    Hi everyone! Just purchased a 2015 Prius V last week with 57,000 miles. I was able to drive it home fine, but after sitting in the car for about an hour in ready mode with my phone charging, the car cut off and won’t cut back on. I thought it might be the 12v battery, but all of the interior lights turn on. Additionally, the care made some really weird noises while off and the check engine light came on a couple of times (as well as all the indicators on the dash flashing). Any idea what the issue is? See linked video for all of the weirdness the car exhibits when attempting to start it:

    test the 12volt battery anyway, lites don't take much power, closing relays does

    I had a lot of weird dash indicator lights and odd behavior when my 2012 Prius V 12v battery (in rear right, access thru hatchback, under the cover) was about 6 years old and didn't have sufficient voltage. Replaced it and it everything worked perfectly again.

    Now on a PC, I see the video and it's definitely symptomatic of a flat 12V auxiliary battery.
