    Hey all! I've been having what I believe to be issue with my HV cooling fan. It tuens on, but only to speed 2. The battery gets super hot! After so much research, I can not find a reason. So, until I can get it properly diagnosed, I found a SUPER HELPFUL APP. Hybrid Assistant....it runs in the background unlike Dr. Prius, and this video expains a lot about the battery temp limits. Hope someone finds this as helpful as I have.

    Did you ever find out the cause of the battery overheating? Thanks.
