Common questions
What does the inverter do?
It converts battery power to run the electric motor and sends power back to charge the battery. It is a key part of the hybrid system.
Why did mine fail?
Heat, a failing coolant pump for the inverter, or age. Some models are known for it, so ask whether yours has a recall or extended warranty.
Can it be repaired?
Sometimes. Some firms repair or rebuild inverters for less than a new one. Ask about options and warranty before deciding.
