Hybrid IPM:  Repeated driving under certain identified high-load driving patterns (e.g., from a stop, applying nearly full throttle and then gradually further accelerating to full throttle) could cause higher thermal stress in specific transistors in the IPM, resulting in damage to those transistors over time.  There is a possibility of the hybrid system shutting down instead of entering a failsafe driving mode which could result in the vehicle losing motive power while driving at higher speeds, possibly increasing the risk of an accident.  NOT ALL VEHICLES IN THE MODEL YEARS ARE INVOLVED.
