Summary

Regionletter: in these vehicles, toyota has received some reports where the intelligent power module (ipm) located inside the inverter assembly of the hybrid system may fail. This condition is indicated by hybrid system diagnostic trouble codes (dtcs): p0a94, p324e, p3004, and/or p0a1a. If one or more of these dtcs are detected, various warning lamps on the instrument panel will also illuminate and the vehicle will enter fail safe mode. Although the hybrid inverter assembly is covered by toyota’s new vehicle limited warranty for 8 years or 100,000 miles (whichever occurs first), we at toyota care about the customers’ ownership experience. Toyota is now extending the warranty coverage for repairs related to failure of the intelligent power module (ipm). Please see the warranty enhancement program details for additional information.
