Sorry to resurrect a slightly old thread. My 2020 just started getting the "Start/stop not ready, battery charging" message. I had been driving for approx an hour with ESS off (mostly stop and go traffic). Seems like the battery would have charged after an hours driving.
I am still under warranty so I am thinking I am better off not using a trickle charger and that it makes more sense to take (fairly new) JL in for dealer to check batteries via warranty. A couple of questions for the more knowledgeable Jeep experts:
Does it make sense not to trickle charge? Could this mask the problem?
and second question

For reference my voltage (from what I understand based on shared batteries voltage) after the aforementioned hour of driving was 14.1V
HELP: How urgent is it for me to get this looked at under warranty?

I have read a lot of threads about dying ESS battery causing Jeep not to start. I don't want to get stuck. Is it urgent to get this looked at under warranty or can I delay a month or so without worries about getting stuck because my Jeep is a 2020 and should have the fix referenced (such that rig will start if Aux battery is dead)?There's a fix for the 2018's and all subsequent model years have that fix built in such that if the Aux battery is dead, the rig won't start the first time the Aux battery problem is detected, but all subsequent attempts to crank will switch to the main battery while the ESS off light is illuminated on the dash.
