    The Hybrid battery does not charge. It has happened twice so far and I am concerned that this will become a larger issue. The yellow triangle does not appear. In fact the only indication is that the battery bars drop to two and the charging bar indicator shows no charge . When I stop and turn the car off then turn it back on, the charging goes back to working normal. Has anyone have this happen in their Prius? I have a 2010 IV with 97000 miles.

    The battery does not always charge, so I’m not sure exactly what you mean

    The hybrid battery does not indicate an increase of bars when braking. The battery drains down to 2 bars and does not increase. The charging indicator does not show charging while driving/braking. Shows no codes or problem lights on dash.

    so, no matter how far you drive, it never comes up from 2 bars unless you shut down and restart?

    Based on your join date, I'm assuming you have plenty of experience with this car so it's not pilot error. I think I'd be taking it to Toyota or a trusted hybrid specialist to let them check it out. Something sure sounds strange.

    So, you're saying this display never goes into the CHG portion? It should definitely enter this portion when braking, and possibly during coasting also.

    If you have your origional 12v battery, I'd start by getting a new one and charging it.
