Hi, after charging my 2018 Prius phv I ran the front windscreen blowers while the charging lead was still connected.
Due to the good old UK weather and heavy interior mist I had to press the start button a few times as it turned itself off after approx 5 minutes.
This resulted in being unable to start the vehicle in either ev mode or combustion mode as the 12v battery was flat.
I managed to jump start via leads to my brothers car.
My question is has the 12v battery failed or require replacing or is it just incapable of demisting a windscreen?
Thanks in advance for any help you can give.
