Specific transistors in the boost converter of the Intelligent Power Module (IPM) can be damaged by the high thermal stress caused by repeated driving under certain high-load driving patterns (e.g. from a stop, applying nearly full throttle and then gradually further accelerating to full throttle).
This may cause the hybrid system to be shut down without entering a failsafe mode. As a result, the vehicle may lose motive power while driving at higher speeds, increasing the risk of an accident.
The Toyota Auris HV (ZWE186) models affected by this recall were manufactured between May 3, 2014, and December 2, 2018.
