What can fail
A control board in the hybrid system inverter can fail while driving, causing warning lights to appear. The vehicle usually enters a reduced-power mode, but in some cases the power supply fuse blows and the hybrid system stops working entirely, causing loss of engine power.
What the fix does
Dealers will inspect the Intelligent Power Module and replace it if needed.
