Start/Stop, Aux switches dash message(s)

Hooked
Been driving the JT daily on the freeway and some trips more than 30 minutes at 65+, these messages still won't clear:

1. Start/Stop Not Ready Engine Temperature Too Low (it was 75 today)

2. Start/Stop Not Ready Battery Charging

3. Aux Switches Temporarily Unavailable Battery Charging

Anyone else have this issue? only 16k milesm could the batteries be bad already?

My guess would be the aux battery
 
Separate the negative cables from main battery, take the IBS box off the negative post.

Check each battery individually, it could be either/or and dragging the aux battery down.

Been there done that. You’ll want to replace both batteries. Mine went out at 20ish thousand miles.
 
It’s the batteries going. Have had the “aux switch’s unavailable, battery charging” message for a few months now. Tested the battery’s and they have a low state of health. Just to lazy to want to replace them lol
