Has anyone gone through the process of cleaning the air ducts for the HVB? (I did some searches but didn't find a thread... apologies if there is one)
I'm suspecting a cooling issue with my 2017 Energi's HVB, as I have an experience of driving somewhere that uses most of the HVB - somewhere around 30% battery the battery will suddenly drain quickly and go to hybrid mode, then after the car has sat around for 15+ minutes I come back and find the battery back into the 3D icon (EV capable) with ~20%. I'm assuming there's something going on with thermal management here, and I've never done anything to clean the HVB cooling ducts. Do you need to use something like a pellet brush to brush out the inner ducts or is it just a process of using shop vac/compressed air?
