I was on my way to a friends house yesterday, when I got into my Clarity and tried starting it, to no avail. Tried several times, and noticed that the start button was flashing red. Tried turning the car off, but that did not seem to work either... so I disconnected the negative battery terminal for a minute, and tried restarting the car. Now, it just showed a graphic on the display which tells one how to put the car into accessory mode. At this point I am suspecting the 12 volt battery... but wanted to see what happens if I connect the car to my lvl 2 charger. It took several presses of the charge door release button, before it would open. When I connected the lvl 2 charger, I couldn’t get the car to take a charge. Luckily for me, I have a 12 volt car battery charger, which I used to charge the 12 volt battery for several hours. The car started fine after that, but did have all sort of warnings pop up on the display for TPMS and other systems. Question - under what circumstances does the 12 volt battery receive a charge? I was working from home this week, and the car sat for 6 days without being plugged into a lvl 2 charger. My main E.V. battery was at 90% capacity. Now, I also have an Owl Dash cam, but the camera supposedly goes into low power mode after 2 days - but that could have contributed to the problem, especially if the 12 volt battery was already weak or failing (I’ve only had the Clarity for little over a year and the car was bought new).
