Intelligent Power Module, higher operating temperatures may result in internal solder degradation. Eventually this will cause heat damage to the Intelligent Power Module with illumination of various warning lights on the instrument panel. In most cases, the vehicle will enter a fail-safe mode, resulting in reduced driving power in which the vehicle can still be operated for short distances. In limited instances, the fuse of the power supply circuit could operate, causing the hybrid system to shut down and resulting in the vehicle stopping whilst being driven.

The inverter assembly is part of the hybrid system. The transistors on the control boards located inside the inverter assembly in some of the involved vehicles were inadequately soldered, and could be damaged by heat that occurs from large current flows that are typical under high-load driving conditions. If this occurs, various warning lamps will be illuminated on the instrument panel and in most instances the vehicle will enter a fail-safe driving mode, resulting in reduced power.
