2021 JL with Start/Stop but NO AUX battery??

[blazer]

Couple weeks ago got the "No AUX switches, battery charging" message. Went and got the small portable lithium battery jump kit as Eddie recommended. Went to O'Rilley's and got the small AUX battery. Had to use the jump start twice so started the process of changing
the AUX battery, but went through the tire and fender removable method, did not want to mess with electrical. AND...got the small box
enclosure off and no AUX battery. So not sure what to do. ideas???

Do you have the 3.6? My 21 with the 3.6 has a bigass battery under the vehicle. When I get the battery charging message I just drive it a while and all is well with the world.

JL Wranglers with etorque will NOT have an auxiliary battery.

Thanks, yes, 3.6 with etorque. Battery voltage display ranges from 12.4 at start up to 14.0. Also have trailer package which indicates larger size battery. And reviewed warranty, 36 months or 36 k. I have 35,842 miles, so still under warranty.
So,,,go to dealer or just get new battery from O'Rileys????? Thanks

Yeah, the etorque has a huge 48 volt battery in the undercarriage.

I would definitely take it to the dealership and have them replace it under warranty. IF it's the big 48v battery that's your problem, it'll cost a pretty penny to replace.

Thanks, will take to dealer.

Go to dealer. Battery will be replaced under factory bumper to bumper warranty

Get it to the dealer before your clock turns 36,000. If they don't have one in stock, you're on the list with the mileage being under.


On a side note, if I dug into changing the AUX battery from either direction and didn't find a battery, I'd be PISSED.

OH, if you have to get a 12V battery on your own, get a Bosch, 4 year warranty, everyone else seems to be a 3 year now.

So....took it to dealer yesterday morning, got a call today that they replaced the top normal 12 volt battery and all is good.
Hope that is all it was and will pick up tomorrow morning and see. Thanks for all the advice.
