Hybrid warning light on temporrarily
Well it got worse to the point where the light is on consistently. Turns out the ISG failed. I'm surprised because I thought this part is supposed to last longer than a regular alternator.
The next oddity is the dashboard dimmer is messed up. When I turn the headlights off, I think the dashboard should dim to full bright. Instead, it stays dimmed to night mode, the same as when the headlights are on. So I have to dim it up with the roller switch every time.
I think this behavior started at the same time as the hybrid light, but I'm not positive. I wonder if low voltage from the ISG damaged the computer somehow.
