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 Prius (ZVW30) and Prius+ (ZVW41) models affected by this recall were manufactured between 5. 2. 2014 – 6. 11. 2015 (Prius) and 12. 9. 2014 – 24. 3. 2016 (Prius+).
