DP: The Customer Confidence Program is a component of a class action settlement that includes several elements of coverage. The Customer Confidence Program provides coverage as it applies to the Intelligent Power Module (IPM). The specific condition covered by this Customer Confidence Program 23TE03 is failure of the IPM located inside the inverter assembly of the hybrid system indicated by DTCs P0A94, P0A1A, P324E, and/or P3004. If any of these DTCs are detected, various warning lamps on the instrument panel will also illuminate and the vehicle will enter Fail Safe Mode.
