New Warning Message

[Mikeylikesit]

I'm having the same issue on my 2022. Only has 6,000 miles on it. I get the aux switch warning every time I turn it on, and have to jump it about every-other month. I pretty much only drive it on weekends so it sits quite a bit and I installed a noco genius on it, but it seems like the battery dies faster than the noco can charge it and I still have to jump it anyway. I plan on trying to get the battery replaced under warranty, so hopefully that takes care of it

Had same problem. Dear let replaced battery under warranty.

I just had this "Aux Switches Temporarily Unavailable Battery Charging" last week in my 2022 with 11k miles. Took it in when doing an oil change and they covered it under the Jeep Wave 3yr/36k warranty for free. Easy fix.

I did check my voltage using a Fluke meter and my resting voltage (engine off) was 12.35V (should be 12.6+) and with the engine on it was 13.8-14.4 indicating a charging voltage (14V is normal with 14.4 as the max charge for this AGM battery) basically this looks like a FCA “factory special” battery so I am not surprised it failed so soon.
I bought a jump start pack based on a test video on the Project Farm YouTube channel:
YASPER 4120 Jump Starter for $79.
I found that if you put it in diagonally it fit in the lower cubby of the armrest area with the alligator jump start clips. This keeps the pack a bit more temperature stabilized and might make it last longer.
New battery they put in is a MOPAR 36 month free replacement battery, it showed 13.63V resting voltage. Guess this will kick the can down the road another 36 months.
