    My Prius is 07 with 146k in southern California, for two days every morning I took a short trip to a store then when driving back home the prius battery lost bars fast and I lost power with all sorts of warning lights. Then I drive off with no problems for the entire day. I disconnected the aux battery and that reset the Error codes, I checked the inverter pump and works properly, I checked the aux battery and shows 12v when off and 13.9v -14v when on. This happens every morning so I suspect it's the aux battery. 3months ago my dash lights went out and rebooted the car with no problems.

    you are still within CA warranty on the hybrid battery, if that's the problem, the dealer will give you a new one. Why are you resetting the codes? When this happens, bring it to the dealer before your warranty ends at 150k miles.

    Well this morning it did the same thing and noticed that the battery discharges in less than 5min from green to purple when idling. I'm now going to read the codes to confirm that it's the main HV Battery.
