Does anyone else get this? I'm wondering just how small that second battery is?

If you do short drives you'll see it more frequently. If you take a longer drive it should go away. If it doesn't, you probably have a failing battery.

I was told by almost everyone on this Forum that it was the Aux Battery. But, after testing at the dealership, they replaced the "Intelligent Batter Sensor" . I did a good trickle charge, to make sure the batteries were topped off, after the fix. Everything has worked as designed, after that.
