Hi, my name is ***** ***** am happy to assist you. I will need to know some more information before I can give an accurate answer. What is the battery percentage remaining? Is the "HV reserve" light or warning the only message on?

Expert:  Michael Warfield replied 8 months ago.

Regardless of any other messages, any warnings pertaining to the HV battery should be taken seriously. I would take the vehicle into the dealer first chance you get. If it was serious enough though, the high voltage battery would of already disconnected power to everything and not allowed the car to run. Let me know if you need any more help before you decide to rate me, thanks!
