Good idea to check Inverter Controller Fluid, mine was below minimum mark, just added about a 1/2 cup of ICE Coolant to the reservoir not worth messing around diluting it. :) Paul
My 2014 C-MAX Hybrid recently began making this loud sound that seems to be coming from the inverter. Does anyone know how to fix this or is the inverter shot? Check video for audio: https://www.youtube.com/watch?v=00wLT2mRXMQ
